My laptop crashes during every single virus/malware scan!!

I already did everything on the ''read&run me first'' file exactly word for word and my laptop still freezes up during every virus/malware scan I try. I noticed the problem a few months ago when i had run Norton Antivirus to do a full scan. Halfway thru it, my laptop froze. I thought it was a random problem and force-shut-down and tried again. It happened every single time. So i uninstalled Norton and tried AVG. Same thing.

I have a 32-bit version of Windows XP and have uninstalled all my previous firewall/antivirus programs and installed and ran the ones recommended by majorgeeks following the step-by-step process exactly. Here is what happened:

SuperAntiSpyWare: froze before completion. Dont have a log. Seems to freeze while on the System32 folder (.dll files)
Malwarebytes antimalware: also freezes before completion. but i managed to stop the program just before it froze when it detected a few malwares and "cleaned'' them. Attached the log file. (also seems to freeze while on the System 32 folder (.dll files)
Combofix: computer froze before completion.
MGTools: also froze. Attached the log file.
RootRepeal: attached log

Please help!!
