20 Most Recent HP Pavilion A635W PC Desktop Questions & Answers

maybe you need to update the drivers for it have you try that yet?

There are two ways to do this. 1st. Using the recovery partition already installed on your hard drive. 2nd. Creating recovery disc by launching the recovery disc creator. It is highly recommended that when purchasing a new computer a set of recovery discs be may as a factory back up in case your hard drive fails. You should make your recovery discs first. That will require at least 3 DVD blanks. Tell you what, you make the discs first and I'll explain how to use both methods. Click your start button and find a folder called maintenance. The location and name of the folder varies by each computer manufacture as to where they file the recovery disc creator program. I believe It's in the maintenance folder. Open it and there you should find the program. Simply run the program and follow instructions. [email protected] Good Luck

1) There is a such thing as a bad Power Supply. New or not.

2) You may not have all required power cables plugged in.

Besides the ATX main power cable, there is also a 4-pin ATX +12 Volt power cable, that has to be plugged into the motherboard.

This cable,

This is HP Support, and the Motherboard Specifications page,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00069442&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&site=null&lang=en&key=null&product=425875

I would like you to scroll down to the illustration of the motherboard.
To the left of VIA KM400A is a small square. To the top of the small square is printed ATX12V
This is where the 4-pin ATX +12 Volt power cable plugs into.

(The motherboard chipset is the Northbridge chip, and the Southbridge chip.
The VIA KM400A chip is the Northbridge chip. Should be under an aluminum finned Heatsink)

I would also like you to clear CMOS Error codes.
Computer unplugged from power press the Power On button, and hold it in.

Hold it in for a count of 5 seconds. (And I mean at least 5)
Let go of the Power On button.
Do this procedure 2 more times.

This action will clear CMOS Error codes, and reset BIOS back to the factory default settings.
Plug the computer back into power. WAIT 1 minute, then turn the computer on.

Be sure ALL power cables are plugged in, and plugged in tightly.

A) ATX main power cable. (20-pin ATX main power cable)

B) 4-pin ATX +12 Volt power cable

C) All 4-pin standard Peripheral power cables.
1 is for the Harddrive.
1 is for the CD or DVD optical drive, ( Or 2 if more than 1 optical drive)
1 may be used in conjunction with an adapter cable, and used for power to a computer case fan.

3) Make sure the ram memory module/s are seated in tightly. (Module = 'Stick')

You may wish to clean the gold plated contact pins on each ram memory module.
The gold plated contact pins develop corrosion.

Computer unplugged, and you have followed Anti-Static Precautions, remove each ram memory module.
Use a pencil eraser to clean each contact 'strip'.
If you use an eraser on the end of a pencil, refrain from letting the metal band contact the contact pins.
Just takes a few strokes of the eraser on each contact pin.

After you have finished cleaning a contact strip it may look as though you have done nothing at all
I assure you that you have. Doesn't take much corrosion to make a bad contact.
Use air to remove the eraser dust before you reinstall the ram memory.
If air from a can of compressed air for computers is not available, air pressure from your mouth is sufficient.

If this doesn't solve the problem please post back in a Comment.
We will go on to test the various voltages coming out of the Power Supply.

(If a multimeter is not available an economical unit can be purchased. Most auto parts stores carry them, as well as a multitude of other stores. A $5 to $20 unit will do just fine.

The voltages involved are 3.3 Volts, 5 Volts, and 12 Volts.
ALL are DC voltage.

Two D cell flashlight batteries produce 3 Volts DC )

Hi
please check the cable between the computer tower and the monitor.
either the cable is not connected properly or the cable is defective.
this is a message you normally get when the computer is off, and you try turning on the monitor alone.

hope it helps

One possible problem is that a memory card is not seeded properly. To check take all memory cards out and put back one at a time.

To do that touch the metal case of the PC to discharge the static electricity in your body before touching the memory card or mother board. I would do that each time you take out or put in a memory card.

You may get a screen saying your memory has been change. Just hit ok.

If you are not even getting a blinking cursor on your screen the power supply could be bad or some other part is pulling down the power. It that is the case try disconnecting the power jacks from the mother board and reconnecting. They may not be seeded properly.

Also try pulling one card at a time off the mother board and reseeding. You may have to unscrew a screw to pull a board.

Good Luck,

check if the ram if is compatible with the board
check if the battary power the bios

delete and reinstall your email software.

It depends what program you used to add it in the first place. Open the software and look for settings, or just uninstall it.

desktop or laptop. ? external Keyboard or internal

no pc told, Pavilion means zerothat name is is used on desktops and laptops for agesthe HP has diagnostics so run those. HP.com tells how.not told desktop or laptops. just 1 word."Screen"first Pavilion was 1995

HP.COM << go there. And ask a real question ,you did not.

