This one has me thinking I need to replace my late-2009 iMac post haste:

The screen sleeps.  And I can move my mouse or hit the esc key as much 
as I like; it's not coming back.  I have the screen-saver hot corners 
set so that the upper left corner will sleep the screen.  If I move my 
mouse up there (blind), and then move it back out, it wakes up.  Less 
than two seconds later it blacks out again, I wake it up, it gives me a 
second or second and a half and blacks out again.

I rebooted the computer, checked the disc, found errors and fixed them. 
 That was two weeks ago.  It went through this same shtick last week 
for a while, I rebooted and it left me alone again.  Today it was very 
aggressive, a reboot did nothing.  I did a reboot with 5 pram reset 
bells and cleared the SMC (sp?) by unplugging the computer.   Still did 
this endless repetition of sleep.

I rebooted again with all USB/Firewire lines detached, also did 7 pram 
resets (bells).  This time it was peaceful.  I went to system settings 
and reset my hot-corner to the bottom right.  On one occasion, last 
week, I turned the hot-corner sleep setting off altogether, and had no 
way to get it to wake up at all.  It does recognize the hot-corner 
removal to wake up again.

I've never had anything remotely like this happen until this week, but 
had noted in recent months that after waking up and moving to another 
space that it would sleep the screen, but a regular mouse-shake or esc 
key would wake it up.

Any guiess on what is happening here?
