Motherboard compatibility acer gx-781

I'm looking to upgrade my current processor from an Intel Core i5-7400@3.0GHz, but not sure if my current motherboard can handle it. 
I've got an acer gx-781 with 8gb ram

I don't have a clue about this stuff, so any help would be appreciated

    You can upgrade the i5 to an i7-7700 series 3.6GHz cpu. For most users, this upgrade probably won't make much a noticeable performance difference. What are you hoping to accomplish with such an upgrade? The biggest speed bang for the buck would be to replace the 2.5" HDD with a 2.5" SSD.

    Just as an addition. if you want to upgrade your motherboard to a mobo and cpu that is compatible Win-11 then you have to buy a brand new mobo and cpu and ram or even the 650W plus psu for the current gpu’s, so you will need to virtually upgrade your PC completely

    It looks like the various GX-781 SKUs shipped with 1TB, 2TB or 3TB HDDs and/or 128GB or 256GB SSDs. The motherboard supports an M.2 SATA SSD in whatever size you want and as suggested by far the biggest bang for your buck is to drop a SATA SSD in while cloning the HDD to it. That will give a much bigger speed boost than any other upgrade, way way more than a CPU swap.

    Just like it has been said above, CPU swap won't make that big difference. Replacing HDD with a SATA SSD, if you don't have one already, will bring down loading times quite nicely. It will not make your PC a rocket, but it does help.

    Do you know if you have two 4Gb sticks of RAM or only one 8Gb stick? If only one, getting another 8Gb RAM module should make your PC a bit snappier.

    If possible, I would consider getting or preferably building a brand new PC.

    Thank you for your answer. So upgrading from Hdd to sdd would be the most worth it, for the pc I have. Do you recommend something special?

    Yes. You should first check the mainboard to see if you have a 2.5" or 3.5" HDD connected to #10 or #12 connectors with a cable. You should also check if #9 & #19 connectors are empty. Then we can decide which is the best choice.

    OK. Other than adding more storage capacity, or adding more RAM so you can load more programs and applications at the same time, there's not much more you can do to speed up this PC. While you might be able to find newer mainboards that could be made to fit, bare mainboards will probably cost you as much as or more to force fit,  than simply buying an entirely newer desktop with the mainboard, newer BIOS, peripherals and required PSUs already installed. Sorry, unless you goal is to learn how to make newer mainboard fit and work inside older cases with older peripherals and PSUs, it is not recommended.

    Sorry to bother again. But I realized I wanna upgrade my ram to 16 GB, but what should i buy? I read something about it depends on the Mhz

    OK. You can add two 8GB DDR4 1.2volt 2400MHz or faster  DIMM RAM modules for a total of 16GB. The max is 32GB with two 16GB DIMM modules if you want to go that high but it's overkill for all practical purposes.

    The 16GB kit for the GX-781 is available from crucial at this link for about $75. https://www.crucial.com/compatible-upgrade-for/acer/aspire-gx-781

    My sons had two x 2 gb memory modules, i Bought an 8gb module so he has 10gb. I read somewhere the older 2gb will slow it all down should i remove it so he has 8 gb rather than 10 ?

    No. RAM speed is limited by the mainboard's RAM buss. Not the RAM module itself.

    Most modern systems support dual channel mode when matched pairs of modules are installed, and that allows for about double the data transfer rate to and from memory. So a 2GB and 8GB paired up don't do dual channel, but two 8GB sticks would.
