Upgrading PC CPU

I want to upgrade the original CPU in my Gateway #450 desktop PC. I've replaced the hard drive and modem several times and I know how to take apart and reassemble a PC. The CPU that's in the PC is still the original one and it's very slow by today's standards. Is there a current one that will fit that model? If so, can I get it from Fixya?

Put in as much RAM as you can afford. I've found that this is the quickest, easiest way to speed up a computer.

    My 450 has two slots, but it had only one stick of 64 MB installed. I found the largest I had in my 'puter shelves and they fit. Now I want to try for 500 MB and see if I can get a DVD drive to work (properly). I've been impressed with this unit being able to take the up-grades I've installed already. Maybe I'm pushing my luck but I'm going to keep doing more until I reach the limits of the mobo or my parts supply.

    For almost any computer, you can go in to advance settings for memory and increase the 'swap file' the space the hard drive uses to send information back and forth to the ram.
    I did this each time I increased the RAM.

I bought a Gateway 450 mini tower, circa 1998 approx.. It had belonged to a local company and it was minimal, 8.4 GB hard drive, 64 RAM, it ran 98 se and I'll admit it ran pretty good.
Being a hobbyist, I just had to find out what she'd do, how far could I push her and still perform.
I replace the Ram with 2 -128 for a total of 256 MB. I put in a 40 GB hard drive and installed XP Pro., expanded the virtual memory a bit.
It was Great.
Then I replaced the telephone NIC card with a DSL NIC card and she goes on-line. Not bad I thought, but it only had a CD-ROM and a Floppy drive. I dug into my parts closet and found an USB card and installed it.
Now, my little 24 year old beauty can receive info four different ways, uses the DSL and is much faster.
Now...after a year or so, I want to keep up grading as much as the mobo will let me get away with.
Does any one know if this two memory slot board will take maybe up to 500 MB or even a full Gig?
I'd love to install a DVD drive that I could play movies on.
This little unit brighten up my day when all these up grade parts worked.
An amazing little machine and if I could, I'd up the processor.
So let's hear it from you hard core hobbyists, please share your knowledge and help me turn this retiree a contender again.

Where the cpu sits on the motherboard there will be 3numbers on the cpu holder which is white and it will tell you what socket it is ie pga370 socket a etc then if you still have the original motherboard manual it will tell you what speed cpu your motherboard will take!

I have a Gateway DX 4850 and would like to upgrade the motherboard. What are my options?

Maybe you are looking for a Gamer PC? However that consists of building or buying a whole new system, because this mother board seems to pretty good. Actually the whole system is fine. It supports and has some of the latest hardware. Besides maybe the i7 CPU, and possibly a better video card, I don't see where an upgrade is warranted.
Here are the specs I found, so if you system differs please state so.

I have a gateway 831gm. it has an Intel (Augsburg) 915G Motherboard and a Pentium 4 630 cpu 800MHz fsb & 2MB L2 cache. i've been looking for a cpu upgrade and saw that the Pentium E5200 Dual Core has...

If both motherboards are LGA775 socket, then the next concern is whether or not the case is capable of having the new motherboard installed into it. Disconnect all power cables to all dv drives or cd drives and hard drives. Disconnect all ribbons from drives to the mother board. If you can get to all of the screws that hold the motherboard into the case, you get away without removing drives. Once you've got the motherboard then you can disconnect the power cable from the motherboard. Remove the memory chips, disconnect the sound cable from the old motherboard. install the memory chips onto the new mobo, Connect the power cable to the new mobo, then install the new mobo into the case. Replace the ribbons from the drives to the mobo, replace the power cables to the drives and reinstall the sound cable to the cd or dv drive. You should be done now.

Its caused by services that update or monitor the drive. Intel motherboards seem to cause HDD to operate with a lot of noise

Central processing unit for Gateway computer

For a couple of hundred dollars you can get a much faster bare-bones desktop or tower and mb cpu combination and move your hardware to it. Upgrading your 450 isn't worth the trouble though jumpers on the board should handle upgrades to maybe 600MHz.
