Recently I'm having some strange problems so I decided in place reinstall was the best answer. So I dug my original Windows 7/ultimate disk out of storage and went to reinstall. It won't let me! I get told that I am running a newer version than the about to be reinstalled version of Windows. I have been good about updating Windows through Windows Update. To reinstall process also tells me that two programs are incompatible: C-PCI speaker and advises me to update the driver and MagicISO. When I try to update the driver for the speaker, I get told I am running the newest version. I removed MagicISO. So I am unable to do the in place reinstall.

Any advice?

What problems? Have you tried sfc /scannow from an elevated Command Prompt? –  Karan Oct 17 '12 at 22:03
first thing I tried… It claims that all of my files are okay. The basic problem was that the cursor would entirely freeze up. Even going to the task manager proved useless: get the initial task manager screen but the cursor would not unlock. I can only you reboot. Hence the need to reinstall; or so I thought –  greenber Oct 20 '12 at 15:01

Boot from your Windows 7 DVD, do not use the update/install software that starts when you insert the DVD in windows. In this way, you will proceed with a clean installation of the operating system.

But then I would lose all the work that I had on my C partition! Not what I had in mind! :-) –  greenber Oct 20 '12 at 15:11
no, actually. you can reinstall windows without formatting the partition... and that's the same thing you do inserting the dvd directly from the booted o.s.. However, my advice is copy all your documents and files on another disk/partition and then format the "c:\" partition. It will solve many problems more than an in-place reinstall –  AndreaCi Oct 23 '12 at 6:51

You have most likely updated to Service Pack 1, which when trying to repair install the OS with a standard Windows 7 disk, won't work.

In which case you need a Windows 7 disk with SP1 on it already, which you can download here.

that answer was almost correct: I downloaded Windows 7/ultimate + SP1, cut that onto a DVD and initialized as per directions . It took a zillion years for it to finish (hence my delay in answering) but it finally finished. And it got stuck on a screen welcoming me to Windows as a first-time user. And it wouldn't budge. I tried rebooting safemode and was presented with the same screen. Fortunately before attempting any of this stuff I had made a full backup using Acronis to one of my external USB drives. I was forced to recover the backup, did so and my initial problem has not shown up since! –  greenber Oct 20 '12 at 15:08
Oh right, that's weird, glad you got it sorted though :) –  Bali C Oct 20 '12 at 16:14
