Recently one of my computers keeps randomly rebooting without any sign of error. I have already removed the default reboot on error in XP so that i could try and see what happened but it still reboots leaving me to believe its not an OS problem. I also already checked all event viewers for apps and system and there are no reported errors. Current setup:

Gigabyte S2H 690g board
OCZ plat 2x1gb (default timings)
AMD 6000+ (default clock)
Seasonic 600w psu

The computer will reboot as soon as i click on the logon icon to get back into windows. I have reason to believe it is the psu since it is a few years old but this seems hard to trouble shoot. I am going to check the set voltage for the memory in the bios along with setting to fail-safe default settings and going to run OCCT tonight for a few hours to check cpu stability. I will probably also run Memtest on the memory this weekend to check for errors there as well.

Anyone have any other suggestions that i can look into????
 
OS corruption would be my first guess, seen XP do that before, normally a reload of the OS or a clean start will fix it. Possibly try safe mode and see if it will log in that way, if it does then run both options for scandisc and then defrag, then restart it and see if that fixed it, if not then choices 1 and 2 (format and install OS, or re-install over the top).
 
looking around i think my DDR2 voltage on the Gigabyte board is defaulted to 1.8v (at least that is what is says under PC Health) so i went ahead and adjusted the voltage under the advanced settings to +0.3. My OCZ is rated for 1.8v so that was probably the problem. we will see if i get more random reboots now.

Can anyone confirm this with Gigabyte boards about the default memory voltage?
 
hard random restarts should always ring a bell in your head saying "voltage/oc instability!"

did you check your system with memory/cpu tests in prime?
 
Going to be running OCCT today for stability test with new voltage setting, I will with my results tonight after a few hours of testing.
 
Okay so i need a little advice from someone who may have had similar experiences. After running for several days without any problems my other computer started to restart again. I pulled off the side and the northbridge seemed hot to the touch so i left the side off to see if that would alleviate the problem thinking i may be having a overheating issue. shortly after i get another restart....this time when i tried to plug something in to a USB port on the front of my case. After the computer restarted i tried to plug something in again and had the same results as before, an immediate restart with no record of an error. I am thinking a grounding issue but this just seems odd since the computer was just fine for months before this started happening. Does this seem like a possible power supply issue or my board??? I have the S3H Gigabyte 690g board. I have also considered getting a good Top-down cooler to help with the cooling around the cpu if that seems like it could be the cause.

Come on, i know someone here has to of had this problem :D


***tried to power on the computer after being powered off all night and when loading up in the desktop it restarted again:mad:
 
well i am continuing to have this strange issue and it is not consistent which makes it hard to determine what it is. As soon as a portable USB device touched my front USB ports the whole machine rebooted. Later in the day I tried to plug something in again and the problem did not happen again. Either my voltage lines are having issues, i have a grounding problem, or my board is starting to have issues. Still looking for someone who has experienced a similar problem to help out. any suggestions are welcomed
 
Did you ever run Memtest? If so, for how long?
 
yeah i ran 5 full loops of Memtest through all of the tests. I will run it for longer i guess and see the results.
