Thanks for the replies!
Bloom, by frame buffer do you mean apature? I don't seem to be able to find a frame buffer menu item.. The bios was set to "optimal" by default and all seems stable.
I should point out that every thing works OK, I'm just concerned with geting the most out of this system.
I do have one configuration problem however...
After a long period of disk inactivity, such as spending an hour reading an HG, or game playing for an hour, my P.C. hangs on shut down. In a normal cycle, if I click the close down or restart button, it closes down (and turns off) fine. However, when it hangs, windows shuts down, but the power supply and CPU fan keep running. I can prevent it just by opening explorer and "waking up" the disks first. Any ideas? All power saving schemes in Bios and windows are disabled...
Again, thanks.
