SOURCE: Asus mobo flashes on startup, no video
You should unplug the power cord from the power supply, pop out the cmos battery, switch the bios reset jumper to the 2 and 3 pins, wait about a minute, put the jumper back to 1 and 2 pins, put cmos battery back in, plug in power cord to psu and turn on pc. If you have any issues with this process please refer to your owner manual for the motherboard or look one up on their website. Please let me know if this fixes your issue.

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive Test all leads that attach to your hard drive including electrical extensions,IDE,SATA the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error hope this helps
