Hi there, I've just built a PC, all components are new except the case, DVD drive and one hard drive. It was up and running for about an hour last night, but while running updates I noticed a burning smell and it suddenly shut down.

 

Now, when I turn it on, the monitor says "No display" and sits on standby. All the components are powering up fine (visibly) - all the fans come on and the LEDs are working.

 

What I've done: I've tried a different GPU, different monitor cable and a different monitor but with the same issue each time. I also checked the thermal paste on the cooler and reinstalled it, checking it was locked down tight.

 

Components:

 

Motherboard: Asus Z170M-PLUS LGA1151

 

CPU: Intel Core i5-6600 3.30GHz

 

Aftermarket cooler: SilenX EFZ-120HA5

 

GPU: MSI Geforce GTX 1070

 

PSU: Corsair RM750X

 

RAM: Corsair 16GB (2x8) DDR4 3000Mhz

 

Storage: 500GB Samsung 850 EVO, 1TB HDD

 

OS: Windows 7 Home Premium

 

Obviously I'm disappointed and worried that something expensive has cooked itself, it seems the logical suspects are the CPU or the motherboard, but I'm not sure how to proceed. I'd really appreciate some help - it's my first build myself, I painstakingly followed guides and instructions and this aside everything ran fine to begin with.

Check that CPU socket pins are not bent.

I just double checked, thanks but the pins are fine.

Start checking the obvious (cables, CPU contacts), try monitor on a different computer you know is working, ddoes GeForce have a built in fan? Have you configured the gpu in bios? Maybe the new gpu is creating more heat than your fans can filter out?

Yeah the GPU has a fan, its drivers are all installed and updated but I can't access bios now so I can't even see what temperature things are running at. It's strange because if the GPU was overheating it would make sense that my PC was at least run for a while, as before the issue it had been running on and off for an hour updating.

 

I've tried switching cables with the spares that came with the PSU but to no effect.

I'm starting to think you have a process running that is putting high demand on the gpu causing it to crash i.e computer game, 4k video. Also try rolling back the drivers for your gpu and see if that fixes anything, may be a corrupt update file

I'm not sure, it was a completely fresh install so the only thing running at the time was an optional Windows update that was downloading. Unfortunately I can't do anything with it until I've resolved the display issue first.

The other thing I should have mentioned is you could have very well fried your card completely. I'd double check before hand (haven't done a video card repair in forever) but remove your video card and power up the pc (it should switch to on board video) and see if it boots and everything works, then you'll know the video card may have bit the biscuit on that one. IMPORTANT: if it does boot, go into BIOS and check all your critical settings!
