you might check bios setting, processor throttling may be turned off, or it may well be a kernel or a virus issue (i assume some viruses care about the desktop enviroment). i suspect, slightly, a virus as they are usually resource hogs, which makes them easilly detectable to someone who knows how thier machine normally runs. note that some viruses/exploits hide from the system monitor. i've repeatedly had one in the past that shows up with no name sporaticly using the kde system monitor, and the 'OWNER" is listed as "root-1", which is impossible to search for as all the search engines insist on evaluating the "-" character as "any puctuation etc.", meaning they'll all return as if you said "root 1", meaning any page with "root" and 1 on it somewhere, weather you use advanced search or just quote it. it's spooky, when it was a problem i just nuked and repaved root. i'd love to know more, but like i said all of the search engines evaluate quoted text to some extent. gone are the days when you can enter a random part number and actually find pages associated with it. when i've detected it was because the machine seemed slow. it uses a lot of resources and makes the machine feel slower. -- The Power Of the People Is Stronger Than The People In Charge. 26.
