System has become unstable and CPU temp of 82 Degrees?

[projects14a]

Right, ive had a problem since building my new PC. After automatically going into "Sleep" mode, once woken it freezes, after 10-15 seconds it will allow me to move the mouse cursor and use the PC, but it then freezes again and so on. Nothing obvious in task manager is causing the problem and the only fix is to reboot. Unfortunately, most of the time it freezes during the shutting down stage, so ive had no alternative but to hold the power button.

To prevent this happening i told it never to go into sleep, as i've not had time to figure it out, but last night i put it into sleep, and when i woke this morning it was back on again It did the usual freezing thing and i noticed abit's UGURU icon flashing in the systray, apon opening i discovered the CPU temp was 82 degrees! I also noticed in task manager that UGURU was also using the CPU more than anything else and a fair amount of memory, which i thought was strange for a pretty small application.
I was able to check the core temps using CoreTemp and it told me they were all around 30-31 degree (which are my normal idle temps). I then shut it down, left it for 20 mins and booted it up, checked the temps and they were all back to normal, UGURU said the CPU was 16 degrees, as did Fan Speed (which i think is driven by UGURU anyway?) and core temps again around 30 degrees. But when i tried to open IE, it then froze again. After restarting it now seems to be ok again.

What is the difference between CPU and Core Temps? Cores are always around 28-32 but the CPU is always around 16-22.

My specs are as follows:

Abit IP35 Pro (Socket 775) PCI-Express DDR2 Motherboard
Tuniq Tower 120-LFB CPU Cooler (Socket 478/754/939/940/AM2/LGA775)

Nothing has been overclocked other than the graphics card using CCC, but it was doing this before i modified the settings and before i upgraded the latest version of its drivers and CCC.

Has anyone experienced anything like this before? Im getting alittle worried because of the CPU temp, especially as the fan speed was at 1920 rpm (the fastest it can spin). How can it get this hot when the load was under 20%?

Any suggestions would be greatly appreciated. I was hoping to start overclocking soon, but until im sure this isnt hardware related i dont really want to try my luck.

Thanks!

Core temp: temperature taken from a sensor built into the CPU itself. The most reliable way of taking temps.
CPU temp: temperature taken from a sensor somewhere near the CPU. Will be lower than core temp.
UGuru: probably lying.

Can you run Prime95 and watch your temps in CoreTemp? If you get any more 80c+ readings, it would most likely point to your heatsink not being fitted properly. If the temps stay lowish, that's not what's causing your problem.

My DFI board originally had a BIOS bug where after coming back from sleep the temperature would be reported completely wrong. It would then shutdown shortly after returning from sleep. Until they put out a BIOS fix, the solution was to turn off the "after 60 deg C, turn off" option in the BIOS.

Thanks, will look into both of these suggestions. Have had issues with uGuru from the start with vista 64bit, it never closes down properly and sometimes doesnt load properly on start up. Ive updated to the latest version, but no improvement. Anyone think i should just remove it an use other apps to monitor temps? I havent done that as im unsure whether it contains any of the mobo drivers in the package.

Right, just ran Prime95 for an hour and temps seemed ok, max reached was 44 degrees on cores 0 and 1, 2 always stayed 3-4 degrees less and 3 was 1 degree less. Average load temp was 41 degrees for cores 0 and 1. All tests passed successfully with no errors or warnings.
Will look into BIOS settings, but being a different mother board, may not be the same issue. Would it be worth upgrading the version of bios? Read somewhere it was best to leave them alone unless you had an issue.

yeah i would remove uguru if its having issues running in vista
coretemp would be the best option to monitor your temps
another option could be to use speedfan as well if it reads your mobo properly
as far as sleepmode is concerend i too have a similar issue with vista not coming out of sleep mode properly yet it seems to work properly when i boot into XP the only thing i can think of is a chipset driver not working properly.
Being i have an old Nforce 4 chipset i doubt there is going to be an updated set of drivers for my system however your mobo is a different kettle of fish

Have both SpeedFan and CoreTemp installed so can monitor temps with those, will probably disable uGuru from starting up in msconfig and see whether the issues reamains.
