Windows 7: What would cause RAM to be unusable?

It can be that simple. Ram being jarred in transport.
I just helped another member with ram problems. In post #5 I recommend removing and installing ram again and in post # 14 he/she tried my recommendation and it worked. It's not always that easy but who know you might get lucky.
Good luck and keep us informed.

Now I feel really stupid. I always look for the hardest fix first. I'm the kind of guy that, when I flip a light switch and am surprised to find a dark room, I go grab my meter and start checking the wiring, never thinking to check the light bulb! Maybe it comes from 22 years as a maintenance guy.

Once I got home from closing on our new house, the first thing I did was open my computer and check out the DIMMs. Nothing looked amiss. The DIMMs seemed to be seated perfectly. Still, I went ahead and unlatched them, pulled them out and gave them a quick look, then reinstalled them, making certain they were seated and latched really well. I knew after checking in BIOS and seeing 4088 MB that everything was good. Once getting into Windows, System shows 4 GB install and makes no mention of only a portion being usable. Resource Monitor only shows 9 MB as hardware reserved.

Thanks for all of the advice, especially the advice to look at the simple things first. Reputation boosts all around.

Well now that is the way memory should look.
Glad things are working now.

Happy computing.
