Trouble Running Games...!

[Thumpp]

Hey, I was wondering if someone could help me. I've recent installed a new motherboard into my PC and since then I've been have some problems. A lot of times when I got to play games like battlefield 3 or Arma 2, I only get to play for 15-20 minutes before it locks up and gives me the Windows error box. Occasionally I even get blue screened for memory management and only things, I have no idea what is wrong, I've uninstalled and reinstalled all of my drives and I still get this problem. Help please!

when you install motherboard... did you clean install os? (or just update?)

you need to post more details about your computer...

I just kept the old OS and I have - Sabertooth Z77 motherboard, Core i7 2600S CPU, MSI H6870 Hawk 1GB GPU and my Windows 8 64-bit is on my Samsung 830 series SSD

You're missing power supply and case - the PSU is important in issues like this, and the case helps determine if your machine is undercooled. Also that's a strange setup - a Sabertooth motherboard with a low-voltage CPU?

For now I suggest running stress tests and see if you can reproduce the problem, I'd start with a GPU stress test but you should do CPU as well:
Overclocking tools of the trade

For the GPU stress test, get MSI Kombustor from the link above, run for at least 1 hour and monitor your temperatures.
For the CPU stress test, IIRC you can get a utility from Asus to monitor temperatures, then run LinX for at least 1 hour and monitor the temperatures.
