Windows 7 - Computer won't start after a successful restart

First of all, this is my first post in the forums and sorry for taking this advantage to ask a question immediately.

I'm desperate and so confused about my problem. I experienced this problem since I tried to consult my constant BSOD problem in my computer to a 'computer technician', resulting couple of problems, HDD failure and she made a so-called 'tweak' on my BIOS, to make the long story short, she didn't solved my BSOD problem. Ended up buying a new hard disk.

I bought a new hard disk and a legit computer technician installed it. No BSOD or anything, my computer runs smoothly and runs like a brand new one, but the problem is my computer won't start after a successful restart. Monitor's light is blinking and the CPU's fan is still running as well as the CPU power button.

Can someone please do help me? Please do explain the instruction in a much easier way, since I don't have enough knowledge in computer terms. It will be highly appreciated if someone will do.

Advance 'thank you'.
