In desperate need of help! Potential dead gpu

post #1 of 21
Thread Starter 
Ok, i started to hear a very faint whining sound in my case everytime i'd load up a game and it went away when i went to the desktop so i assumed it was my gpu. The computer was premade and this sound has been there all along but today i thought i'd do something about it. So i just took a dry cloth and wiped off whatever dust was on my gpu and now whenever i turn on my PC i get NO signal whatsoever. I'm not sure if the mobo is dead or it's just the gpu. I thought it was the monitor but i hooked it up to my laptop via hdmi and it worked fine so it's my desktop. What can i possibly do? I took out the gpu and put it back in, moved ram over to different slots, took out mobo battery to reset bios but i don't even see the "gigabyte" screen anymore that i'd first see when starting up the comp that let me go into the bios. The monitor is just always black and can NEVER get a signal. If i have to RMA the gpu, i'd have to send the whole comp back(just a note)

Well the whine that you heard before you tried to clean your computer was most likely just coil whine which is not uncommon on modern GPUs and PSUs and is nothing to worry about. I'm not sure what you could've done when you tried to dust off your GPU but I don't think that the whine meant that your GPU or PSU was about to fail before so I wouldn't worry too much yet. First off I would get a can of compressed air and remove the GPU and anything else you touched with the cloth and blow it off and then start trying to replace things with any spare components if you have any to try and isolate the problem. Hopefully someone more experienced than me will come along and give you some more detailed troubleshooting information but I wouldn't worry to much just yet.

Did you keep yourself grounded while cleaning inside your case?

Well judging on the fact that I don't know what that means, maybe not...do you mean did i keep myself de statified? Does touching a lot of metal before working inside my comp count?

Generally speaking, yes.

Ok, well i made sure to do that, but if you could tell me, of what i specified, is there any discernible way to tell if my entire mobo is dead and not just my gpu?

When i turn it on the fans all turn on, everything sounds normal for the most part, and yet no signal ever goes to the monitor. Monitor always says check cables, i even switched to vga on the gpu and monitor instead of hdmi like i normally use and still no signal and i already tested the monitor on my laptop and that worked fine, so it's definitely not the monitor

I don't mean to offend or insult your intelligence but check all the power cables, specifically the 2 six pin cables on your GTX 560. I can't say for sure but if the fans are spinning up and are connected to your motherboard rather than the PSU then I would be very surprised if you killed your motherboard. This is probably something easily fixed so just look over your entire system for problems and walk through everything you did when you dusted it and look for problems.

Oh and for future reference make sure you are grounded (touch bare metal of your case or PSU before touching anything else like you did) and also use compressed air for something like this rather than a cloth.

One of the first things i did was check the power cables to the gpu, took them out, put them back in, all fans spinning like normal(including the gpu's fan)
