A few months ago, you guys help me build a computer for my GF's oldest son Sean(thread here- [WTB][US] Cheap computer ). Well we're having a problem with it. When the computer is turned on, it'll run for 2-3 minutes, then it just shuts down and will not power back on until some time has passed. When it shuts down, I hear a click from the tower. Temps are in the 61-63'c range when shut down occurs(seems the heatsink that was donated isn't adaquate for the quad) and I plan on getting a better heatsink for it this weekend(I'm working now, so I can afford the parts now). So the temps are high, but not so high that they would cause this shut down. Sean tried using it for several weeks before telling me he was having heat problems. System specs of the comp are- AMD Phenom II 965 w/ Cooler Master 752 heatsink ASUS M3A76-CM AM2+/AM2 AMD 760G Micro ATX(using onboard video until I can get him a 5770) 4 gigs(2*2) 1066 Transend Axe RAM Thermaltake TR2 W0379RU 500W ATX 12V v2.2 Power Supply Windows 7 Ultimate 64bit So what do you think is wrong with it?
