New processor needed

Only if your motherboard supports this CPU, you need to find that out on the MB manufacturer's site.

The motherboard for the dc7600 has an Intel LGA775 processor socket. However, not all LGA775 processors are compatible with the motherboard. For the small form factor, the following CPUs are supported: Intel Celeron D Processors:
Intel Celeron D 331 Processor (2.66-GHz, 256K L2 cache, 533-MHz FSB) , Intel Celeron D 336 Processor (2.80-GHz, 256K L2 cache, 533-MHz FSB) , Intel Celeron D 346 Processor (3.06-GHz, 256K L2 cache, 533-MHz FSB)
Intel Pentium 4 Processors with HT Technology:
Intel Pentium 4 521 Processor (2.8-GHz, 1-MB L2 cache, 800-MHz FSB) , Intel Pentium 4 524 Processor (3.06-GHz, 1-MB L2 cache, 533-MHz FSB) , Intel Pentium 4 541 Processor (3.2-GHz, 1-MB L2 cache, 800-MHz FSB), Intel Pentium 4 620 Processor (2.8-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 630 Processor (3.0-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 631 Processor (3.0-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 640 Processor (3.2-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 641 Processor (3.2-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 650 Processor (3.4-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 651 Processor (3.4-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 661 Processor (3.6-GHz, 2-MB L2 cache, 800-MHz FSB) or
Intel Pentium D Dual Core Processors:
Intel Pentium D 805 Dual Core Processor (2.66-GHz, 2x1MB L2 cache, 533-MHz FSB), Intel Pentium D 820 Dual Core Processor (2.8-GHz, 2x1MB L2 cache, 800-MHz FSB), Intel Pentium D 915 Dual Core Processor (2.8-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 925 Dual Core Processor (3.0-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 930 Dual Core Processor (3.0-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 940 Dual Core Processor (3.2-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 945 Dual Core Processor (3.4-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 950 Dual Core Processor (3.4-GHz, 2x2MB L2 cache, 800 MHz FSB)

Unfortunately, these are old processors and I don't see any available new. Newegg.com lists a couple available as refurbished. You may be better off getting a new computer with either a Intel I3 or current AMD processor.

I wish that I had better news for you.

Please Vote if you mind and thanks for using fixya!

Flash is software that you put on your computer and a celeron processor running @ 1.6ghz is a CPU hardware, flash should be able to run on any cpu. My netbook has a celeron processor running at 1.7Ghz and it runs flash just fine, try downloading it from adobes website.

Well, unplugging something (I'm not quite clear on what you unplugged), especially if it supplies power to the processor usually doesn't fix things. If you mean the plug that looks like http://www.pcguide.com/byop/diagrams/figure9.jpg then it helps supply power to the motherboard, and I'm not sure what unplugging it would fix but it is more likely a motherboard issue than a processor issue if unplugging it fixed the problem. Regardless because this is an older and off the shelf computer upgrading it will be difficult due to the fact that celeron's don't have the same socket type as newer processors. If it is a motherboard issue then you will need a new motherboard and a new processor for that motherboard. Essentially the easiest and most cost effective thing would be to get a new computer.

tech-gu818,

When looking to see what processors a computer will support, try to find out what motherboard chipset is on the motherboard, and the processor socket.

The motherboard chipset is the;
1) Northbridge chip
2) Southbridge chip

[Chip and Chipset are slang terms for Integrated Circuit, or IC.
A Processor is one type of Integrated Circuit]

The Northbridge chip is responsible for handling the Processor, Ram Memory, and high-speed graphics, such as AGP, or PCI-Express.

Integrated graphics, or a graphics card installed in a PCI slot, is handled by the Southbridge chip. The slower capabilities of a computer are handled by the Southbridge chip.

This motherboard diagram may help further illustrate the above statements,

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

(You can also type,
1) Northbridge (computing)
2) Southbridge (computing)
in Wikipedia's search box to obtain more info )

How to find out what motherboard chipset the eMachines W3502 uses?
Three ways:

1) Go to the computer manufacturer's support website, and look under Specifications.
2) Download the free, tiny, program CPU-Z from CPUID.com
3) Download the free, tiny, program Belarc Advisor

Fortunately eMachines Support lists what the W3502 motherboard chipset is,

http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=W%20Series&model=W3502

Chipset: ATI Radeon XPress 200

Now look for information on ATI's Radeon XPress 200 chipset.
For this we can go back to Wikipedia once more,

http://en.wikipedia.org/wiki/Ati_radeon_xpress_200

Reading the top sentence in the first paragraph you will note,
".......Pentium 4, Pentium D, and Celeron processors, ......using either a Socket 478 processor socket, or an LGA 775 processor socket."

