Guys - I am not a technical user so this description will lack some detail, I ran into a problem and thought I would post here for suggestions. My machine recently started locking up when browsing. (Toshiba laptop running windows 7 that I have owned for about a year since new) I ran all the tools I could figure. I did a disk check, a virus scan (Kaspersky) , Kaspersky vulnerability scan, checked software level,s missing patches, deinstalled flash and every other thing I could think of. It still glitched and these were hard glitches. Machine became unresponsive to keyboard input. I was forced into a hard reset more than once. When this occurred I was only browsing. No other apps open. Last time this happened I was able to launch the task manager. I saw that media player media synch or service or something (this is the detail I dont remember) was using >20% of the computer cpu and had gobbled lots of space and was growing. I was not synching I had not using Media player since the hard reboot. I ended the piggish process but it kept coming back. I wondered if this were a virus in in disguise so I finally removed Media player. Problem solved, sort of. No more glitches but clearly something happened recently that caused media player service to misbehave. 2 QUESTIONS: If I reinstall media player will it inherit the settings that caused the problem? If so, how can I reset or wipe out those settings to avoid the problem.
