Computer automatic restart reason: hardware

1, box, power is not enough, dc output not pure, dynamic response sluggish. Users often don't pay attention to contractor or the installed power, USES the cheaper price of power supply gateway m6012 laptop cpu fan, so is the biggest cause the system to be automatic restart one of the suspects.
(1) the power output power shortage, when running large 3 D games CPU gateway m505b2 laptop cpu fan resources occupied large software, the CPU need high power supply, power is not enough and overload cause power protection, stop output. The power to stop the output, load reduced, at this time the power supply start again. Due to protect/recovery time is very short, so to our performance is host to be automatic restart.
(2) the power dc output is pure, digital circuit requirements pure dc power supply, when the power supply in the dc output harmonic content is too big, will cause the digital circuit to work the error, and the performance is a regular crash or restart.
(3) the CPU gateway m505 laptop cpu fan load is dynamic, and to the requirements of the current is dynamic, and requires the dynamic response speed quickly. Some of the poor quality power dynamic response time is long, will also lead to frequent crash or restart.
(4) update equipment (high-end graphics/big hard disk/video card), increase equipment (burners/hard disk), power beyond the original power rating of the output power will lead to frequent crash or restart. Solution: now in high quality high power computer power.
2, memory, thermal stability, the undesirable chip damage or set wrong memory problems cause the system to restart the system of the chance to restart the relatively large.
(1) memory thermal stability is bad, the boot can work normally, when memory temperature to a certain temperature, it can not work normally, which lead to crash or restart.
(2) the memory chip slightly damaged, the boot can through the gateway m500b laptop cpu fan self-check, also can enter the system, when running a few large software throughput will restart or crash. Solution: replace memory.
(3) memory CAS value is set to is too small can also lead to memory is not stable, cause system reboot. General had better use BIOS default setting, don't be changes.
3, CPU temperature is too high or cache damage
(1) high CPU temperature often causes protective reboot. The cause of the high temperature basic is due to a chassis, CPU heat is bad, the CPU heat dissipation bad reasons are: the material of radiator thermal conductivity low, radiator and CPU interface between the foreign bodies (more for quality assurance 1), fan speed is low, fan and radiator dust too much, and so on. And P2, P3 motherboard CPU temperature below the probe damaged or P4 within the CPU temperature detection circuit is damaged,gateway m465-e laptop cpu fan the BIOS on the mainboard BUG in a special conditions temperature measuring forbids, set up the CPU CMOS low temperature and so on protection can also cause protective restart.
(2) the CPU of an internal level 2 cache, damage is CPU common fault. The extent of damage of the light, or can start, into the system, when running a few large software throughput (media player, game, plane 3 D graphics) will restart or crash.
The solution: the shield in CMOS level 2 cache (L2) or level cache (L1), or replace CPU ruled out.
4, AGP graphics, PCI CARDS (nic, cat) cause reboot
(1) the external card work not standard or poor quality, cause AGP/PCI bus signal RESET error action led to restart the system.
(2) and video CARDS, network adapter loose cause the system of the restart case.
5, parallel, serial ports, USB interface access is a failure or not compatible external equipment reboot
(1) with the fault or not compatible, such as printer parallel port damage gateway m460 laptop cpu fan, a foot of short circuit, USB equipment damage of short circuit, the pins definition, the signal level not compatible with, and so on.
(2) a hot swap external equipment, dithering is too large, cause signal or power instant short circuit.
6, cd-rom internal circuit or chip damage
Cd-rom damage, most of the performance is not read dish/hour plate. Also have for internal circuit or chip in to host the working process of the damage in the restart suddenly. The cd-rom itself bad design FireWare Bug. Also in reading the disk will be caused to restart.
7, box, the front panel RESET switch case the front panel is actually a RESET button to often open switch, on the main board of the RESET signal is + 5 V level signal, connected to RESET the switch. When the moment of closing switches, + 5 V level ground conductivity, the signal level reduced to 0 V, triggering system RESET to restart,gateway m360 laptop cpu fan switch back to RESET to often open position, this time the RESET signal back to the + 5 V level. If the RESET button damage, switch is always in the closed position, RESET signal has been is 0 V, system cannot add electric self-check. When RESET switch elastic abate, button press not easy pop-up, can appear a slight vibration switch is easy to closure. Leading to restart the system restoration.
Solution: replace RESET switch. Also the switch lead organic RESET circuit, leading to host reboot.
8, mainboard failure
The mainboard lead to reboot examples are rare.gateway lt3114u laptop cpu fan General is RESET and related circuit has fault; Socket, slots have empty welding, contact undesirable; Individual chip, capacitance elements such as damage.
