So previously i had another start up problem http://www.sevenforums.com/general-discussion/306008-start-up-problems.html so i decided to use the repair my system option after pressing F8 before windows booted up i tried to start up repair but it gave me an error saying if i have an mp3 device, etc inserted, eject it and restart and try again. Then i tried system restore but it also gave me an error (0x8000ffff). then i decided to check for hardware memory, it detected and fixed nothing but after i restarted and logged on i was left with a black screen with no desktop, i am able to open task manager to open other programs but i think i can only open browsers. it took around 5 minutes or more for my desktop to load up and my taskbar to appear. Please help me i am willing to try all suggestions. Also i have noticed that my computer time went ahead i had to adjust it using internet time. After eevrything loaded my computer works fine and is quite fast.
Have you tried booting into safe mode? If so , what results. You could try running sfc/scannow from safe mode if possible. ascomputers is correct, we could use a little more info here.
We have many fine tutorials here at the forums, written by some very capable people, heres one for the sfc/scannow. Just click on the link :
Just to look at this in isolation. This would indicate that your CMOS battery needs replacing!
