Do you remember when the last time was that you were able to install updates?
if so, please try the following as it should fix the issue
Click start, all programs, accessories, system tools, system restore..
Click, restore my computer to an earlier pont, then click next..

Carry out the restore. the computer will restart, then let me know if that fixed the issue or not..
