Either the L1 or L2 Cache's are turned off in CMOS settings or you are running without RAM (or known good RAM), in the box.
Did you FDISK and clear all known partition(s)? Did you Partition and Format the drive properly? Did you make the 1st. Partition active?
I once had a bad stick of RAM in a box that actually tested good w/ a software testing utility but made the install fail each time tried, however the test MS told me through the KB was to shutt off the L1 & L2 and load windows....Well w/ them shut off it actually did take like half the night, but it did finally install. (Pointed out that the RAM in the box was fine but the CPU had died. (If the RAM was bad in that case the install would have failed the article told me). So I'd look only in those 2 areas. RAM or CPU....Also check the processor fan and the heat sink media. (You didn't perchance use old dryed up heat sink paste or media did you?) Did you apply nice fresh paste?
Good Luck.
