Users questions: How my computer will not start it sometimes started in the hardware information of the bottom three lines in red and sometimes initiated after a while the monitor will automatically detect the restart information. . . . . . . Who master to support a move.
Experts answer: is not enough voltage the BIOS battery discharge (recovery BIOS out Factory default) recommended plug about graphics cards, memory, clean up health and polished graphics card, memory of the finger. PC boot no display troubleshooting method (see if there is the capacitance from the drum). Step 1: First check the computer's external wiring is connected to each connection re-insert it again to see if the failure was Not be ruled out. Step 2: If the fault persists, then open the main chassis view and whether the excess metal chassis, the deformation caused by short circuit or motherboard, chassis and whether the charred smell of paste flavor, without burning the chip on the motherboard, CPU around capacitance for damage and so on. Step 3: If not, then clean up the motherboard The dust, and then check whether the computer normally. Step 4: If the fault persists, then unplug the motherboard's Reset line and other switches, light connection, and then short-circuit switch with a screwdriver, to see whether to boot. Step 5: If you can not boot, then use the minimum system method, the hard drive, floppy drive, optical Drive data cord, and then check whether the computer can boot, if the computer monitors the boot screen appears, the problem in these devices. Then one by one over several devices to access the computer, when access to a particular device, failure to reproduce, indicating that the failure was caused by this device, and finally focus on examination of this Equipment. Step 6: If the fault persists, the fault may be caused by memory, video card, CPU, motherboard and other equipment caused. Then use the plug method, exchange and other methods were examined memory, graphics card, CPU and other equipment is normal, if there is damage to the equipment, replacement of damaged equipment. Step 7: If the memory was Card, CPU and other equipment properly, and then discharge the BIOS, using the isolation method, the board placed outside the enclosure, connected to memory, graphics card, CPU and other tests, if the computer can display, and then install the motherboard into the chassis and then test until you find the cause of the malfunction. If the fault persists you will need to board Return factory repair. Step 8: Computer power no display but the alarm sound, when the computer boot time, the system BIOS to start POST (Power On Self Test), when the computer detects a device in a fatal error, the report will control the speaker sound error. Therefore, there may be no show boot report Offbeat failure. For the computer starts without showing alarm fault alarm sound can be the meaning of BIOS to check the faulty equipment, to troubleshooting. Not start the operating system of diagnostic methods are as follows. First check the boot, your computer is started the operating system. If the start operation For system crashes, blue screen or reboot, the hard disk partition table and master boot record normal, excluding the hard disk partition table is damaged, hard disk master boot record is damaged, lost hard drive partition marks the end of such malfunction. Then use the following method for diagnosis. Step 1: First, start the computer using Safe Mode, see the Not able to start, if not start, it may be infected with the virus, the system file is missing, damaged operating system, hard disk has bad sectors, hardware conflict or hardware problem, go to Step 4; If you can start safe mode, you may is not compatible with the system hardware drivers, operating system problem or virus infection cited Played. Step 2: Then run antivirus software, if a virus, it may be caused by a virus, antivirus, restart the computer, if not normal, you need to reinstall your operating system. Step 3: If no virus is detected, you can use the operating system comes with a "System Restore" feature, System Restore, If the system is restored to normal, failure is damage caused by the system. If the fault persists, the device driver may be incompatible with the system caused; then the sound card, graphics cards, network drivers and other equipment removed, and then install the drivers one by one, each installation of a device to reboot the computer, To check which device driver is causing the failure, check out, download the new version of the failed device driver, then install it. Step 4: If you can not start in safe mode, then use the installation CD to reinstall the operating system. If you can properly install the operating system, turn step 7; if the installation System failure, such as crashes, blue screen, restart the system as a result can not be installed, then it should be a hardware problem or caused by bad hardware. Step 5: Then clean the computer of dust, clean the memory, graphics and other equipment finger, re-install the memory and other devices, then re-install the operating system, if
