how to spot a dodgy power supply? or something more.

Hello all,
i have recently built up a pc from the ground up and it occasionally acts up where it hangs for a moment when trying to do anything (ie open a web browser or look in some folders)
and when its really bad it freezes completely requiring a hard boot.

ive asked the techs at the company i purchased my parts from, and they think its the power supply, in the sense that the pins that connect to the mother board are broken.

What gets me though is that if the pc is acting up i can play a game that runs off the graphics card perfectly as if nothing is wrong but if i change windows or shut down the game completely it'll go right back to trouble.
if it acts up and i play a game that does not use the graphics card like binding of isaac or a facebook game, then it crawls and hangs quite abit.

The graphics card runs off of 2 extra cables from the power supply to power it up, also if it was component wouldnt the games be acting up as well?

ive done tests on all the components, 95 for the processor, memtest for the ram, speedtest for the hard drive with all passes. i have had a bad driver for something called VIA HD audio, which i promptly removed despite the fact i think my mobo has the chipsets (during idle the software will rev up to 15% on 3 cores on the i7)
of course there is no malware or virus's on it.

Your rig is well done and the psu is more than enough for what you are doing.

Download and install hardware monitor (freebie). Start hardware monitor and just let the system idle - note the voltages and temps of the various parts. Then run prime 95 and let hardware monitor run in the background (using the logging mode on hardware monitor) for about 5 minutes. Shut off prime 95 and compare your temps and voltages to the idle mode.

Did you install the most current motherboard drivers when you built the rig?

Post the results for both and let's see if we can find any issues.

I'm concerned about your core temps. Even at idle, you appear to be reaching 70* and under stress you are getting in the 90's. Your core voltage looks fine, but those are pretty high temps for just hanging around. Ivies do run hot, and sometimes the stock cooler just can't hack it.

Positive air pressure (more intake than exhaust) and good air flow in the case can also be a problem, especially with a 560 which runs hot.

What case are you using and how many fans (size, location, intake or exhaust). Are both the cpu cooler and gpu fans running quietly?

As an FYI, bumping is frowned upon.

alright i wont bump again, thanks for the heads up!

I'm running a pretty standard HP case that has a fan for the back adjacent to the processor fan, im not sure if its an in or out.
i am also running the fan/heat synch that was provided with the processor. which is a intake

if heat is a factor shouldn't the fan speeds increase? i find that rather odd.(found that one out the hard way when didnt sit the fan properly on the processor once whoops!) also is it possible that because of the heat maybe the ram could be affected by it as well since those have built in heat syncs?

recommend anything that could take that sort of heat? or am i going to have to upgrade the case?
 
Store bought pc's (HP, Dell etc) use very cheap cases and airflow is kind of an afterthought with them.

If you want to swap cases, look at the CoolerMaster Haf 912 - inexpensive, comes with to high flow 120mm fans and is a great value. If you got that, you could leave the stock fans alone and move the fan from the old case into the 912 as an additional intake (put it either in front or on top). The 120mm in the rear will be all you need for exhaust.

If you still have issues, it might be time to think about an aftermarket cooler such as a Hyper 212 EVO or Xigmatek GAIA.

Hey dude! just thought i should update on the progress, so i ordered the items in question and banged it into the machine, temps are brilliant and its so quiet, however the computer is still acting up and even acting worse than before, out of desperation i started to order parts and swapping them in to see if they worked and then got a refund if it didnt fix the problem, long story short it would appear my graphics card was the problem this whole time. only being a few years old at most it was dieing somehow, still baffles me to no end because i could play games so well on it!!!!
