Monitor randomly goes black for a second every so often

Hey there!

So I just built a custom computer and just replaced the monitor cause I thought it was the issue, but it didn't help. My entire screen will randomly go black for a second every so often. I'm thinking it might be the hdmi or the graphics card?

Here's my setup:

Operating System
Microsoft Windows 7 Ultimate 64-bit SP1
CPU
Intel Core i5 3570K @ 3.40GHz
Ivy Bridge 22nm Technology
RAM
8.00 GB Dual-Channel DDR3 @ 656MHz (9-9-9-24)
Motherboard
Gigabyte Technology Co., Ltd. Z77X-UD3H (Intel Core i5-3570K CPU @ 3.40GHz)
Graphics
IPS277 (1920x1080@60Hz)
NVIDIA GeForce GTX 670
Hard Drives
233GB Samsung SSD 840 Series ATA Device (SSD)
Optical Drives
No optical disk drives detected
Audio
High Definition Audio Device

I've got all the latest drivers and such (or so I think...)

Any ideas?

  4. Its your overclock. if you leave your card overclocked, ALL of your digital signals will flicker. Mine does the same, turn off the overclock in CCC, the throttling the card does in the bios for voltages and clocks causes this

    also, flash will cause flickering too

    i have a 6870 (5870 cypress rebadge)

    try using ONLY your VGA signal - unplug the DVI - bet it stops EVEN WITH your overclocks - something about SOME radeon cards VGA + DVI - im running 3 monitors off one card, an active VGA on display port - a HDMI > DVI converter > and my DVI signal, both my HDMI and DVI will flicker, my DP to VGA will not, because its being picked up as an analog signal

    Hmmm, could be either. Try using JUST the TV (hdmi output) and see if it flickers, if it flickers you know for sure its the HDMI port on the card or cable. If it only flickers when your using both digital outputs, it could be a driver conflict.

    Im not an Nvidia user by any means, because CUDA is no use to me (if it was id still use Radeon)

  8. i found this problem it turned out to be mains interference from something being turned off or on locally. my wife's PC above bedroom causes my Htpc to go blank for a second or two when she turns it on or shuts it down. and i had an electric fire did it too when the thermostat turned it off and on i moved the fire further away from the tv and all was ok.

    I too encounter the same problem... the display flicker to black if certain switch around the house gets turn off or on. I am unsure what to do since switching power outlet doesn't solve the problem. Half my system is old (PSU, Mobo, RAM) & half of it is new (VGA, HDD, monitor)... could it be due to having an old PSU & Mobo? I have google the problem for some time... a lot of results this first time I seen a reply that mention a connection with power system for the rest of the house and so far no solutions.

    The new vga is also different from my old card, it draws power directly from the mobo with no cable connecting to the PSU. It's an PCI-Express 3 card & my mobo is PCI-Express 2. I am really afraid that it is damaging the system if it doesn't stop.

    VGA: MSI Geforce GTX 750 ti
    Mobo: Gigabyte P67A-UD3-B3 (more than 3 years old)
    PSU: Seasonic X series 760W (more than 3 years old)

    It is probably a capacitor that needs replaced, about $10.00 at a Radio Shack (Providing you can solder). I've replaced 2 before on separate monitors, one Dell, One Optiquest. Fairly easy,..I followed a YouTube video instructions, worked on both. A little late, but there you go.

    seems like a good idea to instantly get a new monitor instead of looking for the solution first.

    I found the solution to my black out problem... it is the HDMI cable... more correctly the HDMI, the problem went away once I switch back to VGA.

  15. I'm 99.99% sure it isn't the monitor. I had the same problem for years with my last PC running Vista OS. Replaced the PC with a new one running Windows 10, but kept the LG monitor that would flash to black. Connected using same cable as before. No more flash to black observed.

  18. My guess is whats happening is something is interfering with the hdmi signal, and so it has to do the HDCP handshake at times, when it does the screen blanks untill its sorted itself out
