Computer Continues To Crash Even After Format?

About last year my computer started to crash, when playing games. However the crashes were not frequent, rare cases. I didn't bother with it but about 4 months ago, it started to have exe crashes and computer restarts ever so often, maybe an hour or 2 before crashing. I started to look into it, updated my graphics driver, lower the settings on the games, scanned for viruses. Nothing worked, then I downloaded Malware bytes and it detected svchost as a threat. The file is in Windows, instead of Windows\system32. I couldn't really remove this and I got frustrated by nothing fixing this problem so I decided to wipe my computer clean.

When I got back on the crashes continued and not only that, the svchost is still in the Windows folder. And today my computer detected, Trojan: DOS /Alureon, I don't know if that has to do with in relation to the svchost or if my problem is entirely something different. But high memory type of games such as APB reloaded, or the Secret World, cause my computer to crash almost every 5-10 minutes.
