GTX 970 does not post after powercut

Specs:

970A-G46 MB

AMD FX8120 CPU

16GB DDR3 1600 RAM (4x4GB Ballistix Sport) 

MSI GTX 970 GPU

EVGA 650 G2 PSU

Samsung 850 EVO SSD Boot Drive

WD Caviar 1TB HDD

LG E2242C Monitor

Windows 7 OS

 

The other night my son's computer powered off by itself in what I assume was a power cut (a local business reported one the same night). Since then the computer has been unable to post to either the LG monitor or TV I have connected to it via HDMI. After some troubleshooting (swapping RAM around, resetting the CMOS) I used an older GPU (Radeon HD 7750) and it was able to successfully POST and boot to the TV, although not to the monitor.

 

From here I'm a bit lost. Any advice?

For one, check the monitor. If neither the Radeon or the NVIDIA GPU can display anything on it, the display might be dead. Secondly, find a friend or a local PC-shop to test the NVIDIA GPU.

 

If the display is dead, that could have killed the NVIDIA GPU when it went kaputt or vice versa.

Probably a Voltage spike in the grid that triggered the power in your area to be shut off for safety,

Such spikes can kill electronics,including computers and their components,

I will not be surprised if a voltage spike fried the GPU and monitor.

Next time connect valuable electronics to a power surge protected extension cord.

The PC and monitor are both connected to a surge protected extension cord. 

It could be a fake one,or just bad at doing it's job,either way it failed,

Either way those companies that make such products usually provide warranty to anything connected to them in case the the product fails to protect them from a power surge.

I would pursue such warranty if the company who made it provides one.

It's idiotic to jump to the conclusion that it was a power-surge from mains that was the issue and to claim that the surge-protected cable failed as a fact. You don't know that. Besides, it would most likely have killed other things too.

 

No, the more likely conclusion is simply that either the GPU died or the display died and took the other device with it. It's not that uncommon to see that e.g. a display's power-supply has died and sent a spike through the display-cable to a GPU as well.

It's really strange if what you say happens right after a power outage and it was fine before it...

The OP doesn't say there was a power-outage in the house, the OP says the PC shut off. Why did it shut off? Because the GPU died.

I did: he just simply assumed it was a power-cut because a local business reported them having a powercut. He didn't say he did have a powercut, he only assumes so.

That's how power cuts work...

You lose power,your neighbor lose power too.

You wake-up in the morning with most electronics in the house powered off.

 

Please don't try to play games here,that guy needs help not word games.

OP didn't say anything about the neighbours, OP didn't say anything about anything else in the house having powered off. OP said that the PC shut off and assumed it was because of power, that's all. If the display died, and killed the GPU with it, then that would definitely shut the PC off without the problem ever having anything to do with mains-power.

I already offered him help, if you'd bother to look up the thread.

@Vishera assuming is not the same as being sure.

 

Was someone else at home? Or did your son see the lights go out as well? Ask your neighbors if they noticed anything. A power cut usually impacts more then just two buildings.

 

My best guess is that either the monitor or the GPU died. Did you try the GPU again? Try hooking up something else to the monitor?(something not to expensive, could die as well)

OP does state that they tried another GPU with the display and got no image, which is why I think the display is a goner.

I know, but the GPU might be dead as well. Might even be the cause of the dead display. By trying the old one again you can rule this out and just get a new screen.

I already told the OP to have a friend or a local PC-store or similar to check the GPU. Just have to wait for OP to reply something.

True.

That's important,once it's confirmed then we can proceed.

I think we need to wait for the power outage to be confirmed before we ignore it.

I've just been messaging my son. He tells me that he was at the computer (playing Hearthstone) when it died. The lights didn't go out in his room. I only suspected a power cut as a local business reported on too (so couldn't take card payments). I was only able to test the old GPU via HDMI, which worked (PC booted up on the TV). The monitor only has a DVI input so I don't think I can test it with any other hardware in the house (I don't even have a VGA cable to test the MB without a GPU). Hopefully testing the new GPU with a different monitor will shed some light on things. I'll try and source a DVI to VGA or HDMI cable/converter to test the monitor.

Update time. A friend of mine came over with some cables. The 970 didn't post from DVI or HDMI, we didn't have a VGA cable to test that output. We tested the Radeon too, although this time there wasnt any output (same for when we used a different PCI slot). My friend agreed to test the 970 in his rig and it works! So I'm wondering if it's the MOBO or PSU. I'm going to try a new CMOS battery just in case, and then take it to a repair shop if necessary as I don't have a spare MOBO and PSU laying around. I'm not sure if there was a power surge now, none of my neighbours noticed anything and when I spoke to the shop owner they said their power had gone down due to the wiring in their building being faulty.

Another update. I replaced the cmos battery and tested the Radeon card, which worked with the TV via HDMI. I then reseated the 970 and that worked fine with the monitor and TV as well! My son was happily listening to YouTube whilst playing MTG Arena earlier today when the pc crashed. He told me that the screen went black but the computer was still on. He rebooted it but again, no screen. At this stage I'm assuming it may be something to do with the 970 drivers, or that the card isn't getting enough power somehow. Any thoughts? If I can get it up and running again I'll have a look at event viewer or BSV if it's installed.
