Last PC I built 2+ years ago has been rock-solid. No signs of impending
doom, but today it will not boot.
Mobo LED comes on, fans spin up, the HDD light is on but stays on and no
HDD
activity. No BIOS beep.

Have tried removing everything, swapping HDD, video card, and memory.
Only bit I can't swap is CPU as don't have any lying around.
Just curious if anyone else has experienced this? It's the 2nd time for
me - the first was after a lighting storm in the area - same symptoms and
a
mobo swap got it working again. But there has been no lightning today...

UPDATE
OK I tried two new PSU's - no go.
However something very strange that I have not heard of before - I can start
the PC by blowing on it!
No Really - last night having tried to get it running umpteen times and
running out of ideas, I was feeling pretty deflated and must have let out a
big sigh / puff of air and I suddenly I got the elusive POST beep, and it
proceeded to boot into the OS as if nothing had happened. I put it down to
coincidence.
I added back all my cards and drives, rebooting after each addition - all OK
Then this morning back to square one - it would not POST. All fans on, power
and HDD lights on, but no beep / boot. Nothing ventured nothing gained I
just took of the side panel, took a big breath, and blew onto the
motherboard - and again it has started and I am using the PC to send this
post.
So now I have a real mystery - what could be preventing the POST that is
cured by me blowing the PC?
Any suggestions much appreciated
Graham


I'm guessing your breath is cooling something that could be initially
overheating when the machine boots up? Or your breath is getting a
fan moving that otherwise would not be moving without assistance?
