Posted earlier about some internet problems here: http://www.tomshardware.com/forum/41383-42-variable-dow...
Still kinda having those issues, but I bring it up because about 4 hours ago (11pm-ish) I finshed putting a Cooler Master 212 Plus on my Core i5 (super recommend it, but it's a pain to get on). Anyway, finsh plugging in wires and what not, test fire it up and both fans on it are working and everything. Turn it off, hook everything back up to it and turn it on, and it turns on for a few minutes and then blue screens. Try booting it again, get into windows, and it immediately crashes. I'm having heart attacks at this point but try booting for a 3rd time. Get into windows and cpu temps are much lower over the stock heat sink, everything is fine...except it's not recognizing one of the 4GB sticks. So I turn it off, fiddle with the sticks, boot up again. This time the mobo sends me to the BIOS because it doesn't recognize any SATA drives (I have 2). Reboot and get into windows now and finally everything is ok (except for the internet problems mentioned above).
I don't even know where to start looking for a problem like this. I was thinking it was a virus or something but I've been doing countless scanning recently and this is only started happening since I've put this new heat sink on my CPU. Honestly my only idea is that bits of the mobo are cracked from the brackets (even though I made sure I didn't overtighten the screws). I'm hoping you guys have some ideas because like I said, I'm stumped.
Main system specs in case it helps:
Lynnfield Core i5
ASUS P7H57D-V EVO
8GB G.SKILL DDR3-1600
Sapphire Radeon HD 6950
