troubleshooting PC cant start past BIOS

[VIPGamez]

Recently I built myself a new PC and I couldn't start anything past the BIOS screen. Later I realized that I had to download new BIOS for the Ryzen 5000 chip to work and everything worked like a charm. The only problem was that I bought a case that was too small and today I received my bigger one (and an AIO) and moved the system to the new case and installed the AIO. BIOS loads, every component shows up in "board explorer" but after that - can't boot windows. I tried a fresh install but when I plug in a USB drive with windows and boot from it, it gets stuck at a purple screen. If I wait 10 minutes, the normal windows istaller shows up and I can select language and click install and then it gets permanently stuck at the loading screen (I waited for 2 hours and nothing moved). I restarted the system about 100 times to no avail. I tried to hard restart it by stopping the power and pressing the power button to remove all leftover power. I tried reseating the RAM, unplugging and plugging most cables and making sure the rest are plugged in properly (my cpu cable is unreachable and cant be plugged out but i have made sure it is all the way in.

I tried flashing the newest BIOS - same stuff. Every fan spins, every component lights up, every component shows up in BIOS and yet - it can't boot. The only things I changed were the CPU cooler and the PC case and I applied thermal paste and everything is connected where it should be.

The specs of the system are:

CPU - Ryzen 5 5600X

AIO - Lian Li Gallahad 240mm with the thermal paste that comes with it

Mobo - MSI B550 Mag Tomahawk with newest BIOS

GPU - Palit Gaming Pro RTX 3070 in the uppermost PCI-e slot

PSU - EVGA 850G (850 Watt 80+ Gold)

RAM - 2x16GB Patriot 3600MHz 18CL in the 2nd and 4th slots

Case - Lian Li Lancool II

NVMe SSD - 500GB Samsung 970 Evo

SATA SSDs - 512GB Silicon Power A55

240GB Phillips SSD

HDD - 1 TB Seagate

 

I also checked the integrity of the NVMe using the tool in the BIOS and it said "No errors found" (Windows is installed on it)

Also, I do have a version of Windows on the Phillips SSD too if that is a problem let me know, but I wasn't a problem last time.

I honestly have no idea what to do and it feels like I've tried everything. The only thing I haven't tried is to clear CMOS (read that in another forum but idk how to do it).

I also tried lauching without CPU boost and the XMP profile and no change. I also tried turning it off for a while and letting the black screen load for a while - nothing.

 

Basically, no matter what I do - permanent black screen when I try to launch Windows and long purple screen when I boot from a USB followed by a permanent loading screen.

If it’s the exact same system with no changes that worked earlier  it shouldn’t be an issue.  Therefore  Something has changed.  Finding out what that is may be the key here.

 

one thing I might try is shorting the cmos pins.  This will set the motherboard to default bios values so if something odd was set in bios it will go away.  This also does things like removing any overclock and resetting memory to base speed but we can worry about that stuff anter the thing is working.

As I said - the only thing that's changed is the case and the AIO.

Also, could you help me a bit more with those CMOS pins? I have no idea where they are and how to short them.

Then it should work, which it doesn’t, so something else has also changed

Long shot, but are you sure that there was no extra motherboard standoff already installed in the case?

Could be a short.

I took out the battery on the motherboard for about 1 minute and tried again - still nothing.

As for standoffs, I am using an ATX board so there are no extra standoffs.

And once again, the things that have changed are the case fans, the case and the cpu cooler.

And that you took every part out and put it back in so every connection.  I suggest reseating everything and make sure each part got put back in the right place.
