When I turn my computer on, only the monitor turns on

By khalid3ahmed ·
My desktop computer is shutting down without warning me and when I try to turn it on only the monitor lights up, the computer doesn't working.
I sure that the power cable to my PC is firmly pressed into the powersupply terminal in the back and I checked inside the PC and I see that the main power connector is firmly attached to the mainboard.
pls help me, thanks in advanced...

Does the motherboard LED light up ? ...

When you checked inside the PC case, did you notice if the LED was lit, or blinking or what?

Can you tell us the make and model of your computer?

My rough guess

by Dumphrey In reply to Does the motherboard LED ...

would be a bad video card/driver since the monitor is "lighting" up but not showing the not connected image (or it was not mentioned)when they turn on the computer... Another possibility is the computer is over heating.
But more detail of the problem is needed as OM suggested.
Can you boot the computer into safe mode? Can you find any link to the computer crashing? High cpu load? Video game running? Any error reported in event viewer after the crash?

Are you running the wrong voltage...240 volts. It should be 120 volts (in USA). Your power supply may be bad or (during a move of the CPU) might have a bad connection with the motherboard. And like it was said do you have lights. Some computers have "ABCD" lights located on the outside of the case near the audio/mouse/USB ports (on back of Desktop). (Depending on your computer) All the lights should be lit up. We need more information to give you troubleshooting.

Have you updated your bios?. Update here.

http://driver.wareseeker.com/Bios/msi-ms-6540-bios-3.4.zip/335773

You might need to use another computer to download this onto a floppy disk. When you have copied this to a floppy place this into the computer in question and go into the bios (press either F2 or Delete buttons on your keyboard, or what key/button that is related to your bios) and go to the bios section that does the update and follow the on screen instructions.

Please post back if you have any more problems or questions.
