Hello,
Don't know if this is a power supply issue or mobo, but am suspecting power.
System: mini-itx 2699 system from LogicSupply, EPIA M10000 mobo, about 4 yrs old, Morex2699 case, external power brick with internal 80W DC/DC converter. System has run almost 4 years solid, rebooting only for updates.
Problem: For a number of months it was not holding bios info, rebooting badly, and, finally, now does not boot at all. CPU fan does run, but no HD light, and case fans don't spin.
Discoveries/attempted solutions: When opened up, data ribbon cable to HD was frayed, lots of copper exposed.
I traded that cable out for a new (sealed plastic bag) cable; no diff.
Replaced CMOS battery (battery tested - good). No change. No beeps, no video, no HD front panel light, and HD does not spin (no vibration felt).
Reset CMOS per instructions (pwr off, change jumper, change it back). Even disconnected HD and CD drives.
No change. CPU fan and power light on, no beeps, no video.
Am suspecting partially failed DC-DC converter board. Is there anything else I can try, without a voltmeter to actually test output of DC/DC conv. board? CPU fan spins, front panel light goes on, otherwise no sign of life.
Will see if CPU fan and case fan voltages are the same, and connections, if they are, just to see if case fans are toast, but I don't want to replace working parts if I can help it.
I don't have a spare ATX PSU, so I can't plug that into the mobo.
Any ideas?
Thanks in advance -
