Well, I've been experiencing problems with my PC for a few months now and still have not found out the problem with it. Let me elaborate, when I play games such as CS:GO or a Call of Duty game (both which I have tested and got problems) my computer just shuts off, no shutdown sequence just a sorta power cut. I have trouble finding the cause of this mysterious problem and wish to resolve it.

How and what would I use to help diagnose the issue I'm having? Also, any teamviewer help or something is extremely appreciated.

Probably because the PSU you chose was not even designed to output the amount of power that your components are drawing, And for the cheap price I'm not surprised.

I'd recommend upgrading to the better unit as fast as you can and avoid any 3D gaming in the meanwhile, If you stress your current PSU any more it is possible that it will explode and potentially damage parts in your system that you paid hard-earned money for.

You'll also be surprised at how much quieter the XFX unit is.

Whenever I've experienced sudden shutdowns, I have solved them with driver updates. If your shutdowns happen when playing games, the video driver and or video control panel woud be the main suspects, other possible causes would be the power supply and it's connections, and defficient CPU and video card cooling,

Other fixes I've done are the usual security scans, power settings ajustments, disabling startup programs, temp file cleanups, checking AC/DC power and digital connectios, diskchecks, defraggs, etc. though driver updates seem to be the solution specially when the shuitdowns happen after clean installations.

In my experience Windows Visa 7 and 8 seem to suffer from a sort off outdated driver "syndrome", when previous windows editions were not that obvious.

I'd suggest checking for a dumpfile in case it's created after a shutdown and or enable pausing the BSOD to read the error codes, or checking with a dumpfile reader... download links provided here:

My Specs:

I just reinstalled Windows and still the problem persists.

*I forgot tot mention in the first post that before all of this happened I was playing a game and suddenly I heard a large bang and the power supply was no longer functional so I replaced it and have these problems.*

*This only happens with more graphically demanding games, not games which use less 'power'*

My power supply: CIT 550W Gold 12Cm Silent Atx Power Supply

How about this? Corsair Builder Series CXM 600W Modular

The shutdowns are very likely caused by the PSU not being able to supply the required power requirements of your system, the shutdowns during 3D gaming heavily points out to this.

The CX600 will do the job but its capacitor quality isn't the best you can find for that price.

I'd recommend this unit, Shouldn't be that much more expensive and has good quality Japanese capacitors that'll last you a long while.

Okay I will look into this. Also, when playing more graphically intensive games I can hear the fans and the power supply go into overdrive and I feel the PSU gets very hot.

Sounds like a PSU capacitor blew up... and that may have affected the GPU in some way that it fails on more intensive games. The cause that comes to mind is GPU overheating from the PSU sudden failure to power the GPU cooling fan, or maybe an unregulated power burst right before failure, burned something in the GPU.

Actually, I just put my old GPU into my computer and I have not received that restart, its just laggy as its a bad card. Why would a GPU cause a computer to restart, I thought that would of been the work of a CPU or PSU
