Digital BW, The Print

I'm going to look in multiple spots for a solution but clues will be 
much appreciated.

Got the Photoshop 6 upgrade last night, installed. fine.
This morning out of curiosity I switched screen settings
Control/display prop./settings/color - from High color 16 to true 
color 32.

Shut down and restarted.

When I restarted I was unable to start PS 6 or PS 5.
Unable to log on directly to www.adobe.com but can come
in through the backdoor.  Also couldn't access Photoshop
Elements or Canon Zoom browser.

I can access _Photoshop 4_ (and printed) MSword and obviously visit 
other websites directly.

Exact error message...

Red circled X followed by 
"Unable to continue because of hardware or system error.
Sorry but this error is unrecoverable" with a Quit button.

System is Win98se, Pentium3 Display is a Dell P991 on
32MB DDR NVIDIA GeForce2 GTS (not that that means something to me).

Will be looking for solutions?!?

TIA,
