First of all are you using AGP or Pci video card, or is this intergrated?

Boards beeps 6-4-4 and nothing happens.

The manual is here:

There is detailed troubleshooting information within the document.

6 seems like a Keyboard controller BAT test error.

It sounds though that your motherboard may be defective :( Going to have to get a new one most likely, sorry :(

I have dh55tc, i7 860, 4gb transcend ram, xfx hd 5770, tagan stonerock -u37 600w psu, Its assembled in March 2010 & ran fine for 5 months. One day while watching movie it suddenly froze, i restarted...

3 beeps means that it's a RAM fault. If your memory worked just fine in another pc then it's the fault of the memory controller of the chipset on the motherboard - either the memory slot is loose (move the stick in the slot and try again) or the chipset itself is failing. That can't be fixed, the mobo is dead, replace it.

I am having D101GC motherboard. Suddenly sound card stoped working. I purchased PCI sund card and it was working properly for few months and stoped working. I have formated the system and tried installing...

After installing pci soundcard you really should disable the onboard sound through bios as the PC may just have become confused as to which sound its trying to use. Also in control panel under sound devices make sure your soundcard is listed and the mute box is not checked.

System Fault. No display nor beep sounds.

Here is suggestion: Disconnect the HDDs and other storage devices and then start your machine. If this does not isolate your problem. Try changing the keyboard. Hint: also make sure your motherboard is not touching the metal cabinet anywhere. If so it can cause serious damage to your system.

Intel SE7520BD2 Motherboard or Intel Server problem

Ok, since you first did this with Intel support, then I'm guessing that they also had you first take out the CPU(s) and then reinstall it... Now have you tried testing the RAM in another computer? Last but not least, have you tried switching out the PSU? You could also try to use a POST probe PCI card, to see if you get any indication of an error, or that POST was actually initiated. Usually, you'll at least get a POST beep letting you know what is the problem, but you didn't state that here, so I'm wondering if that is running as well.
