didn't help, still the same problem

Its like my system goes 10 times slower than normal and he won't shut off the power... evrytime I try to shut off or restart my pc it fails... keeps loading at shutting power off screen

[igor]

What exactly does it mean, "crashes"?
Bluescreen, or just avast! crashes, or the system freezes, or something else?

[Sion]

tbh he doesn't crash immediately only if I handle to quick... like opening 2 apps. If I wait its time evrything still works but really slow... when I try to shut off my computer its like he keeps loading for ages... so I don't have the patience to wait more than 5 min... its like he got instead of 4gig ram 10mb ram or worse...  

edite: no bluescreen, avast works fine but as slow and unstable as evry map, file or applications I try to open..., my computer don't freeze immediately I'm not even sure if he does freeze he might get just to slow to work...

[igor]

Well, it's really hard to say... could also be a hardware problem.
How does it behave in Safe mode - is it also that slow, or does it look OK? I mean, avast! isn't running in safe mode and neither are many other applications, but you can probably guess by trying to open a few things...

[Sion]

I don't understand what you try to say it only starts when I scan the system32 files and when the scan freezes at a file can't use avast in safe mode so can't try it

[igor]

OK, I didn't understand that - I though it's slow all the time.
How about a disk check (including surface scan) on the system drive?
Also, when this slowness occurs - is there any process using CPU, according to Task Manager?

[Sion]

- no its not slow all the time only when I scan one of these system32 files.
- a disk check pls explain more I want to try it
- I'm not so sure about it have to kill my system again to check it out

wow thank you Mr.Igor

I did step 2 the disk scan he found this "damaged clusters in file 24330 name \windows\winsxs\AMA022~1.163\DiagCpl.dll replaced." this was the first file the scan crashed with :O
now I can scan my computer again thank you Igor!
