Question about Computers & Internet

Open Question

I have a HP Compaq A6437c and when i try to power on the unit the lights and you can hear the HD start up but nothing on the monitor. I have tried a different PSU, i have taken out the RAM, tried a different video card and nothing. There is no beeps and no video. Even when I took the RAM out it should beep and nothing. Any advise would be greatly appreciated. The MoBo is a Foxconn MCP73M02H1 Motherboard.

SOURCE: Evo d310 memory problems?

Depending on your boards type beep codes, one short, then 2 short beeps normally indicates a check sum error. This is when your board does'nt like the speed/size or make of your memory. Removing the battery probably hasn't cleared your cmos,look for JBAT1 terminal on your motherboard and place the jumper over pins 2-3 for a few seconds and then back to 1-2. Try to boot again with your original memory. With some boards you have to have equal amounts of memory in the slots (e.g 2 x 256mb or 2 x 128mb) and some memory may not be compatible with your board. If you get up and running go to this site to check memory upgrade options.http://www.crucial.com/uk/store/listmfgr.asp?cat=RAM

SOURCE: ASUS P4SP-MX motherboard no POST and no beep without ram

Try removing everything attached to it. The only thing should be the cpu and cpu fan. Turn it on. If it is the same, then it is your motherboard. If you do get the beeping, then start installing things one by one starting with the memory.

If your power supply is not plugged into a surge protector, you may be having issues with your line causing your power supply to fail. Do you get any beeps? The bios typically will beep to give you an indication of what is going on?

SOURCE: eMachine stopped displaying video (card not working, just mobo)

Hi there

I would say it's the graphics card that's failed. You might get the same beeps for faulty card as removed card....

Take it to a shop where they can test a compatible card, before they sell you one or install one for you.

SOURCE: HP pavillion a800n pc wont' boot up..I get nothing...

After much trial-and-error, I finally figured out the solution for this common issue with certain HP Pavillion models. It turns out to be a design flaw with the front-panel memory card reader. Somehow the card reader's firmware gets scrambled, and it prevents the computer from booting. You can test this on your machine by temporarily disconnecting the card reader cable at the motherboard header. Voila - I'll bet you $1 that your computer will now boot!

The solution is buried deep inside this HP tech support document. The card reader firmware needs to be reset.

Here\'s how to fix it once and for all:

1) With the computer power unplugged (duh), open up the case & disconnect the card reader cable at the card reader itself - NOT the end that connects to the motherboard header. Make sure the cable end is not touching any metal components before proceeding to step 2 (another duh).

2) With the cable still disconnected, fire up the computer. The tech support doc says to let it boot into Windows and stay there for about 5 minutes.

3) Shut the computer down and reconnect the cable to the card reader.

4) Turn your computer back on - your memory card reader will work and, most importantly, the computer will no longer hang at POST!

I suspect that when you fire up the computer without the cable connected, the card reader is designed to reset its firmware by grounding out through the case - sort of like a CMOS Reset jumper on a motherboard.

I hope this solution is helpful to others.

best,
JohnB

My compaq presarion won't start up and the led in the charger hole won't light on


Try removing the battery and only using AC power. If the power
LED on the power brick does not come on then replace the power supply. If it works with just AC then replace the battery. If it still doesn't work, warranty replace the computer.

Computer has power, hear the fan and HD trying to run however nothing happens, blank screen. Plugged in external monitor and still black screen


HP laptops have several problems with GPU overheating. Could also be a bad stick of RAM or a bad hard drive. You will need to remove each one and try to power on after each is removed. If still wont light up the screen you probably have a motherboard problem with the video chip (AKA: GPU processor)

Power up the external monitor first and then boot up the laptop, the video info will automatically divert to the external monitor.
If you do not see a Windows image on the external monitor then it is definitely a motherboard issue, because the video card is built in on the motherboard.
The Video card uses shared RAM (part of the RAM module/s ), try re-seating the RAM modules, also test the RAM modules.
You can test the hard drive by removing the hard drive and connecting it to an USB hard drive adapter, then connect the adapter into a working computer's USB port. If the hard drive is OK, this computer will see it as an external storage device and you can open the various folders and files on the hard drive.

Actually it boots, just that you don't see it. Try using another monitor - even a tv will do: disconnect the present monitor, connect the new one and reboot. If you get an image then the monitor is dead, replace it. If you don't then the onboard video card id dead, get a new one and try again. If even now it.s dead then you need a new motherboard.
