Hi, I have a problem with my graphic card, yesterday after turning my PC on, after 10 minutes of normal running, my screen turned black with information "No Signal". I restarted PC, then fans of graphic card goes crazy, they are running at 100% speed and there is no signal, I cant hear any beeps and I dont see any damages. I cleaned everything from dust, tried changing ports but nothing helps... My warranty runs out 2 weeks ago so I cant request RMA, if you have any ideas how can I fix it please help :(

PC Spec:

SilentiumPC Deus M1 650W
Gigabyte GeForce GTX770 WindForce
Intel Core i5-3570K
MSI Z77A-GD55

You really should check the GPU's temperatures. The hotter they get, the faster the fans spin, and the GPU can only reach the highest temps before heat throttling then finally forcing itself off to prevent further damage. This has happened to me on my last graphics card, I reached dangerously high temperatures, then finally one day it broke down due to constantly running at high temps. I learnt that the hard way.

Can you please tell me what peak temps that you reach? It may not be a heat problem - it can be anything, but most commonly it's caused by heat.

Dont think its because of temperatures, when I turn my PC on, fans already are running at 100% and I cant see anything but "No Signal" information on my screen, I think my card is dead :(
 
Remove and reseat the graphics card. Your gpu fans spin up to speed during boot up but then should slow back down. Its hung up trying to boot which is why the gpu fans keep spinning full speed. Could be bad gpu or motherboard/cpu. I would try to remove and reinstall the video card then go from there. If you have onboard videocard with that intel cpu go into your bios and turn it on then plug your monitor cable into it. If everything boots fine then you know the rest of your system is fine and its just your video that has gone bad possibly.

Fans spinning at 100% implies the GPU is not detected and POST didn't finish. Do you have a speaker in your P.C? You should hear three beeps. 2 long, 1 short.

If you said the GPU shutoff without warning there's a good chance a voltage regulator blew. Hopefully this isn't the case.

I would recommend resetting your CMOS (take out motherboard battery and all power connections for 10 minutes), remove one stick of RAM, and clean off the GPU and PCI slot with alcohol or cleaner of your choice.

If you can get the GPU to boot, put your other RAM back in and go on with your day. Good luck.

Your motherboard also two PCI-E slots available. It's very possible that a slot can be damaged. Try the other one.

Ok, here's what i'v done:

Cleaned PCI slots
Cleaned GPU
Removed CMOS battery like you said


Now it seems like fans are running at normal speed, not at 100% like before, but there is still "No Signal" information on my screen so I cant do anything on that card, cant hear any beeps or anything like that.

Not sure if that matters but now im using Intel's card and everything running fine on it.

Quickedit:

Also, Im not sure how it works but when I connect my monitor to Intel's card with GTX 770 on PCI Slot not connected to any monitors, I cant see anything on my screen (and without GTX 770 in slot it works normally) so it looks like PC is detecting GTX 770 but there is no signal (IM NOT SURE IF IT WORKS LIKE THAT)

It seems progress may have been made but we're not there yet.

Can you go into the BIOS and double check that your Video is set to the PCI-E? Do you have your monitor plugged into the GPU and NOT your motherboard (I know it sounds ridiculous and I don't want to belittle you, but it does happen).

If all else fails, please try the bottom PCI-E slot.

I changed some options of integrated graphic card in BIOS and its WORKING! ITS ALIVE ! ! ! !

Weird think is that when all it happened I didnt touch any options so how can I prevent similar situations in future?

It's hard to say at this point but I think the solution was resetting the CMOS completely to refresh the systems BIOS, then switching over to your GPU to seal the deal.

My guess is a power surge, heat, or a G shock triggered your system to become unstable and corrupt your CMOS. Watch temps closely for the next while. Plug your computer directly into the wall (No power-bar)

Good luck and good to hear it's working.
