Question PC rarely gets to POST and crashes if it does ?

[4ktv]

I have encountered issues since the beginning of this build in part because of my GPU. The main PCI slot on the MB hasn't worked from day one and yes I tried a total of 4 GPU's in it. Each time resulted in the white GPU light being on and the system refusing to start at all.

What's happened now though is that after installing an update the system wouldn't post the first 10 or so tries. Waited until the next day and then got into windows. It then blue screened and that's when I tried removing power for long periods of time before attempting another boot. I've been in recovery mode and tried using the auto repair, but the system would crash in moments. I tried system restore and then it crashed in the middle of it while the motherboard had the white CPU light come on.

Most boot attempts result in the system having the fans at 100% or the GPU light coming on or the CPU light coming on or getting though the process but then crashing to a white cpu light. Does this point to a faulty power supply, CPU failure, motherboard failure or is this some kind of software issue. Right now I am at a loss and could use an outside prospective as to what could be the cause or what my next steps should be.

Thanks in advance for any advice.

You have any warranty left?

Not on the GPU. Would need to look it up for the other parts.

I would RMA the power supply and mobo.

You Should've Got It Replaced On Day One If Its Under Warranty

Didn't think one PCI slot was worth ripping the CPU out for. Thought it might have been a firmware issue.

If I RMA the motherboard I'll risk damaging the CPU.

But you can just take out the CPU before you RMA it. If you are careful, the CPU won't be damaged.

I have never had to remove a CPU before to fix a system so I'll likely watch a few videos before doing that.

Do you know what BIOS version your motherboard is on? Did it say 'Ryzen 5000 ready' on the box?

Update motherboard BIOS!

Updated the BIOS and now the white RAM light comes on. It refuses to post at all.

Was your RAM on your motherboards QVL? Try seating just one RAM stick, (and change slots) to see if it will post.

Reflashed the BIOS. The system posted. Then booted into windows for a few seconds before crashing and the white CPU light came on.

Nothing I have tried has changed the situation. At most it will boot and then blue screen due to a white CPU light coming on the motherboard. I don't think it's the power supply as if I get into bios it will freeze then turn the white CPU light on. I have tested the power connections and believe this is a motherboard issue and possibly a CPU issue.

I don't know if MSI will honor an RMA request or not considering my experience is they will blame everything under the sun but themselves. Does anyone have advice for how I should go about doing RMA with the motherboard or should I try to see if Amazon will handle it?
