8800 GTS (?) driving along in my automobile (wirby) no particular place to go.....i step away for a minute,,, comeback and notice my cursor is a small white puff of smoke set where my sight is,,,then my monitor "flashes" and i have what i call an"HTpalet" in various places on my screen,,, one corner is 2 or 3 rows of small trees, another corner is all the town street signs arranged in a couple of rows. a metal rail fence with a gate set across my screen. I log off and reboot a couple times.. same thing but now my screen locks up...now when i log on to the computer,, when the black command screen comes on for bios setup,,it's a bunch of garbled numbers, letters and characters and when the desktop comes up,,i have a series of vertical dashed lines across the screen along with the desktop icons,,i took vid card out,, cleaned it..reseated it to no avail. and trying to continue on to Aces High,,it just locks up after clicking the desktop icon,,,,ideas?
