Whenever i go to play a game specifically smite my computer will restart, shut down, or it will go to a light blue screen along with this buzzing sound from the speakers, which i then force shut my computer off. I did a system restore to when i didn't have a problem, but it didn't work. I rolled back my GPU drivers that didnt work. I was using Malwarebytes and Microsoft security essentials, and i would run scans regularly, and nothing would come up. i just recently got a new security software, and ran a full system scan and a Trojan was detected. Could that be the problem?

I built my computer around November, and it has been running perfectly up until a couple of days ago.

Specs:
Nvidia Geforce gtx650 ti boost GPU
i-5 3350p CPU
cx 750m PSU
Motherboard: Gigabyte z77x-UD3H
Windows 7 - 64 bit home premium

i appreciate any help thanks!

2 things. Firstly check for cpu tempratures. If it goes over 99C pc automatically restarts.
2nd, Since you say light blue screen, and trojans etc... do a format, it wont hurt.
If u have no issues with tempratures do a format 100%.

I havent cleaned it since I made the system, so do you think i just need to clean it? I dont think it is an overheating issue because i have 7 140mm fans in my case.

7 fans to me means 7 times more dust build up. Grab a cheap can of compressed air and go at it but be careful with the power supply. They can be dangerous. Also make sure you hold the can upright and that the computers off while cleaning. If any of the liquid from the can hits the pc while its on, you can have a problem. Also, my cousin had a pc back when the 6870 was new and it kept rebooting while playing games. turns out all he had to do was change the outlet. idk if it was faulty or too many things had been plugged in but its still stable to this day.
