My home computer was out of commission for quite some time, since April, in fact. I bought a new PSU (750 Watt) and new 24-pin motherboard that supports the CPU I chose. It supports my Q6600 and RAM modules and everything is plugged in correctly. However when I boot up, my system lights flash on and the fans all spin for half a second and then everything stops. Any further attempts to power on the system doesn't even cause the lights or fans to power on for a split second, which I assume is my motherboard or PSU preventing me from frying my system by cutting off power entirely (I read about this feature somewhere in one of the manuals for the PSU or mobo). My computer does not make any beeps of any form. Essentially, I am unable to get to POST. I have tried several other power supplies and none of them work. I was told by a teacher a few years ago that some computer parts deteriorate over time if they're not used and I'm wondering if this is just a wives tale of the PC world or if it's legitimate. Do you guys think it's the RAM or CPU that's not working? I have tried other motherboards as well so I don't think the PSU or mobo are defective.
