A few weeks ago my PC began demonstrating a number of pecular symptons - like crashing during games (Rome particularly, but during other activities as well). When it finally would not reboot at all I took it to a local shop. They said it was the Motherboard and replaced it.

That was 1 1/2 weeks ago. Now, games lock up and regardless of how long one waits for it to unfreeze or trying ctl+Alt+del, nothing happens and I am forced to shut it down manually. I tried leaving it on one night and the next morning it was locked up again (fyi - hybernation was not allowed).

Now I have run diagnostics and all the fun check system goodies that tell me everything is Okie dokie. It ain't.

My question is, is it possible that the new motherboard (mainboard) simply is not sophisticated enough for the other hardware? Or, could it be the CD-RW Drive (52x32x52) or gamecard (Radeon 9800)? Though I can't see how they could effect windows from locking up.

Any input would be welcome, as I am taking it back in on Monday.

Thx
