Overclocks can be stable enough to pass the Bios but not stable enough to completely boot the OS. Corruption of the OS can occur and best to let the OS try and repair itself(this is usually successful).
Why is it not stable? People with the same motherboard and with the same cpu and stock cooler it worked for them.
It's called the silicon lottery, each chip is of variable quality and overclocks are never guaranteed.....ever. Just because one chip will got to 4.8 Ghz doesn't mean the next one will.
Whaaat?

Intel (or AMD) makes only a few actual chip types, Typical dies will be Quad or Dual core, with or without integrated graphics. Each chip is tested for functionality, what parts work/don't work determines whether it will be a Pentium, i3/i5/i7 etc. Cores and Cache are disabled if they fail testing. In addition the max fully stable clockspeed is determined. All these tests result in a "binned" chip and the model number and type is determined from one of these "bins". High end chips are fully funcional units, low end generally had some issues and are partially disabled (i3, Pentiums). i5's and i7's are nearly identical but for Hyperthreading.
These rules are loose and fast, so....if Intel (AMD) needs more Pentiums (Athlons) this month, they will use high binned chips for low end Processors, this is the silicon lottery. Sometimes you get a high binned chip as your Pentium, sometimes you get crap. And since Pentiums and other entry level processors are the bulk of their sales chances are usually good for getting a decent overclocker...usually.
