Windows XP
Possible Defects
1.Racirea improper processor (radiator down, fan failure)
2.Sursa damage (swollen capacitors or incorrect voltages)
Identifying the problem
I checked the CPU heatsink and fan I saw that move with a very low speed - could be causing the problem because the unit off (possibly due to excessive heating of the processor)
Replacing the source of the problem is resolved but the CPU cooler speed.
Verdict in this case: INVALID SOURCE voltage
The service we are able to test the tester source.
Defect
In this case the problem occurred because the source.
Fix
Remedy was replacing the source, the computer is under warranty.

Possible Defects
1.Memorie moved into the slot (appears frequently in cold months, when there are differences in room temperature)
2.Memorie burned
3.Placa base damage
Video 4.Placa damage (because no video card attached to the PCI-E)
5.Procesor burned
6.Sursa damage
Identifying the problem
Motherboards typically incorporate a warning if it detects a fault
1.Ne atsat ensure that there is a speaker on the base or connector plca Speaker
2.Scoatem memories of slots and video card
3.Pornim computer and want to see if the motherboard emits signals that talking (you have to hear the speaker more beeps if the motherboard, processor and power are okay)
Verdict in this case: NO
4.Resetam BIOS on the motherboard (remove the battery and jumper pins are a CLRCMOS) and retry step 3.
Verdict in this case: NO
5.Inlocuim source and repeat step 3
Verdict in this case: NO
They remained two possible faults: the motherboard and processor
In 90% of the motherboard is defective. If we can, sample processor on another motherboard.

The computer heats up, go hard, stop,
Description of the problem
After a period of about an hour, the computer stops.
It is very hot and hard work.
If not used, and eventually enter stays on stand by.
Features PC
Mainboard: Gigabyte M61PME-S2
Processor: AMD
Memory: 2x1GB DDR2 800 takeMS
Power supply: 450 W 19 460 LPK
Possible and probable defects
1.Radiatorul the processor is obscured by dust
The processor broken 2.Coolerul
Between the processor and heat sink 3.Pasta Thermal aging and cracked
Identifying the problem
Dust is the greatest enemy of the personal computer. Usually, if you know you live in an area with more dust is better to place the computer as high as possible to the floor. Is preferable to keep it on the desk.
In this case, but it was not dust.
I opened the CPU and Heat seemed fine paste.
The problem could be the source (incorrect voltage) from the motherboard (the processor voltage incorrectly) or from a faulty processor.
I checked a source of tension tester and shows all OK.
With another processor system behaves the same.
Defect
In this case the problem arose because of the motherboard that gave the wrong voltage to the processor.
From experience model of the motherboard itself has this defect, entering service many computers with this problem with this model of motherboard.

The computer starts, howl, the screen remains black
Description of the problem
The computer is powered and flashes but monitor remains black howl (or no signal)
Features PC
Motherboard: Asus
Processor: Intel Dual Core
2x2GB DDR 2 memory
Power supply: 450 W LPK 19.30
Possible and probable defects
When a computer is the processor works howl and, in principle and the motherboard.
The problem usually is from memory (damaged or moved in the slot) or video card (damage or shaken)
Identifying the problem
Remove memoirs and video card and reinsert them into the appropriate slots.
If the problem is resolved in the slot means it miscasera. This can happen because of shocks, bumps or large temperature differences.
If not fixed then you should try with another memory and another video card, replacing them all.
Defect
In this case it was faulty memory module (ARS).
Fix
The problem was remedied by replacing the memory module 2GB takeMS DDR2.

Black Screen - Intermitent BEEPS
A common problem is when your computer's screen remains black and intermitent beeps (shorter or longer) are heard from inside of it.
Usualy, when this happens it means that your mother board and processor (CPU) are working properly.
There is a code of this beeps that can help you in identifing the problem:

Usualy, when this happens it means that your mother board and processor (CPU) are working properly.
There is a code of this beeps that can help you in identifing the problem:
| One Beep | Everything works normal and Computer started fine |
| Two Beeps | POST/CMOS Error (checking CMOS settings) |
| One Long Beep, One Short Beep | Motherboard Problem (checking mainboard) |
| One Long Beep, Three Short Beeps | Video Problem (checking video adapters) |
| Repeated Long Beeps | Memory Error (checking RAM modules) |
