Computer freezes up

I have an Acer Aspire 1830-3595 laptop with an Intel core i3 processor running Windows 7. Lately it has begun to freeze up. It first seemed to happen when the computer got hot or was worked hard with a lot of programs running. It does it more and more, and now the laptop has become basically unusable.

When it freezes I can see that no disk access is taking place. If I hit "control alt delete" nothing happens. I cannot get anything to work to unfreeze it, and have to push the power button in and do a hard shutdown. Then Windows gives me an abnormal termination message when I boot up again.

Is there anything I can do to check what caused the freeze-up?

Thanks.

 

Thanks, Arie. I had to run the command in Safe Mode, and it generated 967 pages. Should I post it all? Or just the first few pages?

Unfortunately, I do not have any backup disk from Acer. I bought the computer refurbished, and it did not come with anything like that. And I would like to avoid having to reinstall all the programs I have on the computer.

For now I can get the computer to work by rebooting it if it crashes and making sure I do not have too many web pages open at the same time in Google Chrome, the browser I use. The crashes seem to come when I have several webpages open at once.
