Edit: ok getting "progress" this morning and need some help.
If I unplug the 8pin CPU power and turn it on it
continually runs; but with the obvious constant red CPU led and obviusly doesn't work.
When I plug in the 8pin cpu power, it starts up for a second, shuts down, starts up, shutsdown forever. Only this time the CPU le is blinking.
To ke this just says I need a bigger power supply;am I correct on this? My current one should be enough but it's pretty old and maybe just isn't supplying enough juice anymore; it's an antec truepower2.0 that's a couple years old
if anyone can help confirm this I'd appreciate it, thanks
Especially check the CPU fan connector. If it is connected to the wrong header, the CPU fan still spins, but the motherboard thinks the CPU fan is not connected and does not complete POST and you may possibly get CPU red LED shining.
This afternoon I'm going to test my MOBO with different PSUs, in order to check if it is the problem... because in the manual of the MOBO indicates that the connector needed is EATX12V, and I'm not sure if my PSU has this connector...
If it has the 24-pin motherboard connector and the 4-pin/8-pin CPU power connector, then that is it.
More importantly, your PSU should comply with specification version 2.2. You should check that. If you have bought the PSU recently ( within 2-3 years ), it should be of this version provided that it is not an old stock unit.
