Actually I have two questions.

I have an HP xw8200 Workstation with dual Xeon 3200DP 3.2 GHz. 8 gb of memory. It was suppose to have XP professional?? Not sure, when I turn on the computer it just says windows XP, no home edition or professional.

(1). When I check the properties in "my computer" it appears to only recognize 3 gb of ram. What do I need to do to get the full 8 gb working? I don't know what is installed, a 32 bit or 64 bit? (How do I find that out?) Do I have to completely upgrade to a 64 bit or can I just D/L 64 bit drivers or something, if that's even possible?

(2). When I shut my computer down (correctly), sometimes, and only sometimes it will beep and flash a red LED and won't start up. I can get it started if I pull the power plug from the rear of the computer completely out and wait about 10-15 seconds, replug, and then it turns on. Whats the problem and how can I avoid this situation?

Thanks for any help.

Windows XP is limited to 4gb of RAM. You won't get more than that, if that (sometimes limited to 3.x depending on devices), to recognize. You would have to be running a 64 bit system to get more.

Any 32 bit operating system is limited to 4GB max. Less than that actually because of hardware like the video card that needs address space. 32 bit versions of Widows XP, Windows Vista, or Windows server all have the same limitations. 64 bit versions of Windows XP, Windows Vista, or Windows Server will all be able to handle much more than 4GB.

When you right click on My Computer and get properties, it tells you which version of XP you have (home, pro, media center). XP64 will tell you its 64 bit. Otherwise, its 32 bit.

There's no upgrade from 32 bit to 64 bit. You'll have to purchase the 64 bit version of either Windows XP or Windows Vista, reformat, and install it. You'll then get access to all of your RAM.

Nope, unfortunately you can't upgrade from 32 bit Windows to a 64 bit system either. If you are running Windows XP 32 bit, you would have to install Vista 64 bit on a freshly formatted hard drive. Now, before you go doing that, make sure all the components are 64 bit ready. One device driver not up to date can really make a mess of things. That must be emphasized a few times.

Just out of curiosity, why the need for so much RAM?

I do a lot of music editing and graphics. I have to have many windows open at a time.

Ahh, cool. Can never have enough RAM when doing multimedia. I have one of the 24 inch iMacs at work and I'll tell you it's insane how many windows I can open up on multiple desktops. It's a multitasking monster. Ever considered going that route?

I hear MACS are great and not hard to operate. I'm really use to windows but I love learning new things so yeah, I think at some point I may crossover.

Thanks again for your advise.

Just for kicks, I once had over 100 windows open. They were static, though, not playing music or anything. I have 2 gigs of RAM.

Not 'quite' true - Physical Address Extension (PAE) will allow you to utilize more than that barrier. Although I don't think XP will. But the Enterprise editions of Windows server (and up) and various *NIX systems support that. THus allow those 32-bit systems to utilize up to 64GB of memory.

HOWEVER, that just allows you to load more apps... but most apps written for 32-bit systems won't see past the 4GB total barrier. Meaning that if even if you have an OS that can use PAE, the applications on it most likely wont' see more than 2GB (as its assuming the other 2GB is used by the Kernel).
