Any microATX LGA775 motherboard with a chipset that is compatible with the CPU model you have, should work as a replacement for that board, but the problem is this is a VERY old design which hasn't been produced in manufacturing for AGES, and you are only likely to find one reasonably priced if you look for used boards. The problem with that is, you have no idea what kind of condition it is in or if it even works, and if you think Ebay is going to help you with a dead board from a platform that is 14 years old, I assure you, they won't. So it's a very real risk.
You aren't going to find any NEW replacement boards, and if you DID, it would be NOS (New old stock) that has been sitting around for years and years and will likely be EXTREMELY expensive, far beyond the actual value of such of a board, and not worth entertaining.
Not to mention, at this point this is a waste of money. You would be far better off to scratch the whole thing and start over with something new. Even the most basic, cheapest of modern systems will GROSSLY outperform anything that system was ever capable of.
Something like this, plus add the case of your choice (Any microATX or mid tower ATX case should work fine), would give you like twice or more the performance of that old C2Q system and additionally would be upgradeable, whereas what you have now is not.

What is the rest of your system spec:Cannot find a G45T AM2 V:1.0 for weeks. What other motherboards can replace G45T AM2 V:1.0, please?
Thank you.Well, so I think you are out of luck though because upon looking more closely it seems that the board used in that build is proprietary and has an Acer defined form factor that is not comparable with any other "standard" form factors. That means that without some moderate to heavy custom modifications to the case itself, as in adapting the rear IN/OUT panel and changing the location of the motherboard standoffs by drilling and tapping new receiver holes for them so that they will line up with those used by a standard form factor motherboard (mATX, ATX, etc.) then any board you buy isn't going to work in that case, and even if you DO that, you might encounter other problems with fitment. This is always a big drawback from using proprietary systems like many of those sold by Acer, HP, Dell, Compaq and other prebuilt manufacturers.
It's something they did on purpose because they don't WANT users replacing their parts with other aftermarket parts or being able to upgrade, since that cuts into their sales of new systems when a user realizes it's TIME to upgrade. It can be done, but it isn't going to be easy or cheap, and that's assuming you CAN find a board. Now, I can give you a list of boards that will work with your CPU if that's something you want to look into, finding a used board etc., which you might be able to find for cheap although it's a roll of the dice on whether it has problems or not, if you want to give me the model of your CPU.
Thank you.What is the rest of your system spec:
CPU, memory, GPU, PSU, case in particular.
Thank you.Seems that board was only used in the Acer Aspire M5700 Series, which I think used a proprietary mATX board and case.
Actually, that power supply IS a standard ATX power supply, but the standoff pattern on that board is not the same as a standard microATX motherboard, so it looks like that at least IS actually proprietary. Looks like it has most of them, possibly, in the right place, but the lower right corner on your board does not have a standard through hole for a standoff. It simply has an alignment hole for a push pin to snap into and is not lined up with where the remaining standoff would be if it were standard mATX.
