Hi,

I just built my first PC. (Well, still in the process of) And I have everything plugged in and together minus the OS.

When I power on the computer, it turns on for a split second. Stops. Then turns on again and runs fine. All the fans are spinning after that, as well as the standard "You have nothing on here" screen.

Is this normal?

Thank you!

Now this depends on what exactly is happening. The system to power on then off then on again is not normal. Have you entered the Bios and made sure your settings are correct. A bad setting can make some systems boot in factory settings, causing the system to try to post, realize there is an issue reset and reboot with factory defaults.

first thing to look at is the Bios set correctly.

New Update: That problem stopped. I installed Windows and shut the computer off. Now it will not even attempt to power on! Help!

Light on the motherboard is green, so I am assuming it may be the PSU?

There is no bumping allowed on these forums. Have you double checked to make sure everything is plugged in all the way? This consists of PSU cables (24 pin main and 4 pin or 8 pin CPU supplemental power connectors - 6 and or 8 pin GPU power and add on component Sata/Molex connectors), Ram modules, GPU and or add in cards, Sata cables, USB and front panel connectors.

What are your system specs? Are there any post beeps? many motherboards need a case speaker to be attached to hear them. this little speaker comes with the case and will give a set of beeps that changes due to what trouble it is getting during the post operation. POST= Power On Self Test.

After making sure all are connected correctly and still you still have a no boot situation, try to boot with just one ram stick in and then the other. If this still fails to boot remove all components from the case and rebuild it on a table or bench (AKA bench building) this eliminates the case.
