My first response (after scanning) is to remove the case cover and see if it gets better. I'll also clear the EVENT VIEWER and wait for a reboot to see what shows up.
My system - Older Dell Windows 98- upgrade 120 GB HD/384 RAM Windows XP Home.II also upgraded to a Sounblaster card and a 32 MB ATI Rage 128 ultra video card. AntiVir Personal Edition Anti Virus with Peer Guardian2 and Windows Firewall.
My system has run very well but now it seems to be cutting out and rebooting at least once per session. Could this be an indication that the mother board is going? I had a problem with my mouse freezing up about a month ago but that problem no longer exists. Gremlins in the system. I've run Ewido, Adaware,and Spysweeper and my system is clean. Is there a possibility of another conflict I should be looking into? As always your advice is top notch.
