Can't log in in windows xp

[timtheenchantor]

I havent updated anything or had any system mods except for mcafee in the morning...

Arg I try to log in and all it does it try and it logs me off.. I tried to boot from a windows xp cd and it wont let me...and I dunno how to enter Safe disk, it ctrl or f8 repeat initiates it, then it doesnt work. WTF IS GOING ON.

it may be time to bite the bullet and reinstall. booting from cd as the first boot device is enabled in your bios, by the way? remember you MUST press a key to boot from the cd when it asks you, otherwise it will boot from the hdd.
