Windows 7: Motherboard temperature?

a poor PSU will allow voltages under load to drop and any of your devices like CPU and Ram will begin to generate errors due to lack of voltage.

I would keep that screenshot and ask them for another decent power supply not just another swop out cheap and cheerful ?

If you get the opportunity maybe ask them what make and model PSU they have fitted.
Thanks for the info mate!
I can hear my fan running all the time at 100% even if pc is idle, and it is kinda annoying.. Is there a way to set it to lower speed, or to set it so it could adjust itself automatically when higher RPM speed is needed? If there is a way to do so, please explain it to me, I've tried Speedfan but I guess I'm too stupid to configure it properly

If the +12V were that low, then his system wouldn't even function. It probably wouldn't even turn on.

These voltages are best measured with a physical meter connected directly to the cables instead of using software. Software is notorious for being inaccurate when it comes to PSU voltages.

I agree voltage monitors are notoriously inaccurate but they can be indicative and I have seen systems run with voltages dropping under stress to below 9v ish when PSU's are faulty.

measuring with a meter is the shops problem I reckon and he cant break the warranty by opening the box

re the fan you need to know if its a speed controlled version and then set it in the BIOS, at this stage that might be something else to ask the supplier about ..........

As measured with a meter, or with software?

Before I upgraded to Sandy Bridge, I had an E8400 in the Gigabyte EP45-UD3P. HWMonitor showed about 8V for my +12V, yet my system was working perfectly for everything I do with it. I had the same PSU that I have now (the original HX650). With my new parts for Sandy Bridge, I don't have a +12V measurement in HWMonitor. Everest is showing me 0.061V, and HWiNFO is showing 12.00V. ASUS AI Suite II is showing 12.00V too.

So, I guess I would recommend giving HWiNFO a try (it's free):

software so agreed inaccurate but as i stated before indicative and it did highlight a PSU fault.

to truly measure PSU output I do have a socket that links on to a motherboard plug but 9/10 I have found software for most probes that give an accurate enough reading by comparing outputs in windows to outputs in BIOS.

To the OP what are the voltage readings in BIOS ?

Maybe, but I had an ~8V reading for my +12V back when I had an E8400 in the Gigabyte EP45-UD3P. I had the same PSU then as I do now. The reason for the +12V reading back then was due to the BIOS reading I was getting. My current motherboard shows +12.00 in the BIOS, and so does HWiNFO and even ASUS AI Suite II, but I have no +12V reading at all in HWMonitor.

So I'm just saying, it could also be nothing.

Voltages readings in BIOS are ok, so for that +12 is around 11.5.. I think I have figured out what was the problem! My fans were stuck to 100% all the time, even when idle, so I have changed that in BIOS so now they run at 40%, but when game is on fans get up to 80% and temps are still fine according to HWmonitor! That stress test still says that PC running unstable, but all games and programs are running fine and without crashes so far!
Could have that 100% fan speed (and thus consuming unnecessary power) been the problem all along?

Does HWMonitor say 11.5V? Or does it still say about 8V?

Don't worry about that mine reads something like 11.71 I think it has a misreading when it come to accurate voltages

me and a few others came to that conclusion but temps are dead on
