About a year ago my computer was fine but it got a bit overloaded so I decided to reformat.
After that it was fine still, yet sometimes when I booted it up would freeze on the Windows XP login screen or as soon as I logged in. This being the whole system would just pause and I was unable to do anything. It wasn't a problem at first but it started occuring more commonly. During my games or even when I was browing the web my system would just come to a halt.
A few months ago I had an error message interrupting my games saying my graphics card had not enough power. However it stopped arising so I haven't thought about that, however all the power cables needed are plugged in properly.
As of now, I turned on my PC and hear no beep, and see nothing on the screen. I am really confused as to what this could be as I could not even format my computer as it just froze. I am wondering whether it is a faulty graphics card, power supply or software.
Thanks for reading.
