Hello, I would try to explain my situation as clearly as possible.
So today I was using my PC, just browsing the internet not even playing games to overheat my CPU or GPU, so they're out of the question, my PC suddenly just turned off. No fans running no display nothing, I would press the power button to turn it on but it won't. So I took it apart and tested the power supply by jump starting it using a wire between the green and black wire on the 24pin cable while having a fan attached to the power supply, I worked normally. I check even with a DMM, the yellow and red wires to check their voltages, they were 12V and 5V respectively, So i thought the PSU is fine.
Then I researched a bit and found out about the cmos battery, I changed it and it can now be powered on. But a new problem has arisen. Not all of my 4 DIMM slots are working at the same time together, I tested all of my 4 RAM sticks. First I checked each stick in the first DIMM slot and all worked. I even tested 1 stick on all DIMM slots and the slots were fine too. So the slots and sticks were not the issue.
Here, I have two ram sticks installed in a2 and b2 slots, as you can see they're working fine.
Here I have the other two sticks plugged into the other two ram slots, a1 and b1. They're working fine too.
But here's the issue, now I plug all of them, and only two work at a time.
So what can be the issue? The PC is really old, i7 3770k with Asrock z77 extreme4 and the 4 ram sticks are all the exact same, Gskill 4GB 1600Mhz 9-9-9-24 Latency. They worked fine until today.
Thanks.
