The process I've done now has been performed on safe mode since performing any action is taking too long on normal mode . Now after all these steps have been taken, the lag has reduced but still experiencing those in normal mode . If I play a movie or any video clip the audio is like in slow motion and all breaking up and gets stuck. If I connect LAN wire , this lag increases even more .

Are you saying there is no problem in Safe Mode ?
You only have the problem in Normal Mode ?

If that's true, do a clean startup to try and find what program(s) are causing the issue.

Troubleshoot Application Conflicts by Performing a Clean Startup

I have uninstalled vaio smart network as you asked Mr Gator and also I have reinstalled my LAN driver, the lag spikes have reduced but they still exist . Opening my computer or partition disks or any folders takes long time . I have a system image I had created after clean install before , maybe I should restore my system image, I need help with that too if it's the only way to get rid of this problem .

If that's true, do a clean startup to try and find what program(s) are causing the issue.

I have try all the steps listed in the link you've posted . I find an unknown program on my startup list named as convert ad.exe. And when I follow the path to its location I don't find any file with such name, tried even viewing hidden files . Must this be the problem ? How do I remove it.

Yes Mr Bear. I have performed malware bytes , super anti spyware and adw scans and have cleaned all that's been found as a threat with these respective programs. But I still experience these lag spikes . This does not occur in safe mode(rarely actually,) .
And I have even performed a clean start up as Mr David suggested . And that how I've seen this unknown program convert ad.exe .

Also, did you ever run an SFC Scan? May or may not do anything at all, but it never hurts in situations like this.

SFC /SCANNOW Command - System File Checker

As there were couple or more methods in the link. I chose method 1 as it was easy . And I have run the sfc scan using command prompt, and it resulted in no errors .

But, the original code in the link was:X:\windows/system32>sfc /scannow /offbootdir=F:\ /offwindir=F:\windows.
whereas, I have it as X:Sources> . Is it okay with this? or do I have to change that and perform this scan again, if so tell me how that directory could be changed .
