This is a new thread regarding a previous issue that was ended due to it not being possible to resolve at the time despite all the time & assistance put in by makai.
I have changed the mobo for a known working one (MS6712 Ver 10a) but unfortunately i have the same problem
as before: no post or error beeps despite carrying out all the original tests ie bare bones out of the case
etc the result is just the same hard drive spins temporarily, all fans & optical drives work front & rear usb ports have power but still no signal to monitor.
The athlon 3000+ chip was cleaned & prepd correctly using arctic silver cleaning fluid/purifier & thermal paste applied, after cleaning there was no evident damage to the chip, no scorching or bent pins.
A couple of things i have noticed are: if i put a cd in either caddy the system sounds like it is reading them/ i am not sure what a hd is meant to sound like but mine appears to grumble 2/3 times on powering up but no clicks & also pressing the reset switch does nothing!
Any suggestions would be greatly appreciated as i am fed up moving jumpers & cmos batteries in the vague hope it just may work, thanks
