Computer keep hanging - graphic card

[sam6312]

Hello,
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.

Thanks~

Sam

-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?

Hmmm, you did turn OFF the onboard graphics ,,eh???

 

[sam6312]

Hello and welcome to the forums
You can disable the on-board VGA by going to device manager>Display adapters,then you should see your on-board graphic card there,right click on it and choose disable.

That i noe and i hav done it, and i am just confused by dokk2 saying 'off', it should be 'disabled'. Though I have done it, it was a futile attempt and did not work as well. So could it be the graphic card faulty?

 

[Maziar]

Could be
Try disabling Aero,if it didn't help, then try installing windows XP and check if it helps.

I have a Windows Vista Home Basic in a primary hard disk, will it be ok to test it on Vista Home Basic? I have tested it on Vista Home Basic and it still happened, so does that says anything?

P.S. , I bought a second-hand Inno3D Nvidia 7300 LE PCIe graphic card from a shop, which is made in 2007.

 

[sam6312]

Oh ya with a faulty graphic card, will the monitor even display anything?
