I powered off my Revo this afternoon to change the power strip, plugged in a second USB hard drive and booted it up, only to find the machine won't POST. It's been running happily as an HTPC for at least 9 months and has been rebooting fine. I've tried all the usual approaches - removed all external devices, BIOS reset jumper, moved the RAM around/used only one stick, even removed the Wifi card, and I still get nothing on the screen either by VGA or HDMI. The fan spins up to 100% and stays there on power-on. Googling reveals no other person with this problem, can anyone help? It's a Revo R3600 (Atom 230 HT), made in 2009, with 2GB RAM and original ION chipset.
Edit: Tested the PSU and it shows 17-18V (can't get a clear reading, but looks about right, says 19V on the unit), tried different RAM and removed the hard drive, no joy. Also checked for any suspicious burnt electronics and can't find any. Would really like to resurrect this machine as it's the house media centre and server.
