And I'm not talking about temperatures. OKAY - Start computer and boot up. OKAY - Launch an application (e.g. GT) THEN.... (after a few mouse clicks) - Monitor freezes up. CPU Usage shows 100% (with Hard Drive still clicking away slowly) - Moments later the Keyboard freezes up. - After futile mouse clicks, the Monitor screen goes white - but still shows top line above Menu Bar ("Glock Talk - post New Thread - Netscape Browser"). - Minutes pass and screen and keyboard function returns. Then, CPU usage fluctuates breifly between 17% - 23% BEFORE SPIKING again up to 100% and repeating the cycle. ACTIONS TAKEN - Using Zone Alarm - Using AVG (anti virus) - Ran Windows Disk Cleaner - Ran Trend Mirco Virus checker - Ran ErrorKiller (registry cleaner) - Ran Adware Alert - Ran Ad-Aware SE personal - ATF cleaner RESULTS No change. :-( What is my next step? Thank you.
