Ok so im trying to fix a friends computer. it will simply not start up.
when i flip the power switch the fans move for a second, then turn off. the power on the mother bored still shows it is on. and the fans wont spin again until i restart the power supply.

I have unplugged everything and put then back in, includeing the cpu. and the battery. i have reset the bio from the 1-2 pin to 2-3 pin and back. and removed the battery, i did everything in this video

i have tried switching the voltage on the power supply. still no avail.

i have tried unplugging the 4pin connector and still no avail.

he has 2 ram sticks in. and i have checked the cpu to see if anythings bent, and its not.

here is a video of what it is doing exactly

Here are some ideas from a Tom's guide:
1. Make sure that the CPU is supported by the motherboard, check the CPU Support list on the manufacturer website.

2. Check for visible bent or broken pin(s) in the CPU itself.

3. Check memory requirement and memory installation, make sure the RAM stick(s) are seated properly.

4. It is always good to test the board with a single stick to rule out a single bad stick of memory.

5. Make sure that the ATX 24-Pin and ATX 12V 4 or 8-Pin are plugged in firmly into their sockets on the motherboard.

6. In case you have installed an graphics card on PCI slot, please check if the card requires additional powers 4, 6, or 8 Pin PCIe power.

7. Test the motherboard on a non-conductive surface or test...

6. In case you have installed an graphics card on PCI slot, please check if the card requires additional powers 4, 6, or 8 Pin PCIe power.

7. Test the motherboard on a non-conductive surface or test bench to rule out the grounding possibility. It is a good practice if motherboard and other components are tested on test bench before putting in the Chassis or computer case.

8. Check monitor for video input selection, VGA, DVI, or HDMI.

9. Check the VGA/DVI/HDMI cable and ensure that cables are not malfunctioning. Test with other video cable.

10. Avoid using any video adapter or KVM switch.

11. Clear the CMOS by taking out the CMOS battery from the battery socket on the motherboard, leave it out for 5 minutes and place it back. Make sure that positive side of the battery faces up.

12. Some motherboards like Asus Maximus series boards have dedicated clear CMOS button which comes in handy for the step 11. Not all motherboards provide this support.

13. Ensure that power supply is not malfunctioning. For this purpose test the power supply by using either of the methods described below:

Test Clip: Watch the video on how to use paper clip for testing:
Test Clip Vid

Voltmeter: Use a voltmeter, if available, to test the power supply. Watch the video:
Voltmeter Test Vid

14. Ensure that your power supply has sufficient juice to supply the power to your system. Check this video on determining how many Watts does your system need:
Wattage Requirement

With these steps, it is most likely that you will solve the issue.

Good Luck,
