Windows 7 programs don't start

[Nijntje]

Hi, I'm new here!

I have a problem with my Windows 7. I bought a laptop in January and until yesterday it worked fine. All of a sudden, it wouldn't close my tabs in Firefox.
Then it wouldn't open VLC Media Player, games, ... nothing. Not even the Configuration. The loading symbol comes on, then just goes away and nothing happens. When something does open, it's very slow and stops working.
I get white shapes when these things happen (even with the Start Menu).

In Safe Mode everything works fine.

I have tried scanning with Avast, Malwarebytes, Microsoft Security Essentials and CClean. Soms files were deleted, and now the scans come up clean.

Does anyone have an idea how this problem is caused and how I can fix it?

Thanks!

Try a System Restore to a time prior to the beginning of the problem.

i have tried that, but it seems i forgot to make system recovery points, seeing as my computer isn't that old yet.

Welcome to the forum
Try the SFC /SCANNOW

Maybe you are hit by a new malware or a trojan horse.
go to this site and don't forget to choose the relevant scanner for your OS ( 32 or 64 bit ).

Microsoft Safety Scanner - Antivirus | Remove Spyware, Malware, Viruses Free
The scanner is about a 72 MB to download.
Good luck

You have system restore points. Win 7 created them. Only by using one of those wonder programs to speed up your computer, etc can you not have restore points.

Use this procedure please:
RESTORE TO A PREVIOUS SYSTEM RESTORE POINT
1) WIN | type SYSTEM RESTORE | ENTER | NEXT
|Choose a different restore point radio button
| NEXT


2) Show more restore points checkbox (lower left)


3) Highlight the desired restore point


4) Scan for affected programs (lower right)make a note of affected programs
5) CLOSE | NEXT | FINISH


WIN = key with the wavy Microsoft flag on top.
