MSI z97 Gaming 5 Motherboard build, not starting

[Marquizel]

I was cleaning out my computer because the CPU kept thermal throttling so I dissassembled and reassembled my computer. While I was cleaning I noticed the motherboard screws on the bottom were a little lose. I tightened them a little and then everything seemed to be fine. I got my computer put back together and turned it on. It was running about 10 degrees cooler and I was all good. It started updating Steam as happens every days just about. And then it froze at 100% and I just thought nothing of it and watched a youtube video while I waited. Then suddenly my computer reset itself. I dont mean it restarted through windows. It did a hard reset and I thought that wasnt normal. But it booted back up pretty much just fine but it seemed really slow to load my wallpaper and background tasks. I looked at the computer and saw the little MSI indicator light flashing blue as the computer once again shut off. And now it is in a repeating cycle of on and off and wont even get into the bios. I tried unplugging and replugging everything, reseating the heatsink on the CPU, reinstalling the graphics card and it still has the same issue. I thought it was related to cooling at first but I dont know where. Because when I let it cool down longer it seems to run longer before it resets itself again. I'm really not sure where to go from here, it appears to be a problem with the motherboard itself but Im not sure and dont have anything I could swap it out with to make sure. Please help.

Did you re-seat the processor when you had the cooler off?

Yes, I made sure there were no bent pins too as Ive had that problem before as well.

I would try re-flashing the BIOS. I was reading about similar problems in MSI gaming laptops, related to the BIOS getting spontaneously corrupted.

Worth a try anyway.

Does your PSU have green letters or silver letters? I have been doing a ton of research and the "green letter" Corsair units are not good apparently.

The other "blue light" posts that I read were mostly tracked down to an issue with the 24-pin or 20+4-pin main power connection.

I am pretty sure its Green, Im using an H440 and this isnt a modular psu so I cant pull it out with out disassembling whole computer. But its still strange since I've been using this for 4 years now and its just now having problems after cleaning it.

I checked out that link and tried swapping my RAM out to an old 4GB stick and it didnt help

How far did you strip it down? Did you have the board out? Was the 24-pin off and back on?

Okay so I took out the PSU all the way its a CX750, green label. I pulled the graphics card and still have the PSU out. I plugged in the PSU to only the Mobo and CPU power cables with one hard drive running and it seemed to boot up just fine for a few minutes again

I would try a known-good PSU if available

I don't have another full sized PSU available right now but I did get it running with both hard drives with the PSU outside of the case with no GFX card and its been running very slowly for a while now, not much has loaded Im starting to question if the hard drive is finally almost dead, its been having problems recently but I dont know what to do with nearly 2TB of files I need.

If the drive is not actually dead (yet) you should STOP using it and use another machine to transfer the files off of it. You might want to prioritize the order you get them off in as well.

EDIT: Did you ever get a boot device LED on your board? You probably should have if the primary HDD is failing.

So I have honestly no idea why but I just put everything back together and now its perfectly fine, I was just about to give up too and now it all runs smoothly and faster than before. I think I may have broken one of the cables to the Graphics card to the PSU because I switched those out and that seemed to fix the problem, Thanks for your help anyways!
