I am a newbie in this forum, so go easy on me!
 
My machine configuration is as follows:
 
* GA-965P-S3
* E2200 + Thermaltake Ultra 120
* GEIL 2x1GB PC6400
* FORTRON FSP AX400
* eVGA 8500GT
 
I used to run the E2200 @ 300 x 10 and DDR2 @ 800 4-4-4-12
 
The voltages were as follows:
 
DDR2: +0.3v
FSB: +0.1v
(G)MCH: +0.1v
Processor: 1.38v
 
This configuration ran fine without any problems for more than 6 months.
 
But since yesterday my motherboard stopped POST'ing!!
When I power on my machine, the CPU Fan and System Fan come up and stay On.
The power button lights up and stays on. But I hear no beeps or do not see any display.
 
I tried the following things:
 
1. Swapped RAM with one CORSAIR PC6400 module
2. Swapped RAM with one A-DATA PC6400 module
3. Tested PSU with PSU tester and Multimeter as well (It is working fine).
4. When I boot without RAM, motherboard beeps like crazy
5. If I remove the Video Card and boot, I get no beeps.
6. Disconnected the power, pressed power button a couple of times, removed the battery, reset the CMOS... Still no use.
 
I am at my wits end. Can somebody tell me if there is anything else I can try?
