    Computer hangs periodically

    Hi,

    I have an HP PC with Windows 7 Home Premium and an AMD Phenom(tm) II X4 840T Processor 2.90 GHz processor with 6 GB of memory that started to hang periodically for 4 or 5 minutes once or twice a day. It doesn't appear to happen at any particular time or with any particular application.

    Once it it's finished doing whatever it's doing, it works fine for another extended period of time.

    When I look at Windows Task Manager, nothing is using a significant % of the CPUs.

    I've done a memory check. I've also messed with Resource Monitor and looked at "Analyze Wait Chain" and Event Monitor and nothing obvious shows up.

    I've done a number of virus checks with AVAST and a complete boot scan with nothing too much found and no improvement seen.

    I started to mess with ARO2012 and it found 2000+ issues, but thought better of letting it fix anything.

    Sooooo, my question is where to start to actually fix this?

    I could try a trial and error removal of programs from the startup menu, but that seems pretty random.

    Is there a program that might actually "point at" the cause of this hang?

    Is there a registry cleaner I should actually use?

    THANKS!!!!!!

    Do you see any disk activity while that happens? Are you able to open Resource Monitor when it happens?

    Don't throw random software like registry cleaners and tweakers at it, if there's no malware involved, I'd look at the drivers loaded next - even 'utilities' from motherboard makers can cause similar problems, as can virtual drive software.

    Run DriverView, set the View Menu to hide the Microsoft drivers and set the Columns so that only Driver name, Filetype, Description, Modified date, Filename and Service name are checked.

    Ignore any drivers that begin with Dump_ and copy the remaining details here, we'll try to check through them for known bad behaviour and older drivers that need updating.

    If Resource Monitor is already open, I can access it. If it's not open, most times I can't open new software.

    I don't think I ever saw any abnormal disk activity....what should I look for?

    THNX!!

    Just check if the disk activity is very high during that period. You can also try to see if CPU usage is high.

    I would follow satrow's advice as well.

    Will do!!

    CPU usage is never high when it slows to a crawl. I can't even check for email without the software timing out, but CPU will show 90+% free!!

    thnx

    Do you check that CPU usage value while viewing processes from all users?

    YES....it's never been above a couple % CPU usage during the hang period! System Idle Process is the only activity that's high.

    (I have some programs that are CPU hogs, but the PC still functions fine!

    When it hangs, nothing shows as using the CPU but everything slows to a crawl or is simply "not responding." When it "wakes up," everything snaps back to perfect!!!!)

    Ok, a quick scan through and I see Rapport, uninstall it, I've seen similar problems and BSOD's caused by it. It's also pretty recent judging by the driver dates, does that tie into the start of this problem?

    There's also some old, virtual drivers for USB, while I've not seen these cause problems, generally, virtual drivers are problematic for some users.

    Now that you can see the dates, try to update the drivers so that you have as few as possible from pre-2011, use the database here to help find a driver or makers site. EDIT: if it's a laptop, try to stick to the latest drivers from the makers for your model, many do not like using generic drivers.

    I also see a Winring0 driver running from a temp directory, do you know what that is?

    My Control Panel says Rapport was installed on 6/22/12, but I know I installed it at least 6 or 12 months ago, not in June!! (Maybe it updated itself????)

    Anyway, I did uninstall it.

    My guess is Winring0 is from a CPU temperature monitoring program I installed a few days ago when I read that CPU overheating can cause this problem.

    I'll start working on updating my drivers.

    THNX!!!

    PS: 5 minutes before I read your post, my PC slowed way down again......CPU never went above 9% and Resource Monitor didn't show any heavy use of the disk!!!???

    Hmmm. That's very weird. There should be an objective reason for an unresponsive PC. Among the list of processes, do you get a consent.exe?

    I know, it's been weird for a few months now!

    No process called consent.exe now, but I'll check during the next hang.

    Status update:

    Been trying to work on the problem and still get my required computer work done.

    1) Still hangs occasionally

    2) Never see a process called consent.exe during a hang period

    3) Rapport uninstalled (no change)

    4) CPU never registers about 10% use during hang (3-6 minute period), but shows very high use after PC wakes up, trying to catch up, then goes back down to background level

    5) Been updating drivers....very few show a newer version is available (I can repost if desired)

    6) Just updated whatever AMD drivers were available (included ATI Radeon HD2400 Series Display Adapter)

    7) Not sure it's significant, but I notice the computer goes to sleep normally when not used after rebooting, but tends to never go to sleep a day or 2 after reboot

    8) Not sure it's significant, but my wife has an HP laptop and that seems to periodically hang in a similar manner, but not at the same time my HP desktop hangs

    Any other suggestions?

    THANKS!!!!

    Two HPs doing the same thing? Looks very weird... Did you ever got to see apps started on boot, especially HP apps? You can maybe check with WhatInStartup, and even check if there is anything in common with your wife's computer.
