Upgrading these drivers are not a problem. (Though I do recommend not doing so unless you are having a problem with your computer.)
A LOT of people buy into the myth that AMD processors cause lockups, but the real (and only) issue was actually that the VIA chipset drivers that AMD processors use were not included in Windows like Intel's drivers. It's important these be installed right after Windows. The reason is that they alter how hardware and drivers interface with the rest of the system, so installing them after your video card drivers and directX don't allow them to work as intended.
When I do a VIA chipset based system I ALWAYS install the newest official 4 in 1s right after windows. In addition the only card I have in the system at that point is the video card. (In standard VGA mode still.)
Typically I do it this way (and have NEVER had any problems):
1. Assemble system, install vid card, ram, cpu, hd, floppy, cd, etc.
2. Enter bios and change ram timing and latency and overclock CPU (if desired). Set ACPI and PnP OS to desired settings.
3. Fdisk and format. (Be sure to enable "large disk" (defaults to yes) when fdisking.) Run a scandisk on HD. There's nothing quite like installing windows to find the hard drive was defective from the factory.
4. Using setup disk, install Windows by copying setup files to HD from CD and then rebooting and running setup from HD.
5. Install newest official Via 4 in 1s. ( I have them and a copy of winzip on a burned cd ready to go. ) If you don't have access to a CD burner to get the newest set, MBs usually come with a CD that includes a fairly recent set. At this point also enable Ultra DMA (ATA) if the VIA busmasters didn't do it automatically. Also set typical role to "network server" for win98 and ME.
5a. If win98 FE, install service pack, Win2k install SP1 and SP2. (I have these on a disk as well. If you don't have them on a disk with all your needed drivers, you should.
)
6. Install direct x, then video card drivers. (They are on that CD you made right?
)
7. Add modem, NIC, and LAST a SB sound card. Install drivers and reboot after each device.
8. Check device manager for exclaimation points and other possible problems. Check "system information" for IRQ conflicts. (Note: If ACPI is enabled (default with win2k and preferable) all devices will be on IRQ 9 or 11. This is NORMAL and CORRECT.)
9. Benchmark system if desired.
10. Install programs at this point.
