The desktop PC appeared to die on mrs SJ last night. We rebooted several times and the machine was chugging away happy as can be but with nothing on the monitor, which was scanning for analogue signal then digial signal and back again.

I replaced the digital cable with an analogue cable and still no joy. I pulled the plug for a crash and on reboot saw the bios boot screen with about 20 thin vertical white sripes down the screen but this allowed me to boot into safe mode: cue a grid pattern of small white squares about 1 inch apart from each other.

Vista safe mode finally booted in 4 colours and what looked like 640x480. Updated the driveres (GeForce 7500 LE) and rebooted resulting in the same problem: nothing displayed on the screen.

Bad graphics card? If so then why did safe mode work? If not, could it be something else?

Thanks in advance

Can you borrow one from somebody ?

1. Power supply problems ?
2. Overheating ?
3. Old age ?

P.S. If the hard drive is playing up it might have corrupted the drivers ? ? ? In safe mode Windows uses a simplified basic driver IIRC

Most video cards these days are 2D/3D cards, it can boot quite happily using basic colours, but as soon as you give the go on 3D, it will die.

Things to check.

Can you check if the AGP clock can be turned down? i have a card that wont run at AGP2x, but will run happily at 1x , it used to run at 2x, but died on me after a few years.

Could be a ram chip, try removing them, and just putting one in at a time to see if you gave a duff one.


A replacement card, can be obtained for as little as £30 these days

have you tried cleaning the fan on the card? aother option is to try baking the graphics cards in the oven.

if u have vertical lines flashing or something like 99% its card

Had this a few times, as the guys above say try a m8s card

Once u reboot the card has time to cool but even in safe i bet u saw crap on screen

If you haven't already then remove the card and then re-seat it into the slot on the motherboard.

I had the same a while ago also a Geforce card an 8800GT, worked fine in dos/safe mode and kind of worked in Windows but soon started to play up until there was no display. It was definitely fooked as the replacement fixed the issues. I suspect it to be a faulty chipset.
