I recently built an Antec 900-2 desktop, and for a few days it was working perfectly fine with no problems whatsoever. However, last night I left it on to download something and when I turned it off to let it cool, I turned it back on and I encountered this problem:

It would go through protocol with no hindrance and problems, but once I pass the login screen, it goes to my desktop and it makes the trademark "Windows login" sound halfway, and then shuts off... but not completely. On my monitor, the screen turns black and says "No Input Detected", while the PC is still on and running... but in a half-conscious state. Like, I can't press any of the buttons on it, including reset, power, etc. Even if I hold the power button for 5 seconds, there is no response.

I initially thought of this as a power issue so I moved my desktop to a place which receives more power than my room, but that was to no avail. I then thought it was a monitor issue, but it can't be the case because the monitor tells me there's no input detected despite all the wires being plugged in. Then I tried running it in Safe Mode - same thing happened. I tried running it Normally with Command Prompt, and it still "shut down".

My friends and I concluded that it was definitely a PC problem- likely in the motherboard. The desktop still "runs", it just doesn't respond. The monitor's input shuts off, but power still flows there too. Perhaps I built it wrong, but even if I built the PC incorrectly, ideally it should have malfunctioned right from the start, instead of being functional for a week.

So now I'm lost and typing this question with a boiling sensation which feels quite close to impatience, bewilderment, and confusion. Can anyone help me at all? By diagnosing what the problem IS, what I can do to rectify it, and what steps I should take to prevent this from happening again.

Thanks... I truly do appreciate it!!!

What are the exact specs? Are you using integrated video or dedicated? if its dedicated, and you have a integrated card, try to remove the dedicated card and boot up off the integrated and see what happens.
