PC monitor keeps going black but the tower still runs

hello there, my desktop PC keeps randomly having the monitor go black with a message coming up saying no signal however this is not all. if i am watching a video it will loop the sound also, so its just turns into an elongated humming noise. does anyone know what to do? i have taken it to a technician he said he took it apart and rebuilt it and left it on for around 2-3 days and this didn't happen. over the course of 10 days he tested what he could and still did'nt know. i got the pc back around 3-4 days ago and it's only just started happening again. i have 7 fans and a big cpu heatsink so im not sure its temperature.

the computer remains on and humming normalyl throughout all of this. i have tried different hdmi cables also and no difference.

what info would you guys need?

Have you tried installing a different OS and try using it?

My grandma had this issue and I switched her from XP to Win7 and it works fine ever since.

Re: PC monitor keeps going black but the tower still runs

Ok, let's hear it - full specs, and what have you tried so far?

This sounds like something worng with the GPU, have you tried reinstalling/updating drivers, or if you have a spare card try switching?

Re: PC monitor keeps going black but the tower still runs

hey there. i built the computer myself.

i am using an MSI X99 sli plus motherboard

16gb ddr4 crucial ballistix ram 4 sticks at 4gb each

intel core i7 5820k 3.30 ghz cpu

64 bit windows 8.1

EVGA geforce gtx 970 graphics card

EVGA super nova 850w psu

be quiet! shadow rock2 heatsink

one 140mm mill fan at the top facia back sitting intaking

one 120mm fan at the bottom facia front sitting intaking

two 120mm fans at the front facia bottom sitting intaking

one 120mm fan at the back facia top sitting exhuasting

plus the heatsink fan and the 2 gpu fans.

as far as im aware all my drivers are up to date.

technician has swapped out graphics cards, psu's ram, as have i. i've changed the monitor connector cable, started it on safe mode basiclly a lot of things. i'm wondering whether it's just dust, as when i got it back from the technicians it worked fine without any hitch for 4 days then started getting flirty :s would it be wise to use an air duster on the inside of it?


UPDATE
__________

it's started making black/white lines flash horizontally across the bottom of the monitor just before it goes black now. literally for a split second. however it sometimes recovers after it goes black and then proceeds on normally (as if nothing is wrong) for however long.

Re: PC monitor keeps going black but the tower still runs

4 days of dust should not be enough to cause problems unless your house is very dusty? In any case you can use an air duster but be careful as sometimes they end up just forcing the dust further into small gaps etc.

You said you've tried swapping out various components - any not ruled out yet? It still sounds like a GPU issue to me - is the problem identical with a different GPU?

Re: PC monitor keeps going black but the tower still runs

i wouldn't say its super dusty the computer at least works for as time...albeit nondescript.

apparently the techy tried it with a different card and everything etc was fine. although he had it for 10 days and didn't see it do anything of what i'm saying.

It's probably the GPU then, do you have a spare you can try?
