bump ok i found it in boot execute whilst on my other user account, i unchecked it, restarted, got to the screen where it usually starts to scan and it said it couldnt find the program or something, so it just carried on to load windows... but then my pc was running really slow for a while, processor was showing 65-75% usage when i wasnt doing anything, i checked the processes and there was nothing there. it seems to be ok now for some reason, but i still cant analyze or defrag my drive with diskeeper, it says that CHKDSK is still scheduled to be run and i should let it run then try again, but like i said, it will run, fix stuff, then on the next restart it will do it again....... :@ edit: ive fixed it now, no further help is needed. w00t