learn to google mate. this is no secret,gee millions sold. A6Y530A the partsurfer shows true model, and fails this is the only post here ever asking for reverse code lookups on models fake, and is not easy in vast cases I guess you have no such PC, (look like) so why ask this>? what prompted this quest>? not told why not ask seller for photos of it if this is a pre sales question , is it>? google and bing and HP all show that model # is BOGUS so go back to your sell and ask the we can not guess PCs ever. HP product ID# is best on the service tag for SURE. where did you see this number, not told. or that number is some 20+ year old COMPAQ PC ,lost in the sands of time, and no google hits. you posted to HP forum, (not real) Hp.com is real

what does not working mean (KBD) dead, or 1 key bad or row. what? symptoms matter most, for sure in a LAPTOP IS IT the word Pavilion is on laptops and desktop, dig? G mean zero , the service tag does not just say "G" sorry. easy peasy lemon squeezy HP.com complex URL no? go there tell them your model # or better the service tag code ! . then magically HP puts you on YOUR service support page and all manuals and all driver before your eyes. amazing no? NO told at all or of a laptop or desktop or what./? you posted ANON so I can't just read other posts by you to learn what PC this is , no I can not. there are over 100 PC called G series, and vast years. some PCs by them G1 to 7 are generations, like HP Pavilion g6-1029tx Notebook. if you can find the service tag the product ID # is what matters most this code includes (real model, version , options and country sold) see this, older PCs by them had this. see that , all matters but do not post SN/ or service codes in public. mine: procuct code (nnnnnnABA#) https://www.pcdied.com/TAG-jive/tag-elite8540w.JPG I will guess it is 17" laptop, here is the mess just that 1 sized once you see this you know that G series means not MUCH> https://search.brave.com/images?q=hp+G+series++pavilion++17%22+G&source=web

old PCs do that, for many reasons. but no PC told at all just HP. 40 years of PCs ,10000 + models nobody can guess ever. but I do have the answer, in pure generic form. did you buy the PC like that used and bad Wifi. ?

1. the wifi card is missing, as was super common 10+ years ago.
2. someone put in the wrong card, not from HP list
3. HP blacklists (bios blocks) none HP cards (wifi)
4. the card needs a driver to work if not it is dead or 1/2 dead.
5. the PC needs 1 more driver to make the wifi buttons all work , all buttons related, if not they are dead or act odd.
6. The OS is infected, no OS told at all, not one clue nor if upgraded the OS, and not vast drivers are wrong or missing, (classic)

Im sure this this is not the free w10 upgrade, if it was that too kills drivers dead, for sure HP told you this unstated PC will not run W10 and has zero support from HP, on w10 AS YOUR SUPPORT PAGE WILL DISCLOSE TO YOU AT HP.COM

today there are many PDF , Viewers not juts Adobe ! google finds them like this. https://www.google.com/search?q=pdf%20viewers

bad news now your bricked it just like miillions did google bios update bricked my PC and cry. why are you here and not at HP.com only they can recover bios. they changed the rules now 10 time. so only they know this, and are pain to deal with. UEFI is the enemy here, new rule and regressive as can be. in fact all new PCs can not be regressed, and some old now they even delete the 20 version of bios there, to force that. not saying they did that to your PC, but keep that in your head on all HP PC. the last bios upgrade stated, no going back. the Cntrl_+B might work , the flashback bios trick\ in your manual if you read it.

nobody can we erase all and reload the OS fresh. did not say you can not try but that 99 out 100 will fail.

100% dead black screen no text or HP SPLASH screen now. The problem is hardware where we buy hardware for free, less than at deity level or a thief. you tell me.... no PC told at all not one tiny clue of 1000s of HP models for 4decades are we to guess models and lie to you? now the GENERIC answer USA PCs only sorry I do not do others. fans dead? no beeps> codes no Caps lock key blink codes. no text errors.? 1: does PC run BIOS pages if huge now shorted old relic battery is removed ,yes bingo 1. 2: is the RTC coin cell dead, ,Bingo 2. a $1 uSD ,USA cost. here. 3: the pre 2010 all have bad CCFL lamps; do this flash light test? https://www.pcdied.com/monitors_and_screens/flash-light-trick.html#flashlighttest if yes, that is a $50 to $100 USD parts repair , labor more. repairs are serial process, as fixing one thing bad ,uncovers the next this is how mans machines work just like that. NO PC told, NO PC told,NO PC told,NO PC told,NO PC told,NO PC told,NO PC told, all I can do is BEG,

hp.com go there tell what PC it is (above is wrong, you truncated it) only full model names and number all work. or use your service tag number.

DEAD ZONE IS THAT A PC GAME OR just means in a quandary. yes, is he answer. wifi zone dead, move closer to the router. bingo. WIFI YOU MEAN, "SPECIFICALLY" not Bluetooth or WWLAN 5G. sure. BLUE, I GUESS YOU MEAN YOUR CABLE MODEM IS BLUE LED GLOWING?, well , there are 100s of routers and modems now, even mixed. to 1. yes if the modem LED show connection is good that means it is. but does not mean he PC is ok , nor the router nor the DNS setting best is, call your ISP if all PCs fails and home if only one fails on wifi the say so and we fix just that one failing PC. or reset the router and modem if all fail.

1. first do the modem , pull the AC power pack from modem
2. replace in a minute or 2,
3. the wait for modem to show all good LED CONDTIONS.
4. THEN DO THE SAME ON THE ROUTER.
5. DO NOT PUSH ANY RESET BUTTONS OR BAD HAPPENS.

The ISP will tell 1-5 and does to every caller. endlessly ISP means internet service provider,
