my pc is crashing down

Befor I format my computer I used to get these messages when I try to open the associated programs:

" Media center has stopped working"

"Internet explorer has stopped working"

When I try to open a folder or program I got this:
"Windows explorer has stopped working"

And sometimes:
"Windows sidebar has stopped working"
"IncrediMail has stopped working", and it shuts down and I couldn't open the program again till I restarted the computer.

I got Kaspersky Internet Security, and most of the times it also stops working and shuts down.

Some times, the computer restarts for no reason.
Other times I got a blue screen with writing, and I have no time to read whatever is written in it, because it restarts the computer within seconds.

I thought that the only way to solve these problems is to format the c: disk, but after I did I kept having the same problems.

And there are many other programs that keep stop working all the time, and sometimes I can reopen them after a restart, and other times I can never open them again.

Could anyone please help me and tell me what is going on with my computer

[COLOR=#ff0000][I]I did as written from the beggining of the rules, but when I got here I couldn't find this option ([/I][/COLOR][COLOR=#000000][B]Healing/Quarantine and Advanced System Analysis), what do you think has gone wrong?[/B][/COLOR]

You want to say that you don't have this option on picture? :

Yes, I don't have this option.
This is what I have:

Run the script at number 3.

While I was running the script the program stopped working, and I got this message:

Disable antivirus.

I diabled everything, and there was nothing working except the internet explorer, and of course offline because I disconnected the internet, and then I ran the program as administrator, and I'm still getting this message again and again...
I fed up with this computer, and I'm gonna throw it out of the window...
Pleeeeeeeeeeeeeeeeeeeese help me!!!:(

sorry! it was "disabled", and "Pleeeeeeeeeeeeeeeeeeease".. thanks

I can see nothing harmful in your logs. Your system seems to be clean. Try to install SP2 and all updates.

I cannot update my windows, because either updates or installation of these updates stop working!!

What is wrong with my PC!!

Come tomorrow. We will try to answer.

Thanks Aleksandra and rene-gad :), I'm downloading this program now, and I'll post the log as soon as I scan my pc.

MBAM has checked my pc and find no infected files, but anyway here is the log.

Yes, you're right. But now we can also eliminate any malware as a cause of your problem: Just 3 programs cannot find any malicious thing.
I can recommend you to make such steps:
- Remove [URL="http://virusinfo.info/showthread.php?t=42263"]Bonjour[/URL]
- Clean Temp-Maps, Cache of Browsers, Recycler. Use Windows service tool [URL="http://support.microsoft.com/?scid=kb%3Ben-us%3B315246&x=17&y=6"]cleanmgr[/URL] or [URL="http://www.ccleaner.com/"]CCleaner[/URL] or [URL="http://www.clearprog.de/"]ClearProg[/URL]
Try to install Sevice Pack 2 for Vista - it will possibly solve your problem :)

In addition, check configuration of the [url=http://support.microsoft.com/?scid=kb%3Ben-us%3B912923&x=13&y=13]data execution prevention[/url] function.The article is rather old but this function exists also in Windows Vista.

Thank you all for your help, and I'm sorry for disturbing you and for taking from your time.
I'm gonna do what you advised, and I hope this will solve the problem..

Thanks again :D
