You actually got a tech at ASUS to help you? Ha
When I had problems they never returned my emails...maybe its me.
Anyway, I am sorry that you have to return the MB/CPU. I didn't know you were using Win 2000 as an OS and that it does not allow you to boot floppy.
Since I have never used Win 2000, try checking out the Win 2000 forum in the future. You might pick up something good.
For now, if you have the intent on sending back the MB/CPU, I would format the drive (s) using a program called Wipedrive.
You mentioned earlier the computer might have a bug? I have had the worst of them and Wipedrive cleaned my hard drive so good Mr. Clean would approve.
Sorry, I try to inject some humor so you don't throw your computer out the window or worse.
I am serious about the program though, but you must have all re-install programs available. When I say clean, it cleans...everything. Check it out.
