Hi everyone,

Could anyone help me? I've a problem with my computer. Every time I use my
house phone, my computer is turn on and the system stops responding. It
won't run very well until I restart it twice or three times and disconnect
it from telephone, what's wrong with that? I've checked the properties of my
modem, there's no checkbox for "allow modem to turn on computer". Here are
My computer specs: Windows XP pro, Generik softk56 modem.

Thanks for helping me.

Look at BIOS "wake up" options. See the motherboard manual for instructions.
 
Look in the BIOS for that feature. It will be listed as "wake on lan", "wake
on ring" or something similar.
 
The BIOS change may cure the power on. But if BIOS power on
is a problem, still, nothing on phone line should ever get to
that circuit. You do have the computer connected to a three
prong (safety grounded) outlet? Your household grounds are
intact? The phone line NID (premise interface connection - a
box that connects their line to yours) is properly earthed to
same ground as electric box?

We are looking for some reason why a phone could cause such
a voltage change as to trigger that BIOS circuit. Normally
phone line is isolated from rest of computer by 2000 volt
isolation transformer and isolation inside an off hook relay.
But somehow your phone line has made an electrical connection
to computer circuits - not good.
 
I just built a new PC and in my BIOS I have a "Wake on Ring" option which
turns on my PC when the phone rings so my software can answer--why would
this be such a problem?
 
'Wake up on ring' is enabled if computer should answer the
phone. That is not a problem. The OP's problem is a computer
turning on due to something that is not a phone ring. When
the phone rings, about 100 volts appears on that phone line.
Modem detects the high voltage and turns on. But when making
a phone call, then phone line voltage is only below 50 volts.
That 'wake up on phone ring' should ignore 50 volts.

But the OPs computer is even responding to 50 volts. So why
is 50 volts acting like it was 100? Therein lies the real
problem. He could turn off the 'wake up on ring' function.
But why is computer seeing higher voltage - or is modem
defective. Either way, his 'wake up on ring' when 'no ring
exists' means something else is wrong with his system or with
the system connections to building grounds. Turning off the
'wake up on ring' only cures his symptoms. It may be a minor
problem - defect in modem - or it may be a major electrical
problem - missing or defective safety grounds in his building.
 
Hi dev, steve, & all,

I've checked the BIOS and looked at the WOL/WOM resume in power management
setup option, it remained in its default seting "disabled". Just for your
information that my problem was when I use house phone it will turn the comp
on not when incoming traffic to a modem. Thanks for your reply.

The phone your using creates a voltage spike in the line when you pick it
up,You'll hear it blip on another phone in the house. modem sees it as a
ring. My $6 hardwire phone does it and the wifes cordless does it. Go into
bios and disable wake on ring .O f course I have to take into account the
fact that my phone company just upgraded my area from soup cans and fishing
line.
