Spontaneous reboots :-(
Hello. As found in many posts below, I recently upgraded an Athlon XP2000+
on a MSI KT3 Ultra VIA KT333 chipset to the same board with a XP2500+, 512Mb Corsair PC3200 RAM, plus new heatsink. I have Win 98SE. I'd changed the FSB to 166, and RAM settings sorted, CAS 2.5, I thought it was all stable and OK. Memtest was fine, Windows processor load was 100% (using SETI) for three or four days running 24/7. The BIOS reported temp has never been above 39 degrees, with system temp about 33 degrees (side off case). Last night, playing a 2D game (Northland demo), with SETI running in the background as low priority, Windows rebooted with no errors or anything. (I have played the game like this before with no probs.) Then it did it again during Scandisk on the reboot. I had just got into the BIOS to check things and it did it again. I have dropped back down to FSB133, and changed the memory, too. I don't know if this will cure the problem. Why should it do this after four days of running fine? The m/b, CPU and memory should have no problems at this speed (FSB166). The PSU is 300W, it has a two disk RAID to supply plus a DVD-ROM drive. The graphics card is a nVidia GeForce 4 MX440. Please help. -- Susan |

Please help. You may have mentioned it in the past, but we've covered a lot of ground.... what make/model/etc power supply? Did you get the northbridge heatsink/fan issue resolved, are sure it's running cool enough? Does the BIOS or window hardware monitor report good voltage levels? Is it possible to check the power supply voltages with a voltage meter? Does it only become instable after running for a while, or can you duplicate this when the system has been off, cooled down, hasn't ran for very long? Are you or were you running with the case cover off? If you're now using a passive northbridge cooler, in some situations it can help to leave the cover on. Dave |

Please help. You may have mentioned it in the past, but we've covered a lot of ground.... what make/model/etc power supply? Qtec Model ADT300 300W It has a Pentium 4 sticker on it. Did you get the northbridge heatsink/fan issue resolved, are sure it's running cool enough? I added the oil and it seems to be fine. The heatsink is on the 'to do' list. HOw can I tell how cool it is? Unless it is reported as 'system temp' (which is about 33 deg) I can't see any other temperature given. Does the BIOS or window hardware monitor report good voltage levels? The Windows monitor says VCore 1.65 V, but it's not brilliant, I'll come back to you with the BIOS ones. Is it possible to check the power supply voltages with a voltage meter? No. Does it only become instable after running for a while, or can you duplicate this when the system has been off, cooled down, hasn't ran for very long? Are you or were you running with the case cover off? If you're now using a passive northbridge cooler, in some situations it can help to leave the cover on. It had been running for about 4 days, CPU load 100%, with the cover off. This because firstly I'm keeping an eye on the northbridge fan, although it seems fine so far. Also the RAID cables are the flat ribbon sort and they obstruct the air flow. I could close it up now I have the new heatsink/fan, I suppose. I turned it off last night, after changed the FSB to 133. It has been running OK so far this morning at 133. I don't want to risk my data too much. I have the new HDs, so I could attach one and clone the drive(s), but I don't want it to reboot right in the middle of it! -- Susan |

I've had this *occasionally* before. Is that indicative of anything? -- Susan |

I'll see watt (geddit?) I can find on the UK sites, Sparkle or Fortron, you say... Yes, a standard ATX has the following dimensions in millimeters: rear (side that screws to case) 150W x 86H Length (front to back of case) 140 Sparkle/Fortron are among the best values in the US, but over there... don't know. One drawback to the Sparkle/Forton 400W is no air intake on the underside. That is a useful feature and it's unfortunate that they don't have it. With your CPU socket so near the top of the board it might be even more beneficial to you as it would more directly remove heatsink exhaust instead of recirculating it through the 'sink fan again. Antec is another option, has the fan underneath. Dave |

It had been running for about 4 days, CPU load 100%, with the cover off. FWIW (and you may already know this), but running with the cover off tends to really screw up the airflow that your case attempts to create with its cooling fans. And running with CPU pegged tends to generate a lot of heat. It's possible your BIOS could've sensed an overtemp condition and triggered the reboot, or its possible the higher temps threw an exception or caused some sort of error that caused the OS to rebot. Is this Windows? If so, turn auto reboot on error off--that way you can see the BSOD to see what exactly happened if the OS triggered the reboot. In win2k this setting is he startsettingscontrolpanelsystemadvancedstartu pandrecover Uncheck AutomaticallyReboot Check write event to system log If write event to system log is already checked, perhaps the cause of your reboot is in your EventViewer log in the system log section. Event viewer can be found in win2k under: Startsettingscontrolpaneladministrativetoolsev entviewer Best Regards, -- Todd H. http://www.toddh.net/ |
