Hi there, I'll share system specs first before I detail my potential problem:
I7 2700k 4.5ghz 1.31v, cooled by coolermaster seidon 120v
Gigabyte Z68xp-UD4
8GB Corsair vengeance RAM
R9 290 cooled by corsair HG10 and Corsair H80
Corsair TX850M
Kington 60GB SSD
WD 1TB
If I've missed anything off just let me know.

Now for the advice part, I've been thinking lately that my PSU is failing, for this reason I keep getting strange burning smells in the room where my PC is located.
Coupled with this is the crazy +12V readings I'm getting in speccy and HWinfo idle it is normally 11.926 but I get drops to 11.141 and idle 11.926 degrades by doing nothing.

I can cause the massive drops by opening tabs in firefox and even something simple as just typing, accompanied by the drops is a drop in fan speed or a pump speed I'm not sure which though but the fluctuating noise can get annoying.

I've attached a pic for you to gander at and ignore the CPU temps for some reason the C states aren't kicking in so the CPU is stuck at 4.5ghz when it should only be the turbo speed.

To summarise would you say the motherboard is bad or is my power supply now confined to the scrap heap?

Cheers


Well done for checking you spelt the thread title correctly Ian, jeez louise.

Have you tried removing your OC and seeing if this helps at all as this will put less strain on the PSU, try this for a few days or weeks and see if this helps or resolves the issue.

I've already tried that unfortunatley.

Just to clarify also there is fan speed drop it's a fan I've got plugged in, in System 1.

Oh and there is no overclock on the GPU it's all stock.
 
does sound like the PSU at fault, does this happen when the PC is not in use and just sitting on the desktop or is it stable till you start using the PC?

I take it that you don't have a spare PSU to try at all or can borrow one from someone?

just had a read up and can see that the motherboard as a integrated GPU, take out the current GPU (290) and use the on board one as this should drop down the amount of power the system is using

All in all the system is stable no BSOD, or artifacting, or random shutdowns.

The only real issues I have had is the overclock that was stuck on before, which a reboot fixed, and the endless amount of time it takes to shutdown and for the WLAN device to connect.

Just tried Tropico 4 too to see if there was any issues and I got crazy stuttering which I've never had before with 36 hours logged anyway.
 
Ok small issue, it does have on board video but I don't have a HDMI cable or a DVI to HDMI adapter, I still can't narrow down what's causing these weird intermittent issues though seemingly the USB 3 ports aren't getting any power now as the WLAN module won't power on.
 
Dont rely on software for voltage readings, if you have a multimeter use this to check the voltages.

I know your right but I though it was very strange that the reading were all over the place.

I think the motherboard is bad in all honesty, random shutdowns, USB3 not working, all cores stuck on the same multiplier.

I'm going to order another motherboard just need to find a p67, z68 or z77 board that still works :/
