Exception EAccessViolation?

[Yochanan]

I keep getting this error from time to time and if it's related to a specific app I'm at a loss which one. Googling it didn't reveal any useful info. The only thing I could find was that perhaps some application is trying to access an area of memory that Windows is not allowing it to. I suppose it's possible my RAM could be going bad, I'll run a test later and see if that reveals anything.

Application Error

---------------------------

Exception EAccessViolation in module rtl120.bpl at 0000456F.

Access violation at address 5000456F in module 'rtl120.bpl'. Read of address 032A002A.

do you have ms visual 2008? also try process monitor on the offending app and see what it is accessing heavily.

[Yochanan]

No, I don't have MS Visual. Like I said, I don't know what the offending app is. Event Viewer does not log the error.

Is Auslogics disk defrag installed? Is it defragging in the background? Or running on / in startup ?That file may belong to this. Try reinstalling it. Is the latest version installed (3.1.0.65)?

an application coded with Delphi 2009 causes an Access Violation (null pointer access)

No, I have Tune-Up Utilities 2010 installed and had the auto defrag enabled as part of the 1-Click Maintenance. It's only supposed to run every 3 days when idle, but who knows. I've disabled it and went with PerfectDisk 2010 instead. I haven't had the error since, but it's only been maybe 12 hours. The error is pretty random, but never right at startup. It's usually after I've had the computer on for a day or two.

It was Tune-Up Utitlites. Event Viewer showed and entry after the latest error:

The description for Event ID 0 from source TuneUp.UtilitiesSvc cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

LoadTUProcessDriver(). StartDriver() succeeded!

I uninstalled it for now to see if the error reappears with it gone.

Sweet, good to hear the prob is fixed

[MagicAndre1981]

yeah, TuneUp is coded in Delphi.
