How to know if I can change my PC's graphics card.

Hello

Yes, it will work; there is indeed a PCI-Express on your PC's motherboard:

re
I confirm that the integrated graphics card is indeed this one
I confirm that you will need to add a graphics card in addition
I confirm that you do have a PCI-Express slot
I confirm that you can indeed put a daughter graphics card in this slot

That said: according to Djo, because like I said before, I don't know games, even by adding a graphics card, you will only be able to play your games at low resolution, which basically means that even by adding your graphics card, and even a very good one, you will still have a PC that is too weak to play... I mean, to play satisfactorily

So the question arises: to invest in a graphics card, over €150 (and I'm not talking about shipping), or to wait for little Santa Claus, the holiday gifts and all that, and to buy yourself a PC, that you will have assembled, according to your budget, avoiding ready-made branded PCs... which are already obsolete or that inevitably have a flaw at the very moment you buy it

By assembling your PC, you can already recover your hard drive, or at worst your case

But you will need to change the motherboard/processor/RAM and possibly, if the processor does not include graphics, add a good one, all compatible of course, and plan for at least two partitions: a wise choice in case of a bug on partition C or Windows

Ha!! Don't forget that you will also need to add a system; either you buy it beforehand (the Windows of your choice), starting at €95 for Windows 7 Pro, or they install one for you but it will be with an OEM license... still!! I have nothing against OEM licenses, but for me, I prefer standard licenses, a personal preference that is my own..
On the other hand, you will have the undeniable advantage of having a nearby customer service, a recognized shop, a PC that reflects you, and the CDs of your components...

First of all, thank you for your response, but I'm the biggest noob in the world, and what is a PCI port? What I know is that when I look at the properties of "Intel(R) G41 chipset," I see LOCATION: Bus PCI 0, device 2, function 0.

But is it possible for the ATI Radeon HD7750 to work on my PC?

You absolutely need to open your case and check your motherboard, what ports you have on it

What motherboard do you have? (name/brand/reference...)
To find out without opening the beast, you can load maconfig.com or speccy, which will list your hardware in a handy summary (you can print it) or even everest, but for some elements I find it more limited in information.
In any case, it's always good to have detailed information about your setup, it helps make the right choice among the options available and to avoid messing things up when you want to update drivers, for example
And you'll have to open your PC sooner or later, unless it's still under warranty... if that's the case, check the conditions of that warranty.

It seems that your card is an Eton-GL6, which is the name used by the HP manufacturer.

The original name would be Foxconn H-I41-uATX, but it's possible that HP modified it to their liking... and that's quite likely.

Maximum of 2GB of RAM per stick, 4GB maximum in total;
be aware that even with 4GB of RAM, only 3GB will be visible under 32-bit systems, that's normal.
*One PCI Express x16
*Two PCI Express x1
*One PCI
*One PCI Express x1 minicard socket
So as long as your PCI-e x16 slot or at worst PCI-e x1 is free, you can install your graphics card.
However, is it worth the cost (100€ still!!) with that?
Pentium E5400 (W) at 2.7 GHz (95 W)
*800 MHz
*Socket AM3
Not being a specialist in processors or gaming, I can't say for sure, but I do have my doubts, even if neither Call nor Battlefield are among the most demanding.
Wait for more specialized responses.

Thank you for responding to me. If I understand correctly, the HD 7750 will be the best card for my PC; I won't be able to buy a better one?

But I should add a graphics card or replace the one I have because I think my graphics card is soldered to the motherboard.

When I type my PC's name on the internet and check its specifications, it says the graphics card is an Intel GMA x4500. It has 4GB of RAM (my PC is 32-bit)...

Otherwise, I'll use maconfig and I'll post the screenshots...
