My Macbook Pro is not booting normally. I tried many options but no success. If I try to recovery mode or try to boot from USB, a blue screen appears. So I can't do fresh install. I checked hardware test, it says ok, I used the disk in target disk mode in my another macbook pro and it runs on there. Only in this machine the problem is occurring.
Youtube Video about the problem: http://youtu.be/mBk-qcvktPs
If you know the solution help me please.

Processor Speed: 2 GHz
Memory: 8GB

From the tests you made we can eliminate a list of potential culprit candidates:
internal disk: use in target mode but you might be tougher on this test: in target disk mode fire
Disk Utility
and perform some (ex.: 4)Verify disk
one after the other.OS: re-install by an Apple service center
Here are the remaining candidates:
Receipe to kill other culprit candidates
If your problem is just due to a graphical chain problem, your system might be correctly booted, but you can't notice it. To check this probability, you will have to set your Mac so as to be able to remotely verify that it is alive or dead.
Connect the bad Mac to a good one with an Ethernet cable,
Boot the culprit Mac, even if it does just show you his blue screen,
Open a
Terminal
on good Mac, and get the broadcasting IP address. The following command will display it:behind the keyword
broadcast
(3rd line). You may also get it at first with a slightly more tricky command:Let's say that it is
broacast_IP
(most probably it will be169.254.255.255
).do a ping broadcast to see how many Mac are alive:
if this command reply you with 2 different IP addresses, then you can conclude that bad Mac is alive and its graphical chain is dead.
On the other hand, if you only get a reply of your good Mac, then bad Mac is really dead, and the last culprit is the good (i.e. motherboard).
