Acer :: Freezing At Windows XP Logo

I have an Acer Aspire 5710Z which originally had Vista but I had it reformatted to XP.

We've been using it for a little less than a year without much problems until about a couple of months ago when it started to freeze at random times at the windows logo (the one with the blue thing scrolling below). So we had to turn it off then on again and then choose the option to start on safe mode, which worked.

So I've tried lots of things to find out the source of the problem. Apparently, it's not a virus. We've tried to disable all the stuff at the startup but it didn't help. I've been looking around forums and stuff but none has given an answer to my problem.

So I brought it to these tech guys from school, who thought that the problem might be with the drivers. One of the guys saw that there were two intel graphics cards (Intel 945 GM driver) showing up in the device manager, like it was installed twice or something. He thought that might be the problem so he uninstalled the driver and the freezing stopped. I tried downloading newer drivers (actually, I'm not sure if they were newer, I think they were the same as the old one) for the graphics and each time I installed, the freezing problem came back. So the last few months, I've been using the laptop without the graphics card.
