I purchased a Pentium II 450 MHZ last year, and during the boot up it would say pentium 450MHZ. After a problem where my pci bus driver disappeared , I noticed that on boot up it would say pentium 300 MHZ. when I run hwinfo /ui it says that I have a pentium pro. the pc runs fine I'm just curious why my 450 MHZ boots up saying 300 MHZ.

If everything is running normally, your machine should be running 450 MHZ.  Check your motherboard manual.  Some MB's require jumper settings for cpu clock speed and ratio.  Your clock speed should be 100 MHZ for the clock and 4.5 ratio.  If yours is set by jumpers, locate them and one by one remove and reinsert them which would clean of the pins, should there be a continuity problem.

Some MB's will auto detect the processor speed.  You would verify this in the BIOS setup.  Since you said that your CPU is running 300 MHZ, the clock frequency dropped to 66 MHZ.  Again, either jumper problems or simply getting into the BIOS and fixing it.  FYI, your PC will run fine at 300 MHZ, but you didn't pay for that did you?  An interesting fact is that there's no phyisical difference between 300 MHZ or 450 MHZ chips.  It's a function of sorting out those that are able to run faster without failure.

Thanks AJHanks
I went into the bios setup and changed the clock speed and ratio. and it worked. What could have caused this? I never went into the Bios before? .....virus?

There are far too many things that can go wrong that could change BIOS settings. Some examples are: unexpected power loss during boot up, software installation that may have cause a crash. The list is endless.  I seriouly doubt that its a virus.  Viruses get blamed for a lot of strange computer problems, even it they can'tbe detected.  It wouldn't hurt to get a good anti-virus program just to be safe.  If your computer doesn't show any signs of problems here on then I think you're out of the woods.  If you find the clock speed changing again there may be other problems like the cpu, cpu connections or other hardware issues.  Physical problems are hard to trace and solve.  Since your PC is fairly new your warranty or extended warranty should be exercised to have a professional look at.  I'm not promoting extended warranties, but many good credit card companies offer free extended warranties on products you purchase.  Hope it runs fine from here on.
