Intel Pentium G3220 - idle total CPU usage averages over 20%?

post #1 of 6
Thread Starter 
Hi, all

I just built a basic computer for a friend whose needs are modest (web surfing, MS Office, etc) using a Haswell Pentium G3220. It runs Windows 7 Home Premium 64-bit with 8GB RAM.

Even when idle, according to HWiNFO64, the "Core #0 Usage" averages over 40% whilst "Total CPU Usage" averages over 20%. "Core #1 Usage" stays at 0%.

Can fellow forum members comment on whether this is normal for the Pentium G3220?

Thanks!

Under CPU in Resource Monitor, "System Interrupts" (Deferred Procedure Calls and Interrupt Service Routines) accounts for practically all "Average CPU" at over 20.00 (%).

Any ideas?

DPC Latency Checker shows that the machine's latency is fine.

What does ending the process do?

Using Process Explorer in Safe Mode, the System Interrupts hog disappears.
