Well, it's been three days now, no BSODs... It may have been solved by any of these three things I did.
1. Changed ram timing to CAS3.
2. Turned all APM stuff off.
3. Installed new SBLive drivers.
And I do remember something, this problem used to happen on my old motherboard as well. I'm not totally ruling out the problem yet, maybe after it runs for a good week or so, then I'll say its stable, but it looks good for now, been through games of Diablo II, NFS5, and Red Alert 2 with no probs.
