|Sorry but if you want technical assistance you need to provide technical details.|
What are the hardware specifications of your system. Make/model numbers if a namebrand system, or make/type and size/capacity of motherboard, CPU, RAM etc.
Next what were the error messages?
Since this was a new presumably clean installation of the operating system you have little to lose by doing a fresh format and re-install. However with the little information you have provided it is not possible to determine whether you have a hardware, software or compatibility problem.
