You may need to perform a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 80% battery.

Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).

I tried doing that too but pc companion cant detect a phone when its locked and I dont remember my password 

also that volume press and power button press thing isnt working on my xperia

Run PCC, turn off your phone, follow the steps to repair your phone. Also you could use android device manager.

After connecting my phone to pc it automatically turns on

also PCC wont detect any phone and hence wont repair the phone

Your computer is looking for the drivers, disable any Antivirus and firewalls.

You should try with Android Device Manager
