I am running windows XP home on a Dell Dimension 8200, with 768 MB of Ram, a Pentium 4, 2.00Ghz, Bios A09. I run Norton Internet Security and Webroot Spy Sweeper. My drive "c" has 107GB of free space. I have tried installing an Epson Stylus RX620. The computer accepts the software, but as soon as I connect the printer by USB, it crashes to the Blue Screen. I get the usual verbiage, from "A problem has been detected" right down to the point where it reads: "STOP: 0x0000007E (0xC0000005, 0x00000000, 0xF7C9A90C, 0xF739A608), with no further explanation or identification of the error. I have no problem re-starting and getting into Windows. I contacted Epson, who first told me to install without Norton and Spy Sweeper running; I did, plugged in the printer, hit test print and crashed. They then said to go in, thorugh MSCONFIG use selective startup and reboot, then turn on printer. I did and crashed. Rebooted and removed software. They then told me to go into the BIOS and change USB Emulation to "No Boot" (which doesn't exist, I chose off) and to dis I reobooted, able USB Legacy 2.0, which was not there. I rebooted, reinstalled the software, plugged inthe USB cable to the printer, and crashed. Any suggestions?
