DELL OptiPlex GX150 Upgrading

I own a DELL GX150 that I got off ebay for $100, Missing only the Hard Drive. I plan on putting a 160GB Hard Drive in it. Right now it has the following: 128MB RAM, 15GB Hard Drive, CD/RW-Drive, Floppy Drive, Intel Pentium III 933MHz, Microsoft Windows XP Home Edition.

I want to upgrade to a Intel Pentium 4, 2.0GHz or better 2.50GHz and atleast 1GB RAM. And I got the new Microsoft Windows 7 I would like to try on it.

Has anyone ever tested upgrading a Pentium III to a 4? and trying a 1GB or higher out of the Max RAM for this, 512MB?

I have the highest Bios version A11 for this.

    I contacted Intel and they told me it is based if my motherboard can run it.

    I own a IBM ThinkPad T20 700MHz and when I turn it on and go under My Computer Properties and says Intel Pentium III 547MHz, 698MHz. I don't know why it keeps changing. Does anyone know why? Its suppose to be 700MHz

    On my DELL OptiPlex GX150 Intel Support says it has a 370 Socket pins, Do they make a Intel Pentium 4 370 Socket?

    And is there a way to get it to read a 1GB of RAM or even 2GB?
    I'm using it for games. aswell as my T20 whenever I travel places.
    I've gotton the new Command & Conquer 3 Tiberium Wars last year at the end of 2008 and still havn't got to play it.

    I just would like to upgrade my GX150 and T20 to a Pentium 4 2.0GHz and 1GB of RAM atleast.

    I'm sure theres ways to get these to work, all the companys told me I could never get Microsoft Windows XP Professional to run on my old 1996 IBM ThinkPad 560 and I got it on there and it Ran fine. Intel Pentium I 120MHz, 72MB RAM.

    I was thinking of buying a new Intel Core 2 Duo DELL Motherboard. Does DELL make motherboards with Intel Core 2 Duo Processors?

    I couldn't find any one ebay. And I would just replace the Pentium III one with it.

    Hi there, I was going to upgrade my DELL OptiPlex GX150's motherboard to a Intel Core 2 Duo. What does the motherboards look like for the kinda newish Core 2 Duo? I don't think the ports need to line up because there is no holes, the Board has the cover attched with the ports on it.

Yes, $100.00 was too much for that system. I saw a refurbished Dell GX270 2.8Ghz 512MB 40GB HD CD/R/RW Windows XP Pro COA w/SP3 and all updated drivers installed for $114.00 + $5.24 shipping (amazon). Also see a Refurbished IBM ThinkCentre A50P(8193A3U) Intel Pentium 4 2.4GHz 512MB DDR 48x CD-ROM 40GB HD for $149.99 + 3 day free shipping (NewEgg). There are a lot of great reasonable sellers on Ebay but it's waters are getting more and more filled with Sharks as well (as well as many other sites, Just used Ebay as an example). I know this info doesn't help much now but hopefully in the future it can. You see a certain price on a system, do a full search on that same system and compare prices and shipping charges on what you find out there.

The fastest processor you can install in a GX150 is a Pentium III 1.13 Ghz processor.

The Socket 370 was a design used only for P3 processors.

Max RAM for that system is 512MB no way to upgrade past that.

If you paid $100 for a GX150, you paid way too much (You can buy a refurbished Dell Dimension C521 for $225 at their refurb site)

You can upgrade the processor to anything as long as the motherboard supports the processor you want. The motherboard also has to support the ram. Tell me what kind of motherboard you have and I can help. You can do this by installing the software cpuZ its a cool little program showing most things about your computer.

    Don't worry its just 2 MHz nothing will differ. And this is how much you have depending on how your system detects it. "I contacted Intel and they told me it is based if my motherboard can run it." Didn't I just say that? As long as the motherboard supports it not detects, it has to be able to support it. If It cannot support it your PC won't turn on. It would be like a human with no brain.

My optiplex gx150 is telling me that the primary hard disk drive 1 is not found what can I do

This message means that the BIOS is unable to find a drive with an Operating System to boot from.

Typically this means that the IDE cable that connects from the motherboard to the Hard Drive is not connected

It may also mean that there is no power cable plugged into the Hard Drive.

Check those first.

Doesn't see hard drive

Try to Go to Disk Management by right clicking My Computer, click Manage.

From the left panel, expand Storage and Click Disk Management.

Do you see your new harddrive from there? If it is a new hard drive, right click and Format it and assign a new drive letter afterwards.

If you need further assistance, just let me know.

Dell OptiPlex GX150 won't do anything.

on the motherboard there is a battery. it looks like a watch battery. there should be a jumper next to it with 3 prongs. move the jumper over to the next prong and start the computer.( it will start but will not come on). turn off the computer and put the jumper back to the first position. start the computer again and the bios will be reset

Dell optiplex gx150 cd drive won't boot

Hmmm--when you went into the BIOS setup, your first boot device should be CD. The next your hard drive. The other boot devices should be set to disabled. Now if you have a third boot device as a network device, then your computer is not seeing the CD or the Hard drive--you have a problem. If all the drives are hooked up properly (sounds like you have that covered) then your motherboard is probably the problem.
I would try to disconnect all your stuff except the CD. Try it on the first IDE channel (set it either as cable select or master). If that fails, try it on the other channel. Do you have a second CD to swap out?
Still no boot? Bad motherboard.

Motherboard upgrade for Dell GX150

If the motherboard you have installed accepts a socket 370 processor and you replaced the board, it would also have to be a socket 370 unless you were planning on upgrading the processor also. If you wanted to keep your existing computer case and other hardware, you might want to look for an inexpensive pentium 4 motherbard and processor to replace it instead of the pentium 3 you now have. If you get a new board that uses the same memory that you now have installed it would be a relatively inexpensive upgrade.

Dell system restore

Depending on the operating system, most of the time it is located in the start menu, programs, accessories, then system tools. Restore is a process that takes the computer back to a specific date and time called a checkpoint. Reformat is a process by erasing the entire hard drive and re installing the version of windows you are running.
