[SOLVED] Computer restarts when I launch a game

[PurpDrDerp]

So basically this problem started a few months ago I would launch a game and sometimes my computer would just restart no blue screen no error msgs nothing. Before all this I had overclocked my system. The RAM, CPU, and GPU. It all work just fine and I enjoyed increased performance before all this started. Fast Forward the restarts have become much more frequent. So I watch the CPU temp and its bouncing all over the place. So I assuming its the cooler going bad. I replace the liquid and it seem to work for a day, but I was still having the same issue . After all that I reinstall windows hoping its weird bug and remove all the overclocking that I did. And that brings us to today I ran a Windows memory test and it said It found errors in some of my RAM so I pull out the 2 sticks of 2gb ram and run the test again and all seems normal. and the problem remains. But my CPU temps are no longer jumping up and down its stable at around 35C. So I just have no idea on how to move forward. My computer runs fine at Idle and Im even typing this out on the very same machine. So where do I go from here?

Reset all your overclock. Maybe your PC protects itself from high temperatures. Did you changed FSB ratio?

I ended up flashing the bios too, so that should all be reset to stock

Are you using one cable to power the gpu? If so try to use both pcie cables,means use one (first) connector of each. Test again.
