Windows 7: 64 bit Install Issue

Hi guys!

For weeks I've tried the 32bit version of Windows 7, and like any normal geek, I wanted to try the 64bit version, my cpu supports 64bit OS's, and I even downloaded the 64bit version from msdn back in december, but I haven't been able to install it... no matter what I try I can't get pass the Starting Widows first screen, I mean, it boots from the dvd, then it copy the install files and then it says Starting windows... but it just locks up.... freezed!.... Maybe the 5 HDD have something to do with it? maybe some BIOS config? I have the 7000 build, 1,5GB RAM; a 2,8Ghz Pentium D and a GFX5550 256Ram video card in Dual view... Disks are not RAID and I have only a dualboot 32bit XP and 7.

What should I try?

Any words on this? I'd love to get some help...

Thanks in advance!

By the way... I burned the image using a Nero Suite (8 I beleive)... ans the dvd was burned at 4X...

Thanks again!

Problem solved!... I installed on a fresh and brand new hard drive and it worked just fine! You can close this post now... Thanks!
