1. One of those bootable antivirus CD's from http://www.techmixer.com/free-bootable-antivirus-rescue-cds-download-list/
2. See if it boots in Safe Mode, although it's doubtful you will be able to find the cause then. However, having a look at the startup tab of msconfig won't harm and might reveal strange things.
3. Back to where it all begon: a clean install of Windows XP from 'system recovery' disk. You might lose all that you don't have backed up to another medium.

I don't know but lately my computer has noticeably slowed. I started deleting some files because I thought it is just a low available memory issue. But it didn't solve the problem. Days later, the computer freezes even if I am not opening multiple programs at the same time. I tried updating and scanning for virus but there isn't. And now, it turns off itself and reboots. I can't afford to buy a new computer and I know that there is a solution to this. I know this is just a piece of cake for experts and computer savvy people.
Any suggestions on how to fix this? Help. Thanks.
