Perhaps your hard drive has failed or is failing... or a memory module has died. Tell us more about the age of hard drive, general configuration of hardware, OS, etc.

sometime it works fine and then sometime it don't.. could it be a memory failure or power supply?

You didn't answer the query

If it were the Power Supply damage it won't even power up anytime.

It may be your HDD or Memory. For helping you we need that you answer to the question raybay told you.
