Well if it is still turning on have you got any other Fax programs installed if you have uninstall them and the try it !!
If you haven't it is either a jumper on the Motherboard or in the Bios that can be the only other reason !!!
Tell me which Motherboard your Dad has and we can sort it out in seconds
Is it the 850 or the 845 chipset!
Just give me the first group of the bios if you are not sure it will show it something like :-
GB85010A or HV84510A when it first boots!!!!!
CD-ROM ---- Consumer Device, Rendered Obsolete in Months !!!
The Definition of an Upgrade: Take old bugs out, put new ones in !!!
What do people mean when they say the computer went down on them ???
