So I bought this PC pre built and it worked great for a few months but then during some specific games like Counter Strike Global it would randomly restart. I thought it was overheating so I monitored the temps and the CPU and GPU were getting a little toasty. I decided to replace the gpu and under clock the cpu I did so and no more overheating but it still kept restarting here is my computer.http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=9095523&Sku=

and here is my new graphics card. http://www.newegg.com/Product/Product.aspx?Item=N82E16814125684&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-PCPartPicker,%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=

when my computer starts up it also makes a sort of grinding sound and I dont know if that has to do with anything. And also since yesterday if I dont power down my computer by holding down the power button for 5 sec and I turn it off through the windows start menu by clicking shut down, when it turn back on it will do everything normally and then the monitor will go unresponsive as well as the keyboard and mouse, also dont know if any of that is related.

Please guys I really need some help some of my favorite games are coming out and i cant have my pc crashing during them. I contacted cyberpower technical support and didnt help at all. I regularly play league of legends and it has only crashed during that game 3 times.

What 600W psu does that PC has? Open up the side panel and post a picture of the label, knowing what motherboard does it have also helps. Also post what temps are you getting to make sure, if you underclocked the CPU due to overheating you just fixed the tip of the icerberg, you need to fix the source of the problem.

Hey thanks so much for the reply here is a picture of my comp power supply and mobo, and the temps that I got when it last shut off were around high 60c like 68-69 for the gpu and around 49-50c for the cpu. when before I underclocked I was getting around 58-60 for the cpu when it shut off, thanks.
