After 8 months of stable computing I come home one day and my computer won't turn on (no fans or beeps).
After considerable troubleshooting I found that if I have the outermost PCI-E connector (furthest from the display ports) on the video card plugged in is what's causing my computer not to turn on. But if I connect either of the two 6+2 pin cables to the other PCI-E connector the computer turns on although I haven't tested if the card actually works but its fans do spin. This is all with the card seated in the motherboard. I'm using the motherboard DVI input currently.
It's weird that it failed when idle or maybe the PSU spiked it? I don't run any apps when at work or overnight. A look at the windows update history shows nothing during that time.
Since video cards are very expensive, I was wondering if there's anything else I can look into or maybe test the PSU? I have a multimeter and roughly 10 fingers and 10 toes.
