many thanks for the response.
I rolled back drivers it worked temporarily. Then windows updated automatically. I rolled back the drivers and it continues to give me the BSOD
Here is the message on the blue screen:
*** Hardware Malfunction
Call your hardware vendor for support
NMI: Parity Check/Memory Parity Error
*** The system has halted ***
Everything seems to work ok in Safe Mode. I will try the clean boot to determine the problem.
However, i have ordered a new Quadro graphics card as i need a faster card, and will install it and see what happens.
I was able to determine that it crashed whenever I right clicked on the desktop to change the background or use the gadgets. Anything graphics intensive, i guess.
i will post my results. Fingers crossed.
