Windows 7 64-bit hanging randomly for 15-30 seconds

I changed it to a small memory dump, and when it hung again, it created a dump file of 839 megs. I'm going to have to try to catch it when it hangs in a different program.

Does the HD light come on and stay lit solid during these events by any chance?

Yes, the HD light comes on a stays lit during these hangs. I've done tests on the drives with SeaTools, and everything checks out. Any other suggestions to test the drives?

Hi,

I'd go for a HW problem...

try to download ProccessExplorer (formally sysinternals)
http://download.sysinternals.com/Fil...ssExplorer.zip

look to see whether when the system hangs the part of " Hardware Interrupts) consumes a big chunk of your system resource Memory ar probably better - the cpu.

If it does, try some HW diag tools:
HDTune - http://www.hdtune.com/files/hdtunepro_401_trial.exe
MemTest - http://hcidesign.com/memtest/MemTest.zip
System Integrity Checker - Start > Run > CMD >Right Click and Run as administrator > SFC/ SCANNOW
(thanks to Captain)

Hope that helps...

I'll take a look at that.

I tried the system integrity checker, and it did not find any integrity violations.

If the HD come on it is likely a storage driver issue. If you are using an SSD then there is a specific problem that causes this exact thing and it is called "Native Command Quing" a feature put into drivers snd rotating Hard Drives so theycould queue up may read or write commands and execute them in the order that was best for the current position of the heads.

This is not neded so much for SSD, though is available but I found that on my SSD it would frequently hang the system like this.

First I would try updating the intel or nvidia storage drivers for your mother board. If that doesn't work, turn off NCQ:

Find the SATA entry in the hardware manager for the drive in question and then fin the setting in one of the tabs to turn off Native Command Queing (NCQ).

The one side effect of this that I've seen is that the Windows Experince Index will not run. It bails out at testing the HD :/
