For the past 3 months my PC has been mysteriously shutting down (turning off) in the middle of use, after boot, & at non repeating intervals. I replaced the PS... still failing. Today I analyzed using RealTemp & Fan downloads to see I was running way to hot. Cores running over 100 degrees regularly. System Snapshot: Win7 Ultimate Intel Core2 Quad CPU Q6600 @ 2.40GHz 4.0GB RAM NVidia GeForce 8800 GTS Case: Armor 4 fan tower as pictured This was a custom build from a work friend & FAR too powerful for the internet/email/excel & word work that I do. I made the problem worse when thinking the shutdown problem was PS related, I put in a new one & had to disconnect the top fan to fit the new PS. But this is not root cause as the problem existed prior to this mistake of mine. Now: What to do? I have a Vornado from Target (pictured) shooting into the open side of my PC (temps under full load now high 80s!) & I just completed the same test (a virus scan) that caused shut down before, confirming that HEAT is indeed the problem. That is great news for me to know the problem. Im looking to some experts out there to help me identify a good solution. Please recommend specific set ups & products. Thanks for ANY help.
