Finding compatible memory and a new hard drive for an older PC

Dear CNET members,

Happy Friday! Just a friendly reminder to new subscribers to this newsletter: We have an archive of our past Community newsletters, which cover many technical and hot topics. So check it out, because I see a lot of questions e-mailed to me that have been covered before. Also, if you are in dire need of help with technical issues, you can always find help in the CNET forums, where many knowledgeable CNET members and moderators are always willing to give you great advice. So give the forums a try and post your questions there. Now let's get started addressing Dan's questions on finding compatible memory and a new hard drive for an older PC.

Dan, welcome back from your technical hiatus on PC tech. I know exactly how you feel; when you've taken a little break from keeping up with the Joneses it can be quite overwhelming. The good thing though is that the questions you've asked about RAM and hard drives of today versus older PCs haven't really changed that much. And the best part is that you don't have to figure out all this on your own, because your fellow community members are here to get you through it.

In this week's answers, you'll find a great deal of knowledge shared by our members. They have technical definitions for you, recommendations on different approaches in determining what type of RAM your older machine accepts (by using either a diagnostic utility or even Web sites to scan your computer), and when it comes down to upgrading your hard drive, heck, they give you the whole run down. Some members even suggest that it may simply be the time to move on to a newer computer, depending on the cost to upgrade those items. I think once you've read through the answers, you'll be back on track of knowing what's new from the old. In the Q&A section, I've started you all out with a few selected member answers, but please read all the answers. I've learned quite a bit myself, there's a lot of great advice. Good luck Dan! Have an awesome weekend everyone!


Cheers!
- Lee

Last week's question
Finding compatible memory and a new hard drive for an older PC
Question This is a two-part question, but I'd be happy to understand even one of them:

The PC is not brand name. It is running Windows XP, and I plan to add more RAM to it. But I don't know what to buy. How do I figure out which memory will work in a PC (size/speed/max capacity)? I'm guessing some of the RAM available today is not compatible (too fast?) and I don't know what the main board supports. Normally, I'd look at the manual for the mother board specifies is supported, but there isn't one. I don't want to do the trial and error method. Is there a way to find out what memory is supported?

The second questions is about today's hard drives. What hard drives are compatible with anything or are some only supported with the latest and greatest? It used to be there were just SCSI and IDE drives. IDE drives eventually surpassed SCSI drives in terms of speed and became the norm.

All I had to do is look at faster RPMs, faster seek times, and larger capacities and buffers (well, reliability was another). Life for the ignorant was so simple. I've fallen behind the times (even more) and don't know what to look for, especially when I want to upgrade older PCs. I don't know what UDMA and SATA are. Are these connections? Then there is SATA2 or is it SATA II and are these compatible with any "SATA" supporting PCs? Does it work with older PCs that use IDE cables or do some HDs support both while others do not? What is NCQ and is it something I should look for? What else should I look for, as I wonder if these things are worth enough to upgrade the motherboard for too? Thanks!

How do I dual boot my computer to run Windows XP and Vista?
Next week's questionTo begin with, I am not totally literate when it comes to knowing what goes on "inside." I would like to know if it is possible to partition two different operating systems on the same computer. I am using Windows XP, but I would like to try Vista. I have heard good and bad things about it, so I'm reluctant to dispose of XP unless I'm convinced that I really like it. Can you please give me some detailed directions as to how I can accomplish this? Thank you.
