Yes my system is old, but it hasn't been any trouble at all until last week.
Last time I used it, Windows wanted to do an update, so as I have countless times I chose "Update and shutdown" and left it to get on.
When I came to restart the next day - stuck in a loop, never even getting to BIOS. Error code '00', at least at the point of restart.
I've tried:
- Updating the BIOS using Flashback
- Disconnecting all drives
- Removing the GPU
- Re-seating / swapping the memory sticks around
- Trying each memory stick individually
- Removing and checking the CMOS battery (still at > 3V)
- Resetting the CMOS with the button
At present, there are no drives connected, no GPU. I'm using the on board HDMI to connect the monitor.
Still the same restart - 2-3 secs of power - shut-down - restart loop.
What could / should I try next?
