Answer» I've got problems with a friend's nVidia 8800 GTS. It starts normally for a few minutes, but afterwards the screen freezes and red/blue vertical lines appear on screen. It's not overheating, as it's temperature isn't going over 60°C
We booted the Hiren 15.0 and STARTED the Video Memory Stress Test. It showed about 580 errors on a certain part of memory. I'm guessing that's the error, but I don't know how to fix it :SReplace the card if still under warranty....Are you able to stress test it on a different computer? Some dedicated video cards do share memory with your system (http://www.nvidia.com/page/turbocache.html)
If the card is not under warranty and you have nothing to lose, you might want to try this DIY fix:

Basically it remelts the solder connections and fixes gaps that arise over time. PLEASE EXERCISE WITH CAUTION, THOUGH.Ouch ! !
You sure you want to give that advice ? ?Yeah I did get a stick of 2GB DDR2 RAM working after heating it for 10 min with a Panasonic 1200W hairdryer on full blast. I really doubt a hairdryer can reflow solder, but its still up and working in my Intel rig after 1 month, [email protected] 24/7. No issues. It was under warranty, but I didn't want to pay 7 bucks for a long taxi ride to the STORE where I bought it. Apparently people have used hairdryers to fix laptop graphics cards:http://ask.jaimeyu.com/2009/09/how-to-fix-broken-nvidia-based-laptop.html Search on google and you will find more.
It started failing when I discovered any large file download would always have an incorrect MD5 checksum and that IntelBurnTest would always FAIL within 5 min on Standard(1024MB). I swapped parts out ONE by one until I isolated it to that stick of RAM.
An 8800GTS is a decent card, even by today's standards: http://www.hwcompare.com/5868/geforce-8800-gts-g92-vs-radeon-hd-6770/ Pretty much equal to the Radeon HD 6770.

Yes.No, the card is not under warranty. I'll try swapping RAM modules, and I'm not feeling really comfortable of placing the graphics card into an oven o.O ty for the tip, though

I am familiar with how circuit boards are made, I used to design & have them fabricated. There are several methods for soldering, solder paste & liquid flow bath. In any even, for this procedure, the circuit board is heated to the point where the solder will remelt, around 400 degF. Nothing like using a soldering iron, where the heat is concentrated on 1 spot.
The procedure Transfusion refers to might actually work, but I wouldn't plan on cooking your Thanksgiving turkey in that oven. The vapors may linger for quite a while & the lead will get into the turkey.
Tryptophan + Lead = Dead
