Compaq Popular Questions, Answers, Tips & Manuals

Try rebooting to see if that clears up the issue. Should. Does not mean it will not happen again if you repeat the operation that caused the BSOD. There is an issue with your OS and you might want to attempt a repair operation if possible

the monitor is bad. its CRT monitor. only googling find relic schmematics you do know right the 2nd anode is at 15,000 volts right? and that is lethal , right>? zero 2nd chances. no photos by you, so no answers ever possible on CRTs. it works like old TVs did, only uses, different cathode drive called DATA. (no tuner or radios inside, like TV) the lines are my guess, caps bad in the Horizontal or vertical drivers for the yoke coils. do not get killed playing with HV ok?

I love posts that use haywire words... really. old Cq61 (310us) is it a 310? for sure, as the service tag shows? no photo of screens, i can promise you that missing photo is worth 1000 words ! does it run with them main battery out on line power AC? it must for as long as you want too. my guess, besides above test 1 on all laptops is to make sure its not overheating. and fan blows, and fan is not packed in lint if the GPU chip overheats it can go nuts. all can,. we run temp monitor program that lets me see all that. but im not teaching that now. this PC has an LED screen so is very good. but if hit, they break easy, super easy. kids playing thowing things at the screen or dropped PC. The pC has and external VGA jack to test the PC on any VGA desktop monitor.. (barrow one for a day)

old compaq. LAPTOP,, 14 years old now, Im amazed it even glows at all with CCFL lamps not dead, wow.. its like a musiem piece. (sorry , grin) (back ground lamps CCFL) NO OS stated by you , XP, ????? why must helpers beg? and wifi , (difficult that) it's not wifi, its just that you use wifi most the time ,SEE? right? in fact we could remove the wifi module. and prove that. disabling wifi is airplane mode, (todays jargon) but means the wifi transmitter is now OFF (airplane safe is THAT) the blue screens tell a lot, and no posted photo of one by you. sad, BSODs we call those blue screens of ***** XP love to do that. (even with Bill Gates on stage) LOL BSOD are hard. Im sure it says 2 words, HALT and DUMP ! here is a list of causes.... for sure 14year old relics (legacy junk)

1. the main battery inside is bad or shorted, remove it run AC , does it, wow, it does, problem solved in minutes flat.
2. the Inverter is shorted (CCFL card) and bom, BSOD
3. bad RAM, BSOD XP fast , try 1 stick at a time.
4. Bad HDD< can corrupte files and XP BSODS in a blink !
5. any thing shorted, remove all usb devices yet?
6. remove extra ram. , unplug CD drive?

all techs know rule 1, is it hardware or software, (this is alway first after #1 above done) to do that we open the CD tray, insert our free LIVE LINUX CD and boot to linux wow it runs for hours ok, proving what, HARDWARE IS BAD if Linux fails its bad hardware (running period correct disk) if linux runs i next do a full HDD test, using the great linux program there to do that. or take that handy dandy, Compac (now HP) 3 disk install disks set and load disk one, does that run? ok even full restore. or does it show HDD errors.? oops HDD is bad. the BSODs are really what. it means the PC attempted to run and ******* instruction. in simple terms, it means a program is corrupted. or tried to do ******* things with memory. that is why test test the PC with a boot CD to see if the PC is ok. see? mr wifi real. sure this can short, but if it is removed and it still BSODs its not this card, its other cards, shorted. or not at all. cards. we call this mini-PCI slot card.

Basically "disconnect" WiFi and then reconnect but select which one, in your case yours. You might have to enter a password if you have set up such I should be good to go.
For more detailed and specific information I would need to know more such as operating system device types Etc.

old PC,, Cq series. cq62-nnnnn you left off the nnnnnn cq62-100, 200 ,300 what? running mS windows 8 HP does not support W8 on this PC so that means you are on your own steam... (you , it and microsoft 100%) forget ACER this is not and ACER PC< at all, (totally different) you could reload w8 , like you did before, now all that works its login password issue, can i presume the screens look ok W8login screens? local login fails, not bios, and not windows live logins fails that is right there are 3 tiers of logins. admin , create a new account and use that or do that and ask at MS how to copy date from dead account to new account, you never said once you had data. if no data on pc, then reload 8, easy no? the newer the OS the more hard it is to get data from that dead account( new permission rules, and hard to do) ask best i can tell, lacking your full model number teh CQ62-400 (newest) had only Windows 7 so how did w8 get there, from whome, and what media. and what install methods. from MS CD? or MS ISO, or from ebay hackers disks/ what? here are the ways, (not data recovery) http://www.pcdied.com/passwords.html

I suggest replacing the fans with new fans. Fans do expire and they need to be replaced.

