So, you want to upgrade the GPU? Chances are that you cannot, as the GPU is soldered directly onto the motherboard in most laptops.

Laptop graphics chips are generally not upgradeable. There are a few exceptions, but in order to figure it out we need to know the make and model of your laptop which you did not provide. Also, your title reads "Nvidia GeForce 5750" and Nvidia makes no such card.

Please show me links to these "choices". As I already mentioned, NVidia does not make a 5750. So either you have the wrong card or you are getting played. Not to mention that buwish and I don't think that it's even going to be possible.

the download of a new driver was an executed action, which didn't seem to improve in any aspect. Well, I just would have this last question. So. There is no way of making this possible? I cannot enhance my PC performance in any way? I did realize that there was no such Nvidia card. Probably this shall be my last question. Thanks for all the help you guys have brought to this site. Thank You.

ok but that does not answer my question thanks for posting anyways
