Installed a q6600 into this yesterday and since that a red light has lit up on the motherboard. The pc works fine its just a bit odd that this has suddenly lit up where before with the pentium d installed only the green light was on. Tried updating to the latest bios and its made no difference. 
Specs are
dvd rom
2900xt
q6600
4 gigs of crucial 1066
500gig hdd