its old and old pc have problems, just like cars. a desktop NO OS stated, came with VISTA. (a dead OS now) no monitor stated,? series 5000 is obsolete, and near worthless. the unstated monitor is first. if the OSD screens is dead?, yes then the monitor the monitor is BAD all monitors 2000 year and newer have OSD the OSD is the monitors brain inside you push the menu button on the front and behold , this. this pc has onboard GPU/VGA chip (unless upgraded to PCI slot VGA) a key missing fact if true. (but is possible) if running and old CRT monitor , do tell which one (model number) here are all simple tests on that monitor. http://www.pcdied.com/monitors.html#desktop

no pc stated, maker or model #,, sounds kinda DESKTOP>????? no oS stated step one is test the MV4 on a known working pc,!!! why wait, this so basic.... are you using VGA to VGA or DVI to DVI connections?????? the DESKTOP, no sound means the fans are dead and PSU dead. The PSU will run for 1 second and fans run now. if not PSU is dead. if fans do run and stop that means PSU dead or mobo shorts or bad reg on MOBO. or bad ram. strip it down to test that. ok fan runs that means 12vdc good. if stay running, and if PSU stays up, then NEXT TEST IS Screen is it 100 % dead, or do you get text or logos." 100% dead means to me bad VGA card(or chip GPU) if the Hot key for BIOS fails, that means bad POWER/ or bad VIDEO card. the fans run but are silent, I envy you.. sell me your fans.... im 1/2 deaf from Vietnam and can still hear all my fans. my DT has 4 fans min. (it's Alien-ware box++++) CPU, GPU and PSU, and 1 case fan,all must work. do yours? when you power on a PSU, the fans run and stay running if that takes sides off so be it, ever clean the 5lbs of lent seen inside from 5 years, collected? If you dont service any pc, this packs up and the CPU overheats and shuts its self down by DESIGN. why no do that service first. see that CPU, see those fins, see that pack up there. blow it out, outdoors, using CAN-0-AIR mine over heats my GPU fast with lent, my Graphics car runs super hot and fast and lent is NOT ALLOWED here. ever.. old pcs with slow cpu ,, tend to packup slower, well lets say they can run longer with huge lent here. its just slug processor so... that is what it does. recap.

1. fans all run.
2. BIOS dead?
3. screen dead. no words no text at all.
4. MV4 tested on other PC works. proves PC bad.
5. LENT PACK job. as all do every year here, all.
6. Bad VGA caRD. or using wrong port if PC has 2 VGA jacks. !

U have a nasty bug in there. Your best bet is using another computer download the latest malwarebytes program onto a usb stick. Using the hiren disk boot up to the fake desktop, navigate to the usb stick via explorer and run the program and get the latest updates for it at same time. Then run it and clean out the crud that is in the machine causing havoc.When you reboot go back into the program and permanently remove the deleted items that are in the quarantine area.

key board dead , correct. ? even the caps lock key will not toggle its led. my guess is you bought a clone keyboard from china, on fleabay and its dead. as many are, some are wired wrong. the ribbon cable on mine fits to a special connector that likes to break easy, is your broken this locking jack there? is it plugged in upside down? why did you buy a keyboard. was the other dead. when did the keyboard fail. list week last year, or never i bought it for cheap with dead kbd.... there is no HP drivers, HP retired this old PC, after 10 years. so what makes you sure your non HP drivers are any good.? NO OS stated, not even a clue. XP? what I'd do , us boot to a Knoppix v7 live boot(dvd/usbstic)(linux) if the keyboard fails NOW, then its bad KBD. or the jack cable or connector there, (or inserted wrong) or damage. there. buffer chip is blown up with ESD events. (electrostatic discharges) is the keyboard dead in BIOS on ours we hit ESC or F10 and BIOS screens pop power on hammer ESC or F10 or what the screen tells you to hit. the go in to BIOS screens, now test the keyboard. using say the arrow keys to navigate the BIOS menus if the ESC and F10 key are dead that is a bad keyboard. what must work here is the electronics.

1. correct keyboard, some clones will never work.
2. cable not damaged
3. cable not upside down
4. connector there not damage the lock not broken,(easy)
5. the MOBO buffer chip not ESD damaged.
6. BINGO BIOS now works by key commands

Had same issue. Using device manager uninstall the wi fi chip and reboot. When computer restarts you will then be told that there are networks available - select your network, enter your password and it should work!!

do the fans all blow? (all 2 or more) does cd drive eject button work> if not power is gone. why not say what you unplugged, so the helper can be on same page as you..>?? why hide key facts? btw when PC is turned off, it is never off. fully. we must unplug the power cord, and push the power button to get the standby power bus discharged, its on all the time. if fact +_5v-stb is always. on, wall plug connected,. this is the first step in all desktop service, knowing this or things will blow up, for sure. (hot swapping any part but USB) that card is blown up or the PC mobo is blown up. my guess is you hot swapped a PCI card, right? and only the VGA card. right? old compaq the support page still is here. (link at end here) no idea at all what card you have in your hand it has a name and model number im reading your service manual on line now(so can you) and this is a very old COMPAQ, desktop when you open any DT< side cover, we look at all those slots. to see what's, there, it can be ANYTHING, or even empty., if main board has VGA chip the manual shows, it has as mobo VGA 19pin connector try that yet, take out the bad PCI card that sparked. if this fails, the damage can be very serious best I can tell this PC is 13 years old or older. 2003 dated, i think... its is so old it has APG video card slot, yah OLD AGP x4 x 1 so buy one and try it , off fleabay. https://support.hp.com/us-en/product/compaq-presario-s5000-desktop-pc-series/359575/manuals some came with S3 Savage4 pro AGP , new, (options) S3 is out of business now, (merged) id ditch it and go to goodwill store find a pc with COA sticker W7 and newer, XP stinks totally. here. the pc has zero value.. in fact they ship these to 3rd world, for free. so ebay or newegg. (AGP + XP drivers) https://www.newegg.com/Product/Product.aspx?Item=9SIACUE5JF2013&cm_re=agp_video-_-9SIACUE5JF2013-_-Product spend $40 on $5 PC?

