"what could be the problem?"

Please post the make/model of your motherboard. My guess is the heatsink was installed incorrectly (not locked down securely or improper thermal paste application). Another possibility is the new CPU isn't supported, or it may be supported but BIOS must 1st be updated.

We need the board info.

I hope you didn't pay much for the new CPU. If you have a decent board, the 4600+ probably could have been overclocked to 2.8GHz.

Can't get to BIOS Setup after changing the CPU usually means that CPU model isn't supported by the existing BIOS version.

If you put the original CPU back in you should then be able to get in to BIOS Setup and Windows should start okay. You'll then be able to update the BIOS from the motherboard maker's website (that's if they have an update for the 5400+ of course).

You may have bent the motherboard pins which in that case you'll need a new motherboard have a little check you'll know what to look for when you see it

Here is a picture of what bent pins look like, may not be as many as that may be just one or two

AMD boards don't have pins.

Oh yeah forgot he said AMD well their pins are actually on the cpu itself I believe? If there isn't many bent you may be able to bend them back but I wouldn't advise it. But have a look it could be the cause.
