Windows 7 Problems????????

Few day ago i was using windows 7 fine and then it started doing some stupid things like when i login, i can't click anywhere. I have to Press CTRL+ALT+Delete then i can click sometime without click, when i hover over icon in super it just open when i put arrow over it. so i decided to install Fresh windows 7 in another partition. After i installed it i don't see my old windows 7 in boot menu and i tried to use Easy BCD but it didn't work. New fresh windows 7 have same problem whenever i login i can't click on superbar.
my Question is that what could be the problem for superbar to freeze.(i also scanned found no virus). Another Question is that how can i bring my old windows 7 to boot menu so i can login on that again.(i didn't delete my old windows 7 partition)

thank you

Hi, if you got the Windows 7 cd, insert it and reboot your computer.
Let the disc run untill you can choose if you wanna reinstall win7 or repair. So just repair it, and all your files wont be deleted and you will get an working win7.

P.s. activate windows updater, and update everything, and fix all drivers.

i tried but didn't work and now it freeze when i am watching video or something and i have to to ctrl alt delete so i can click anywhere again.

humm strange, well can you reply with your computer info?
And what browser do you use.
What internet do you have.
What gfx card
and all that.

i repaired windows 7 and it is working for right now but sometime when i am watching video or something it freezes but it doesn't happen often after repair. so thx

Update your video card driver. Or if necessary, physically remove and then reinstall your video card.
