Advice 1: How to fix processor

The CPU is an electronic device that controls the operation of the computer. The processor executes program code and defines the functions of the computer in processing information. Structurally, it can be made in the form of an integrated circuit on the motherboard or the electronic component.
How to fix processor
Instruction
1
Overheating of the processor leads to unstable operation of the computer. In severe cases, the CPU may malfunction. To avoid this, regularly spend prevention system unit. Disconnect the computer from the mains, Unscrew the fastening screws and remove the side panel.
2
If the processor is in the form of chip (chip), for heat dissipation radiators and coolers. The radiator looks like a battery made of aluminum or copper plates mounted on the surface of the CPU. The cooler is a small fan attached with screws to the radiator. Put the vacuum cleaner on blow and blow with air to clean the dust all devices of the system unit, including, fins.
3
To improve heat transfer between the chip and heatsink use special thermal grease. If the thermal paste dries out, its conductivity decreases, and the processor starts to overheat. Carefully remove the heatsink and wipe the contact area with cotton wool soaked in alcohol. In the same way, clean the surface of the chip. Apply a DAB of paste with a diameter of 2-3 mm on the radiator and apply a thin layer to the surface. Put the radiator into place and secure.
4
The connector on the motherboard, which is inserted into a chip CPU called the socket. When you try to install the CPU into the socket pins of the chip can bend or break. To align the output, use a narrow solid object with smooth surface, for example, a metal ruler or a medical needle.
5
If the leg (contact pin) broke off, you can try to glue it. Insert the correct plug socket, cut the copper wire of such a length that it slightly rose above the surface. The pad of the chip, which broke off the conclusion with a needle or toothpick, apply a drop of conductive adhesive "Contactor" and gently insert the CPU into the socket to ground with glue, tightly pressed to the "prosthetic" leg.
6
Watch carefully to "Kontakty" have not got on the other pins of the chip, otherwise there will be a short between them. Again repaired to remove the processor from the connector is not necessary – leg can be broken off again.
7
If you have a non-working CPU, you can use its parts for repair. Separate from him one of the conclusions and stick to the CPU, which is trying to recover. A thin needle of suitable diameter may also be "helpers". With wire cutters, cut desired length, zarovnaya a file wider edge part and stick the pad to the CPU.
Note
Broken conclusion can be soldered by soldering iron or soldering station, but there is a risk of damage to core due to high temperature.

Advice 2: How to fix the motherboard

The motherboard can fail due to power surges, faulty power supply, through the fault of the owner or was just old. This failure promises destitute to the owner of the computer for a long trouble in a government building – in that case, if he will not be able to cope on their own. But you can try to repair the parent fee on their own.
How to fix the motherboard
You will need
  • liquid rosin and solder;
  • - soldering station or soldering iron with a fine tip and adjustable heat;
  • - a scalpel;
  • - tweezers.
Instruction
1
First you need to make sure that failure came the motherboard. Rent from a friend a known-working power supply. Disconnect the computer from the mains, remove the side panel and disconnect your power supply from the motherboard, connecting is OK. Connect the electricity and hit the Power button. If the computer is started (on the Board lit up indicator, spun the CPU, the dynamics of a single short audible signal), then the problem is in the power supply.
2
If nothing has changed, you may have a defective motherboard. If the warranty on it has expired, return the unit to seller for repair or replacement. Otherwise, try to understand the cause of failure to lose anyway, nothing.Get the parent fee from the housing by unscrewing the screws that it is secured. Place the device on a table and inspect. The most frequent cause of failure of electrolytic capacitors become small cylinder coated on the top side cruciform incisions. This end should be flat. If the top of the capacitor swelled or charge around him dripped the liquid you found the problem.
3
Better to change all capacitors of the same type, even if failure came only one. The capacity of the new capacitor should be the same, the voltage can be higher. For soldering it is better to use soldering station – less likely to damage the charge and elements. If this is not possible, find a desoldering pump and a soldering iron with a fine tip and adjustable temperature. Secure charge vertically. Alternately, remove all the old capacitors - to do this, gently warm up the soldering on the back side of the Board, the capacitor with tweezers.
4
To put new items, you need to release from the tin holes in the Board. Warm the area with a soldering iron and try to remove the tin suction. If that fails, point the hole thin metal rod, holding it with tweezers and warm up the soldering iron, pressing down. In a pinch, you can use the drill with a thin drill.
5
Mounting legs of the capacitor into the holes of the correct polarity – the "plus" marked on the body of the instrument, and on the Board. Dilute the findings of the electrodes on the reverse side of the Board for stability, cut off excess with wire cutters. The heated soldering iron leg oil liquid rosin, then apply a bit of tin.
6
If the inspection fees you find damaged wirings carefully narrow with a scalpel blade or clear varnish on both sides of the defective area. From copper cable remove the thin Postings, cut a piece the desired length. The ends of the wiring and cleaned the place on the track will saladita and carefully solder. This method will help in that case, if the damage is not too deep: motherboard – layered device. The inner layers of the repair will fail.