what compaq use real models numbers clearly. panel sounds desktop like. ever heard of PC repair shop. we have 1.1 Bilion Computers. on earth now. guess what , vast numbers of shops with certified technicians every where, on earth, were there are people. is the screen dead, ? no text ever, and BIOS dead. if a desktop the PSU is dead.

no PC stated at all, ? (no OS stated? operation system is it windows 95?) is the jack purple as it must be PS2 keyboard. Green is PS2 mouse. so is this a HP PC (unstated) jacked in to a Packard bell PS2 keyboard. possible causes are:

1. bad keyboard, gee it's a relic how can it be good.
2. Windows, set to wrong country keyboard setting
3. Plugged into the Mouse jack green oops wrong. purple good.
4. Packard bell not using IBM codes for keys and will never work on any PC but the PB PC it came off of.use a real USB keyboard? for $3 and end this?
5. here are the official IBM PS2, scan codes.below link.
6. if packard bell used there own key codes then the keyboard is junk on any HP PC, made. (some old makers did
7. Know that Packard bell is not Hewlett Packard, (one is dead)

[link 1] i'd advise testing PB keybrd on other PC but who in the world has PS2 PC in year 2017. I cant imagine it.... ever.

why ask here, and not at hp. how odd that..... this is not HP its a public chat box. here is the correct place to ask, (for SURE) https://h30434.www3.hp.com/

YOU DO know XP is dead right, no MS support now and that the MS plug and play servers are shutting down now . (I have inside info on that) that means what, this moment forward devices you add or install fresh XP things will FAIL. !!! what is XP, ? the Operating system by Microsoft? MS-XP? OS? XP is a problem but can run, off internet safely. no PC stated at all ,just a monitor if the sound is bad, I can see what you have there,at all the speaker in the monitor only need the small cable to do that a 3.5mm phone mini connectors is it. plugged in to your ustated PC , jack marked speakes next YOUR XP OS must have the correct sound card (chip) driver loaded or sound will be dead, in all cases. why not tell pc name and model first then say sounds deAD. then show the device manager page, on sound. XP key strokes are convoluted here. click start, then control panel. click system click hardware. click device manger, (wthew) pant pant... xp sux lucky you I have and old XP laptop (relic) that works like new. but the c-media sound chip fails. (only eMachines his it) when I fresh load XP this chip fails (and others) that is the no and future of XP, what we so is hand load it from the makers support site, but you never once told what PC you have. why? i can teach you how easy. on mine i down load the intel sound chip driver or go to emachine side do same or if HP machine (is it) we get it from there if pc is under 10 years old. if not oops. we must go to intel. or what your MFG codes and DEV codes is , ask me. i can decode them all. ask this is my xp failing on sound the XP cant even tell it is sound just other devices, and is in yellow, Red or unknown words all mean the driver is missing mine below is intel sound. mfg 8086 = intel dev 24d5 is intel's sound chip... so there are 2 ways to fix a fail like below. tell me what PC you have maker and model number full or tell me your codes below. and ill get you your driver.

that message means, you have the unstated PC, set to a super high resolution, that is totally ******* on this old screen, buy a newer screen, or change the resolution. no PC stated , at all. model , is it HP? no OS stated, if XP hit F8 and run safe mode and lower the resolution to 1024x768. only these work,,never higher. 1024 x 768 / 60 Hz 1024 x 768 / 70 Hz 1024 x 768 / 75 Hz 800 x 600 / 60 Hz 800 x 600 / 72 Hz 800 x 600 / 75 Hz 640 x 480 / 60 Hz 640 x 480 / 72 Hz 640 x 480 / 75 Hz 832 x 624 / 75 Hz 720 x 400 / 70 Hz

Might be worth trying the device manager to see if a driver is lurking on the internet somewhere. If not it should be possible to update your sound card. Inserting a card into an expansion slot should switch off any integrated audio.

Of that vintage, could be the back light bulb have burned out or the power supply to them. I'm surprised the HHD is still running on that year model. For the price you can pick one up for on ebay I would replace the the laptop. If you ever have taken one apart and put it back together its an amazing amount of work (see you tube). And while your mashing it all back together there is a good chance it will all short out and be a wash. Put a external monitor on it does it light up? Either way I would get my files off I want off the drive it maybe the end.
