Is my psu causing instability?

post #1 of 5
Thread Starter 
I have a CORSAIR CX750 psu. My problem is that when i boot up my system my rig often freezes at almost exactly the same position when just enetring the windows desktop. I have heard and read that my psu isnt to great psu. If you take a look at my rig and its components, do you guys think it may be my psu that cant handle the rest of my rig? And when measuring the volt at the 12v rail with aida64 it shows up at like 10.5-11volts instead of 12. How much impact will that droop in the 12v rail do? And how do you know if the psu is causing problems, are there any special symptoms for a psu thjat cant handle a rig? I know like when its a memory problem you get bsod´s, and when i clocked my gpu´s to high there will be flickering and stuff, and when to little volt to the cpu it causes reboots.

I know that the fx8350 cpu likes volts and i think the gtx660´s sli probably wants much volt when boosting at full speed as well. Is there anyway i can check my psu if that is the problem except measuring the rails with a multimeter? I know for a fact that it doesnt put out 12v or over that, and i know that the cx750w psu is crappy.

Thanks in advance!

Sounds more like a HDD or SSD thats dying

The CX is a downgraded TX as far as i know (could be wrong)

So its not as bad as the CX430M/CX500M/600M

Its still not the best PSU in the world

Your PSU should be able to handle your rig just fine.

I've had a similar situation, and it was my HDD. So I'd say the same as well.

I second that, it is your hard drive thats failing to loads the windows. Try the new harddrive and install OS on it.. u'll be fine again. Or take out the old HDD and format it with ur laptop or somehting.. then back in case and do fresh install. IF it fails then its ur HDD for sure that is died. smile.gif Happen to me in the past. thumb.gif
