**Help with my pc problem**

After using my Pc for a while it starts to run really slow. Then it starts to show ghost of windows and things I clicked prior. Then it will freeze up and it sounds a solid beeeep until I unplug. Then I turn it on and it works for a while then does te same thing.....what is the problem?
My Pc also wont keep the time?? Maybe I am forgetting to hook something to the mobo? Any help I can get would be helpfull thanks.

have you put the heatsink on properly? sounds like thermal protection kicking in.... and then failing.

Reseat the heatsink if this is a new build!
