I urgently need help regarding my mobo.
Cpu-z shows my mainboard as
manufacturer - LDZU ELECTRONICS CO. LTD
model - I945 series
with intel chipset.
My cpu is an Intel celeron 331 (2.66 ghz) (codename prescott)
package - Socket 775 LGA

Now, my question is will i be able to put a new processor(like intel core 2 duo, quad) in my motherboard..

My e-id is indurkar.akshay@yahoo.com
Please please reply asap, as u guys are my only chance..

Also, can u guys please tell me which is the best value processor that'd fit in my mobo.plz plz, that would be so helpful.
The budget for my processor is 7000 indian rupees (around $130)
please please rply fast.
Or contact me on my email id..
Thanks a lot.

Your Motherboard has a Socket 775 LGA which supports the following processors:

Most of the core 2 and quad processors are highly priced than your budget.I think it would be better
you contact you local dealers who have a more correct price.

To know more about the prices in indian rupees i recommend you to visit sites:

Well, the motherboard looks like it's based off the Intel 945 chipset, which apparently does not support any Core 2 Quad processors, only the older 65nm Core 2 Duo E6000/E5000/E4000, Celerons and Pentium Ds. Thus you'd probably be best getting a Core 2 Duo E6600 or something similar.

why would you say that the motherboard does not support any core 2 quad processors,if the motherboard has the same socket of the cpu?

Motherboards have different characteristics apart from the socket. For example, some motherboard can handle higher TDP ( Thermal Design Power ) which is the measure of the CPU's power rating.
The best way to know which CPU's are supported by a certain motherboard is to go to the manufacturer's website and check
"CPU Support List". But you need to know the complete motherboard name which unfortunately for the OP does not seem to be a popular brand so I can not find CPU support list for the exact mobo. Without this, the OP may have to rely on intelligent guesses from experts.

You just said the point about the TDP,i know that unless your motherboard has certain TDP rating equivalent or greater than the cpu's TDP you can't upgrade to new cpu.

But how come the motherboard manufacturer would provide any socket without providing the supporting cpu TDP for the largest available line of cpu?

Also i think there would be bios updates,(just like when the thuban were released and bios were updated to support the six cores by the various motherboard manufacturers)then why would there be any problem if someone consider cpu upgrading to any same socketed cpu.

As I mentioned, socket compatibility is one thing. The TDP is the more important limiting factor. A quad core and an X6 at least will have 125w TDP ( save for some X4 that have 95w TDP ).
Now why would motherboard manufacturers build mobo's that will not support higher TDP, I think this maybe because when they build the particular motherboard model, the highest CPU model available at the time which is the C2D and incidentally, they do not require so much power as quads or hexa. So there you go. Besides I think building higher TDP motherboard will require more expensive parts ( maybe a tiny wee bit) so it is just a matter of cost effectivity.
Now most motherboards are built with ability to handle 140w and with AMD effectively cutting down the TDP of the Hexa to 125w, the trend will be that even Octa's when they come may not exceed 140w making even more board able to handle these in the future.

To the OP, when did you buy your computer, as I had a 945G mobo also, but it couldn't support any thing more than say Pentium-D, where as my friend bought a PC with 945G mobo but about a year later and his supports upto Pentium Dual Core, so if you bought your PC like 2-3 years ago, possibly your board may support C2D's/C2Q's.
Looking at your specs, I don't think it does...so no upgrade option for you :non:  , you should just change the whole thing !!!
But, just to make sure, contact the board manufacturer or website to see the CPU support list for your PC.
