Hi dee_dee 19 and welcome to PCMech.:)
We need your specs. and you need to read through this : http://forum.pcmech.com/showthread.php?t=132409
What you've described suggest a heat problem so make sure your heatsink/fan is fitted correctly and the protection on the bottom of the combo was removed before you installed ( for retail processors) or that you used thermal paste correctly if it's an OEM processor.
