computer starts but no display

by spirit2121 / September 6, 2011 4:41 AM PDT

When I start my computer it doesn't display anything. The monitor is blank. Then I turn off my computer by pressing the on/off button on CPU, after it is off, I turn my computer back on. This time the computer is showing display.
I can't figure it out why it doesn't display at 1st time? Had check anything wrong with graphic card, memory cards, processor, processor coller, all the fans and motherboard, but cant find what is wrong. Any help??

That is one of the symptoms of BAD CAPS.

Google BAD CAPS and read about how to visually inspect and identify these parts.

PS. Too bad the make and model was not revealed. Might be one of millions that died.

Next is the age of the machine.

As these electrolytics age (just a few years) you will encounter machines that won't start cold. The test is easy. Turn it on and give it a few minutes. Turn it off and back on and it usually starts. Your best bet is the motherboard but change the PSU first and add 100 Watts to the capacity.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
