Help! Where have I gone wrong? Motherboard/CPU replacement.

Natjtbxx · 29 Dec 2024 at 17:41

I’ve just replaced the CPU and motherboard in my son’s PC. Never done this before. Followed all the instructions really carefully. Pretty sure I reconnected every cable in the right place (took photos before just in case) It powers up (lights and fan work on motherboard) but that’s it. No signal to monitors. Doesn’t seem to connect to keyboard either (usually lights up)
Where do I even start with troubleshooting? I’m regretting starting now.

MSI pro H610M-E motherboard
Intel core i5 12400F processor
GeForce RTX 4060 graphics card (reinstalled in the new motherboard)
Reinstalled previous memory too
Monitor is plugged into graphics card

Upgraded from i5 6th gen

How do I update bios? Was I supposed to do this beforehand?

Was the parts new or 2nd hand?

CPU seems to be supported from the first bios so they should work together

CPU and motherboard were brand new

something daft already!! said:
Does it have a separate graphics card or built into the motherboard? If a separate card, did you plug the monitor into it? What are the system specs? Can you take a photo of the motherboard in situ and upload it?

I’ve posted spec above but this is motherboard insitu

What does the EZ debug LED show?

Reset the CMOS (manual here, instructions below, use a screwdriver tip to CAREFULLY bridge the pins https://www.msi.com/Motherboard/PRO-H610M-E-DDR4/support#manual)
Try with only 1 stick of RAM in different slots.
Hard drives/SSDs are connected? (shouldn't make a difference but still..)

LED is orange. RAM issue?

Natjtbxx · 29 Dec 2024 at 20:36

Thank you!!! It was the RAM! Took one stick out and I’m in. Now what?

Try putting the stick back in, maybe wasn't seated properly or bit of dirt on connector. If it doesn't work then likely to be that stick.

Yeah it doesn’t like that stick.

New issue is that it isn’t detecting any boot device?

Where are the drives? Are they SATA drives on cables, or maybe there were some M.2 drives (small cards) in slots on the previous motherboard?

Yeah hard drive is SATA. BIOS is picking it up.

Mite not be the ram it mite be the pin affecting the channel , did you check to see if it was bent ?

I’ve checked again this morning. Does look like it might be bent. I can’t see very well though because it’s so tiny! Tried to get a better picture. Does this look bent to you?
If so is it fixable?

Boot priority been checked?

Yes set to boot from hard drive first

re: RAM.
Try the working/non working sticks on their own in all slots, should show you if it’s a RAM or mobo/CPU pin issue.

Tried both sticks in one slot and it will boot to BIOS. The other slot won’t boot with either stick. So definitely seems to be an issue with that one slot

Could be UEFI Vs Legacy mode on boot drive config?

went right through the BIOS settings and boot mode is UEFI or CSM. Is CSM legacy mode? If so should I try booting with that? That’s one thing I’ve not done yet.

Update and a new issue!
When I got to trying to sort the bent pin it looked like part was missing so I cut my losses and got a new motherboard.
Now its stuck on the green light which is a boot error. Computer won’t boot at all, not even to bios. I’ve checked the cables are properly connected, tried different SATA ports, tried another cable. Still the same. I’m out of ideas so came back here to see if anyone had any ideas.

Natjtbxx · 2025-01-12T17:54:55+0000

I’ve managed to get the bios screen up now but it just keeps cycling back to Bios and isn’t booting from the hard drive. Hard drive is top priority in settings

Natjtbxx · 2025-01-12T18:11:40+0000

I’m in! I forgot about legacy mode. That’s all it needed.

Natjtbxx · 2025-01-12T20:39:15+0000

Yeah it’s booted windows from the hard drive in legacy mode and we’re all set up now. Only issue is it’s not recognising the second monitor which is plugged to the hdmi port in the motherboard. So in the grand scale of things now it’s minor but just need to figure that one out.

The i5-12400F series doesn't have an integrated graphics adapter in - the F suffix denotes no graphics. So onboard/motherboard graphics ports won't work. Is there another free socket on the graphics card? You can get DisplayPort to HDMI cables or adapters as it's a passive conversion (just a different pin selection from the socket).

Thanks! Just found out the same from google about the F suffix so going to get a new cable because there’s only one hdmi port in the graphics card
