Are you running a factory image or a custom install.
If possible run a factory image - e.g using the original restore disks or factory patition. If the problems still occur it's probably a hardware fault. If the problems don't occur, you can rule it's definitely drivers, then do a custom install and install the drivers one by one, till the problems occur. I know it's a huge pain!!
Or if your happy with the factory settings leave it be.
Either way I'd do a reset to factory settings / reinstall the OS if it's custom built.
