Not sure if these will work, but try one of these:
If u can get 2 a corner of the screen, drag instead of just enlarging the screen. When the screen is back to the right size, then just click in one of the bottom corners, at the screen outline. This should "set" the screen.
Or:
Go to control panel. Click on display, then settings. Reset your screen resolution to whatever it is supposed to be. Click "apply" then "OK"
Or:
Do a system restore back to a time before whatever time it was b4 your wonderful husband did whatever he did-an hr B4, day B4 whatever.
OR:
Tell your husband to pay the bill when u take it to be repaired
Good luck-hope its fixed soon!
