Question Advice needed on PC boot looping ?

[Thomas5589]

I changed thermal paste yesterday and went through a lot of problems with black screen, therefore taking out the CMOS battery for a reset. After 5 minutes I replaced the CMOS battery and now the PC is booting on/off all the time, no BIOS, nothing, I have to unplug power cable to stop this loop.

Now I am trying to figure out the different options as I have a bit of money spare, thinking about an upgrade.

Current setup :
- Asrock B450 Steel Legend.
- CPU : Ryzen 5 - 5500.

Possible options :
1. I try to fix the issue but I have no idea how.

2. I upgrade my pc but that would cost me some $500 or so.
- intel core ultra 7.
- Gigabyte B860M Aorus Elite.

3. I buy an mac Mini 4 and move my current hard drives to NAS.

My use case :
- Video editing and encoding.
- Photo editing.
- No gaming.

Please let me know what would make sense ?

Hi it seems like the motherboard is power cycling which it will do when the CMOS is reset as you have done. It can take a few minutes to finish cycling. It will shut off and turn on again on it own, as it is resetting the motherboard configuration to default, then POST and boot into Windows . The motherboard is retraining the RAM and is checking all hardware to prepare it for POST and booting into the OS. Give it a few minutes to complete power cycling as it needs time to finish, then it should POST and boot automatically. I hope this might help. Please advise. Thank you. Also please advise if you see the CPU RAM or VGA LED lights on the board show red when it is starting and if it still will not boot. If green you are good to go.

Thank you so much, I figured out the issue was due to RAM that I seated again.
Nevertheless now it is booting and running without any shut off BUT ... I have a black screen.
I plugged DVI cable to Motherboard and GPU but doesn't change anything.
If anyone could help me, I don't know what to do.
Thank you !
