Monitor keeps going black.

[shadowluva]

Good Morning,

Recently I have been having problems with my monitor. In the midst of using the PC, it will suddenly go black and the indicator light will keep blinking. I highly doubt that it went into sleep mode, as it has been deactivated. Restarting does not rectify it. I will have to switch off the main power switch, disconnect and reconnect all the cables to have it back on (along with PC). Sometimes, there is no display at all when switching on the PC. Only the blinking light.

Would appreciate any help with this. I have a feeling it could be either the VGA or power cable problem.

Thank you

Run memtest. Could be a sign of faulty ram cos I have a similar issue that happen recently.

could be many factors...
as mentioned... faulty RAM..... Power Supply, Overheat.. Graphic Card

When monitor blank... is the PC still running?

Most likely your GPU is overheating. Check the temperature of your GPU.

Download HWinfo and see.

The last time i had such problem, they had to replace my monitor power board.

yep agree with the possible gpu overheating. It happened to my 5770. Same symptoms until i place 2 120mm fans to cool it.
