I have to say that I had an amd 64 bit machine running windows7 then8 then
10, one day it started to do this. The psu had gone but took the motherboard
with it. Salvaged still intact ram and an hd and dvd, chucked the rest
away.

Hello all. Can anyone help? My 64 bit Mesh machine (mesh computer nero

That's about 10 years old, and there may be hardware issues with the
motherboard or PSU.

The usual way to deal with this is to try each of these steps in order:

Clean all the dust out of the case.
Run the PC with the side cover off - are all the fans running?
Reseat all the RAM, and push all the plugs on the board in properly.
Check the motherboard for blown caps.
Replace the thermal paste on the CPU.
Replace the CMOS battery + reset the CMOS
Disconnect as much as possible from the motherboard, eg the hard disks,
USB devices, DVDROM, graphics card (if there's onboard graphics), leave
minimum RAM - try to get down to the minimum configuration that will POST.
Swap in a known-good PSU.

When you've done that please let us know the results.
