PLEASE READ ALL SO I DONT HAVE TO RETYPE WHAT I ALREADY SAID
I recently built my computer and everything was running fine the first night im actually using it right now to wright this,but im on my onboard video. i installed quake 4 and still everything was fine my gpu took it fine. So the next day i went out and bought battlefield 2 and installed it and when i tried playing it everything started to get distorted and so i took it out. Now ever since then my graphics card has not been working right please help ill list everything i think is needed. Oh yeah i have downloaded the newest bios for my computer and i have uninstalled and reinstalled the drivers for the card, but it runs slightly better without the drivers. I am also using the newest driver.
My problem i am getting distorted images and pixelation. My computer runs extremely slow when plugged into it. My monitor blinks when plugged into it. I have all power supply plugs into it so its getting enough power.

my specs
GeForce 7800 GT OC
450W ps(only 400W is needed)
Mobo:Intel D945GNT
Chipset:Intel 945G express chipset
Processor: Intel pentium 4 630 3Ghz
Ram: 2GB
Bios Ver.:NT94510J.86A.3943.2006.0707.1405
last Driver used Ver. 91.31
OS windows XP

Please help thanks a lot much appreciated

Given the visual distortion, flicker and major slowdown you describe, and the troubleshooting already attempted by , this looks far more like a hardware or power-delivery fault than a simple driver problem. Artifacts that appear independent of the OS (for example, during POST or in BIOS) point at the GPU or its memory; intermittent improvements with drivers removed point away from a pure software issue. Since recommended testing in another machine, prioritise that — it is the single quickest way to confirm a defective card.

Try this ordered checklist to prove the fault (do one item at a time and document results):

  • Test the card in a known-good PC (or test a known-good card in your PC) to isolate board vs. system.
  • Look for artifacts before Windows loads (BIOS/POST screens). If they appear there, it is almost certainly hardware.
  • Boot with no drivers (Safe Mode or a Live USB) to see whether artifacts persist; use a clean driver removal tool before reinstalling drivers if you still suspect software.
  • Reseat the card, clean the gold contacts with isopropyl alcohol, and verify the PCIe power connector(s) are fully seated and undamaged.
  • Visually inspect the card for swollen capacitors, burns, or cracked solder joints.
  • If possible, measure PSU 12V rail voltages under load (multimeter or PSU tester) or try a different, known-good PSU to eliminate power-rail issues.

If the card shows the same faults in another machine or shows artifacts before any drivers load, prepare for RMA: record a short video showing the problem, list every test you ran, note serial/part numbers, and include photos of connectors and PCB. That documentation speeds up support and reduces back-and-forth.

A few cautions: avoid prolonged stress testing if severe artifacting appears (it can worsen damage), work anti-static-safe, and don’t assume software fixes if hardware signs are present. If tests point to a dead board, push for an exchange/RMA with the vendor and include the test evidence.

I would try to test the video card in another system and/or test the PCI-X slot with another known good video card to start with.

well i called the support and they said i needed to get a new power supply with more amperage on a 12V line so i went and bought it and still nothing i think its dead im gonna call them and get a new one

baaaaaaaaaaadddddd phone support going on 15 min
