It usually happens between 9:00 and 14:00 - Digital time (+01 UTC or something like that, I live in Copenhagen)
One day I got a BSOD, but with NO text at all.

I have checked that all the cables fit correctly, and they do. 100%. My graphics card is not broken, as I can play games completely flawlessly as I did before the crashes began to occour. Now what happens before the crash, is that the current frame displayed on screen freezes, and the speakers repeat the same sound over and over. Eg. if I am listening to music with iTunes/WMP a song that goes like "I love you, la la la la" will stutter like "I lololololololololololololololo.....". (LOL).
Then the screen goes black, and the computer says "beeeeep beep beep beep beep". 1 'long' beep, and then 4 'short' beeps. It keeps doing that, until I turn the PC off, and the power too. I wait 5 min. and restart, and then the computer works 100% the rest of the day. Next day, it does that thing again.
I think I know what the problem could be; I have been annoyed by the Vista LiveUpdate thingy, that usually every 2. weeks forces me to choose to install new updates, or the pc will re-boot in 4 min and 30 secs.
I then used commando prompt to stop it by typing NET STOP "WINDOWS UPDATE", and it works. The update thingy goes away. But what could be the problem? I have scanned my computer with the Kaspersky Online Scanner. No Viruses. Will it go away if I simply install all the updates?
Anyone who has ideas about what's wrong?
Thanks to anyone who can help me, as this is really pissing me off.
