I am facing this problem regularly and dont know what to do about it. Sometimnes there is no problem and goes on for weeks.
Sometimes It happens so frequently that while working all of sudden Monitor goes Off. Sometimes it doesnt come back and I have to turn off PC from Power Supply box of the PC. Again to restart I have to turn on switch from Power Supply Box and sometimes it turns on the monitor or sometimes it dosent respond. I tried the same on my LCD TV and repeated the same problem.

I dont understand what is the problem. While typing this message it blinked twice but automatically regained the display on itself.

Can anybody help me

Given ’s report and ’s suggestion to isolate the display, the behavior (display losing image while the PC stays powered) most often narrows the cause to either the graphics subsystem (driver or GPU hardware) or the PC’s power delivery to the GPU. The following diagnostic sequence is ordered from least-invasive to more-invasive so the problem can be isolated efficiently.

Recommended diagnostic sequence:

  • Swap video cable and port (use a different HDMI/DVI/VGA lead and a different GPU/motherboard port).
  • Note monitor LED/onscreen state when the screen goes black: LED off (monitor losing power) vs LED on with “no signal” (video output lost).
  • Boot to BIOS/UEFI and leave it running: if flicker happens in BIOS, software/drivers are unlikely — hardware or PSU is the prime suspect.
  • Boot a Live USB Linux or Windows Safe Mode to remove normal graphics drivers from the equation; persistence there points to hardware.
  • Check Windows Event Viewer for entries like display-driver crashes or kernel-power events; these logs help decide between driver hangs and power faults.

When hardware checks are next:

  • Reseat the GPU and all PCIe power connectors, and inspect GPU and motherboard for bulging/leaking capacitors or dusty/heavily-worn fan bearings.
  • Monitor GPU temperatures and fan speeds (HWMonitor/GPU-Z). Overheating or a stalled fan can cause the card to stop outputting.
  • If available, test the machine with a known-good PSU or try the GPU in another working system; swapping PSU or GPU is the fastest way to confirm which part is failing.

Software and final steps:

  • Perform a clean driver uninstall in Safe Mode (Display Driver Uninstaller) and reinstall a stable driver from the GPU vendor. Consider chipset driver and BIOS updates from the motherboard vendor only if the issue remains after hardware checks.
  • If the problem persists after these steps, replacement of the PSU or GPU (in that order for power-related symptoms) or service under warranty is the prudent next step.

Caution: power down and unplug before touching internal parts and ground against static.

you need to try the monitor on another computer to determine if its the monitor or the video device in the computer

I checked another monitor on the same PC and had the same problems.

yes, because its likely you video card/device and not the monitor may
