[Raging]

since yesterday everytime i reboot my comp it freezes at logon

it gets to the login screen and i put my pword in and press enter then bam it doesnt do anything...

to get back onto windows i haveto switch off the psu switch when booting to get up the safe mode option and go in and do a system restore for it to let me log back on,after the pc reboots from system restore it logs on ok wtf?

i havent done anything to the pc lately.

Load the Recovery Console from your XP CD and do an fdisk /mbr

Altenatively since your registry backup in System Restore is obviously good you could try this:

It repairs your Master Boot Record which may be corrupt.

However, given that you can get into Safe Mode and do a System Restore suggests the MS Knowledge Base fix might be a better option.

The fact it keeps getting screwed again after a successful System Restore, when you boot normally and enter your password could be symptomatic of a Sasser Worm infection.

Download Stinger from McAfee, save the exe to your desktop and then boot into Safe Mode (with any network cables physically disconnected) and then run Stinger.
