Motherboard: gigabyte GA-P35-DS3R CPU
CPU: Q6600
Testing some vintage components I found on eBay. It came with four RAM modules, plus an old GPU. The power supply I'm using is a Corsair CX650. I've reset the CPU and tested each RAM stick one by one. It powers on briefly—CPU fan kicks in, phase LEDs flash—then shuts off again, restarting the cycle. This behavior hasn't happened before, so I'm not sure what's causing it. Any suggestions?
I faced a similar problem with my RAM. I let it sit for about 20 minutes and the PC started in BIOS setup. After around 30 minutes, I checked again—if it worked then. Otherwise, it might be the motherboard, CPU, or RAM itself. Your PSU seems fine and probably not the issue. Since you tested each RAM separately, it’s unlikely the RAM is faulty. You could replace the motherboard and test the CPU there; if that fails, your CPU is likely the problem.
It seems the initial two RAM modules didn’t work properly. Using a stick from the third slot—closest to the CPU—seems to have resolved the problem. Because this board is old, I’m considering cleaning the slots to see if that fixes it, but I wanted to share this approach in case it helps others.
