Question My motherboard kills any ram i put?

[itsJIMBO]

So yesterday I finally bought a gpu and finished my build. But instead of enjoying games I'm now having the most inexplicable problem I've ever seen.

basically i wanted to swap HDDs last night so I turned my PC off, did that but when i turned it on again it just didn't post at all, every fan spun but GPU LED didn't turn on and there was no display. I thought it's the gpu at first but it kept doing the same even when i took it off, I even tested it on my friend's pc and it's fine.

So i went through a whole process of elimination and came to the conclusion that the motherboard is broken.

I Tried my ram sticks on another pc and it didn't post, so the rams were broken, I tested a different ram stick on my pc and it actually turned on. but after i turned it off and on again it did the same thing.

so now I'm left conflicted whether it's my psu or motherboard that are at fault. The PSU is new, it's been a month since I bought it and it's 600w so it's not like it doesn't provide enough power.

What are the complete specs for this system (make/model of ALL installed components)?

When you installed the GPU and made the changes noted in your post, was the system disconnected from all power sources?

Did you connect/disconnect anything while the system was powered on?

as for the changes, I didn't really disconnect the power cable from the PSU but it was switched off and all i did is change a SATA data cable from one drive to the other, didn't touch another thing

That is a very low quality PSU.

Will the system display anything with the GPU removed?

well it was either that or a fire hazard psu, but i researched it and it seemed fine. And no if i remove the gpu nothing shows up.

My rams are dead, and either the motherboard or the psu are killing any new one i put in.

also I'd like to point out that i had ram issues prior to buying the PSU and they were manageable, but now it doesn't matter what ram i put in, it turns on, i can use windows normally, but once i shut it down it will not post again.

Sounds like the motherboard is the likely culprit. Given its age, not surprising.
