Well i had some problems with motherboards in past week, my PS3 that i have owned for few years got the yellow light of death. Im pretty smart with electronics and fixing things, looked up what could be done, and i couldnt believe after taking it apart i had to stick the motherboard into the oven at 350 degrees for 10 minutes, who in the world figured that one out is a genious. Well i cleaned out the system of dust, applied some arctic silver on the CPU and it powered on and its actually really quiet now, the fans dont go berserk anymore and its working perfectly. So if you guys ever get that problem, dont send it to Sony for fixing look up on google for some instructions on how you can fix it your self and save some money.
Also just my luck i built a new computer yesterday for gaming, got all the parts from newegg and the motherboard was dead right out of the box. It took me quite some time figuring out what was bad. It turned on but didnt post, i changed out the PSU, ram, and it was just a mess because there is no easy way to figure out whats wrong with it, but new motherboard worked out great just have to return the old one now.
