windows 7 installing problems.

Here is the problem:

I had win xp insatlled and i bought win7 cd.I ran setup it was well copied files and when it went to expand files, computer restarted as usually does,but when it restarted,at the win7 logo suddenly the screen becomed black.

I restarted and tryed again but no results, I tryed runing setup in safe mode but the same problem appeared.
I dont know what to do, I tryed to format hard drive with xp cd but when i boot from cd it says "setup is inspecting hardware configuration" and screen becommes black when setup shuld load files.
I appreciate any help here!

I gather you have a computer with no OS installed, neither XP or W7, and that both installers quit or die without telling you anything useful.

The only things I can think of are:

- make sure your install media is OK (checksums, CDs not scratched, etc). Don't use Memorex blank DVDs... Probably not the issue because you have two OSs not installing.

- check your hard-drive and partitions with the bootable-CD version of minitool partition wizard:
"www. partitionwizard. com / free-partition-manager.html" (remove the spaces I inserted to prevent the forum software from chanfing the URL to an advertisement).

Of course you'll need some computer to make the CD...sigh. It's easy to make, tho.
Run the disk-error-check or whatever they call it...

Edit: "I tryed runing setup in safe mode" - you're installing by booting from the CDs aren't you?
Edit: also run a memory/RAM check. IIRC, the W7 install has this.

Try booting the Win7 DVD and not running it from XP. How to Boot your Computer from a Bootable CD or DVD

Test your RAM - Test with Memtest86+ for 5-6 passes, remove all but 2gb RAM to try install.

Then test HD using maker's HD Diagnostic extended CD scan, followed by wiping disk with same CD using Quick Wipe method.
