Dell OptiPlex won't boot

I have a Dell OptiPlex 755. After a recent reboot, the system doesn't boot- the Dell screen appears, then the Intel RAID status (has a RAID 1 array), but then simply a black screen. I never see the Windows screen and pressing F8 does not bring up the Windows start menu.

When running Dell diagnostics, the initial tests all pass, but when hitting a key to open the diagnostic partition, it hangs there.

I ran memtest+ from the UBCD for several hours and no errors- system booted just fine from the CD.

However, the Seagate diagnostic program also won't load (also from UBCD).

I've tried swapping RAM chips and resetting CMOS with no progress.

Any ideas?
