Understood.. When you do return home, what we should try and shoudl work.. Is a safe mode start and then a system restore in safe mode.
To start in safe mode.. When you first press the power button to turn on the computer, rapidly tap the F8 key.
This should take you to an advanced boot options screen, choose safe mode with networking.
Then, once loaded into safe mode.. Complete this system restore.
Click start, all programs, accessories, system tools, system restore..
Click, restore my computer to an earlier point, then click next..
We want to choose a restore point that was at least one day before the issues started..
Carry out the restore. the computer will restart, then let me know if that fixed the issue or not..
I strive to provide great service, and greatly appreciate a rating of excellent ( 5 stars ) selected and submitted below this answer or at the top right of the screen. I always answer follow up questions.
