Just recently purchased a new LeadTek 6800 GT for my dad (replacing his Radeon 9800 Pro) and after cleaning out all the ATI drivers and installing the 77.72 Nvidia drivers, his computer gets the "blue screen of death" every couple of hours or so. Not real sure what the problem may be, only assuming it's something with the graphics card as his computer ran fine before and now crashes every so often. Maybe try some different drivers? Any help would be appreciated, thanks.

BTW, "MACHINE_CHECK_EXCEPTION" is the error it states on the blue screen.
 
What power supply does he have?

it could be not all ATi drivers are gone - personally i do a complete fresh format when changing video cards.
 
His power supply is fairly new as well, I know it's a 500W so shouldn't be any issues with power there.

He also used a driver cleaner tool that's supposed to erase all tracks of drivers from the computer. Will look more into these though, but doing more research on this it appears to more than likely be a hardware related issue. Could this be the 2nd bad graphics card that NewEgg has sent me? (Originally ordered one of the refurbished LeadTek 6800 GT's, but it booted up with scrambled graphics and such and had to send it right back, of course they didn't have any more refurb's so I was forced to fork up some more cash and buy a new one).
 
a good 500 watter? or jsut a no name 500watter.. is it overheating? hows the airflow?
 
What's the specs on the system?
Some have trouble with Fastwrites or sideband.
Try disabling in the bios and NV Control panel

This is what MS has to say:

Machine check exceptions are frequently caused by one of the following conditions: • You are running the processor or mainboard beyond its specifications. For example, you are overclocking the processor or bus. We recommend that you run your hardware at the manufacturer-rated speeds.
• Noisy power, overstressed power strips, outmatched power supplies and failing power supplies can destabilize your computer. Make sure that you have a stable, reliable power supply to your computer.
• Extreme thermal conditions caused by the failure of cooling devices such as fans may damage your computer. Make sure that your cooling devices are all working.
• You have damaged memory or memory that is not the correct type for your computer. If you recently changed the memory configuration, revert to the previous configuration to determine what is wrong. Make sure that you are using the correct memory for your computer.
Note Your hardware may support additional error logging features that capture the machine check exception and suggest a more specific solution.

The Pentium and Pentium Pro processors provide a mechanism to detect and to report hardware-related problems such as memory parity errors and cache errors. To signal a hardware error, the processor signals the detection of a machine check error by generating a machine check exception (Interrupt 18). Windows XP reports that the error occurred and displays parameters that you can use to decode the exception. Contact your hardware vendor or processor manufacturer for information about the Machine Check Architecture, or see the Intel Pentium Pro Family Developer's Manual - Volume 3: Operating System Writer's Manual.


Try to google Machine check exceptions/ lots of stuff

Hope it helps
 
as said just cause it says 500w doesnt mean it ahs stable solid rails - which is what matter - never buy a PSU simple because it say

Hey look at me i got 500000W!!!!! cause chances are a good 350W fortron would bet the crap out of most no name 500w PSUs
 
I don't mean to dig up an old topic, but just wanted to post the solution to the problem incase any one else may be having similar problems. It turns out that you guys were right, after swapping out the no-name 500w power supply all has been well. Thanks again for the advice guys!
