Normally, even when there are only two pins, the plastic jumper will still be there, only connected to one pin. Inside the plastic shell is a metal contact that shorts whatever two pins its connected to. Shorting the two pins with a metal object is the same as putting the jumper on and then taking it back off again. If the power supply is unplugged, and any residual power drained, nothing bad should happen when you short the pins. Pressing the power button with the supply unplugged will drain off any residual power. The only other thing to watch out for is a static discharge when using a screwdriver or other similar device. If you fingers are touching the metal shaft a static discharge can happen and damage the motherboard. That's why the jumpers have a non conductive shell. CMOS chips are especially susceptible to static discharge damage. It sounds like, even though proper procedures were followed that something got damaged on the motherboard.
I don't doubt that something has happened, I can only find 3 possibilities.
1. The PSU not working
2. the Motherboard not working
3. the power botton is disconnected from the motherboard.
for 1. is it possible to damage an 850 w corsair 80+ through a static discharge? If not then i don't think that it is likely that the PSU is totally dead. Don't know if an damaged PSU allows you to boot up into the startup screen before shutting off again, if it can then possibly the PSU is damaged. (2 years warranty which still is valid can solve that problem)
2. If somehow I've managed to damage my motherboard meanwhile proper procedures were followed am i able to ask for a new board from the manufacturer? Or will i have to buy a new one myself?
3. Since the issue went from boot up problem to a dead computer by connecting the jumper pins with a screwdriver, i find it very unlikely that this is the issue.
an clear answer on these three will give me a clear picture and make it easier to see where i am currently standing in the situation.
