Ru HDtach and results come out ok,also have uninstalled disk controller
driver, but to no avail.
This may sound like a stupid question, but why is the cpu sold as having a
fsb of 1000mhz, but in the bios only shows to be a fsb of 200 mhz even
though the resulting system speed with multiplier is correct ??
