I have to say, at first blush, it sounds like a corrupted installation of Windows. The solution there would be to either run a repair, or to reinstall a fresh copy of your operating system. It could be simply software corruption, but don't rule out a hard drive on the fritz, or getting ready to die on you. Before you do much of anything, try to get a backup. If you have access to another computer, you can yank the hard drive from the non-functioning one and use [http://www.amazon.com//dp/B00DQJME7Y/|one of these] to plug in the hard drive and pull important data off before you delve into the world of troubleshooting. When diagnosing issues that force the system to restart without any warning, your best bet is to start removing extraneous components and working backwards until you figure out what *does* work in a minimum system build. Remember MVP: Minimum Viable Product. This can be time consuming, and I'd be remiss if I didn't mention that [http://store.pcdservicecenter.com/|there are kits available] to thoroughly test the hardware if you have the money and time is at a premium. If you'd rather invest the time, then start by removing the big offenders. Strip the system down to a single stick of RAM. Remove the video card. Disconnect the hard drive, and try to boot to external media (or a Linux Live build on CD/DVD/USB). Try to get the system to run for a period of time (or even stress, if possible) in order to reassure you that there aren't any hardware-related issues that need to be addressed. If you still fail with a single stick of RAM, try swapping that stick for one of the others you pulled out--you may just have stumbled onto the bad one.
