ratsarsse & Mac the Knife - Yeah, I am begining to think its the PSU ... The current one is a 300W unit, maybe its being overloaded, probably the cheapest component to eliminate before moving onto things like CPU etc ... ...
(I have heard that for a >1.7Ghz CPU + a 7200 RPM HD a 400W PSU is recommended ?)
I installed some monitoring software supplied with my Asus motherboard, it draws a real time graph of core voltage, CPU temp, and 12 volt supply etc ... useful info ....
The CPU seems to be running cool, and the 12 volt supply is steady.
But maybe the load is too much for the PSU and drawing too much current that the PSU resets automatically ? (even though its supplying steady at 12V). Do the PSU have auto resets when the load gets too high ?
One other thing, my speakers run off an inline socket on the back of my PSU mains socket, I wonder if this is not a good setup, or their is a flaw in that connection .......
Thanks to all for the advice
