Everyday or two days my computer crashes and freezes. my system spec's
Windows 7 64 bit

I do not have a clue why it crashes, i haven't got a single BSOD. and no it's not laggy, My mouse just freezes and i cannot do anything besides restarting the computer. I was searching on the web then my mouse stoped and i couldn't move it or do anything

Along with keyboard shortcuts and everything? the whole computer just locks up.
Not even pressing something like Ctrl+Shift+Esc? (Task manager)
How old is the computer, do you run maintenance and keep it virus free?
As well just to be sure, make sure it does not run hot and i suggest cleaning it out with compressed air, even a vacuum hose if you are willing.
One other thing, do you have all of your drivers that you know of installed?

My computer completly locks up and cant do anything, I think i have all of the drivers installed, installed the latest video card update and sound card. my computer is a year old and yes i keep it virus free, I don't think i have a can of compressed air but my computer does not feel hot when it's locks up

And what about registry cleaners did you use any of those? as well when did these problems start occurring most.

I have ccleaner and i clean the registry sometimes, and i forgot when this started to happen.

my power supply is probably freezing my computer after watching a 20-25 minute video, when my computer frozed i put my hand on the power supply and it was Spinning very fast. Is my power supply the problem?
