GTX 768 faulty?

[Jumper]

A mate has a GTX 768 meg which has just started playing up and neither of us are sure why? It loads up fine, boots into Vista and will play videos fine and browse fine, games though are different. It'll load the game up and then black screen but the sound of the game can still be heard.

Removing one of the 2 PCI-E six pin adapters enables a few games to be played.

His PSU is a 650W Antec. Would a gpu flash sort this out? he has an Athlon AM2 5200 on as Asrock board, 3 gig ram and a 320 sata HD.

Never came across this issue before. Help much appreciated, other times he says he gets an NV error and it blue-screens. He has had a new PSU and it's made not a scrap of difference, all was great for 6 months.

Thanks. Oh and can you flash a graphics card without a floppy drive? from CD for instance? where would be a good place to get the bios files from. His card is so generic, no marking except NVIDIA with a green swirl on, anyone guess the branding!

You should not flash the card that will not sort the problem anyway.
It looks like it is a 8800gtx card
It could be as simple as a graphics card driver problem.
Try removing the nvidia drivers then use drive cleaner to remove all traces of nvidia drivers.
After that download the latest nvidia drivers and install them.

I have never heard of a gtx768meg card before.
Can you go into the control panel and then to display to find out what card it is.

You never heard of a GTX

First thing i would do is check the temps of the GPU and set up a fan profile to keep it nice and cool, maybe give it a clean if needed (compressed airs good).

Have you tried a new set of drivers?

Does this happen in all games?

sounds like either a driver problem (tell your mate to update to the latest if possible) and if possible try with a known good psu like a 520 corsair or something. im thinking that the psu has been running full blast for six months and is dying. though i have no idea of the amps on 12v rail of his psu. can you find this out for us ?

The power suppli is new, he tried it in another machine and all is well. Overclockers sell the same model, this one:-
