This problem usually occurs when I am not stressing my system or when my system is idling. I have already changed the thermal paste for my processor (it was over heating before). The problem usually starts with my system freezing then not responding, sometimes my system recovers and sometimes I get BSOD. Though the funny part being my system has never crashed while gaming for long periods (system temp during this is at around 53 to 56 deg celsius). I have observed that the concern occurs more when I am browsing the net. The web browser freezes but I can move my cursor. When I try clicking once of twice to exit the web browser the cursor then freeze it either leads to BSOD and my system crashing or i hear a beep sound and everything is back to normal.

I have reinstalled my operating system I feel the frequency had reduced but the concern is still there. I tried scanning my system with microsoft security essentials for any virus but didn't find any. I feel that the concern started after I changed my graphics card (I had a nvidia gt 9500). Initially the BSOD occurred while gaming the system used to freeze and go into sound loop and I had to restart to get my system working. I then changed the BIOS of my system to resolve the concern while gaming. I have tried stressing my system by playing some of the latest games on high graphics and nothing happened while gaming but the concern is there while idiling my system.

I have attached the details of the BSOD which i have got till now.

bugcheck DRIVER_POWER_STATE_FAILURE
indicates you have a driver that went to sleep but refused to respond when it was told to wake back up.

generally this is a bug in BIOS, the electronics of the device, or the driver for the device.
I can not tell from your info what the device was. Generally, the actual memory .dmp file will have the info if you want to post it on a public cloud server
and give us a pointer.

noramally, you want to update the BIOS and reconfigure the settings, look at the BIOS power management settings and make sure you have a method to wake the machine (keyboard), also make sure the BIOS does not fully turn off your usb hub if you have a USB keyboard (or you can not wake the machine)

after you determine the device that is not waking up, you would update the CPU chipset drivers and the drivers for that device.
if you can not get a driver update, you would go into control panels power management settings and tell windows not to put the device in question to a low link state (sleep). If you can not figure out what device failed to wake up, you would tell windows not to put any devices to sleep. (does not fix the problem, but you won't bugcheck)
 
More tests will help to find the problem, though it could be your power supply not being efficient enough under light loads leading to freezes and such on idle, monitor it's voltages and see if they're within range of their correct values (you can use HWMonitor or AIDA64 for this purpose).

If PSU seems ok test your RAM with memtest86 and then the CPU with Prime95.

Thanks i'll try that but I find that my system freezes when i use my web browser i have to wait for a few seconds i hear a beep and it starts working fine. In a few instanced i found that my mouse froze while gaming (happened in black flag keyboard was working fine). My BIOS has already been updated once and later I have changed the BIOS as it was causing my graphics card to malfunction.
