You have not really given us much to work with have you?
Even when you rejected the previous post you didn't add any comments about what was happening with the CPU Fan so I take it that things are working right?
How old is this System? You mentioned a 20 GIG drive which is well below the smallest limit that can currently be bought so I'm taking it that this is an older system right?
Start off by testing the Power Supply and if you have another one swap it out and see if that improves things. The next obvious thing to do would be to download a HDD Testing Utility from the maker of your HDD and test it in DOS. These Utilities generally run off a floppy and have their own DOS program so that they can perform the necessary tests on the HDD.
When you replaced the HDD did you Clone it or Reload the system?
If you cloned it you could have transfered a software problem straight to the other HDD and be no better off and if you didn't Clone the Drive how did you get Windows to load if it's shutting down every 10 minutes or so?
Most people here are more than willing to help you reach a satisfactory fix to your problem but we do need information to help you. We could be dealing with anything from a 286 on wards running DOS or WIN 3X to something much more powerful running XP or even one of the Nixes it's very hard to answer a question without the necessary information. Also if you're using an AMD CPU and have overclocked it that could be your problem as well but it really sounds like a heat related problem so if you have a P3 or Socket 370 M'Board pull off the Heat sink and make sure that's it's on the right way and not allowing the socket to lift it off the CPU because the Heat sink is incorrectly fitted.
