First of all, you need to locate the source of problems. The search should begin by answering the question: how it all began? Was there a time when such a problem is not it? What has changed since then?
- Try to put the latest drivers for all devices installed in the system, particularly paying attention to the motherboard and graphics card. If and so are the latest, you can try to do the opposite and put the ones that are on the disk, which were given with the equipment when buying.
- In the Control Panel in the System Properties see if there is any conflict.
- Turn off all power-saving options, including screen saver (screen saver).
- Try to Setup BIOS to set higher values for memory timings (ie, slow it).
- Put options for "Video BIOS Casheable" and "Video BIOS Shadow" value "Disabled".
- Increase the 8 and 16 bit I / O Recovery Time.
- Remove any overclocking, if something is broken up. You can try to pick up (a little bit, to 0.05 - a maximum of 0.1 volts), the voltage of the processor.
- Check the operation of all the fans, it is possible that some of them failed and the system simply overheated.
- In the BIOS set the AGP Aperture size to a minimum, and turn off the AGP2x AGP4x.
- If there is a possibility that the problem with the hard drive, the BIOS forcibly put him PIO 4 or even 2 PIO mode.
If the above does not help, or for some reason do not fit, then, assuming that the problem has its roots in any faulty device, you can move on to more drastic measures. Removed physically from all system devices, without which the system can work. Leave only the motherboard, CPU, memory, hard drive and graphics card. In the BIOS, disable all that can be: COM and LPT ports, all the Power Options, Assign IRQ for USB (do not touch Assign IRQ for VGA!).
If the problem has not disappeared, check all of the remaining devices: video card, memory, processor, motherboard, and hard drive. The easiest way - to set the device to another machine and see how it will lead yourself out there. If, however, the removal of all unnecessary devices the problem was gone, you have to take turns to put the device on the remote site and after each turn on the system and verify the "well-being". If the problem is in the faulty equipment, then, as a rule, this method manages to locate her. However, do not always have to resort to such drastic measures, often the reason lies on the surface, and presumably problematic device manages to calculate immediately. The best way - Now check it on another machine, and it is better not to one, it is highly desirable to be different from your configuration. If it turns out that the piece of iron is still working, it is necessary to better understand their car. The first thing you should pay attention to which slots with which share the same IRQ. Typically, about it can be found in the instructions to the motherboard. If no instructions or too lazy to dig, you can just try to charge in another slot. It will not work in the case of AGP-graphics card, in which case it is better to find out which of the PCI-slots shares IRQ with the AGP, and see what there is. Incidentally, the board will permutation and if you have one of the slots is defective.
However, regrettably, there are situations when the device A physical incompatibility with the device in, for example, due to insufficient supply. In most cases, there is nothing we can do about it, although there are happy exceptions, when everything comes back to normal after the installation of a more powerful and high-quality power supply, or, as some mothers ASUS'skimi when the jumper is on the mother, with the help of which you can force increase AGP-slot power.
If the problem is rooted in the software, the basic principles of the solution are the same: the removal of all that is possible, and the gradual installation of a back test the system after each installation. Sometimes this method is being investigated very interesting patterns. For example, who would have thought that the installation of PGP program may lead to post POWER_STAT_FAILURE when you turn off the machine? And, of course, always remains a radical method - the complete removal of the old operating system and install a new net. When reinstalling Windows 2000 / XP, be sure to clean the folder "Documents and Settings", the operating system does not overwrite files in it (though threatened), but simply create new directories. Therefore, if you do not clean this folder, then reinstall the system after repeated there will be found such as the directories "User1.USER.000", "Default User.001" and many others. And find out which of them is not always easy.
In case of any problems with specific hardware or software, the best place where to start the search for solutions - this technical support by the manufacturer. You can be sure they know your product better than we do.
And the last. If you still decide to disassemble your computer, be careful and attentive. Be sure to turn off the power of preliminary FULLY computer, ie pull out the plug, because otherwise on the ATX-buildings house the power 5 volts will still be submitted. Do not forget to make sure that the slot in which you want to insert something, nothing, including dust. Because the dust has a specific electrically conductive and may cause short circuits. Before installation, check the correct orientation of the inserted parts.
DIMM stick upside is not as impossible as it may seem.
