The monitor not displaying anything. I don't hear the POST signal as well. ( the beep while booting )

Things that I have tried.

  • Connected MONITOR to laptop ( which I am using currently ), displaying properly working fine. So, it is not the Monitor's fault.
  • Connected keyboard USB to desktop while booting ( it is detecting keyboard, I can switch numlock off/on )
  • Cleared CMOS by touching two pins ( reading the motherboard manual Gigabyte that I got from shipment )
  • Switched RAM's, placing them in different slots and placing only one RAM instead of both. Purchased another ( better RAM ) Kingston DDR3 ( saw the mobo manual and checked if it supports ).
  • Removed the RADEON HD 6870 Graphics card from its slot and put it back again to make sure it fit perfectly.
  • Also, removed DVD drive, because I don't need it now.
  • Also, removed all the USB drives ( no keyboard, no mouse ).
  • I have also tried removing all the RAM(s), and booted the system. It is turned on for some time ( around 6 seconds ) and turn off automatically, and then turn on again. It happened 3 times, So, I turned it off. I made sure, the speakers are on all the time, no beep/weird noise heard. ( Recommendation attempt from Luke )
  • replaced PSU with the one that I borrowed from my friend, it still doesn't give any beeps while booting. monitor still not displaying anything. Now, I am guessing the motherboard/processor is at fault.

Nothing helped.

I see that the fan-supply that is connected to the processor is spinning and the fan on the RADEON is also spinning.

I don't hear any weird beeps/noises while booting.

What do you guys think?

I agree, the power supply is next. If you don't have another one, and you're sure the speaker is connected (for the POST beeps), remove all the RAM and see if 3 beeps are sounded.

Just out of curiosity, is this a new build or a computer that suddenly stopped working?

I got this computer from a company( ibuypower ) today. I thought of building it myself, but got lazy and didn't do it. got served I think. PSU is from some company I have never heard of, so I want to replace it with a new one ( good company ) hopefully, it will fix it. I don't want to send it back ( shipping costs me extra ) –  user122530 May 12 '12 at 2:26
    
Never heard of that company... Hopefully it does get fixed with a new PSU, but I would also then send them the bill for fixing it –  Canadian Luke May 12 '12 at 2:35

I hope I can get a complete refund on this junk. –  user122530 May 12 '12 at 17:05
