This is a rather old issue, pretty sure I've run into it at least once on every computer I've owned.
You power on your pc. Everything lights up, all the fans spin. [NO SIGNAL]
So you check the cable, no luck, you unplug all the perifs, no luck.
This is when you go past end user
You crack the case, unplug the hard drive. No dice.
Next step says to unplug the video card, but you don't have a screwdriver handy, so you pop the ram sticks
You get a nasty droid blatting from the PC because ram not found
You put the ram sticks back in
PC boots normally
I want to know who put "have the fans spin up, but don't boot the machine" in that order of operations and give them a solid thumping.
It honestly seems like the PC is having a toddler fit and refusing to start up unless you change its ram checksum.
