Windows 7: compatibility check stuck

I have some problems with my windows 7 ultimate so I want to upgrade not format for a clean version. and when the installation gets to the point it checks compatibility it just keeps going and going and doesn't end. I left it for a couple hours and didn't finish so i'm guessing there is a problem.
If there is a way to upgrade without compatibility check it would be great. any other solution will also be great.
Thanks

Disable any running programs such as antiviruses and file scanners before the upgrade

Hello.


You may just need to do it and really start fresh, have a look at this information below and be sure to post back with any further questions you may have and to keep us informed.

After you have copied out or made back-ups of the data you need to save to external media, use Step One of this tutorial at the link below to do a wipe (secure erase) to the entire Hard Disk Drive / Solid State Drive.

• Then if you do not want to create the new Windows 7 "System Reserved" partition use the outline in Step Two #2 to create, format and mark Active a single 100GB partition to do the installation to.
• If you do want to create the "System Reserved" partition use the outline in Step Two #3 to create, format and mark Active the System Reserved partition and then create and format the 100GB partition to do the installation to.

Either way, running the "clean all" then creating and formatting the partition(s) using diskpart will get you the best possible space to do a clean install of Windows 7 to; you can always extend the Windows partition to include the remaining unallocated space on the HDD / SSD or create additional partitions after the installation completes if you choose.
