Computer keep hanging - graphic card

I m new to dis forum and hope to get as much help as possible.

I have recently installed a geforce 7300 le (256mb) pci-e card, installed the latest driver and my aero for my Windows 7 Ultimate 32-bit was den enabled.

However, my computer keeps freezing and I hav to switched it off through the on/off button by holding it for about 10s instead of shutting down. It juz freeze randomly whenever I am browsing the net or stuff. For example, when I refresh the Windows Experience Index and when they are rating, it just freeze halfway through and I got to off the com through the on/off button.

Windows will load but after it load, it will freeze after a few minutes. My computer only freeze when I use the graphic card but when I remove it and use my onboard graphic(SiS Mirage 3), it works perfectly fine except that the graphic is really bad with no aero.

I have tried to reinstall the graphic card and the drivers but to no avail. I also reinstalled windows 7 ultimate but still failed.

My motherboard is acer f671cr and I got a 2gb ram. My processor is Intel Pentium D while my model is Acer Aspire SA90.

This problem is making me go crazy and please reply asap as I am going to exchange the graphic card for another soon if I dun fix it.



-EDIT- I did disable my onboard graphic (SiS Mirage 3), but still failed. So could it be the graphic card faulty?

-EDIT(2)- Btw, the graphic card I bought was a second-hand Inno3D Nvidia 7300 LE 256mb, 64-bit bus , which was made in 2007.

-EDIT(3) PS. Could it be overheating cus it is quite hot when I touch the graphic card?
