Laptop freezes after one hour

[turgenjev1]

Hello,

I'm having problems with my HP laptop with Windows 7. It works great, but after about an hour the system just freezes?! The whole screen goes black and only the cursor is blinking.

I've scanned my hard drive and it doesn't have any problems. I don't think that I have any viruses on my laptop.

I've tried reinstalling the whole system, but with no luck, every time I encounter the same problem.

Does anyone know what the problem could be?

That sounds more like a hard restart since a blinking curser is almost always a computer getting stuck looking for something to boot to.

Are you using any SW to monitor your temps? (such as HWINFO)? Also I would suggest running http://memtest86.com/ free version just to rule out a RAM issue.
Also look at event viewer - custom logs- admin. events
