There are many reasons your computer freezes, some of which can be attributed to application errors, faulty hardware, overheating, driver incompatibility, software problems, and registry corruptions.

It’s really a case of trial and error finding what the problem is. If it has just started happening recently then think about the software you have just installed or system changes you have made and try reversing them.

You can try reseating the ram by taking the sticks out of the motherboard and placing them back in again. You can also try leaving one stick out and testing to see if that’s the faulty stick.

To check if your cpu is running too hot restart your computer and press Esc or F10 or F1 or F12 depending on your computer. It should give you a message saying “Press XX to load bios settings”. From there you will be able to see what temperature your cpu is running at and you can check that against what your manual says it should be at.

The most common and easiest problem to check for is registry corruptions. The windows registry is prone to errors and corruptions because it is constantly being added to and deleted from by third party software applications.

You can easily run a registy scan to diagnose whether your computer has registry errors or corruptions using leading registry cleaner software. I have heard back from many people who have had this problem that have said there computer stopped freezing after one scan and even started running a lot faster.
