[HELP REQUEST] Date&time Constant error. Urgent

Hi, since the arriving of the new year i have been gettin some errors about the date and time...but not some normal error that may pop up and u hit cancel and ignore or somethin and it wont bug u anymore...since the time of every second is invalid according to the computor, i keep gettin errors every second...I have tried changin the date in so many forms backwards and forwards so no need to point that out...i even took the time to do a complete scan on the pc to see if it would've caught any virus or somethin...but still im clean and it continues =/
If anyone has had it and/or knows how to fix it, i would be rlly gratefull since this is rlly annoying and it lags my pc like hell =/

SS:

Have you tried a System Restore? Safe Mode?

I can be abit "thick" when it comes to these stuff =/...never heard of them so dont rlly know how to do it

To access Safe Mode, as your computer is booting up, press F8.

Thx alot System Restore Worked hope it wont come back though...would have to have to restore the pc everytime it would come up =D
