Hi,
I don't think he reached that level yet "webworkings", the guy's problem is obviously way before booting into windows.
Hirak, see if you can access your bios, and see if the RAM,CPU and THE HDD are detected, if you want us to help you better, would you please provide us with your computer model and brand.
Another question for you did the computer dropped? Experienced a liquid drop perhaps? has been connected to a source power for a long time?
