High DPC on a brand new PC?

[pote2639]

Hi
So I just got my new PC 4 days ago, everything seems find except one thing, the random freeze. I ever experience this problem on my old PC too, and suspecting it's about DPC latency issue.. again.
I tried to update every drivers as possible, like ethernet, GPU, USB controller, audio etc. and even re-flashed the BIOS. still..
Anyone have any idea what and why this thing still haunting me. and should I return my motherboard (or any parts that causing it) since I still got 7 days return policy until saturday?
Avg. latency: http://i.imgur.com/5CL9NJA.png (its randomly spike though, so I can't capture when there's was a lag)
My PC:
CPU - i7 6700
RAM - G.Skill 8GB DDR4 dual @ 2133MHz
Mobo - Gigabyte GA-H110M-DS2 DDR4
GPU - Zotac GTX 750 Ti
PSU - Seasonic S12 620W


Thanks in advance. and apologize for my english as I'm not native speaker.

Hi pote2639


Actually, the latencies in your screen-shot don't look that bad. The problem is that Latency Checker 1.4.0 doesn't produce reliable readings (it hasn't been updated since Windows 7). The Performance Monitor built into Windows 10 can produce a more accurate glimpse into the DPC situation for your computer.

Since the computer is so new, though, I think you'd be best off taking advantage of the warranty period, and have the manufacturer's techs take a look at it. You shouldn't have to spend hours and hours troubleshooting a brand new computer - it should work as advertised right away. And there are always some models that have "known issues" ... that your manufacturer knows about, and can repair/replace quickly.

Best of luck

Unfortunately, I convince them to change it but they said they don't found any problem and they seems doesn't understand what DPC is. and its the last day of 7 days returning. ah well, atleast I got warranty to covers for and it happening more rare than my old PC did so I'll keep it until I faces with those problem again. thanks again!

Hi again

If the system continues to freeze up, let us know. It sounds to me like the shop you bought if from (with the very small 7 day window for returns) couldn't have looked very closely for trouble. They should have seen evidence of the system non-responsiveness in the EventViewer logs.

There are things to look for and try: they are a bit time-consuming. Why not test your system out, doing all the things that you bought it for: push it to run your favorite programs and see if it runs OK or not. If it isn't running OK - then you'll have to figure whether to try the manufacturer warranty, or a self-repair. If it's hardware that is at fault, then you'll likely want to take advantage of the manufacturer warranty (they are usually good for at least a year).

Good luck!
