You've upgraded it so while Windows 7 should be fine I'd take any BIOS upgrade Dell offers then do the clean install. I'd also follow up the install with drivers for the motherboard from intel.com then the rest of the machine.
I don't think anyone will call it compatible but it looks to be fairly generic.

I ran the Windows 7 Upgrade Advisor and passed with flying colors. However, I went to the Dell website and among the two Dell Dimensions listed that were compatible, the 8400 wasn't listed. I've updated my RAM and my video card and I am in the process of replacing the HDD, which I will install Windows 7 to, and installing a DVD-RW drive. I want to upgrade what I have, rather than buy a new PC.
I am no computer technician by any means, but I am hoping that Dell's website doesn't have the 8400 listed as compatible because of the basic specs of the system. Now that I have upgraded it with RAM and a better video card, I don't see what the problem is.... unless my mother board or something can't handle it.
Any thoughts? I thought I could give it a shot, but I would rather not if it is going to cause major problems. I was going to pick up Windows 7 later today, and it would be great to hear back before then.
Thanks a lot!
