PC suddenly turned off

Hello everyone, Was in a middle of a game and suddenly the PC turned off on its own and it wouldn't start again. Pressing the power button just made a 'rel...

Thanks yasamoka for the reassurance. I tried the ram swap again no result. I even added two different PCI-E cables from the PSU (modular) to the card and it does the same.

So i am running out of options, fast!...and as you yasamoka Supreme commander shouldn't have heated the thing :(

When everything was working fine, the monitor was plugged in on the card not on the motherboard. So after it stopped working "on that faithful day" and when i removed the PCI-E cables that's when i changed the plug to the mobo's output. And I remember though to install lucidMVP i had to enable the onboard one as well from BIOS.

How do I use the above code to post some images?

You need to upload the pic to a image hosting site like http://www.imgur.com and exchange the URL and name.

What I meant is, what happens when you do the following:

1) Card is plugged in, PCI-E cables plugged in, monitor connected to motherboard output
2) Card is plugged in, PCI-E cables not plugged in, monitor connected to motherboard output
3) Card is removed, monitor connected to motherboard output
4) Card is plugged in, PCI-E cables plugged in, monitor / TV connected to another output (HDMI)

I also need to confirm whether VSync was running or not. You might want to go into the game when running on onboard and check whether VSync was enabled or not. This is VERY important to know.

1) Card is plugged in, PCI-E cables plugged in, monitor connected to motherboard output
- Nothing, doesn't boot

2) Card is plugged in, PCI-E cables not plugged in, monitor connected to motherboard output
- Works fine (even the card's fans turn)

3) Card is removed, monitor connected to motherboard output
-Works fine

4) Card is plugged in, PCI-E cables plugged in, monitor / TV connected to another output (HDMI)
Well the screen has only D-SUB and DVI - when i was using the card i had an adapter from DVI to SUB to use with D-SUB cable. So wouldn't know since don't HDMI input on the monitor.

And i checked the game option Vsync was on - how bad is that?

I don't think the card is the issue here.

You see, when I burnt my VRM, I plugged in my second 7970, and placed the burnt one in the second slot. Windows still booted fine and showed the second card (with missing details in GPU-Z). The card doesn't output itself, but the working card output fine.

Later on, I did the same, outputs fine, but Windows gave a BSoD due to not being able to communicate with the second (burnt) card.

VSync on means the games was running peanuts, it shouldn't have heated the card AT ALL, only rendering 60FPS. So that's good news. If VSync was off, and the game was uncapped, you'd see FPS soar, and that would have heated up things (though not necessarily to the point of overheating!).

Your system is unable to boot because the card is plugged in, that's the exact issue. The system doesn't communicate with the card until further on in the boot process, I believe, so even if the card was defective, you'd still receive normal output from the motherboard.

You really really need to try the card in another PC? Do you have any other PC available? (Make sure it has a capable PSU!).

EDIT: when you remove the PCI-E cables, the card doesn't even turn on. It's like it doesn't exist. That might explain something, I guess.

EDIT2: I see the fan turns on with PCI-E cables unplugged. That's new to me.

Well when the card is plugged in and you hit the power button you feel as if a security mechanism forbids the system from powering on. It doesn't even get to detect anything. Now am not sure if this is perhaps the vga is asking too much power which xfx stops everything or xfx got damaged?...

so I guess bottom line is to try it out on a different pc!- which think of it I don't have one lying around? Any ideas?

Check your PM.

dude no need for all these test when this thing happens its 90% the card has a short circuit somewhere probably in one of the vrm's mosfets so when you plug in pcie connector and turn on the psu detects the short circuit as an overload on the 12v rail and shuts down immediatly nothing to do with the mobo ram or anything else, the only solution is replacing the fried component, this happens randomly and doesn't necessarly mean the card overheated these are electronic components which can die because of a manufacturing defect or for no reason at all.

edhunter

Sadly, that is one of the most plausible explanations. I guess I had the unlucky number!

shant

just send it to warranty, even if you found out whats wrong (which is 90% overheating issue) you're not allowed to fiddle with it anyway else bye bye warranty

Im building my own pc and im afraid the same problem will occur with me.

That is the theory, and it's most likely to be true if all else fails. Since we can't directly determine whether there is a short circuit or not (without voiding the warranty), then we have to troubleshoot everything else.

So no, there is a need for all these tests.

Try connecting 1 PCIE power. If it doesn't power on (Even without a POST) It's a graphics card problem.

This does not mean that the graphics card manufacturer is bad. This means that your luck is so bad that out of millions of units, yours was faulty.

I didn't faced this problem but I said Im afraid to face like this problem in future after completing my new pc since i need to bring my gpu from amazon

This is a risk you'll have to take, unfortunately. Amazon are nice enough that an RMA is mostly only an issue of time and effort, and not one of money.

Aha so whats the solution if the video card I want is not found in Lebanon?

yasamoka

You order from Amazon :P

Or stick to consoles :P

Find the Official Dealer and request it from him/her

Official dealer? Wahahahaha.

Well...the jury is out...defective Card!

Defective card? My motherboard and PSU almost quit LOL.

I was AFRAID!
