Hi, I've recently installed a 512mb Geforce 7600 GS vid card, and have had nothing but troubles....

i'm running amd 64 4000 on an msi k8n neo4 mboard

my problem being when i install the video card drivers all seems to be ok, but then the screen becomes covered in sketchy lines(kinda hard to explain what i mean) so i've attached a pic of my desktop...

i've gone through all of the basic steps, reinstalling drivers, updating drivers tryin beta drivers to no avail...it all creates the same prob..

one other question, i'm running a 400w psu should this be increased to 450w.......

any help is much appreciated!! Thanks in advance

A compact troubleshooting guide that builds on ’s report and the suggestions from and . The visible line-type artifacts usually stem from one of four areas: GPU/VRAM failure, overheating, power delivery problems, or driver/OS corruption — see the general causes of graphics artifacts for background .

Checklist to narrow the root cause (keep notes/photos for RMA if needed):

  • Confirm when the artifact appears: if it is visible in BIOS/POST screens or on a different OS (try a Linux live USB), hardware fault is extremely likely; if only after Windows loads, drivers or the OS are suspect. This echoes ’s safe-mode/monitor suggestions but extends the isolation to BIOS and a separate OS.
  • Do a clean driver purge (use a driver-clean tool) and install a known stable WHQL driver rather than betas. If artifacts persist after clean installs, move on to hardware checks.
  • Swap parts: test the 7600 GS in another working PC, and test a known-good card in the original system. Cross-testing isolates motherboard/PSU vs card.
  • Physical inspection: look for bulging/leaking capacitors, burned traces, or a non-spinning fan; reseat the card and try a different PCIe slot if available.
  • Power checks: verify that the PSU can supply stable +12V current and that any required PCIe auxiliary connector is present and plugged in. Wattage alone is not the full story; rail amperage and PSU quality matter Power supply unit (computer).

If hardware is confirmed, document artifacts (photos/video), record the serial/date, contact the card maker/retailer for RMA, and avoid risky fixes (reflow) unless out of warranty and experienced. ’s warning about progressive failure is valid: early action preserves return options.

I am not an expert, but I know a little about video cards because I love gaming. I would try to use resolution 800X600, and then set refresh rate at lowest setting, be sure to click on the option that reads, "Hide modes that this monitor can not display." If that does not work, try setting at each refresh rate to see if it will fix the problem.
Does this happen in safe mode? Do you have another monitor to try and see if it does it on both monitors?

THIS IS A HARDWARE FAILURE!

this happened to me very recently with my geforce 7800 gt.

i'm sorry to say no drivers will help as this is a hardware problem!!!

you will need to send the item back to who ever you bought it from and have it repaired or better replaced, and do it ASAP! as it will just get worse!

trust me if you leave it too long it will start to happen when you try to boot up and prevent you from booting up at all.

i ended up buying a new card to keep me going while i wait for mine to be sorted (mine is outside the 1 year suppliers warrenty) i'm still waiting to hear from the manufacturer!!!

dont leave it, get it sorted!!!

hope this helps
