New video card throw vertical bars on screen

Asus Geforce 9600gt video card
December 23, 2009 at 01:29:32
Specs: Windows XP Home, Athlon64 4000+
My faithful GeForce 7900GS suddenly died over the weekend and I purchased a GeForce 9600GT to replace it. I am fairly sure it's compatible with my motherboard (Asus M2V) and I bought the Asus video card, assuming that an Asus video card on an Asus mainboard would be compatible.

I removed the old drivers and installed the new hardware. I then discovered that the screen was badly distorted and was tearing pre-windows. I loaded XP anyway and discovered vertical banding on the screen. Installing the correct drivers had no effect and I have been unable to resolve the issue.

I would guess this is a hardware fault but I'm not sure

I have screenshots available if they would be useful

Any suggestions would be much appreciated.

was the 9600 used? it does kinda sound like a bad video card...

do you have onboard video for troubleshooting? that'd help test the rest of your machine, removing the video card as a variable. Do you have another machine? it'd be helpful to test the new card in a known good PC.

did your 7900 just die, or was your house struck by lightning or something? I am looking for anything that might suggest hardware OTHER than the video card is bad, like the mobo or PSU.

Thanks for the prompt response. I really am scratching my head here trying to find a cause other than a bad video card. Tech support at Asus have suggested it may be a hardware fault but I'm waiting for them to reply to my e-mail.

The Asus branded 9600 was brand new and unopened. I literally received it from eBuyer yesterday morning and tried installing it last night.

The computer in question is around two and a half years old. I built it before going to university.

The 7900 died very suddenly. One moment I was online in Firefox, the next it was trying to reboot and beeping at me with a blank screen. I did have a power cut a few weeks back, but my machine is plugged into a surge protector and I unplugged it from the wall before the power came back on so that if there was a surge, it wouldn't harm my machine.

When I started trying to work out what was wrong, I took the machine downstairs where I have more space and when I tried to power it up, the CPU fan started to run up and so did the GPU fan. Then there was a very unpleasant burning electrical smell and everything turned itself off. One of the voltage regulators on the 7900 smelt like it had failed.

The power supply is a Hiper 530W Type M. I've built three separate machines with these PSUs and never had any problems before.

Unfortunately, the M2V doesn't have onboard video. I had to borrow a spare 7100GS from a friend to get the machine booted up. With the 7100 installed, it runs absolutely fine, so I assumed the problem was with the 9600. I don't know if my friend will be able to test this 9600 but I can ask.

I do have screenshots of the problem if you would like to see them.

The fact that another card works rules out the motherboard.
"there was a very unpleasant burning electrical smell " doesn't sound good for the card.
I'll take it that you knew enough to connect the proper power connector to the video card if applicable, in which case I would be returning it for replacement.
Seeing it worked initially I suspect a faulty card.

The burning smell came from the original 7900 that I now need to replace.

The 9600 has never worked properly since I fitted it last night and receives all its power through the PCI-E slot since it's the "green" energy efficient version. It was supposed to be the replacement for the dead 7900!

Thanks for ruling out the motherboard. That was one thing I did not want the hassle of changing!
