Are you running the latest BIOS and graphics drivers version available?
Was there any change on the system configuration? Any program or update installed?
When the black screen error was first noted , during start-up the windows logo will appear and the system remains idle. So i decided to re install the OS once again. Doing so the pc seemed to be ok. Bt when i tried to install the latest driver from the Intel download center , half way during the installation process, the black screen appears and system goes idle.So at present the adapter is Microsoft basic display adapter as i cannot install the intel driver.

Akhilpawathinal, something very important that I would need to share with you is that according to this URL, the DH61WW does not support Windows 8.1 or there are no drivers available. Desktop Boards — Supported Operating Systems
Would you please let me know which is the current BIOS version installed on your board?
I was looking for the latest HD2500 graphics drivers available on the downloadcenter.intel.com, and I found these 2 versions.
Akhilpawathinal, there are 7 newer BIOS versions for this motherboard. The latest one is Version 120
I suggest you to try to install some BIOS versions before installing the latest one. It is important to know that going straight to the latest version shouldn't be a problem, technically speaking. However based on experience, there is always chance.
So, please try to update the BIOS to version 111. Intel® Download Center
I recommend you to check the BIOS Update Release Notes on this URL. You will be able to see the fixes and features included on each version. http://downloadmirror.intel.com/23393/eng/BE_0120_ReleaseNotes.pdf
