Two days ago I built my first PC, the specs are :
Ryzen 5 2600
EVGA RTX 2060 XC ULTRA
Aorus X470 Gaming 5
stock cooler with no overclocking.
temps were fine, and everything worked until I installed Gigabyte's app center, which told me I needed to update the motherboard's BIOS from version F3 to F31 or something, it also updated on/off something, I can't remember the full name. It was fine until it started lagging out my computer, it got to about 50% complete until it said 'driver can't release to failure', I pressed ok, then uninstalled the application seeing as it was useless, by doing this I also accidentally uninstalled RGB fusion that came with my motherboard, after reinstalling this, I tried to reconfigure my settings, when I changed a color, my entire computer froze with the spinning cursor also frozen, I then pressed and held the power button on my PC until it turned off, (my case has no reset switch) but weirdly the RGB on my motherboard was still on, so I turned it back on again, and all the fans ramped up to 100%, the computer rebooted once or twice without posting, then the red DRAM light comes on and alternated to the CPU light for a fraction of a second then back to the DRAM one.
All the fans work, it just sits there with fans at 100% not posting.
I have tried removing one stick of RAM and switching slots
I have tried removing the CMOS battery and putting it back
I have tried removing the GPU and putting it back. Since my case has no reset button, I have tried to short out the reset switch pins on the motherboard with a screwdriver so I could try and access the backup bios but weirdly when doing this my GPU fans get very loud and spin very fast but nothing happens. I've checked that all the power supply cables are plugged into the motherboard correctly and they're all fine.
As a first time builder I would appreciate all the help I can get
and preferably I wouldn't like to have to RMA any parts after 2 days of use :(
Thank you for taking your time to help,
