good diagnotics tools for processor & graphics card sought
I am trying to fix a compter which used to run Windoze and regularly simply freeze up. I tested under Knoppix and the same thing happens. So does not seem to be OS -related. I ran MEMTEST-86 for over three hours and no error was reported. So the RAM is out. Since the problem occured when the hard drives were not mounted, they are also not the cause of the problem. That leaves me with either the processor, or the graphics card (I doubt that the soundcard is responsible). Speaking of the proc (a Pentium III - Coppermine - 800MHz, 256MB cache) - it is not overheating as its fan words fine and there are three more fans in the box.
I am unable to trigger the error, it seems intermittent.
Could you reccommend a good diagnostic tool for diagnosing the graphics card and processor? Ideally, something I could run on Knoppix, but otherwise any application existing for Debian is fine.
