I mean test the hardware of your computer. First, check the memory - MemTest86+ is the tool most people use for this. Run it on your system and it will highlight memory problems. It can be found at www.memtest.org - the precompiled versions are tiny and will fit on a floppy (or memory stick or CD).

You might want to download one of those anyway as they both contain MemTest86+. None of this needs you to open the case. P.

HP Compaq dc5800 sff (small form factor) I would not be surprised if the kernel just did not like my motherboard any more. Even after I figure out the kermal panics, the video will still be an issue.> First, check the memory - MemTest86+ is the tool most people use for > this.

My suspicion is that this is a repeat of what sent me to Centos from Fedora. (Yes I know the relationship). I'm told I couldn't install Fedora on a machine because a kernel bug affected precisely one kind of motherboard, mine. I'm also told the bug was supposedly fixed, but I was never able to run any later Fedora on that machine. -- Michael hennebry at web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

You get a lot more problems with new motherboards than you get with old ones.> > Even after I figure out the kermal panics, > the video will still be an issue.They may well be linked.> > > First, check the memory - MemTest86+ is the tool most people use for > > this.

Not even when you got kernel panics when booting the live Fedora did you mention this was a known issue. P.

While I was deciding what to tell it, it started in upiprocesor mode. After reading about kernel option, tried C7 LIve again. Got panic again. Tried again with nosync. Gpt panic again. What got C7 to boot was acpi=off and nosmp. Tried to play the Big Bunny file. Got fullscreen mode, the first and last images and audio. No complaints. Eventaully figured out how to get it out of fullscreen mode. Big Bunny played without the shutter effect. The next thing on my list is to try MemTest86+ with SMP. -- Michael hennebry at web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards
