No display?

post #1 of 8
Thread Starter 
Hello, I have recently received my friends old desktop as an early Christmas present. The only problem is that I get no display when I turn it on, the monitor simply gives me the error saying that it is not receiving a signal and turns off. In an attempt to pin point the problem I striped the computer down to a processor, mobo, the case and processor fan, a single RAM chip, and the Power supply. When I started it up there was still no display, I then re installed everything back into it. There is no smoke, beeping, whining, visible burn marks on the mobo or anything of that nature, it has 2x 1gb ddr2 ram installed, an amd processor, 1 WD HDD, 1 Samsung HDD, a DVD-RW drive, a wireless PCI card and then the ATX power supple and mobo. From what I have deducted, I believe the on board VGA port has died. I would greatly apprecaite any ones advice on the matter, I also have no video card to give me an extra VGA output to test my theory.

It could be the input on the monitor. Happened to an old monitor of mine. Unfortunately, that display only had the one input, so it ended up in the trash. You could be looking for some sort of tutorial on fixing it if this is the case.

If you live close to your friend,you can try going to his place and try the monitor there. I am assuming that you have video card already in your computer.

Can you go into the monitor setup menu?

Check the CPU, if there's a bent pin or not enough contact ( if you get thermal paste in the socket or pins ) you'll often not get a display working.

It could also be a bad BiOS.

@brfield: I have tried 2 different monitors that I know work and i have also tried a few different VGA cords that I know work, I apologize for not originally mentioning that.

@Fishinfan: I have not tried going into the monitor setup menu, but as I stated above I have tried different monitors which I know work. Also I am using the on-board video, if I had a video card to plug into the mobo I would try using the output from that but sadly I do not.

@Shrak: I have checked the CPU and as far as I can see all the pins are fine and there doesn't seem to be any thermal paste anywhere besides on the top. However if it does happen to be a bad BIOS, how would I go about fixing that without a display?

If it is a bad BIOS you can often buy new BIOS chips from the manufacturer. They're pretty cheap ( usually $5-15 or so ).

Actually had my Asus Sabertooth P67 get a corrupt BIOS from updating ( although the situation was weird and it said it was successful, but apparently it wasn't ). Computer would turn on, but no post, and no video signal at all, called up Asus and they said the update likely failed and a new BIOS chip would help, which it did as it's working great now.

Usually they are replaceable as long as they aren't soldered to the board. If you can't figure it out with any other solution and want to at least try the BIOS chip you'll have to look for it to see if it is replaceable which will look like one of these;



Which pulls out like;



or



which pulls out like;



But I would save that for last resort, just to save money in case it doesn't help, or if you find another solution to the specific problem.

Thank you Shrak, I will definitely look on the mobo to see if I can't find it and if it is soldered on the board to prepare in case I do have to resort to that. I am going to contact another friend of mine who should have a Video Card I can borrow to test my theory and I will re-post with an update as to if it solved my problem. Thank you again for the advice and directions on replacing the BIOS Chip. +rep

If you haven't done a bios upgrade then it vs unlikely is a bios chip, but not impossible. It could be a faulty VGA out on the board, or its possible your power supply nuked the board. Does your board have another output you cab try? And without anything plugged in bit CPU and RAM will it post? Use a case speaker to diagnose.
