Newly built computer, Bios freezes after few seconds of entering

I would start checking electrical connections and make sure all are connected, fully seated and none, such as the front panel connections have the polarity reversed. Disconnect everything that is not required for the computer to post. On first post, you should be required to enter bios. No hard drive is necessary, disconnect both connections to it and try with 1 stick of ram, remove the Graphics card if you have on board graphics and use on board graphics. Remove everything that is not required for the computer to POST and get into BIOS. If you can do that, it will tell you a lot of things.

Try with a different mouse and keyboard if you have or can borrow one. As basic ones as possible, some boards have issues with gaming keyboards and gaming mouse. As soon as you enter bios load optimized defaults (typically F5 on Asus boards) as soon as possible. Once you do that, if you can navigate check your Hardware monitor for PSU values for the +12V, +3.3V and +5V. Also check the CPU temp and motherboard temp. You might also check the CPU cooler installation before you try. Make sure it is secure.

If all of that fails. Remove all of the ram and try to boot with no ram installed. It won't boot. You should hear a long serise of beeps. If you do, that is good. It means the motherboard is doing what it is supposed to do.

Try those things and let us know what happens

Javx123, also if you don't mind. Please fill out your system specs as completely as possible in the UserCP. That will put them in the bottom of every post. It will save us from having to go to post #1 each time we want to see something. You can click at the bottom left corner of this post to see mine to give you an idea of what we want. This will help you if you need it. System Info - See Your System Specs

Something caught my attention. Drivers can't be installed unless the OS is up and running.

Yeah I saw that, I figured that is was a mistake and that the OP is attempting to install the OS
from a USB thumbdrive.

That was my impression also.

Wow. My impression was kittywoppered; sorry.

Do you have a case speaker connected to the front panel connections? I would try all the suggestions given. If none of them make your computer post, I would RMA it. Does your board have a digital Q code on it that gives error codes? Do you have error leds that show what has failed. Most of the newer Asus boards have one of them or both. If you knew what was causing it not to post, you may be able to fix it. I would try all the suggestions first though. Also, if you can return the board to the retailer for an exchange rather that going through Asus, you will have a much easier and quicker time of replacing it. Take that as the voice of experience. Most retailers allow you to return a defective board within 30 days of purchase.

EDIT: I just re read your post #1. The board is posting, just freezing in bios. Do you know what version of bios is on the board? The freezing once in bios could be most anything causing it, including a corrupted bios. If you have a dual bios, switch to the other chip. How much experience with computers does your friend have?

My personal opinion, it could be a bad CPU, but if it is, that is an extremely unlikely problem. It is quite rare that you get a bad CPU. A bad PSU, Motherboard or ram, yes, it happens quite frequently, but a bad CPU is extremely rare. Start up is an extremely stressful time for a computer. Remember, you are going from off, a complete stop, to full power on every component. That puts stress on every component and a bad or even weak component is going to show up and not work correctly. See if you or your friend can use a multi meter and keep tabs on the PSU, especiallt when under strain. See the values and how much fluctuation there is in it. Swap Graphics cards with your friend and see how his computer does with yours and how your computer does with his. Try a different hard drive, Disconnect all drives except for the new one. See whay happens. I rebuilt my whole computer once because I couldn't get it to post. All the time, it was a bad hard drive that wouldn't allow the computer to start. Try borrowing if possible all components of the computer and testing them one at a time until you find the one causing the problem. If you go through that and still have no resolution, your problem is the motherboard or, as your friend said, the CPU as that's all that's left.
