this was on my mother's computer just a couple days ago. first it slowed down her desktop n then today it just started dialing her modem every few minutes. i made sure there were no other programs running that would connect to the internet. the random redialing stopped once i ended the process.
Using 80-90% CPU on an old Compaq. Renamed file "pctspkOLD", rebooted, CPU usage now normal. Owner recently left dialup for cable, so maybe it was polling nonstop for dialtone, who knows?

Don't know much about this, except that it suddenly appeared, started slowing my computer by using too many resources and isn't needed for anything used by my PC. I also have a DELL Laptop.
One day it began using 99% CPU on DELL Precision, guessing it runs at higher priority because my app needing 90% got 1%. End Process resolved issue this time.

Best practices for resolving pctspk issues

A clean and tidy computer is the key requirement for avoiding problems with pctspk. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time.