What isn't stated in the first sentence is that it will also support Intel Core2 processors. That is stated on the right side of the page, in the information box under the subheading - CPU Supported

I wouldn't think anything higher than an older E4400, or E4500 though.
The E4400, and the E4500 use an 800MHz Front Side Bus. So does the E5300 Dual Core.

The information box states that processors with Up To a 1066MHz FSB are supported.
I just don't know if there is a BIOS update needed, or if a BIOS update is available, in case it's needed.

Needed to change the voltage, and multiplier, so that a processor with a 1066MHz FSB can be used.

To summarize:

The ATI XPress 200 motherboard chipset, on your eMachines W3502, will support an Intel Dual Core E5300.

Advise:
Do Not forget to use anti-static precautions. Your body carries Static electricity. Static will fry out (Short circuit) computer hardware components.

A Processor is the most susceptible hardware component to static shock.

I would advise buying a cheap $6 ESD wrist strap, from some where like Radio Shack, or a similar store, and using it.
Clip the alligator clip to an unpainted surface of the metal frame, of the computer case. (Computer unplugged from power)

Barring this, make sure you touch the metal frame of the open computer case, before you reach inside. (Computer unplugged from power)
If you get up, and walk away in the middle of working on your computer, upon your return touch the metal frame again.

Make Sure the top of the Processor's case is clean, and the bottom of the Heatsink.
I use an old credit card to scrape both surfaces as clean as I can, then follow with Q-tips dipped in Isopropyl Alcohol.

Usually takes a few dipped Q-tips, as thermal paste is a gooey mess, and the alcohol takes time to break it down.

Isopropyl alcohol is also referred to as Rubbing Alcohol. 91 percent is best, but 70 percent will do. Nix on the 50 percent.

CAUTION!
Isopropyl alcohol is Extremely Flammable! Use in a well ventilated area, with no sparks or flames present.

Use fresh, new thermal paste, never try to reuse old thermal paste, or a thermal pad. Thermal paste properties break down over time, and the thermal paste becomes more of an Insulator, than a Conductor.

Thermal pads are only good for taking off, and flying at the cat.
They're Junk!
(Meooow! Hey watch it dude! You almost hit me with that!)

Thermal paste doesn't have to be Artic Silver 5. A good quality thermal paste, applied correctly, will get you down the road just fine. A 'Mom and Pop' computer repair shop, should have a one processor tube, for around $2.

You Should be okay with the same Heatsink/Fan combo, as the Intel Pentium Dual Core E5300 puts out less heat than a Celeron D 352, or around the same amount.

Be sure the inside of the computer sparkles, as well as the Heatsink, processor fan, and the inside of the Power Supply. Use a can or two, of compressed air for computers.

(Celeron D's are not dual core processors. The Pentium D's are)

Technically you can. You should also compare cache level and FSB between the two processors. You may find that replacing the P4 with the celeron may not be much of a again.

http://www.devhardware.com/c/a/Computer-Processors/Celeron-D-the-Little-Processor-that-Could/

Sounds like a heat issue, pop the side of your case open and turn on the PC, are there fans not moving? Take a close look at your processor fan if there is one.

Hi, according to the Dell website you have a LGA775 socket on your motherboard. Therefore, you can only buy processors that fit into this socket. Here is a list of some offered by Intel that will work: Celeron D 325 2.53 GHz Celeron D 330 2.66 GHz Celeron D 335 2.8 GHz Celeron D 340 2.93 GHz Pentium4 520 2.8 GHz Pentium4 530 3.0 GHz Pentium4 540 3.2GHz Pentium4 550 3.4 GHz Pentium4 560 3.6 GHz Pentium4 570 3.8 GHz The processors that won't work are the ones that are not compatible with this socket. Everytime you look up a cpu it will tell you which socket it is designed for. To buy a cpu you will need to decide: The brand you want. The speed of the cpu that you want. Extras i.e. Hyperthreading, etc. How much you are willing to pay for it. Then you can narrow your search as you stick within your limits. Let me know if you have more questions. Good Luck
