Roland, I installed mbmon, it looks like its a great application, but I have a question, I google it and I found no answers yet. With mbmon -r what values do you get? I figured out some but the rest I have no idea for what stands for.
# mbmon -r TEMP0 : 42.0 TEMP1 : 67.0 TEMP2 : 67.0 FAN0 : 0 FAN1 : 2410 FAN2 : 0 VC0 : +1.36 VC1 : +1.42 V33 : +3.39 V50P : +5.11 V12P : +12.04 V12N : +1.46 V50N : +2.29 ________________________________ From: Roland Smith <rsm...@xs4all.nl> To: Dánielisz László <laszlo_daniel...@yahoo.com> Cc: email@example.com Sent: Tue, November 17, 2009 8:42:18 PM Subject: Re: hdd voltage On Tue, Nov 17, 2009 at 09:43:04AM -0800, Dánielisz László wrote: > Hello, > > My computer get starts to reboot all the time I do a higher hdd use (like: > fsck, copying more GB of data).

Tools like mbmon can show you the different voltages that the power supply produces. But current isn't measured in the different circuits, AFAIK. If you see a drop in voltage before a reboot that would be a clear sign of trouble. Unfortunately the chips that do the monitoring sometimes only provide new values once every second. That is probably not fast enough to detect a swift voltage drop. There are devices (e.g. kill-a-watt) available that you can plug between the power outlet and the PC that show you the total power consumption. See e.g. http://forum.ncix.com/forums/index.php?mode=showthread&forum=116&threadid=1659654&pagenumber=1&msgcount=18&subpage=1 The abovementioned link shows a decent system using between 118 and 205 Watt. So I'd be surprised if your 450 Watt powersupply wasn't sufficient. (unless you have one of those graphics cards that is covered in fans and heatsinks and that you could still use to fry an egg on.) But I agree that it looks like a hardware problem. Unfortunately there are multiple possible causes. Check to see if all the cabling and cards are securely connected. Monitor the temperatures that the on-board sensors report. Remove dust from heatsinks and fans. Check the electrolytic capacitors on the motherboard. If the metal "lid" is bulging, it's busted.
