Before you begin, some of our software on your PC diagnostic tool to identify potential problem areas download. Ideally, the best solutions to problems using the computer allows "With the double parts division has completed proof peripherals", card, cards or cables. It is normal that the outside support system has problems but is better. Delete unnecessary peripherals (sound card, modem, hard disk, etc.) may differ from unworking testing equipment. In addition, equipment replacement, do not forget the power supply. Watts of power shortage (and V), at all levels can cause intermittent problems, but especially UARTS and HD With. Inspected the motherboard for loose components. A loose or missing CPU, BIOS chip, crystal oscillator, or the chip chipset motherboard is not working. You too loose or missing caps, missing or loose memory chips cache (and SIMM or DIMM) for the bridge can. We refer here to frustration, BIOS configuration settings, saving hours are likely to see. 60% of the time, the system is due to many failures. One is soon to restore BIOS default settings. Next, eliminate the possibility of interference by a bad or inadequate I / O to remove all card except the video adapter card made. System at least for power and one should wait, while production. Card system was a time when the problem happens again put back on. When the system is nothing, the problem is with the last expansion card was in.
RESETTING CMOS
You 'do recently computer flash BIOS, and a need to change is to plunge? Maybe you left''position of the bridge in Flash can be erased because the CMOS. If you jump the CMOS reset and treatment of these methods are not appropriate settings: several applications on our Help Desk Clearing BIOS / CMOS password that we have prepared a standard text with different solutions need to receive.
NO POWER
Changed the power supply (the most used PC) with V in the field test may not adequately / m ohm. Remember: For most work, switching power supply for a floppy disk and memory are less than 1 MEG should be present on the motherboard. If necessary components are present in the motherboard and no power.
PERIPHERAL WON'T WORK
Peripherals devices connected to the motherboard, including I / O boards, (including mice and modems are RS232/UART equipment), fixed disk and floppy disks, video cards, etc. in modern boards, several integrated peripherals are on the motherboard, that is, if you are not peripheral, in fact more to the table .* motherboard should be replaced, the external device through the daughter card has been added. Permission from the Board for some CMOs MB device, which is not to replace motherboard may be an option - but in practice, some tables peripheral costs, more so can not, motherboard with. Also on board for other components of equipment failure may signal a failure cascade.
