ok I have an ASPIRE X-QPACK-AL/420 w/ BIOSTAR TForce6100 Socket 754 NVIDIA GeForce 6100 Micro ATX AMD Motherboard , AMD Sempron 64 2600+ Palermo 1600MHz HT 128KB L2 Cache Socket 754 i recently bought a XFX PVT42GUAD7 Geforce 6800GS 256MB 256-bit GDDR3 PCI Express x16 from a friend that i know worked perfect in his pc.worked fine for a few minutes then i would get blue squiggles across screen and finally monitor would shut down like it was getting no signal. reboot and get same results. any opinions?
thanx
 
Simplest way to troubleshoot this situation is to eliminate certain variables. I reccomend you re-test the video card in another computer that you are confident has adequate power.

If the card works fine, it's easy to eliminate it as the source of the problem. If it does not work, well, you get the idea.
 
Also might want to pull power on anything you can and try to reproduce the failure (in case you don't have another system to work with). Sounds to me like a cooling issue on the VGA card tho. Seems odd to me tho, since your case generally has excellent cooling properties, and it was working fine for your friend.
 
Usually weird artifacts on your monitor means either video card is overheating or it's kicking the bucket. Happened to a friend of mine recently.
 
I monitored the temp while it was acting weird and it stayed low the whole time.
 
Yeap, test the video card on a different PC is the best way to narrowing the problem. Maybe something happened during you taking out the card from your friend's system or during the transit to your system. (That's if the video card is now bad). If not, maybe you forgot to plug in a cable here or there.
