|This system is about 4 years old.|
Specs from Newegg:
PSU: XCLIO GOODPOWER 500W 500W ATX SLI Certified CrossFire Ready Active PFC Power Supply
CPU: AMD Athlon 64 X2 3600+ Brisbane 1.9GHz
RAM: G.SKILL 1GB (2 x 512MB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
Motherboard: BIOSTAR TFORCE 550 AM2 NVIDIA nForce 550
GPU: EVGA 256-P2-N624-AR GeForce 7900GS 256MB 256-bit GDDR3 PCI Express x16 SLI Support
System shut off on its own a few days ago. Light on the back of the PSU blinks when the power is plugged into the motherboard, but is solid when hooked up to my PSU tester. Voltages all within normal ranges on the PSU tester. Tried a new motherboard (BIOSTAR TA790XE AM2+/AM3 AMD 790X - I know, AM2 processor in AM2+ board, but it's supposed to be fine) today - same issue: a blinking light on the PSU, no power to the system (no lights, no beeps, nothing). Put my old motherboard back in, ensuring everything was tight and such - still no dice. Tried without RAM, tried with the sticks in every possible configuration - still nothing. CPU still has a good amount of Arctic Silver on it, but I didn't see what the temp reading was right before the system crashed.
Not sure what the issue could be here. Could the PSU test normal with my tester, but still be shot? It appears that the motherboard isn't the issue, so the only things I can think of are:
1. CPU dead
2. RAM dead
3. PSU dead
Would appreciate any help here, as I'm completely stumped and don't want to start shelling out cash for components I may not need...
