Completely random freezes in Kalyway 10.5.2

[Lonz]

Ok, well this was my first time trying osx86, and it went really well, I had some problems installing at first, but I just needed to disconnect my IDE hard drive and use a different IDE DVD drive for the disk set as master, I then installed onto my SATA drive. Ok so found all the drivers and it went great, runs smooth as hell especially for my specs. But not it randomly freezes, I could be reading email or just on adium, or could even just be sat on google, it is completely 100% random, I can be doing anything. However I have noticed that if I leave it on all day whilst I am at college (about 8-9 hours), I come home and it is fine, screensaver is on and It comes out of it fine, but as I start doing stuff, eventually it will randomly freeze whilst I am in the middle of something, can anyone help please?
