When I turn on my computer it shows nothing but a blank screen. Doesn't even go into bios 19 out of 20 times. Every now and then it boots into BIOS and begins loading Windows, but freezes at the loading screen. What could the problem be? A couple months earlier the computer would randomly shut down while I was using it. I'm assuming the problem might be the probably the power supply. It's an emachine t3624: http://emachines.com/support/product...s&model=T3624#

And yes, I know I really need to upgrade to a new computer... but I have absolutely no money I can put towards buying one at the moment. It would take me at least a couple months to be able to afford even a cheap one....
