Instructions
1. Remove everything in your computer you can. Find all the cards
installed on the motherboard and pull them out. If you have a video card
please leave it. Then let’s test and see if the computer is powering on
and working. Remove other add-on pieces and peripherals until you have
nothing left but the basics that include the motherboard, memory, CPU,
hard drive and video card. Take out the hard drive and even the video
card if it is on a card. At some point, the motherboard should appear to
work, if not go to the next step.2. Now reseat the video card and hard drive. Take out and reset the CMOS battery is this action does not help. Usually there is a jumper marked on the motherboard that you will have to remove. Take out the CMOS battery after removing the jumper, and then restart the computer and then turn it off and reinstall the battery.
3. Find a good computer and put your CPU in it. If everything else fails, it will come down to either the problem is the CPU or the motherboard. Test your processor in a good computer or try replacing the CPU with a good one.
4. The last step is to replace a motherboard. If you have tried all the steps above, your motherboard is most likely bad and the final test is to replace the motherboard and see if this fixes your problem.
