random crash to black screen and flashing coloured screen


Savage_Smithy

Recommended Posts

Hi, I just had a strange issue on my pc, I was watching a youtube video and suddenly one screen went black and the other just started flashing all random colours. I rebooted and the same thing happened again within minutes, and now of course I can't make it happen again on camera.

 

 Theres no way its an overheaing issue as It has a custom watercooling loop which is running extremely well, nothing ever gets above 50c. And it isnt leaking, which is the first thing i checked.

 

The specs are:

msi z77a g45

core i5 3570k

msi r9 290 reference card

16gb avexir core blue ram

corsair evo 540 250gb ssd

1tb wd carviar black storage drive

rm750 power supply.

custom watercooling loop.

 

It has been running fine in its current state for months and before that when it was just a cpu watercooling loop and air cooled graphics card it had been running for over a year without issue. All drivers are up to date.

 

No idea what the cause is but I know it shouldnt be doing it.

just to clarify the monitor that goes black is on the graphics card output wheras the one that flashes all manner of colours is on the integrated graphics output.

 

dont suppose any of you know a cause?

 

cheers,

Smithy :thumbsup:

I really hope it isnt that, as it would be PITA to change it and it has been working brilliantly since I rebuilt it. The problem just happened again for the first time since posting this.

 

and I can't really take the card out as im sure you can imagine...

So I'm asking hopefully if there is something else that could be doing this?

your running in crossfire mode right ? 

 

using the onboard gfx to boost the crossfire link to the secondary. 

and hence why your running dual screen on dual card. 

 

on the back of your card should be either two hdmi outs or a hdmi and a digital video interface port.

unplug the monitor thats set to the mainboard, and wire it to the DVI-secondary hdmi from the secondary card.

 

run the system and try replicate the graphical error ( if its the card this dual running of screens both will go blank black)

if the system goes stable for months on end, your main onboard gpu is the problem and possible its the drivers. 

we tend to try and use exact copys cards to run in dual-triple-quad gpu modes. ie you would run dual HD7770OC cards

and not a hd7770 stock and a 7770overclocked. ( the system auto drops to the lowest card and tahts the none oc version, so fact is the system underclocks your overclocked card)

 

your lucky you have onboard gpu, my P5Q pro oc board has NO onboard gpu, when my cards shoots out im knackered i have no graphical output at all.

 

so to recap its either disable the secondary card and run the onboard to replicate the error.

then install card and disable the onboard gpu ( if possible) and run for the card only to replicate the error.

if NO error comes for single running mode, your problem then lays internal driver software clashing. 

 

so also go and check the health status of the system in vista its preformance tools : advanced tools : system health report generator and also run preformance monitor .

check for red flags dealing with system driver files. its possible your leaving a error log and you just have to find it in the preformance manager/health report.

i'm only running a single dedicated gpu and onboard graphics seperately. In any case I seem to have sorted the issue now, i think it was a loose 24 pin connector not had the issue for nearly a week now after forcing the thing back into its socket. fingers crossed ahyway.

 

thanks for the suggestions guys

 

Smithy :thumbsup:
