Thanks for the help people are providing
I have done a virus scan with emsisoft in safemode and found a few viruses, being trojans and backdoor's etc and deleted them, also running it in safe mode, and i still have the same problem.
I have done a hardrive scan with the actual software for the hardrive, no bad sectors found, aswell as the chkdsk command, the chkdsk being run in safe mode and found 0kb of files in bad sectors.
I also found that i could not use the internet as neither internet explorer or mozilla firefox would connect to any website, so either the user profile is corrupt, or i still have a virus that is not being detected or not being deleted, so i will try malwarebytes and see what happens there
EDIT: Malwarebytes detected a virus, a trojan in avast that i downloaded yesterday, from the actual avast site. It did not delete it, so i had to manually uninstall and delete avast. I can now get acsess to the internet.
I did the chkdsk command again and found out that it was:
'repairing volume bitmap'
'found errors in the file system'
Im guessing its probably worth doing a repair install of windows xp?
Thanks again for the help
