|when i opened the computer case the chipset was too hot.|
You need to explain this a bit more as to exactly what you mean. The chip-set consists of two main chips, the northbridge and the southbridge plus a few support chips. They very rarely get hot, warm, but not hot. the northbridge chip is the one that does most of the work and that can get quite warm. That is usually near the top of the motherboard, hence northbridge.
Do you by chance mean the CPU. That'd the big on with a heat-sink and fan on it and they do get hot which is normal. Touching something in a computer and finding it hot is not a very good fault finding technique. Too hot is a bit subjective, you need to know exactly how hot and most BIOS will have somewhere to tell you ho hot the CPU is.
