Jeff..first: is your data backed up? Make sure you have all your precious documents, photos, hootchie-kootchie videos, et al safe and sound.
Next: if you think it's a hardware issue, consider a couple of things. You could have a virus messing with your access to memory, so run your virus checker. Also possible is bad memory. It's so cheap, go out and get a set of new & bigger memory chips. I volunteer at a place where we refurb machines for needy folks and ran into an intermittent mem chip set ystdy. Put in a new set and the ailment was cured.
If it's hardware, restoring from an image is a snap. Get an image creation software. Lots of brand name mfr's (such as Nero) make them or you can (at a small risk, not a large risk) download one from the web. An image is just that, a perfect picture of what your drive looks like. Image to an external drive or to a set of DVD's. Many image programs will let you put as much as possible on one DVD, then you put in DVD #2, etc. VERIFY the image to make sure it's kosher (I can explain that when/if we talk). Now, you can safely wipe your drive and then restore the image after booting from the image-making program disk.
You may (and probably should) have a recovery partition on your hard drive already. Is there a D drive marked "recovery?". If so you are really home cheap (but not free). Your computer mfr has instructions somewhere (on the web, probably) on how to install from the recovery drive. It's usually a process of pressing a key combination on bootup. In this situation you would restore, go to the Microsoft Update site and install a ton of updates since your Home Edition was issued (easy to do but it takes little time), reload the programs not part of the Home Edition (you do have them on a CD or floppies or something, don't you?), then copy your backed up data.
Jeff, this is what I went thru at the end of last year after a virus destroyed my ability to boot the computer. Didn't touch the data, just the boot programs. I'm back with everything -- whew. And I image periodically in addition to backing up data. I have more gigabytes of photos and documents than I have hair follicles.
Call me and we can review.
Gooooood luck!
