How motherboards work

When you press the power button on your computer a signal is sent straight to the motherboard. The motherboard asks the power supply for 12 volts and the bios and chipset wakes up. The processor memory graphics card and other chips start to wake up and the image is displayed on the screen via the graphics card. The motherboard has two chipsets north bridge and south bridge, its also has the graphics card BGA chipset but lets just deal with the most important ones. The north bridge is usually the larger of the two and handles the communication between the processor and the memory. It works much harder than the south bridge chipset. this is one reason why the northbridge chipset will burn out quickr than the southbridge on the motherboard. The south bridge chipset looks after the graphics card sound card wifi, ethernet to some extent and any other peripheral component interconnect cards,PCI.

The processor is like a large calculator that has to work out unbelievable amounts of calculations of around 2 billion per second. It gets very very hot, in fact if you touch a processor without the heatsink on you will get burnt, be warned. Hence the processor requires coolant. heatsink paste will help with dissapation. As these motherboard chips can die sometimes we recommend using a good repair company. Thats why we believe if require computer repair always seek an engineer who understands how motherboards work.

Overheating and switching off

fan

Overheating of computers and laptops is a very common fault. The problem lies usually with the fans. On a computer the heatsink and fan will usually cost between £10 – £20.

On a laptop the problem is usually not being able to get your hands on the correct fan for your system. To the left in the image is a few laptop fans we have taken from laptops. These fans can get clogged up with dust and cause the laptop to overheat and switch off. Overheating can be caused by blocking the fans with bed covers or if there is excessive dust in the fan filter area, this will cause it to switch off. The laptop switching off may be annoying but its better than overheating and blowing up !!

For all overheating issues please ask us for advice.

Computer hard disk broken

The hard disk is the hardest worker in your pc. The hard disk spins very very fast and spends all day reading and writing and copying and pasting and searching files that sometimes , it can get very hot. The heat generated can cause it to fail. The most common cause of failure is if you pick your laptop up with one hand. The hard disk is usually placed to the lower left of your laptop keyboard, and thats usually the place that laptop companies place thier hard disks. That sadly is the area that most of us, when the laptop is on, will pick it up. You will be squeezing the hard disk that is in your laptop. Pick your laptop up with 2 hands and save your laptop hard disk. This problem will not usually occur on a tablet computer this is the benefit of the new tablets out on the market. Tablet repairs are quite rare these days.

If your drive has failed you will need to try to get the data off of it. If you cant you will need to replace the hard disk and reload windows. For all hard disk errors call today for free advice.

Software problems with windows

admin — Sun, 07 Aug 2011 15:28:18 +0000

People often ask me the question, whats the difference between hardware and software? Well hardware is something you can touch, and software is the program inside the hardware. Sometimes because of the hardware the software gets corrupted. Like windows. Windows might have some files missing or corrupted and so how can it load the program if files required to put an image on the screen are missing or corrupted?. If files are missing or corrupted , the hard disk will need to be removed from the pc and the data retreived. Then then the hard disk will need to be wiped, the software ie windows will need to be reloaded. The next step is to put our data or saved files back onto the pc. A software prolem may be caused by a virus or even shutting the pc down by using the power button. This is not the best way to shut down the pc. Ou may need to call a company for pc repair. Whoever you call, make sure that they can save your data, tell them how important it is to you. Some companies offer no fix no fee services.
