Hi,
I want to share an interesting one with everyone.
I had a machine boot then turn off and boot again. It would do this as long as I let it. An endless loop!
So after searching everywhere on the web for an answer , I removed the new MOBO and replaced it using new risers with insulating washers.
Still no joy.
I put in a brand new 400W PS and with no cards or USB devices to drain any power and no joy!
Then as I had the HD out of the case, I hooked it up and it booted and stayed solid!
Over and over I tried to get it to fail. it wouldn’t!
I remounted the HD back in the case and guess what? PC we not go back into its boot-reboot-boot reboot loop!
So I removed and remounted the HD in upside down.
PC works great!
The offending HD is a Western Digital Caviar WD800BB 80 GB.
