Spontaneous rebooting

By moorty ·
My pentium [166mhz 80mb ram and 2gb harddrive with WindowsME] with windowsMe is about 5 years old. Recently it has been for no apparent reason spontaneously rebooting itself. The display settings are at 16 bits [sometimes I changed it to 256 colors with no improvement] and 800X600, and moved the advanced performance scale all the way down. I also have reset the power management by removing hard disk turning off [it just has monitor turn off every 15 minutes or so]. And I have disabled the power savings thing in the Bios. But nothing seems to help. Is there a solution to the problem or is the computer [power supply, battery etc.] dying?

It sounds like a power supply problem. I've seen things like that happen with my old comtpuers and it most of the time was the power supply and or heat problem.

I've also had this happen on older machines and usually the cause is heat buildup. If you haven't opened the case lately, take a look inside to make sure the components do not have a layer of dust on them. If they do, use "air in can" to remove it. Also check any air vents on the case to make sure they are free and clear. Although the rebooting is usually spontaneous, you usually have a good idea of how long the unit will run before it reboots. If you want a cheap test for this theory, take the case off the unit, and run for a while without the case. You might even place a small fan close to the unit to ensure you have good air circulation.

If heat buildup looks like it's causing the problem, take a look at your CPU fan. Ensure that fan turns freely and is working properly (these will go out occasionally). If the CPU heatsink has fins, make sure you don't have a layer of dust in the heatsink. Last but not least, take a look at your power supply. Most power supplies also act as a case fan. Make sure that the vents are not obstructed, and that the fan is working properly.

While you've got the case open, gently press down on any chips that are not soldered in place. Sometimes the chips work up, and the additional heat in the unit causes them to temporarily lose connection.

Hope this helps.

Another possible consideration is your power strip/surge suppressor. I have seen these start to give out and create problems similar to yours.

Replase the power supply, the 5 volts is probably dropping out. They are cheap enough. You might even scavenge one from another PC. Make sure you get a large enough wattage, 250 watts and up.
