Can i replace my intel celeron to intel pentium processor?

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

The fastest Pentium 3 that will work in your board is a Intel Pentium III 1GHz chip. Here is a link to the specs:
http://www.cpu-world.com/CPUs/Pentium-III/Intel-Pentium%20III%201000%20-%20RB80526PY001256%20%28BX80526F1000256%29.html

You could also get a Intel Celeron 1.1 GHz but it only has half the level 2 cache size so it's actually a bit slower than the Pentium III 1GHz chip.

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.

(do not attempt to use a CPU that your motherboard doesn't support. It probably won't boot.)

Gigabyte's page for your board (GA-8S661FXM) is here, and you can find the supported processor list here.

No, the Intel (Ausberg) 915G motherboard will not support dual core processors.

The Intel (Ausberg) 915G motherboard uses an Intel 915G motherboard chipset,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4.2FPentium_D.2FPentium_EE_Chipsets

Supports only Single Core processors.

It isn't until the Intel 945G motherboard chipset, that Dual Core processors are supported.

[NOTE*
The Intel Celeron D is a Single Core processor.
The Intel Pentium D is a Dual Core processor,

Intel Celeron D,

http://en.wikipedia.org/wiki/Celeron_D#Celeron_D

"The Intel Celeron D processor works with the Intel 845 and 865 chipset families. The D suffix actually has no official designation, and does not indicate that these models are dual-core. It is used simply to distinguish this line of Celeron from the previous, lower performing Northwood and Willamette series, and also from the mobile series, the Celeron M (which also uses 3xx model numbers). Unlike the Pentium D, the Celeron D is not a dual core processor."

Don't 'shoot the messenger'. I just state the facts.

Check to make sure that both computers have the same socket type, it should be printed directly on the connection for the processor. If the sockets match, you should have no problems dropping the new processor in it. Incompatible processors simply won't fit in the motherboard, so if you can't seem to get the processor to fit properly, it's most like incompatible.

You can find supported processors at http://processormatch.intel.com/COMPDB/default.aspx

Also, these processors are supported on your motherboard:
Intel® Pentium® D,
Intel® Pentium® 4,
Celeron®,
Celeron® D processor

you may check
1) your Intel pentium 4 3.2 GHZ cpu socket 478 processor #sl7nb what's FSB?( see on the chip surface, if 533 FSB can use but 800FSB could not match your motherboard if which is not support 800 FSB. that's why no display.
2) check RAM stick speed, try to increase a level, for example 266 to 333.
is this helpful please feedback thanks

hi there, for me yes, but up to 1.7 ghz only or lower ghz., as long as it was the same sockette type of processesor. do some test. ty
