PC Random Reboots Hardware
I have a PC that randomly reboots. I convinced it is a harware fault
because sometimes it will reboot even before it begins loadng the op sys, i.e after one or two seconds of switching on. Besides I have tried reinstalling the op sys and this didnt fix the prob. When the machine does boot it will run for anything from five minutes to five hours but will suddenly just reboot. CPU fan replaced, CPU temp looks fine, its a duron 1400 and running at 95C. No additional PCI cards fitted. Usually reboots while acessing CDROM. Which is the most likely culprit? Mobo, CPU, PSU, Ram? Any Ideas? |

Windows XP?
There's a feature that will restart system when an error (no matter how critical or not) occurs. Seek it out and disable it if you have XP. (Blue) wrote: I have a PC that randomly reboots.

Well, I'd suspect either the motherboard or PS causing the reboots being
that it's doing it before the OS gets loaded. It sounds somewhat like the problem I posted about with a PCchips Mobo. Or It could possibly be memory errors, try downloading the free memory tester memtest86, I don't have the link handy, just google for It. However, I'd certainly recommend disabling the auto restart feature of XP. (If you have XP) To do so: right click on the "My Computer" icon on the desktop, click the "Advanced" tab, click the Startup and Recovery "settings" button, then look for the checkbox for "Automatically Restart" uncheck it, click ok and restart if prompted. I'm sure other people with think of some other things to check for. Hope this helps, Troy "Justice Gustine" wrote in message ... Windows XP?

Thanks for the tip but it often reboots before the op sys is even
started so I am pretty sure this is a hardware problem. Anyone else had this? There's a feature that will restart system when an error (no matter how critical or not) occurs.

Yes, it is F, well spotted
If your temperature really is 95C, not 95F, you have a problem. Normal operating temperatures for an AMD processor are in 40C to 60C range, with problems guaranteed to happen with temps much higher. JT |

It could be your CD-Rom, if you have the CD-Rom in the BIOS as a bootable
device, and have a non-bootable CD in the CD-Rom drive, it will cause this type of problem. Either change the BIOS setting and disable boot for CD-Rom or make sure that you don't have a CD in the CD drive when booting. Dashi "Blue" wrote in message om... I have a PC that randomly reboots.
