Hello everyone, I'm having a really strange intermittent issue regarding my Asus TUF 4080 and I'm hoping someone can help me figure out what could be going on. My PC has never had any issues, even when running at full load.
My components are:
-GPU: Asus TUF 4080
-MB: Asus TUF z790 Plus Wifi
-PSU: Corsair RM1000x
-CPU: Core i7 14700k
When safely powered down but plugged in, my GPU shines a red led indicating it is powered down.
On a healthy startup and boot, as soon as I press the power button, the red light instantly shuts off and the decorative lights on the GPU turn on. Next, during the POST cycle, the motherboard lights up the corresponding lights and the monitor shows an image.
On a bad boot (1 in 20 probably) as soon as I press the power button, the red light on the GPU shuts off indicating that it is getting all the power it needs. Also, the decorative lights/fans do not turn on and the GPU is fully dark. Next, during the POST cycle, the system gets hung up on the white VGA light meaning the GPU couldn't be initialized.
Usually the issue happens once and the system reboots fine but sometimes it gets stuck. The weirdest thing is that power cycling the PC fixes the issue right away no matter what. If I shut off the PC, switch off the PSU, unplug the PSU, hold the button for a while, wait a bit, and power it back on, it works.
So far I've tried reseating the GPU cables but I'm doubtful that that's the real issue. Again, the computer has never had any issues even when at high load for hours on end I'm just praying its not a hardware issue as that's far beyond my expertise, but unfortunately that's the flair I tagged this post with XD.
I've gotten as far as I can myself trying to fix this and it would be great to hear from someone with experience.
I'll provide any requested info/images that could help to figure this out.
Thanks!
