W764b - Completely random freezes

Ever since I got this new computer, it freezes up at random. Everything just stops: mouse pointer doesn't move anymore, video freezes,.. it's like I made a screenshot and am viewing it in fullscreen..

The first crash I can remember is when I was installing World of Warcraft, I didn't think much of it at that time. Currently, these crashes happen more often and what annoys me the most, at completely irregular times. They have happened to me when I:

- Started up my system and I got to the desktop
- Started up my system and left it idle for a few minutes
- Was browsing the web using Opera
- Was editing video using Sony Vegas (Crashes seem to happen a lot while using this program, but they are still irregular)
- Chatting with friends on Xfire
- Starting up WoW
- Been playing WoW for a few hours
- ..

I don't get a warning or anything, my computer can be running smooth and just lock up 2 secs later. Something that also is worth mentioning, is the fact that sometimes I hear a weird sound coming from my speakers when it happens, this may be caused by the fact that it freezes while playing some sort of media file, I'm not sure. It doesn't happen all the time tho.

I don't seem to find anything in even log tho I'm not an expert in that area.
I don't get any type of error message whatsoever, which made it hard for me to look for a solution. usually I figure this stuff out based on error codes and stuff but no luck now.

I looked around on this forum a bit but no freeze problem seemed the same like mine so I decided to make a new post. Hopefully someone can help me fix this.

Thnx in advance.

Thank you for a quick reply :)

My system is set in Dutch, but i assume things look more or less the same.
I believe this is what you need. The times do seem to be the same times as when the crashes happened.

No idea what Kernel-Power is tho, hopefully you can tell me :)

I've never had a single BSOD and there is no folder named minidump in my c:/windows directory, not even as a hidden file.

Since it completely freezes I don't think my computer has the time to even display a BSOD.

My computer is brand new so I assume fans are in a clean condition and as far as I can tell they are working as intended.

If it is idd an overheating issue, I find it weird that i freezes immediately after startup, it shouldn't even have the time to get overheated at that point.

I added all files that might be useful.
