Vista freezes except for mouse

Whenever I boot up my Dell Inspiron 1525, I'm able to do a couple of things before it freezes on me. I can move the mouse around, but am unable to click on anything. I've tried system restore twice, going further back in time the second time, but it hasn't really helped. I've been recording video with my webcam recently, could that be contributing to this? I have vista home premium. Any help troubleshooting would be much appreciated! Thanks.

Welcome

Here are my solutions to freezing, and an excellent article, which I hope is of some help
Go to search type device manager and look for any yellow warning markers
Download and run malwarebytes, a full scan after you update
Run antivirus scan
Check memory with memtest86
Make sure that you are not over heating.
Try in safe mode; report back if it works properly.
Try a clean boot
Make sure PSU is working properly
If overclocking, restore to original
Test hard drive at company website.
Test in safe mode, does it still happen?
Try with clean boot..

Thanks richc46, I did a clean boot, downloaded and ran malwarebytes, and downloaded a program that cleaned the registry. I didn't see any yellow warning markers in the device manager. Things seem to be better, though I'm still operating in clean boot mode. I'm going to resume video recording tomorrow, hopefully things will continue to be trouble free...
