hello, linkmaster!
thanks a whole bunch for all your help!!!!
i think my computer is back to normal now(all thanks to your help!

)
i really appreciate it.
but i have to ask you something about my START menu.
when i open my start menu, it doesnot allow me to use the right-click (using mouse), and i can't move the list of programs like i normally able to... this have been going on for a while now. do you have any idea why that is happening to my Start menu? ( i think this is a little out of topic but... i dunno who to ask... i dunno anyone who really know a lot about computer like you guys in this forum...

... hope someone can help

)
