Troubleshooting Tips for a New Motherboard
Missing operating system on hard drive.
| PROBABLE CAUSE | DIAGNOSIS | SOLUTION |
| CMOS setup has been changed. | Run setup and select correct drive type. |
Screen message says "Invalid Configuration" or "CMOS Failure."
| PROBABLE CAUSE | DIAGNOSIS | SOLUTION |
| Incorrect information entered into the configuration (setup) program. | Check the configuration program. Replace any incorrect information. | Review system's equipment. Make sure correct information is in setup. |
Screen is blank.
| PROBABLE CAUSE | DIAGNOSIS | SOLUTION |
| No power to monitor. | Power connectors may be loose or not plugged in. | Check the power connectors to monitor and to system. Make sure monitor is connected to display card, change I/O address on network card if applicable. |
| Monitor not connected to computer. | See instructions above. | |
| Network card I/O address conflict. | See instructions above. |
System has no power at all. Power light does not illuminate, fan inside the power supply does not turn on, and indicator light on keyboard does not turn on.
| PROBABLE CAUSE | DIAGNOSIS | SOLUTION |
| Power cable is unplugged. | Visually inspect power cable. | Make sure power cable is securely plugged in. |
| Defective power cable. | Visual inspection, try another cable. | Replace cable. |
| Power supply failure. | Power cable and wall socket are OK, but system is still dead. | Contact technical support |
| Faulty wall outlet;circuit breaker or fuse blown. | Plug device into socket know to work and test. | Use different socket, repair outlet, reset circuit breaker or replace fuse. |
What Are The Parts And Functions Of The CPU?
The CPU, or Central Processing Unit, is a small silicon chip which runs the whole computer. It is also known as a microprocessor or processor, this terminology has been around since the 60s. It is the heart of your computer and is located on the motherboard as an integrated circuit containing millions of transistors and other electrical components. .
It is made up of various parts, the Control Unit supervises the operation, fetching software instructions from memory and coordinating the order these instructions are carried out. The Instruction Decoder deciphers the instructions it receives from the operating system and application software and performs various calculations, comparisons and computations in its Arithmetic/Logic Unit (ALU). The ALU can perform addition, subtraction, division and multiplication as well as comparing greater-than, less-than or equal-to conditions.
The processor has a Program Counter which tracks new tasks as they are picked up, although certain instructions can cause the CPU to execute jobs out of sequence.
Inside the CPU are Registers, which are special storage locations. The data they contain can be accessed much quicker than other memory; they either store the computer's current instruction or in the ALU, the accumulators store the results of operations being calculated.
Finally, the Processor has a clock which acts as a heartbeat, releasing an electrical pulse at regular intervals, it is by this that we measure the speed measured in MHz. The function of the processor parts together is made up of four repetitive steps which are known as the Machine Cycle. The Control Unit fetches data and instructions from the memory and deciphers the code, then the ALU executes any calculation and finally stores the result in memory.
