Have you tried un installingthe entire modem set up ?
orcnxtsdk.dll is part of a Conexant modem driver. cnxtsdk.dll is not a Windows XP or 2000 file.http://www.tech-archive.net/Archive/WinXP/...4/msg06844.html
Concerning the noise; I'm not sure of the first but the second is interesting.
Why does my dell monitor make a frying noise? http://www.answerbag.com/q_view/1163181
It could indicate that the monitor is getting ready to die on you. If it's a CRT I'd suggest you replace it, as it may become a fire hazard.
My laptop speakers are making a frying sound, can anyone explain why?http://freedownload1.com/faq1/14485.htm
i can hear sounds and music but if i turn off the music its making a frying and static sound. i actually hea that frying sound behind the music sounds ect. anyone can help?
Most lilely your microphone is plugged in and active still. Disable it if so. If not, check for other cables, particularly power cables, wrapped around or touching the audio cables. Also check for any damage to the cables.
Some cheap motherboards have badly done "on-board" soundcards, where the other parts of the motherboard cause interference on the soundcards outputs. In my experience USB activity and static noise go together on anything Dell, Gateway, HP or ASUS produce.
I don't have the PC right here at this time, however I will get back to you and post here any thing new, . .
Thank you .
