Pavilion SL3850 freezes up

Hi, I have a Pavilion SL3850 that freezes up multiple times per day. When it freezes up, the system is not reachable though the network, and the keyboard does not react on events - the numlock led does not change. The screen remains frozen, with all text and images displayed as it was. There is no mouse response anymore.

The system is running Windows 7 64x. The fans are working, and I checked the system and memory with the HP diagnostics tools. I also replaced the root hard disk and restored the system through WHS. I also tried restoring the system to a month before the problems started, but it froze just as frequent. There is no indication in the system log about the freeze, apart from a report that it has stopped unexpectantly. This stop time is at the time of the freeze, not at the time when I switch off the system to reboot it.

What can this be? A PSU failure?

Any help would be appreciated, it is a nice system with Quad core CPU, it would be a waste to replace it.
