Thanks for the suggestions OH Smeg.
I have a hard copy of the manual and it seems to be the same as the downloaded version.
I've already reset the BIOS to the default settings and checked the Date & Time to no avail.
I've been using the WiFi driver that came with the system but I'll check online for an upgraded one.
I've downloaded the (new) Dell PC Checkup software and run it twice. This software doesn't pick up on the EEEProm error but the system still runs dead slow and crashes repeatedly.
I've also run (my) Vipre and online versions of McAfee and Symantec. The Trend Micro online virus check locks up my computer. Except for Vipre, the others are accessible from the Dell PC Checkup.
I've even gone back to a mid-February registry backup then updated all the recent Microsoft updates.
I've run Dial-a-Fix as well.
I'm at a loss at what to do next.
Thanks again,
Bruce
