MATLAB not Opening!!

I am using Windows 7 professional x64.Recently I installed x64 version of MATLAB 7.10.Installation is perfect.It also worked perfectly for about five times.Then later it just flash the opening logo sreen then went off.I checked the task manager for the precess.Matlab is there consumeing almost 50% of CPU.

I tried all methods of disabling visual themes and compatibility modes..

also tried disabling java option with "-jvm" sometime it opens and some times not!!

I am having recent version opf JAVA..

so I decided to swith to 32 bit version as I have perviously used 32bit version of Matlab 2009.

32 bit version of matlab 2010 worked perfectly.but now it is also behaving like the previous 64 bit version!!

I don't know where the problem is there is not any log files regarding this!!

I also mention that I had used 32bit MATLAB 2009 previously it is perfect and also no such problem!!!

is it a problem with MATLAN 2010 or JAVA or Windows7??

please some one help me with this!!
