I'm having a problem with a build.
MSI 790GX-G65 Winki Edition
AMD Phenom II X4 945 3.0Ghz
MSI GTS250 1Gb Twin Frozr OC
OCZ DDR3 PC3 8500 7.7.7 1.8V (2X 1Gb kit)
i-Cute 700W PSU
+3.3V=28A +5V=28A +12V1=20A +12V2=20A -12V=0.8A +5Vsb=2.0A
I have it breadboarded so there's no short issue. When I power up with just the CPU and HSF installed I get 3 long beep code after 10 seconds, the HSF also starts of very fast and then slows down to an idle speed in about 5 seconds but doesn't stop. If I install the RAM I get no beep codes and no signal from the onboard GPU. Now I know this sounds like RAM error but I had an ASUS mobo before I picked up the G65 and was suffering the exact same problem, no beeps when the ram was installed (2GB Crucial DDR2 800Mhz). I tried that RAM in another PC, it's working fine. The 4 pin 12V rail is plugged into the mobo.
This leaves me with the CPU and PSU, the only two parts from the original build I'm reusing to try to get the G65 to POST. My first question is, does the PSU's split 12V rail have enough power to run my setup, could it be causing this problem? Second question, is my CPU bricked? All these components are new, nothing pulled from an old running PC. I've given the CPU a visual inspection, no aparent damage, no scorching, melting or bent/broken pins.
