Well I tidied up the cables a bit and it started happening again. I turn it on the fan for the psu comes on, the fan for the cpu comes on, the fan for the gpu comes on and the power light on the power button comes on BUT this time I noticed something else: The harddrive indicator and the dvd power light would both come on for about 3-5 seconds and both go off afterwards usually the dvd first then a second or two later, the HDD indicator. Anyone know whats causing this?
