Freeze and random reboot. HELP!

Question

I'm going to try to keep this short as it is a long story.
Recently I reformatted my hard drive and installed Windows XP Professional. After the installation I realized that I do not have the drivers for some of the hardware. I installed all latest drivers off their webpages but only one problem. Now the computer randomly freezes (more likely to freeze if IE or Mozilla is opened) and sometimes on rare occasion will reboot itself. I've searched and checked everywhere and found only little information. Possibly the video cards driver is too new or too old, P/S, general driver defaults, etc, etc. With the help of SIW I found that the P/S and temperatures are all normal, so that can be rulled out. My questions are; Has anyone had this type of problem or know how it can be resolved? And also, could it be possible for my RAM cards to be at fault for the freezing or rebooting?
Here is my setup:
Asus Desktop
AMD Athlon 62 3200+ Processor
MSI K8N Neo MS-7030 VER. 1 Mainboard
ATI Radeon 9550 Series AGP 256M Video Card
again... O/S is Windows XP Pro

Hang in there, these problems can be very hard to diagnose.  Trust me, I know.  I'm having some very similar ones.
Disable automatic reboot in System Properties\Advanced\Performance\Advanced.  This allows you to see the BlueScreen information before you manually reboot.
Try uninstalling all the drivers you recently installed.  Install different versions of the drivers, either older or newer, one at a time.  Test things thoroughly in between.  Try to document exactly what you were doing and what was loaded when you have the failure.  If you get a Blue Screen, write down all the information.
Post back.
