My computer keeps freezing. Please help

[Tromboneninja]

So, my computer keeps freezing, (as you probably saw from the title). I will be just on my desktop or in a game or doing something, and it completely freezes, my keyboard stops working and my mouse won't move. I can't Ctrl-alt-del or anything, and the only way to fix it is to hard reboot it. And this only works for a while, it seems random, but it will just do it again.

 

     I've been browsing through many forums and things, and haven't really found anything.

Radion HD 5770 (i know it's old and i'm looking to upgrade it soon.)

Check your memory with Memtest86 or Windows Memory Diagnostic, it may be bad ram.

I was monitoring it with HWMonitor. nothing seemed high at all.

In task manager I have just noticed that my disk is at 99% use. I don't think that is good.

I just did a ram test and it came out negative.

If negative means that it gave no errors, then move on to an HDD test with HDD Regenerator, or your favorite disk scanning software (unless, you have an SSD, never do that to an SSD). If it comes out fine too, then a windows reinstall is in order.
