Recently bought myself a new rig of the following:
Asus Maximus ii Formula (ROG)
Intel Core2 Quad Core Q9650
2x2gb Corsair Dominator 8500
XFX GeForce 8800 (GTS i think not sure though)
Corsair HX750w Modular PSU
Seagate 500GB Barracuda ES.2 32mb cache
Built it all up and installed XP on it, was being troublesome as it randomly BSOD a couple of times during install and when restarting (too quick to catch the error code). I figured with my copy of XP being SP1a it was just too old so I forked out and got a new copy of Vista. Seemingly in the nick of time as then Vista failed to boot ("Windows did not start correctly, safe mode etc", then it would BSOD every time).
Installing Vista: Boot from CD (I wiped XP off the HDD so it was fresh install), loads the files, gets to the green scroll bar just before it boots the installer and this BSOD pops up:
"DRIVER_IRQL_NOT_LESS_OR_EQUAL" - Removed one of the sticks of RAM and this allowed me to get to actually installing vista. At around 7% when it's "Expanding files" the same thing happens.
When I try to reboot and start the Vista install again, it then BSODs with "BAD_SYS_CONFIG" or something similar. I then have to format the HDD (by putting the XP disk in and going to the repair console) and try this again.
I suspect the RAM is the problem as i've tried a different GPU and the PSU should be more than ample, but I don't have a lot of experience building Core2 systems so any advice and help would be greatly appreciated.
Cheers!
