I moved 180 miles saturday and set up my ~6 year old PC, gift to me, yesterday. Today while I was it presumably crashes and I return to it spinning up and down the PC fan every 3~5 seconds, trying to reset. I killed the power.
I poked around with it, checked component connections, blew out the insides with can of air. Fan hasn't tried to run since, Power button is unresponsive. Eventually I tear it apart.
Everything after this point i'm a bit shakey on, I've built a computer with a friend before and I'm not intimidated by these things, but I'm also a bit unsure of myself with as I go through the following steps for the first time. I looked through this No POST troubleshooting checklist to get this far.
Currently, I've got the Mobo and PSU torn out and connected (pictured). The 24 pin JPWR1, the 4 pin JPWR2, and the CPUFAN are the only things plugged in. I connect PWR SW pins with a screwdriver and nothing happens.
I dropped my SSD and Wireless card into an old 2007 tower and it runs. I couldn't get the mobo to post when I connected it to that 305W power supply, but that was a janky job because I didn't want to tear everything apart in the second tower.
I don't have a speaker to troubleshoot error codes, nor do I know where to get one nearby. Can order. I do have a multimeter. I suspect its my PSU. Please advice.
