bootup stops after memory count

[Michael A]

Hi,
When starting up my machine, once the memory is counted,
nothing else happens! Devices don't get detected,
nothing! I've checked the memory and it is good. The
keyboard doesn't even get detected! Can someone shed
some light on this behavior?

Hmm. Try pressing DEL (or whatever) to enter the BIOS. Find the option
that sets "Default" level and select it. Save the change, and reboot. Any
difference?

Back to you.
Ron
