My system has runned Windows XP Pro from the beginning. Since a few days, I have updated the system to 7 Ultimate 64bit (new install, not a upgrade).
After I updated the whole system and installed the correct drivers
from Intel and AMD/ATI it ran fine. But after a few hours, I went out for an hour and when I came back, the system had restarted.
The first thing I did was changing the settings so it won't reboot on BSOD. I let it idle for a while and after about 50 minutes, a BSOD occured (IRQ NOT LESS OR EQUAL).
I had it scan the memory for 5 cycles with memtest 86 but no errors found.
Closer look at the dumps indicate that the first BSOD was MEMORY MANAGEMENT and the second IRQ NOT LESS OR EQUAL.
