Windows 7: Start Menu wont stay open!!!!

Hi guys

Ive got a big problem since 2 days.. When i try open the Start menu and search for something my Start menu close immediately and when i try to open "run" my start menu close and nothing happens...
Also my Windows is flickering...

Please help me i reinstalled Windows 7 and i looked in the Internet, but no 1 got this Problem...

Thanks

Peace

Welcome
Two things to try
First try a system restore from 2 days before the problem
The next solution is to make a new user account. The one you are in is corrupt
System Restore

Hey richc46

i used the system restore but nothing happened.
i try to do this with the Account i let u know what happened

Thanks for your reply

Sorry that SR did not work. I am very confident with the new account, however.

No i tried it and nothing happened

WTF i never heard of such a problem

You opened a new user account and start menu still would not stay open?

If yes try this
SFC /SCANNOW Command - System File Checker

Yes i made a new Account but its still there and i tried also Sfc /Scannow but it found no problem..
But thanks for your help
I think its because i used a Windows from Piratebay... i used it cause i dont have a original disc but a original key

Did you boot the computer after the new account?
Try the start button in the new account

Alright i reboot my Pc now with the new Account

If the start button works with the new account, you have to use the new account.
