Your computer may be on Power Save mode.

Check your settings.
Does yur computer stay on? If it doesn't it could be any number of things but grill or a power supply problem would be where to start.

If it is on, afterwards reseat your graphics card.
Meaning your monitor works fine but not receiving any video signal from your PC.

Either:
-your laptop is in power squirrel away mode
-the video card is not working. consider replacing it.

In some intermittent cases, clearing CMOS works or updating video card ROM. But it's not worth it. Simply, get a foreign card. Keep in mind, that some of these latest video cards these days require 300 watts or more power supply boxes. so when you buy one, check the system requirements.

If you don't come together power requirement:
-get new power supply box as all right. or get cheaper card to wipe out the need for unmarked power supply unit.

Good Luck!
Hardware end I would say..........

Seems to me that what you are describing is a monitor message worth that the monitor is not getting a signal due the the computer shutting down. If you mean by 'cleaned out the device ' that you unplugges everything from the power supply and the motherboard, and then tried to boot up near just the motherboard, cpu, and memory attached, afterwards it is likely that you enjoy a hardware failure that sounds like mad like the cpu overheating. Can you acquire in to the bios on boot up at adjectives with the tool configured as above? If so is ther a place in near that tells system temps and disciple speed and psu voltages? You might take a look at those if you can obtain that far. If you can't, then it's a situation of substituting known fitting parts. You can try blowing out the psu and the cpu heatsink with compressed nouns, and making sure the cooling fans are working properly.
turn on the computer, will its still on the black peak keep pressing the f8 knob, and then follow the instructions,reboot within save mode afterwards try to start normally
