Still no joy.
Took my computer apart...
- my x1950 in his mobo, nothing
- his 2400pro in my mobo, works fine
We even hovered my computer over his to be able to connect my internal speaker to his motherboard. Still no beep codes with any component configuration.
Good idea Coldmast, i know its not a screw but it could be the standoffs. Unfortunately when i went to put my computer back together again I came back to find he had dismantled the HTPC right down to the HSF.
So... to save the hassle of buying more paste (closest computer shop is 50 miles away), if I were to fire up the motherboard with no heatsink... and free of the standoffs (on a piece of cardboard I believe ive seen people testing them on?), it might POST even if just for a second before the temp sensor shuts it down?
