Can't get past bios

[YusufUSA]

Hello everyone. I built a PC about 8 months ago.

I have a 

Ryzen 2700x

Msi gaming x 1660 ti

32 GB 3200 Vengeance lpx ddr4 ram

Gigabyte aorus b450 motherboard

Corsair 850w psu

Until last week everything was fine. I was watching YouTube and downloading some files when a got a "blue screen of death" it restarted and since then has not been able to get past bios. I can enter bios but when I save and exit it loads the eagle logo and then blue screens again. I took the motherboard to the retailer and they tested it and said they can enter windows.

I have taken out the battery and cleared bios. Tried bother RAM sticks single channel. Unplugged everything and I still cannot get past the eagle logo with a blue screen of death. I tried a fresh install of windows and I still get the blue screen of death. What could be possibly causing this?

What did the bsod say ?

Any debug LEDs ?

how were you able to reinstall windows without the machine going past the bios

I haven't been able to. I tried by using a windows boot USB. I chose that as the boot I. Bios but after I save and exit it freezes on the windows logo for a few seconds then blue screens.

Honestly I don't know how to check that. I know where they are but never knew how to read them.

try running the system with only a single ram stick. try each stick by itself in the machine to see if it gets any father

It could possibly be a failing boot drive (e.g. your HDD / SSD).

You could try atleast the GPU and RAM in another machine easily if you have a friend nearby to see if those are faulty.

I was thinking the same. But with the virus going around nobody wants guests. I'm picking up some new ram tomorrow and I'll try that. Worst case is I have more RAM.

I that that too so I took out the SSD and formatted it. Nothing works. I either get a page fault error or system thread exception not handled.

My bet is there is an error in the Memory for some reason.  Check and see if any fault codes come up on your mobo. Try booting with one stick of RAM, or try even swapping the ones you have.  Memory issues seem to so silly and random.  I'm sure they aren't, but swapping them usually works IMO.  Don't ask me why though. haha.

Purchased and installed new ddr4 memory. Still cannot install windows 10. I get to the bios logo and then it tried to install windows (I see the windows logo) but then bsod...system thread exception not handled and then it reboots and repeats doing this. Can it be the graphics card? Or the CPU? PSU? These are all that I have left to eliminate. Not sure what to do.

I think the GPU is probably the least likely to be faulty, not sure though. CPU or PSU seems the more likely culprit.

Thanks. That's what I thought so I'm taking the PC to the retailer because they are all still under warranty.

That's great! Hope you get your system working soon

Took my PC to a have diagnosis done and they said it was the memory. They were 2 brand new modules. So I replaced them started up the PC and right after bios I got a kmode thread exception not handled. The bsod seems to bounce between kmode thread exception not handled and system thread exception not handled. I called him and he said bring it in again today. Is there anything I can say to him? Could it be the Mobo? Like one of the slots? What else can cause these two codes? Any advice. The PC sad is empty. I can't even boot from USB to install windows without one of these bsods.
