error with processor speed

[Jono]

Ive got a really annoying problem with my computer.
When i turn on my computer, at the boot screen it shows me that my computer's speed is 456 MHz yet my processor is actually 1800MHz. When it says 456 MHz, everything loads at the same speed as 456, loading windows XP takes 5 minutes. But sometimes it says 1800 and then it works like 1800 but sometimes it hangs as well. Ive tried everything to remove the constant crashing.. removing/buying new hardware, formatting my hard disks and reinstalling windows XP. I just couldnt figure out the problem! Can somebody tell me what the problem is and how to solve it?
[/list]ow i could solve it?
