Vista - Laptop freezes

Hi there, I have this huge problem with my laptop, it's always freezing. It's freezes about 10 to 15 times a day, even if I'm just working on Microsoft Office. Sometimes it freezes just after the boot. When it freezes nothing at all works, I can't do Ctrl+Alt+Del, I can't move the mouse and the only option is to remove the battery and then reboot it.
At first I thought it was a registry problem, so I downloaded a program to clean my registry but the freezing continued. Then I thought I had some sort of a virus but my scan showed that my computer is virus free. Then I downloaded Mestest86+ and ran a memory test but it showed that I have no memory problems.
I don't know what else can it be...Thanks in advance for any help.

You haven't said whether you've tried a System Restore from Safe Mode.
Restoring to a point before the problems began may help.

Thanks for the response Indeed, I haven't tried that. How do I do that? It's just that I really don't want to do a full system restore...

Grrrrrrrrr

there is a great tutorial on how to do a restore here Restore Complete Computer

Hope this helps

If you don't want to do a full system recovery, you can do a simple Restore from Safe Mode like this:

Shut down your PC. After a few seconds, start it up again, and immediately begin tapping continuously on the F8 key.
When a text menu shows on the screen, be sure that Safe Mode is highlighted.
(You can move between choices with the arrow keys on your key board).

With Safe Mode highlighted press Enter.

Once the Safe Mode desktop loads, click the Start orb, type Restore
and click on System Restore at the top of the menu.

The System Restore wizard will guide you. Choose a restore point before when the problem began.

Hello grrrrrr,
Have you looked at the startup/service's programs to see what is running, maybe a software conflict.
Go to search and type "msconfig" enter, and open startup tab, look there and then open services tab and look there.
Hope this helps, post your results, good luck.

Sorry, I've been away for the past week but now I'm back

@Ardneh
Whener I try to do that it fails, and it shows an error message saying that it couldn't complete the System Restore...

@stoneys-nutz
I'm sorry but when I look at that what should I see? I don't really understand that, I'm not that much of a geek

The fact that you cant complete a system restore may suggest that there are files that need sorting out first.
Follow the instructions in this tutorial and repair the system files first.
Then we can look at the programs you have running.
Good luck and post your results.

What security programs have you installed on your system grrrrrr?
[I'm doing some lateral thinking.]

Thanks for the responses. I'll give it a try @stoneys-nutz.

I have Panda 2010, Malwarebytes' Anti-Malware and Spyware Doctor. I know I should only have one but I had the Windows Security Suite problem and in order to remove I needed those last 2 programs. What do you think it might be?
