Vista - Vista 32bit is freezing.

Hello everyone.

I'm having a hard time with my vista when I'm playing some games. When I try to play ex. COD4, wc3 or crysis my vista freezes like for 5-20secs and then it come back to normal. The newer (better graphics, etc..) the game is then it's most likely gonna freeze. When I bought my comp I could play almost every game (without freezing), but not anymore.

I'm wondering is it because of some virus or just a vista bug? I've noticed that if I alt-tab in-game csrss.exe or dllhost.exe is taking A LOT OF cpu-usage. /: I guess that ain't normal? I read some other forums and I noticed csrss.exe has something to do with vista's graphical stuff. Since my comp is only freezing when I'm playing something I think csrss.exe is the problem.

I've ran many malware-removals and virus scanners. But they aint helping. I'm pretty hopeless atm. If you guys can help me somehow I would really appreciate it!

edit: My vista is about 10 months old. I haven't encountered this kind of problem before. I got vista SP1 installed. And I have to mention that my comp boots really slowly. I tried this one and my result was ~300secs.

Best regards,
E

Try some basic maintenance first. No infections?

Run the CCleaner: Download CCleaner 2.12.660 - FileHippo.com

Run the full disk check

Defrag

If still having problems use the system configuration utility- selective startup and see if the will help to narrow down the problem. Help for this is available in the utility.

Hello,
glatzfront

I have already tried these things:
CCleaner
Malwarebyte's Anti-Malware
Kaspersky Online Scanner
Avast virus scanner
S&D Spybot
Ad-Aware
JkDeFrag-3.36
ATF-Cleaner
+ some others.

Some viruses (and bad registry values) were found and deleted. But it didn't change anything.
I tried sfc /scannow and it found something that needed to be repair but my vista couldn't repair them. And I'm having a hard time to understand the logfile.
