The screen froze with the screensaver 3D logo in a tinyshrunken box on my trusty Pavillion A10. It was unresponsive to keyboard or mouse input (wouldn't wake up), so I powered it down with the front panel push button and powered it back up but...it wouldn't boot. No beeps, no text, nothing on the screen. I powered it down and pulled the RAM and powered it back up and got 5 beeps. I was hoping it might be the PSU, so I pulled it and switched it out in another system and that system booted so it's not the PSU. This system has been in a clean air conditioned environment on a surge protector. When I pulled the lid, the interior was unusually clean and lint free.
