Random Inconsistent Malfunctions

[Chipples]

This is a mostly brand new computer I built early this year. Bought all the parts separately, most of them brand new. I think only the monitor was manufacturer refurbished. For the most part it seems to work ok, but there are just lots of little things that worry me, like it's a ticking time bomb for failure.

 

Here are the specs:

Coolermaster Cosmos c700p Case

MSI x570 Gaming Pro Carbon Wifi Mobo

AMD Ryzen 7 3700x CPU

EVGA GTX 2080 FTW3 Graphics Card

Samsung NVME 970 Pro 1Tb SSD

Corsair h150i Pro AIO Liquid Cooler as an intake mounted on the front; stock exhaust fans on the rear and top.

Windows 10 Home OS

An optical disc drive, cause I don't believe those are obsolete just yet.

Seasonic 850w Prime Ultra Titanium PSU

Asus Rog pg27uq Monitor

 

 

I also have a Steelseries Arctis Pro with gamedac, which wouldn't really matter, except the gamedac happens to light up when the computer successfully boots, which brings me to my first issue.

 

On some occasions, my computer will just fail to post. No bios or anything. My keyboard and mouse light up, but not the gamedac, and it will just sit there forever unless I turn it off with the button, which happens pretty much instantly. no shut down sequence, delay, nothing. it just shuts off right away. This was a lot more consistent at one point soon after building it. I even remounted the cpu with a fresh coat of thermal paste cause the first time didn't go quite as smooth as I'd like. Same issue. After some google searches and lots of mashing the delete key, I finally got to the bios and found articles saying the preset cpu overclock msi provides with the mobo can cause this issue. I turn it off, all seems well...except it isn't quite well.

 

Before any of that happened, and still to this day, during the boot sequence the cpu debug light on the mobo will turn on for a minute, but eventually go away. Maybe this is normal, idk, but it makes me worry that the cpu or mobo are not fully functional or are on the brink of failure. And of course as I said, it does still on rare occasions fail to even boot, even one time several times in a row before it decided to work. It is quite rare now, but the fact it even might do that worries me.

 

I've also had weird issues with booting whenever my VR set is plugged in the graphics card. During the boot, I'll never get a picture until it gets to the windows login screen, and the lights on my peripherals and the gamedac will go on and off several times, as if something is failing and it's cycling through different modes or options or something to get to a working state.

 

Lastly is the monitor, aside from 2 or 3 dead pixels, which is sad for a manufacturer refurbished monitor, sometimes when the pc goes to sleep or turns off with the monitor still on, it will start flashing green, blue, and red. I think it's supposed to be some kind of factory mode thing, which it isn't in. Don't know why the hell it's doing that. Not as worrysome but it would be pretty annoying if my $1000 fricking dollar monitor suddenly went kaput. 

 

Oh, and the pc turned on by itself one time after I went to bed. That's about it.

Is the BIOS updated to the latest version?

Ah, yes I did update the bios right after finding that the OC preset was buggy, but I never tried using it again after that.
