motherboard malfunction?

[pnkmix]

went to a friend's house to fix his pc (high temps, lots of dust) disassembled and assembled everything w/o touching mobo,cpu and ram. After that i couldn't get the pc to post and spent a couple of hours troubleshooting only to find out the RAM wasn't working: when i used one stick of ram i had the pc booted properly with no issues. 10 minutes ago i came back to my house with my friends "malfunctioning" stick of ram (4gb ddr3) and decided to try it out and it worked just fine. I don't know what's the issue i'm guessing a problem with the mobo but not shure. Any insight on what the problem could be is greatly appreciated

Friend's mobo: P8H61-M LX3 R2.0

•  

Mobo in which i tested my friends ram stick: 960gm-vgs3

Forgot to mention that one of the two ram slots in my friend's mobo didn't work with any of the two different sticks of ram.

Thats what i thought but i just tested the stick in my mobo (960gm-vgs3) and it works just fine

Well, i think what happened is simple: your friend's mobo tried to dual-channel with his two sticks of ram, didn't work because one of the slots is broken, so the whole lot of ram wasn't working. Then when you inserted your single stick in the working slot, it didn't try to dual channel, so it worked just fine. When you tried with your friend's sticks in your pc, it obviously worked because the sticks were not the problem. solution: your friend has to change his mobo, not his ram.

Problem is, my friend only has 1 stick of 4gb ddr3 (kingston) so i don't think it had something to do with the dual channel setting

Another thing that bothers me is that it appears that the broken slot was always there. He bought a pre-built low budget pc and i'm starting to suspect that the first ram slot never worked. Nonetheless i find it weird that the ram stopped working because i didn't tinker with it at all when i was cleaning the pc
