20 Most Recent E-Machines (308714) Motherboard - Page 5 Questions & Answers

According to the internet, your computer has an Intel 845GV chipset motherboard. Intel tends to use a generic pattern for connecting the front panel connectors. A description can be found on intel's site.
If this doesn't solve your problem, comment back with the motherboard model number. Look on the board, it should be printed somewhere, and it should start with D845GV...something something...

if you cannot access the bios at all even after a cmos clear, then bios chip is damaged, unless you can and are able fit another one you will have to replace the motherboard

Hi the 3 wire connector you have mentioned is for the FAN do not forget to connect it - you can find a 3 pin connector either white / brown in color on the motherboard - plug the 3 pin connector into this - it can be connected in only one direction .

Hallo Babados,


If you already have a NEW POWER SUPPLY, I would get another MoBo and install it carefully. You can fire up the new MoBo out of the case with the processor and RAM just to see if it comes on. If it does, then install it.

Also Barbados, MoBos don't burn suddenly. It is usually power shorts or mishaps that burn MoBos, so you want to be careful with your power source. If you have a UPS, use it as you work with your PC.

Good luck, Barb!

you have to be sure about power check outlets power and power supply with power supply tester you can get that on any computer store i get mines from fry'z electronics after you check that probably not have to do any other test to me is the power supply if any of the out lines from power supply is bad you can have that problem the out lines have 12v 5v 3.3v and 3v so check that

well that is 17,000 volts there 17kv and can be lethal . CRT is cathode ray tube and 2nd anode is 17kv, 1kv per inch screen.. we use a chicken stick to discharge that. one guy gut hit here and flew across the room ,hit head and next up paramedics deep.. not fun to see that. ive taking 600v but never again. vaccum seal, why do that.??? send it to the , toxic lead recycle center, let them do the danger work when I was only 16yo I worked in TV shop and I had do that "nnipp" that in the bud on all CRT sent off to refurb. (or toxic trash) (we sold them all here, you name it) we had to remove the socket there find he glass bud there dead center and full PPE, and snap it with wire cutters and it sucks in air fast. later in military too on old radar scopes, i worked . the vacuum inside is pure and prefect, zero gasses. implosion hazard exists. a glass flies in the bounces out and hits you and then next up blind i one eye. leave CRT alone to the trained.

the monitor is dead. PSU dead inside. only used PSU sold on ebay.

to boot a cd then you must have the bios set to allow it, or tap f12 immediately to intercept boot menu and choose cd. sounds like your drive has a few bad disk sectors.

firstly lets think why a Working pc would no longer BOOT. The boot process then. a pc starts the bios which POST's. this results in ONE BEEP which might be followed by messages(if you get several beeps then they are like morse code long/short and count out an error code). when you get your ONE BEEP the pc is working. when it then HANGS(appears to do nothing) its usually because of either a) the cd drive is duff so disconnect its cables. b) the hard drive is duff so disconnect its cables c) the hard drive hasnt quite died yet but has some very slow sectors and is making the Clackety Clack of the heads recalibrating every few seconds. d) there could be a a gpu card bios glitch and your pc is running but you just have a blank screen. some hints then 1) never start removing parts as that corrupts the CMOS(the battery backed up configuration for your BIOS) so you may need to clear your cmos. 2) never play with the idea of changing ram sticks as people usually end up putting them in any old slot(which may result in a non working pc). make sure a PAIR is fitted in slots 0/2 and a separate matching pair in 1/3 slots not in slots 0/1 which is two half pairs. Other factors. 1) a short circuit. your PSU has built in protection, if the psu fan(inside case of the psu) turns and kicks back and immediately stops you have a short circuit and its cuts the power to avoid a fire/meltdown, which could be caused by high wattage gpu(>60 watts) without its extra power cables fitted or wrongly connected front usb cables or removing a mainboard and fitting it into a new box where the board has its support posts NOT lined up with the holes fro the screws so the post is touching underside of the board circuits. hope some of that helps.

Download a Linux distro to a flash drive or DVD and see how well it runs off that. There's HDD utilities like SuperGrubDisk that can diagnose things.

Unfortunately, without a specific model number for your monitor, this may vary from the manual I am referencing. Just the same, I should say the link should at least have enough similarities to get you out of a scenario mode, and into the custom configurations (that I am assuming you are after). The steps begin on the bottom of page 5. http://global-download.gateway.com/GDFiles/Document/User%20Manual/User%20Manual_Acer_1.0_A_A.zip?acerid=634321354437313817&Step1=MONITOR&Step2=FLAT%20PANEL&Step3=E182HL&OS=ALL&LC=en&BC=EMACHINES&SC=PA_6E If you are using a similar model, clicking on the menu button will bring you in the OSD menu where you can customize the brightness, contrast, etc. Any changes will become a "custom" mode that will effectively take you out of anyone of the scenario modes. I have seen monitors that do not allow much customization (if any) outside of the scenario modes. You may find specifics if you search the monitor model number itself. If you post that information in the comments I can help you find info more specific to your display.

Knowing the beep pattern will help diagnose the issue. Power on the computer again and listen for long beeps and/or short beeps. There are other possibilities, but if you just cleaned out the computer, I suspect you might have dislodged a memory stick. Make sure they are seated completely and the white tabs are locked securely in place. The beep code you hear will ultimately help determine where the failure is happening.

try booting to safe mode. by using f8if that works, try a system restore to a previous date. if that does not help, then it must be a windows corruption and parallel install or repair install will be needed, it can also be fixed by manual troubleshooting and repairing the files.
