I should've qualified that I had a video problem when in the browser. Sometimes
when scrolling there was too much for the CPU to do even after a video card was installed.
(That is, I started with the onboard video.) The screen would flash black. I rarely
got a lockup and never got one after the video card was installed. I also installed
an sound card to bypass the onboard sound. I still needed some moderate overclocking
to eliminate problems.
