Constant Explorer Errors

lemarsh · 15-07-2005, 18:33

Have recently started getting the following error : The Instruction at "Ox02c3321f" referenced memory at "0x00000000". The memory could not be "written".

This is always using explorer. 1st appeared when accessing my external USB hard drive (which has been working fine for months) and now has moved onto 'My Documents'. It is really restricting what I can do, and I cannot transfer anything out of the folder.

I have not loaded anything new recently (hardware or software), and the only Google notes I could find suggested deleting all .XLB files - but according to Search, I have none.

Any suggestions greatly appreciated.

When you get these errors, sometimes (in win XP) a pop up will enable you to send a report to Microsoft. That in turn can show up related knowledgebase questions that could give suggestions.

How hot is your PC getting? In this weather it might just be a bit of a strain on something. Check the cooling fans aren't clogged with dust.

Is the memory itself properly seated into the motherboard.

Of course you've got current antivirus, scanned for spyware and all the usuals.

You have checked your RAM haven't you?

RAM - how do I check RAM? Physically or 'PC' checking?

It could be nothing is running and it still happens.

There is no pop-up advising MS - it is either OK to terminate, or CAncel to debug, which then just freezes the pc up.

PC is not over hot, and occurs as soon as it is turned on.

Anti-Virus (AVG) & Spy Ware (MS & Adaware) both run OK

My mate had a similar problem that was caused by a dodgy beta Xvid codec.... Have you recently installed any video codecs??

I know it may not seem related to what you are doing when the fault occurs but as folders are opened windows tends to try and anticipate what you will do next and reads the first few frames of video files in the folder/drive (or a folder above or below) you have opened in case it needs to show a thumbnail or details.

not aware of downloading any new codec, unless Premier Pro has done it.

However, it is, at present, only happening in folders that have videos in it.

How do I check or correct codecs?

Right click 'My Computer'> Properties> Hardware> Device manager> Expand 'Sound, video and game controllers'> Double click 'Video Codecs'> Click on the Properties tab.

I'd check the properties to see if opening the properties crashes explorer. If it does then you know the one that's the problem. You could then remove it and download a dif version.

If opening the properties does not reveal the problem codec I suppose you could remove the ones you can easily replace from the net like DivX or Xvid etc. Just don't remove anything you can't replace....

you can replace all the default ones just by reinstalling media player 10 surely

Software checking will do for now

I'm sure it would help if the problem is with a standard codec........ Or reinstalling Premier Pro may help.

It's normally Xvid or DivX that cause the problem...

i said that in answer to the op deleting codecs he should not have done

Run chkdsk /f
Run virus scan
Run Windows Update
Buy new computer

Thanks for all your comments & suggestions.

Before trying too many things, I decided to see if a Restore worked, and it has (has brought a few other problems though, but I can manage them away later),

explorer now works great (well, as good as Microsoft Explorer can work anyway).

By the way paul, where did you get that Avtar. It's great! (well I like it)
