By George! I think I've done it!
Abit board, new Montego II Quadzilla sound card; new D-Link ACPI network card; new i-Hub USB hub.
Put them all together, Load Win2K;load all the latest company drivers (Via 4in1; Turtle etc). No problems! Hooray!
Time to load application software. Load Office 2000. Locks up! Steady. Try again 10 times with various combinations of apps, drivers. No go.
Deep breath. Re-format AGAIN, load WinME, new drivers etc.....Load Office. Lock-up!
Deep breath. Re-format. Load Win98 and old drivers. Load Office 2000. Locks up twice but, eventually after a couple of reboots, loads. Upgrade to WinME; load all new drivers. All works!!
Tonight is time to back up the HDD and then try to add all the other USB accessories like printer etc.
If that all works back to the ASUS and build the other system again......
Did I say I did this as a hobby to relax??
