Windows 7: is my computer dead?

is my computer dead?

Situation:
When i try to turn on my computer nothing happens. I don't see any LED turned on, no fan noise, no biib.

Spec:
Ocz vertex 3 256 gb. boot drive
Intel Core i7-2600 k @ 4.4 ghz /w Noctua NH-D14
gigabyte GA-Z68X-UD4-B3 (rev. 1.0)
Radeon HD 6950 2GB
corsair vengeance 1600 Mhz cl8

History:
I got a thread in General discussion (Computer doesn't start cant get into bios or advanced start up setting)
Where i was trying several things since i couldn't get into the bios nor advanced boot, got suggested to reset my CMOS and tried the method by unplugging the battery, didn't work then i tried the Jumper pins, and saw on the internet that i can use some metal object to connect the pins and i used a screwdriver. after that I haven't seen any signal from my computer.

If you read through my general discussion debate then you get a good picture of the situation.

2 days ago my brother was trying to Turn on his PC and it was'nt doing anything... all i did was i changed the Power Cord and it's working again. That's possible that your Power Cord has died so try another one if you have a spare or just take one of the LCD/Monitor etc.

It is getting power.
It was working before i did the jumper method. no one touched it so i suppose it is working but not 100% sure.. will try another one if i can find one.
the wall switch is on & working since one TV is also in the same switch and working fine.
No I haven't tried another PSU yet, since i don't have any other in my reach, need to buy one in order to test another one.

check the PSU, most I know have a dedicated on-off switch (although I work with oldish stuff, don't know about newer ones). If it is turned off even if it receives power from the wall it won't work (duh!).

This detail caused annoyance more than once, to me at least.

I noticed in the other thread you started you were asked for your specs. We still don't have your specs. Use Speccy to get them.
Speccy - System Information - Free Download
Install them using User CP at the top of the page. That way they will follow your every post.
Did you follow any of the suggestions in the other thread and what were they and the results.
It's very hard to help with out specs and jumping around from thread to thread for the same computer with the same problem. The right hand doesn't know what the left hand is doing. I would recommend using one thread and not jumping all over the Forum for the same problem with the same computer.

I posted this in your other thread, but I'll add it here too.
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.

He posted his specs in the OP.
And running speccy on a computer that refuses to turn on is... complex.

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.

Thanks.
