I have an old Dell Latitude c640 that needs some repair work. I am looking for recommendations for local repair shops.<br> <br>The laptop was running just fine with two 512 MB memory sticks. Then it started freezing up after it warmed up. If I only use one memory stick, it works just fine, although a little slow. I ran the Dell memory diagnostic on each stick individually, and both passed. Before I junk it, I thought I would see how much it would cost to fix it. <br>
 <br>Thanks,<br> <br>Mark<br>
