System specs:
- Processor: Intel i7-9700KF
- Motherboard: MSI MAG Z390 TOMAHAWK
- RAM: 8 GB x 2, DDR4-3200, ADATA XPG D41 RGB
- PSU: EVGA 850W B5
- GPU: GeForce RTX 2080 SUPER ASUS DUAL EVO OC
- SSD: 1 TB ADATA SU750 SSD
This setup was working for 1 year before it suddenly gave out while playing a game. Any attempts at trying to unplug/plug the PSU and then switch it back on only caused the system to 'flash' on for near milliseconds, then die. Here's the current situation I am at right now: when I connect the PSU to only the motherboard, CPU, SSD, and peripherals, it will power-on (i.e. the LEDs flash, the fans run, and it will continue to stay this way without powering-off.) However, when I slot in my GPU into the PCI-E slot and then provide the 2x8 pin power to it, the system will do the same 'flash' on for a few milliseconds and then die again. Interestingly, if I disconnect and slot out the GPU and attempt to turn on the system again, the system will not power-on. It will not respond to the power-switch at all. The only way to have it power-on again is to re-jump the BIOS (I manually take out the CMOS battery, wait a few seconds, and then put it back in). After resetting the CMOS battery, the system will successfully power-on again (without the GPU slotted in). Of note, when I only slot in my GPU (without providing the 2x8 power pins) and attempt to switch on the system, it will not power-up. When I remove the unpowered GPU from the PCI-E slot and then again attempt to switch on the system, it will not power-on. I must do the CMOS battery reset again to have it switch on again.
I've attempted to connect my monitor to the onboard graphics, but the monitor will not detect it when it powers-on. This makes me think it might be a motherboard issue but I come to you all for more wisdom on this.
Thanks ahead of time.
