So I've read about this issue a couple of times now but none of the threads seem to specifically deal with the issues I'm having. Here's my go:
First off, about my PC:
I bought my PC (System 1) back in 2014. The specs are as follows:
i7 4790
2x 8GB DDR3 Ram
msi GTX780 3GB (Twin Frozr)
128GB SSD
1000GB HDD
600W be quiet! Pure Power PSU (upgraded 1 1/2 years ago from a generic 570W PSU)
A couple of days ago, after almost 4 years of effortless service, my PC suddenly shutdown mid-session as if someone had yanked out the power cable. I checked everything, it was all well and good. When I tried to reboot it, all fans started to turn and fan LEDs lit up but stopped a split second after. There was no beeping or anything else.
I googled a bit and decided to disconnect my GPU from the PSU. Now my PC would boot up, but I couldn't get a signal through my onboard GPU, since the GTX780 was still plugged into it's PCIe slot. I removed the GPU alltogether and my PC would now behave normally, I could watch videos, play games and all that jazz via my Intel integrated graphics chip.
I also tried to reset the CMOS by removing the battery from my motherboard and reinstalling it after some time. - didn't yield quite the expected results.
Then I switched the PSU with the old PSU that I still had lying around. Sadly it showed the same exact behavior.
Today I got my hands on a friends system (System 2) for troubleshooting. I removed his GPU and plugged in the GTX780 and witnessed the same exact behavior as in System 1. [strike]*NOTE*: my GTX780 utilizes a 6-pin aswell as an 8-pin connector for power, while my friends 450W PSU in System 2 only brings one 8-pin connector to the table, so that could most certainly be the cause of my observation.[/strike] *EDIT* I've just ruled that out by using my old 570W PSU in System 2. Still same behavior.
Next I tried my friends GPU (some mid-ranged Radeon) in System 1. I removed both sticks of RAM, plugged in his GPU, plugged 1 stick of RAM back in and tried to boot. The fans and LEDs would now continue to work but now I can't get a signal on either of my monitors (one via DVI, the other via HDMI), even though everything is plugged in correctly and there was no such issue when doing the same with System 2.
I'm currently at loss as to how I should isolate the cause of the issue. It would appear as tho the GTX780 is at fault, since it produced the same symptoms in System 2. However, why does my friends GPU not work inside System 1 then?
Maybe someone can bring some insight into this madness.
Thank you all very much.
