Recently my computer's been acting a bit strange.. Every time I try to open a .avi file, a message pops up saying "explorer.exe has encountered a problem" and "(mediaplayername).exe has encountered a problem, and then all windows files/the media player closes. This problem also occurs when I open a folder or view a webpage that has a .avi file in it. I don't know what's the problem, but it only happens with .avi files... all other media files work alright.

I remember the last time everything was working well was before I tried playing a .mp4 movie file on the computer. The .mp4 file wouldn't play on any media player, so I decided to redownload those media players and codecs.

So far I've ran..
-Ad-Aware
-Advanced Spyware
-AVG Anti Spyware
-Spybot - Search & Destroy

Also, I tried System Restore (before the problem occured), but it was no use..
Any idea what the problem could be or how to fix it? Should I provide a HiJackThis Log?

Thanks. Much appreciated.

Hello, we are going to run System File Checker, to make sure all of your protected files are not corrupt. The scan will automatically replace any corrupt files that it finds.

Click Start
Select Run
At the prompt type sfc /scannow Please note that there is a single space between sfc and /scannow.

Typing this will start the program, and a box should appear telling you how much longer the process should take.

Sometimes the scan will prompt you for your Windows XP disc upon starting the scan. if this happens please make sure that you can view protected files:My Computer
Tools
Folder Options
View
"Uncheck" Hide protected operating system files.
Then rerun the scan. If this still asks you to put in your windows XP CD, and you do not have the CD (If you bought it preinstalled) post back for more tips, otherwise enter Windows CD.

Once the scan is complete:

Check your Windows Updates! After using the File Protection Service, you might need to reapply some updates.

Please reboot, and let me know if anything has changed.

Also, please rehide the protected files:My Computer
Tools
Folder Options
View
"Check" Hide protected operating system files.

Thanks for the response.

I ran System File Checker and went to reboot the computer, but the problem still persists. I tried to update Windows but for some strange reason, it says my Windows version isn't genuine.

Someone from another forum mentioned the use of VLC media player, which allows me to play the .avi files, but all Windows files still crash if I open it. Also, if I were to upload the .avi files online, open it from a burning tool or Windows Movie Maker (for example), the .avi files wouldn't open.

Are there other possible solutions?

Again, thanks for the help and much appreciated,

Jeff

What is the make and model of your computer?

Where did you purchase your computer from?

[Icecold07]

It is an HP Pavilion 061 computer, model D7222M-ABA A450Y, and I bought it from Best Buy several years ago.

Where did you get your operating system from? Has your computer ever been from the repair shop?

[Icecold07]

The operating system came built in, and no, it never had to go to a repair shop.
And just wondering, should I do a HiJack This scan?

I would contact HP with it saying your software is not genuine first.
