For dying computer owners: before upgrading anything, use a known good PSU. I just lost a week worth of late nights trying to set up a new computer. I deducted that it was the PSU on the nearly functional computer that had caused CPU failure, by having something else than DC voltage. On the average the voltages were a bit low, but contained AC spiking.
That CPU didn't work with decent PSU (normal voltage levels) anymore, on any board I tried - the other boards didn't even boot into BIOS. I had three PSUs to test and always it was the old one that made the old board work so well that I could install Ubuntu Studio and upgrade it even once, but then I got jams and interrupted HDD writes. I postponed indefinitely testing the other boards with another CPU because I had an older computer that had no problems - and still runs fine. PSUs are dangerous! :) ke 10. huhtik. 2019 klo 9.33 david ([email protected]) kirjoitti: > On 4/8/19 10:37 PM, D. Michael McIntyre wrote: > > I haven't tested the timing thing either.
