well if the hard drive was the problem, which i dont think it is, you should still be able to see the bios screen. it sounds more like a motherboard issue to me. asus are good mobo so it sounds like you were unlucky and got a dud

It is not the BIOS.

A BIOS issue is one of the most RARE problems you can have with a computer, and the symptoms you describe are more indicative of a hardware failure.

I would try one RAM stick at a time, to see if one of them are bad. From there, remove any unnecessary components from the system. All you should have connected is the CPU, Motherboard, PSU, RAM and Video card.

Now, if that solves the issue, then add parts one at a time testing each time to find the offending component.

If it doesn't, then you have isolated the issue to those 5 components.

If this is a new build, it is common to have a short when you have issues like this. So you should remove the motheboard form the case, and make sure there are no stand-offs contacting the board where there is no screwhole and be sure there are no loose screws.

Since you have the board out of the case, you should set it on a piece of cardboard and test the setup OUTSIDE the case to eliminate the possibility of a short causing the problem.

If it still does not work outside the case, then it is simply a process of elimination to determine which component has failed.

But my money is on a short considering there are no beep codes.

Have your tried booting to safe mode and adjusting the screen resolution?
