The readings are from SiSoft Sandra. I also ran Aida32 and came up with similar readings. I have been trying to track down various little faults that keep cropping up, all started with the mouse that refused to move in the horizontal plane unless it was attached to a KVM switch and the other computer was turned on ( didn't work with a USB mouse either). Then the sound went, then the monitor wouldn't come on unless you did a full re-boot 3/4 times (funny enough that started working again this morning), then the odd setting would change, such as forgetting my Pprune automatic log on when the computer starts up, open programmes getting stuck on the task bar when minimised, USB ports not recognising plug and play and other irritating little things that just don't make sense.
I have got so fed up with it that I have bought a new MB and will be installing it next week. I am running XP pro, Athlon 1.7, 256mb DDR and plenty of HDD room as I have recently reformatted and reinstalled XP in the hope that it would sort these problems out, it didn't.
It was only this morning that I seriously considered the PSU as a sort of after thought, everything else seems to be OK including memory. The system is also virus free.
