Question about PC Desktops
When you say you hear the computer working and working do you mean that the fans are going and the lights are on?
i ask this because the fans and power lights can come on just from the power supply coming on when you push power but that doesn’t necessarily mean the cpu is functioning.
Do you hear a post system beep and the hard drive reading files also?
Or does it just sound like only the fans cam on ?
If you think that possibly only the fans are working then try this
Shut down the computer and unplug the power cable.
Check to make sure monitor cable is connected all the way
Open the case and check to see that the video card is inserted all the way into the board properly
Remove the memory (RAM) and then put it back in to make sure it is properly seated in the slots
Plug in computer and try it again and if it still does not work then try clearing CMOS
on some systems you can clear the CMOS very easily by just holding down the insert key on your keyboard while pressing power button and continue to hold it down when releasing power button until you see something on the screen but since this does not work on all computers you might have to do it manually by moving the CMOS jumper on the board
(the CMOS jumper on the motherboard is usually the one closest to the little battery that you see on the board. with the computer off move the jumper over one notch to the other pin for a second and then put it back where it was (there are usually only three pins so this is easy step)
You should now be able to boot but you will need to go into the CMOS setup and set the clock again and other settings
If you still have a blank screen then let me know and i will take you to the next diagnostic step...
Hope this info helps
