Tags: Homebuilt CPUs Motherboards Power Systems Product Last response: September 7, 2008 12:41 PM in Systems Share K33 September 6, 2008 6:46:28 PM Hi I have a home built machine which ran well for years then one day it would not boot. Motherboard ASUS A8N SLI Deluxe CPU AMD Athlon 64 X2 4200+ Skt939 2.2GHz 512KB The motherboard power light is on (on the board itself), but there is no life – no fans running nothing. I replaced the power unit – no change. I bought a second hand motherboard (same Model) motherboard power light (on ther board itself) comes on but machine is dead. I put an old single core CPU in - AMD Athlon 64 – Which I think is still good. No change. Anty suggestions please?

I suppose it could be a bad case switch K33 September 7, 2008 11:48:57 AM Thanks Proximon. I have now tried flashing the Power Up pins on the mobo with minimum stuff onboard. No joy.
