It usually happens when I try to play games like Skyrim or WoW, and recently it started crashing after about 15 minutes playing Diablo 3. By crashing I mean it just shuts off without warning and to turn the computer back on I need to flip the power switch in the back of my computer off then back on after a minute or two.

When I tried to download minitoolbox it would tell me "Failed - Download Error" Ive tried to download it from multiple sources all with the same failure to download.
Im running Windows 7(64bit). This has happened with a large list of games like Fallout: New Vegas, Elder Scrolls online, Diablo 3, WoW, Heroes of the Storm, Skyrim, Neverwinter Online, Far Cry 3 and 4. Sometimes by turning the settings all to Low and Medium it lets me play for a half hour to an hour, sometimes even longer but then sometimes it will crash after only a few minutes. Theres maybe a couple times where it crashed while I was watching a stream on Twitch as well. Ive cleaned out the computer with compressed air, removed and reapplied my processor chip with new thermal paste, installed a new heat sink as well as an extra fan to see if that would help. I really dont know what could be causing this, any suggestions would be appreciated.
