Help! I recently installed XP Home Ed. On HP Pavilion 7940. I keep getting Blue screen crash when on Inerntet. Always references file ltdmnt.sys, my modem driver.... ErrorS: "DRIVER IRQL_NOT_LESS-OR-EQUAL" Also, just recently had another crash: "An attempt was made to write to read-only memory." I have a Lucent Win Modem, went to Agere Systmes site an downloaded 8.22 driver, seemed to reduce the frequency of crashes somewhat. But it's still crashing.... Also, I have updated to the most recent Phoenix BIOS... Any suggestions, before I go out and buy a now modem???
