I have searched online and found a problem similar to mine where people said the power supply was too weak and I wondered if that was the case with me. I have a 450W PSU from an unknown company and i read that cheaper PSU could have smaller wattage than advertised. Anyways...
My computer doesn't "exactly" shut down. I hear a fan speed up and the screen goes black, as if the video card had shut down, and it only happens when I'm playing games, not when I'm on the web or something like that, and it isn't slow either. And when it "shuts down" I have to manually restart it and everything stops functioning, only skype or youtube will work for like 1 minute more but nothing else. I think it might be because the CPU might use a little bit too much of power. Like I can play CS 1.6 fine, but when I started skype'ing with my friend it crashed my computer after a few minutes. Ask me if you need anymore information, cause I can't think of anything from the top of my head right now. And could you tell me if it is a PSU problem then what kind of a PSU would I need. And here Are my specs. :
Intel Core i5-600 Quad Core 3.33
Sapphire HD7770 Ghz Edition 1GB
4GB Ram 4x1GB
Motherboard form Gigabyte GA-P55-UD3L
2 SATA HDD's which probably consume more power than 1 HDD
1 DVD RW Drive
I also have atleast 5 USB devices constantly connected to my PC. One of them is for speakers and one for headphones. Also have a printer, controlers, keyboard and mouse.
And Big thanks to anyone willing to help and read my tremendously long post.
*A COUPLE OF WEIRD UPDATES*
*It's not a No-Name its Codegen
*I got it working for a day by removing and putting back the bios battery
*It's crafshing while I'm using Chrome
 
My first guess would be the no-name PSU. A high quality PSU is the most important component if you want a stable system. I would replace the PSU with a tier one or tier two PSU from this list:

The problem could also be related to overheating. Have you monitored the CPU and GPU load temps? You can use software like HWMonitor to monitor the temps.

It's not overheating but it used to because I was running it with the sidepanel off for a while and it gathered a lot of dust, though I have cleaned it. And found out it's not a No-Name but a Codegen 400X(PFC) 450W, and I got it working for a day by remowing the CMOS battery, and ofcourse putting it back. It also now crashes while using Chrome Browser.
