Hey guys...been trying to wrap my head around something for a while but no luck.
I have a Dell Inspiron 9300 which originally had the NVIDIA GeForce 6800 graphics card. A little while ago it failed on me. Since I dont game much anymore, I decided to just buy a used working pull ATI Radeon X300 from ebay. Plugged it in and installed the latest drivers from Dell website and everything worked fine. PC boots fine and resolutions is as its supposed to be. However, everytime I now use the pc, around 30-40 minutes into using it (e-mail, browsing, normal stuff) the screen freezes on me. Everything gets stuck and just the power light and the HDD light remain on constantly. I cannot do anything except for hard shutdown by keeping power button pressed.
Below is what I tried:
1) Uninstalling previous NVIDIA drivers and reinstalling ATI X300 drivers (latest ones from ATI website. Also tried the driver from Dell website). Did not solve.
2) Full format and fresh install of windows. Tried windows XP that came with the system and also tried Windows 7 Home Premium. Did not solve.
3) I have currently disabled the graphics adapter and will see if it still freezes. Maybe it is overheating. However, I dont see that happening as my previous card (NVIDIA GeForce 6800 was more demanding than this little guy...i stepped down!) I will post if disabling graphics card solves this issue or not...which will isolate my problem to the graphics card only.
Also, when I put in this ATI X300 card, along with the new drivers, do I need to update BIOS as well? I did download the ATI BIOS that pops up on Dells website. Is there anything else I need to do BIOS wise?
I also opened up the pc again and made sure my fans are not jammed or the video card was not installed properly. Everything seems to be fine. I also took out and put back in the RAM cards incase there was static build up or soemthing like that (read about that as a possible cause on some forums so tried it.) No luck.
Was also reading that it could possibly be the capacitors or the PCU. Which capacitors are these? on the motherboard? My mother board was changed by Dell 1.5 years ago so dont think that the capacitors went faulty already...who knows.. Not too sure about PCU as the replacement card was the stock card that was an option while configuring Dell 9300 as well.
Do you think the motherboard I have is specific for the NVIDIA GeForce card and not the ATI X300 and thats why this issue is popping up?
Any help will be appreciated! Stuck here!
