GTX 970 Monitor Turns Off and On -- Even During POST

[Forgotten031511]

Hey All,

Need some help! PC Specs and Issues Below:

CPU: i5-4690K
RAM: 16GB
GPU: Gigabyte GTX 970 G1 Windforce (DVI Connection)
SSD: Samsung EVO

The issue was just that my monitor would turn on and off, consistently. I tried another monitor and got it working. Then the same problem started with that monitor. So I then changed the DVI Port I was using on the GTX 970, seemed to start working again. Now, nothing works with the DVI connections.

I put the GTX 970 into another computer that has a DisplayPort Monitor and it worked great, no issues and was in video editing like a champ.

So, I then put the GTX 970 back into my i5-4690K PC and tried a difference PCI slot on the MB as suggested in other threads. Rebooted and SAME PROBLEM...on, off, on, off, on, off...any now it appears my PC is slower than a Celeron back in the day with Safe Mode. Rebooting back into Normal Mode it appears to still be running super slow, but still has the on, off, on, off, on, off, issue.

With the on, off, on, off, on, off issue with the monitor all the way back in POST; I don't think it's a driver issue and believe it's a faulty card issue?

Any ideas?

What's the brand and model of the motherboard and monitor?

 

[Forgotten031511]

Motherboard: GIGABYTE G1 Gaming GA-Z97X-Gaming 5 (rev. 1.0) LGA 1150 Intel Z97 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

Monitor is a ViewSonic, older model, 22"

***MB updated!

Gigabyte Support didn't really help, just offered a RMA Warranty Link. Hoping to find the quick fix?

UPDATE: When I leave the PC on for longer periods of time, I notice the on, off, on, off, on, off pauses and the screen stays normal for a few seconds...then goes back to the blinking.

What is the speed of the system like when using only the Intel HD Graphics 4600 integrated graphics on the CPU?

 

[Forgotten031511]

Good question, I have not checked!

Though, I do see my SSD is very full (through the blinking) and I am working on clearing out files to see if that helps the speed. I will certainly update soon with how the HD Graphics 4600 work.

 

[Forgotten031511]

I have cleaned out 30 GB of storage on the SSD and the speed issue seems to be resolved. Once the last few updates are done (been a while since I turn that PC on due to the monitor issues) I will reboot and try the HD Graphics 4600.

Same issue when I use the HD Graphics 4600!

CPU, MB, RAM?

 

[Forgotten031511]

Running mdsched.exe in extended mode to check for memory errors. After that, which is more likely MB or CPU?

You could try running the Intel Processor Diagnostic Tool:

THANKS! After the long memory test (let it go overnight) I'll check that next. Should narrow down the RAM, MB, or CPU as the problem.

 

[Forgotten031511]

Memory Test: PASS
Intel CPU Test: PASS

Other suggested programs to run and test?

 

[Forgotten031511]

OK, so after MORE testing I found the problem to be fairly random...didn't know this before as I never let it go long enough cause the on, off, on, off, screen drove me BONKERS!

So I did some more testing. I brought over a Display Port Monitor to use and test. At FIRST it seemed to have the same problems. So I rebooted into Safe Mode and rebooted back into Normal Windows. Since then...everything works!

Thoughts?

I am even able to run Heaven at 2560x1440 with 40-50 FPS without problem for extended periods of time (currently 2-3 min). Going to run Heaven now for an hour, see if it holds.

Have you scanned for any corrupted system files? Open a Windows PowerShell (Run as Administrator) and run the following command:

sfc /scannow

It will verify if there are any system file integrity violations.
