I'm sorry about the issue. Please try this: turn off your computer. Then turn it on, and right after the black screen with white text or the computer company logo disappears, press & release key F8 repeatedly until a menu appears, then you select Safe Mode (note: if there is no menu, then try the same steps again, but this time, press key F8 a bit earlier). Then login and click Start->all programs->accessories->system tools->system restore and restore the computer to any date before this issue has occurred, then wait until system restore finishes, then check.
- If that does not work, please try this: go to Safe mode again with the steps above. Then do the following:
In Safe mode, click on Start, All programs, Accessories, Run... (or press at the same time the two keys Windows and R), then type:
then click OK.
Then click on Add..., then give it a user name you want, then Next, and password, then next, then select the Administrator option, then Finish
, then restart the computer normally, then log in the new account and see if you can use the computer in the new account.
