well, i had 2 system crashes (the mouse wouldnt move anymore, so had to hit the reset button) so I decided to instal asus pc probe II
and it indicated me that the 3.3v rail is at 2.95v (constatnt)
wich cant be good.

tough, according to the same program, my cpu temperature is 5*C, wich seems a bit odd too. (all other things seem normal tough)

Vcore is at 2.35V
+3.3 is at 2.95V
+5 is at 4.92V
+12 is at 12.02V
CPU is at 5*C
MB is at 30*C
SPU fan is at 2319rpm (stock cooler)
Chassis2 fan is at 1126rpm
shassis3 fan is at 1060rpm (those would be the 2 side fans plugged onto the motherboard)

either way, can anyone tell me where i can measure weither this voltage reading is correct, and what can I do about it?

edit:
Ok, rebooted and checked the hardware monitor in the bios. that said the 3.3 Volt rail is at 3.33V and the cpu temp idle at 34*C (seems a bit high, no?)

With the PC in your sig? 34C should be normal. With G0 stepping might be an bit cooler.

So, what is your question?
 
Do you have a multimeter? You can measure the 3.3V rail from a number of places, although it's a little more difficult on a unit like the Corsair 620W since the cables aren't colour coded.

You can either take the reading from:
  • The back of the 24pin ATX main connection (google a wiring diagram to see which hole to use), or
  • The modular interface coming from the PSU, or the back of any cable coming from it. The lowest pin should be the 3.3V rails (where you'd connect the positive terminal of your multimeter), the second lowest the 5V rail, the next two (square connectors) are ground, where you'll connect the negative terminal of your multimeter, and the top one the +12V.
 
so, going from top to bottom, it should be +12v, grnd, grnd, 5v, 3.3v? (the modular cable connectors that is)

edit: Ok, measured where you said, 12V rail is at 12.04V, the 5V rail is at 5.1V and the 3.3V rail is at 3.41V, so it actually seems ok.

now I have to go and search what actually caused the system lockups then. can anyone tell me how a intel processor responds when it gets too hot? (does the pc reboot, or how does it behave?)

I'm hoping that's 1.35V.

34C at idle sounds fine unless the room is cold. A Q6600's TDP is either 95W or 105W depedning on if the PCG is 05A or 05B.

An overheating Intel chip will do different things depending on what's active. Usually you will have throttling first. That wont lock the system up but it will get very slow. If the throttling function is disabled or there's a really big cooling problem the power will be removed from the processor. It will go right off, it wont reboot.
 
well, what my pc did was, the screen froze, the sound (music from winamp in the background) turned into a constant buzz (relativelt high pitched) and I couldnt do anything (not even the cursor on ym screen was moving)

as for the 2.35Volt, thats what pcprobe told me.. but I dont trust that at all :P
 
The sound was probably whatever was sitting in the buffer, I used to get sound loops and system lockups like that a lot when older games crashed. Still do very rarely. What were you doing at the time?
 
my pc was running internet explorer, WoW and winamp at that time. (the pc was on for quite a wile already tough.

I just enabled Q-fan control in the bios btw (I assumed it increases the fan's speed when the cpu gets hotter)
 
It's supposed to slow the fan down when it doesn't need to run at full speed. If Q-fan is the only thing you changed then change it back and see if it still happens
 
alrighty, think i found the problem. after rebooting the pc, pc-probe was indicating the right values (it seems) and when playing WoW the cpu temp rised to 52*C (right after I alt tabbed out of WoW) is this the issue you think, or..?

i noticed, that is with ventrilo and WoW running (thats 1 core 100% loaded, 1 at 40% and another core at 20%)
but when I run winamp too, it overheats, or crashes (not sure wich one yet), but without winamp it seems fine

Running winamp shouldn't cause overheating. Does the new winamp versions use more CPU power than winamp 2.xx? I haven't updated winamp.

I'm wondering if its some kind of sound driver conflict. Can you run any 2 of those programs (winamp/wow, winamp/vent, vent/wow) OK together?
