I'll be using my computer and suddenly one of the following will happen
a)screen goes black , the monitor will say that there is no video input, however I can still hear audio playing in the background (music playing from a different hdd)
b)screen goes black,the monitor will say that there is no video input and there will be no audio in the background (when there should be)
c) Video will freeze and in the background a repeating beep will be heard (through speakers) until i hard reset my pc.

Issue is totally random, can occur within 10 minutes of booting the pc or after 5-10 days since last incident.It has occured when i had tabs in Mozilla open,(Facebook and news articles and listening to music), has occured while playing videogames such as Dishonored 2, Heroes of the storm, World of warcraft, Diablo 3,Overwatch,The witcher 3.
Has never occured while i burn dvds/blu rays.Has never occured while i reencode video files using Handbrake.Has never occured while playing Metal Gear Solid 5 or older generation games.(I got a large library on Steam).
(clean )Installing latest Nvidia drivers and using past version drivers has not solved anything.
Using Nvidia Experience settings for the games has not solved anything.
I have my tv connected to the pc as well when issue happens no video on secondary port as well.

I had the exact same issue with my previous setup of (windows 7 x64 bit,Intel i5 , 8 gb ram, same amount of ssd/hdds , thermaltake PSU 730w ,SAME GPU.)

From what i ve written above i am guessing that there has to be some kind of issue with my GPU.My question is that if there is an issue with the GPU, how come when i use FurMark (for 12+hours) nothing happens,3DMark completes succesfully, Unigine’s Valley also completes successfully ,OCCT also passes for several hours, MemTest86 ran for 12+ hours (I had to make sure that the Ram works ok first).All the temperatures of all parts is at normal prices at all times while the stress tests are working.I do not have a secondary gpu or the money to buy a similar speccs GPU atm.
If anybody has ANY ideas on what more to test before i decide to replace this gpu with a much cheaper (sadly ) one or similar experiences feel free to write.


Specs:
OS: Windows 10 Version 1703
GPU: MSI Geforce GTX 970 (About 2 years old)
Mobo: Gigabyte Z170-Gaming K3 (6 months old)
CPU: Intel i7 6700K @4ghz (6 months old)
RAM: 2 x 8Gb DDR4 (6 months old)
PSU: XFX TS 650W Less than 2 months old

SSD: Samsung 840PRO 250 GB (About 2 years old)
HDD2 (Downloads): Western Digital 500gb (About 4 years old) 100%health
HDD3 (Games): Werstern Digital 2tb (About 2 years old) 100%health
HDD4 (Storage): Western Digital 3 tb (About 2 years old) 99%health
 
Is anything overclocked? If it is, set it all to stock speeds. Having issue now, had issue before with the same video card, I would test another card in your system, test your card in another system. You have a bunch of drives in the system also, test it with just the single boot drive connected, get rid of any variables aside from the core system. Test with one RAM stick at a time.

I have crosschecked the Rams - issue persisted , have removed all hdds was left only with ssd - within 10 mins on playing Witcher 3 on high details pc would freeze.Remove secondary dvi (for tv ) as well, issue while playing witcher 3 persisted. I downloaded MSI afterburner software downlocked core speed by 250 Mhz and manually set up fan speed to 80% at all times- been playing Witcher 3 with no freezes for 2 + hours. Today i checked with Heroes of the Storm as well, My theory is that there is something wrong with the cooling (passive or active) of my gpu. Hence overheating while gaming - as gpu would not set fan speed high enough due to load not being 100% and whereas when stresstesting the gpu , the gpu would keep fan speed as close to 100% and as a result it wouldnt fail. I am going to keep testing it for couple more days and if everything works out i will replace the GPU thermal paste.
