Where did you get Win7? If you burned the DVD yourself, try burning another using ImgBurn at 4x speed.

WHile you still have XP, make sure you have latest BIOS version update. If so, reset your CMOS: http://pcsupport.about.com/od/fixthe.../clearcmos.htm


Try wiping the HD before install: SSD / HDD : Optimize for Windows Reinstallation

Boot the Win7 DVD to Custom install, use Drive Options to partition and format before install. Clean Install with a Upgrade Windows 7 Version

If problems persist, test your HD using maker's diag/repair full CD scan: Hard Drive Diagnostics Tools and Utilities (Storage) - TACKtech Corp.

Then boot the DVD, press Shift + F10 to open a Command Line and run Disk Check

Test your RAM using memtest86 for 5-6 passes. Swap RAM sticks, remove all but 2gb to try install.

Here are also some tips on getting a perfect install, based on hundreds done here: https://www.sevenforums.com/installation-setup/125874-re-install-windows-7-a.html#post1086729

Thanks for the info.
I solved the problem. It's nothing wrong with my hardisk. Wn7 could not somehow detect or trying to install the driver automatically causing black screen.I used old 256mb VGA card to install and change to current one later.
Hope this could be a help for others
Cheers
