Chkdsk "replacing invalid security id with default id" windows xp

[Paeday]

Hi,
I'm using an old Acer laptop for school and the other day I wanted to try to defragment and it wouldn't let me. The next time i turned it on the screen went blue with the "replacing invalid security Id with default Id" running line after line after line. Now when I turn on the laptop, the taskbar is gone, the wireless network is gone, my files are still there but I can't copy, cut or paste them. I'm a poor student with no resources to to have this replaced so I'm hoping this can somehow be reversed. I tried to run system restore and it won't let me. Please help I'm falling behind in school and can't always get to the computer lab, thanks

If you can enter the above type 'cmd' in the box then a black box should appear on your desktop

It should look like this C:\Windows\*your name*>

Enter this into that black box;

chkdsk /f

It will tell you you disk is in use would you like to recheck after rebooting?

Select Y, then reboot

Then see how you get on. This is a simple way of checking there are others.

A list of commands is below. Be careful what you use. If unsure ask first
