At random times while playing games, my PC will shut off and boot itself up again. The Windows menu where you select Safe Mode or Start Windows Normally pops up. Then the PC boots up normally. This has been going on for a while and happened on and off since I built my PC in January. Please help!!!!

My PC specs are:
Intel Core i7 4770K 3.5 GHz
14 GB of RAM
Windows 7 64 bit
Nvidia GeForce GTX 660
600 Watt Corsair PSU

I can provide any other info needed. PLEASE HELP!!!!!!!!!!!!!!

try gaming again with just 1 brand of ram, its never good to mix and match ram sticks, test it on one brand to see if the problem of restarts is still there, if not youve found your problem.

if the problems still there, you said you only reach 50c, is that on your cpu and gfx? as thats suprisingly low
 
That's the problem, RAMs are never meant to be mix and matched. Only put RAM sticks from the same module or purchase one module and the exact same one later on. They have to the same manufacturer, model, frequency, timing, and even the year of manufacturer can matter from time to time. If you mix and match them, you get a unstable system like right now. Leave only the matching ones in there, if you're not sure, then it's time to invest in some new RAMs.

I was like just what kind of RAM combination makes 14GB??? 2x7??? lol

Is there any solution to this? The thing that sucks about this problem/PC problems in general is it is hard to say what it is cause it could be so many things.


The PC is on a carpet under a desk, but it has room to ventilate.

Also if this info helps: Whenevr I am on my PC I am talking to people on Skype, and sometimes I notice that when I close Skype, it sometimes doesnt crash. I dont think this is the issue, just some extra info.
 
1. I believe you have your PSU's fan facing downward correct? If so, take the PSU out and clean it with compressed air. In addition, do not put a system with PSU fan intake on the bottom on a carpet floor. Carpet is known to contain a lot of dust and dirt that computer does not prefer having. Therefore, clean the PSU, move the PC to a non-carpet floor or table.

2. Are all of your RAM DDR3?

3. Here is a tutorial on Memtest86+, it is what majority people use to test their RAM. Notice that it's a bit old, so the installation process will be different, depending on your situation.

DDR2 doesn't fit in a DDR3 slot, that's a silly question
