Same problem here! We had to stop using that machine due to the frequent
interuptions. The power supply has been checked and also the processor fan. I
am using an ATI Radeon card. Not sure of the series number at the moment.
Please use correct nomenclature. I believe you are referring to the
computer, not the CPU.
A central processing unit (CPU), or sometimes simply processor, is the
component in a digital computer that interprets instructions and
processes data contained in computer programs. CPUs provide the
fundamental digital computer trait of programmability, and are one of
the necessary components found in computers of any era, along with
primary storage and input/output facilities. A CPU that is
manufactured using integrated circuits is known as a microprocessor.
Since the mid-1970s, single-chip microprocessors have almost totally
replaced all other types of CPUs, and today the term "CPU" is usually
applied to some type of microprocessor.
The CPU in your computer was probably made by Intel or AMD.
