The issue started yesterday I woke up and when I went to turn my pc on it wouldn't post at all all the fans in the pc including the case fans , CPU fans and GPU fans spin at 100% when I press the power button , the RGB on the motherboard and on the fans are no longer working either , I have tested the PSU in another pc and that one booted up fine with it. I'm starting to think it's the motherboard as it won't light up at all anymore ect my specs are as follows 

 

Aorus B550 elite V2 

Ryzen 7 5700x 

Gigabyte 700watt PSU

Gigabyte RTX 4060 

32GB Corsair 3200 ram

Corsair m.2 SSD 

Crucial SATA SSD 

 

Any help would be greatly appreciated as I use my pc to communicate with people and due to it being down I'm very isolated.

Welcome to the forums!
That sucks. It could well be the mobo. Strong work on testing the PSU
Have you tried booting with all peripherals disconnected? Also clear CMOS and try waiting a few minutes (actually look at a clock for this) to eliminate the possibility of it just doing memory training.

Yes I have tried unplugging everything that wasn't essential with no difference I cleared the CMOS and also put a new CMOS battery in without a change I was only able to get it to post and boot up for 5 minutes before it shut off again and wouldn't come back on the one thing I did notice was the time and date was completely wrong but haven't been able to get it to turn on properly since

Yeah the CMOS battery powers the part that saves all the bios settings, including system time / date

 

Power on the pc without the cmos battery, and bios will detect all settings are reset, temporarily boot the pc and note how long the pc stays on.

 

My first thought is your CPU is really hot, and shutting down to protect itself from literally burning out the chips inside.

 

Have you put thermal paste on the CPU, and is it spread out after putting on the cooler?

How bad is e-waste?  Listen to that Joe Rogan episode.

Windows 11 will just force business to "recycle" "obscolete" hardware.  Microsoft definitely isn't bothered by this at all, and seems to want hardware produced just a few years ago to be considered obsolete.  They have also not shown any interest nor has any other company in a similar financial position, to help increase tech recycling whatsoever.  Windows 12 might be cloud-based and be a monthly or yearly fee.

 

Software suggestions


Just get f.lux [Link removed due to forum rules] so your screen isn't bright white at night, a golden orange in place of stark 6500K bluish white.

released in 2008 and still being improved.

 

Dark Reader addon for webpages.  Pick any color you want for both background and text (background and foreground page elements).  Enable the preview mode on desktop for Firefox and Chrome addon, by clicking the dark reader addon settings, Choose dev tools amd click preview mode.

 

NoScript or EFF's privacy badger addons can block many scripts and websites that would load and track you, possibly halving page load time!

 

F-droid is a place to install open-source software for android, Antennapod, RethinkDNS, Fennec which is Firefox with about:config, lots of performance and other changes available, mozilla KB has a huge database of what most of the settings do.  Most software in the repository only requires Android 5 and 6!

 

I recommend firewall apps (blocks apps) and dns filters (redirect all dns requests on android, to your choice of dns, even if overridden).  RethinkDNS is my pick and I set it to use pi-hole, installed inside Ubuntu/Debian, which is inside Virtualbox, until I go to a website, nothing at all connects to any other server.  I also use NextDNS.io to do the same when away from home wi-fi or even cellular!  I can even tether from cellular to any device sharing via wi-fi, and block anything with dns set to NextDNS, regardless if the device allows changing dns.  This style of network filtration is being overridden by software updates on some devices, forcing a backup dns provuder, such as google dns, when built in dns requests are not connecting.  Without a complete firewall setup, dns redirection itself is no longer always effective.
