RAM slots not working after blown PSU

Flippy · 18 Dec 2020 at 15:06

I have a Gigabyte Aurous Gaming 5 with an overclocked 8700k and 4x 8GB Corsair LPX Memory.
I was using a Corsair TX750m and a Gigabyte 1080ti but then upgraded and to a Gigabyte GP-P850GM and a Gigabyte 3080 waterforce and a full water-cooling loop

Everything was running well for a few days and then well playing COD Warzone my PC suddenly switched off and wouldn't turn back on. I checked the plugs and the plug for my pc felt warm so had a look and it had blown the 5 amp fuse in the wall plug.

I drained the loop and played around and found the PSU wouldn't turn on, even when bridging the motherboard connector. Connected the corsair PSU and there was power again but had a long beep error and C1 on the board LED code. I removed all of the RAM but 1 (the closest to the CPU which is slot 4) and got through POST and booted into windows (with the 3080).
Put my 1080ti back in and played around with the RAM, I found that if anything is plugged into slots 1 and 3 then I would get the above error again. I reset my bios back to stock but that made no difference.

Does anyone have any suggestions that might fix this? I suspect the motherboard is damaged.

Did you move the cpu socket ,an ovetightend cooler can flex the motherboard socket, Check for any bent pins.

Thanks for the suggestion. I'll have a look but I don't believe I did

Reading this, did you try with the GPU out and RAM just in slots 1 / 3?

I'd try to get the system working with full RAM first? IGPU time!
