Instruction at 0x072b007a referenced memory at 0x00000000 The memory could not be read.
This error message is coming up on my computer at random times. Nothing specific (atleast from my non computer guru self) is triggering this. I have Windows XP Home Edition. Is there a fix?1 person needs an answerI do too

If the error is truly random, (i.e., you're not running the same program at the time the error occurs) start troubleshooting by:1. Test the RAM.2. If the RAM tests OK, then do clean-boot troubleshooting to find out what program/process is failing.Testing the RAM:You can test the memory yourself. I like Memtest86+ from www.memtest.org . Obviously, you have to get the program from a working machine. You will download the .iso to make a bootable cd. You want the pre-compiled bootable ISO (.zip). Unzip the file you download by double-clicking on it and drag the contents out. You will now have a file called memtest86+-4/00.iso (the version number may be different). You can delete the .zip file now. Put in a CD-R disc and start a third-party burning program such as Roxio, Nero, or the freeImgBurn (unless you have Windows 7 which can burn .isos natively). You will need to burn the file as an image, not as data. Refer to your burning program's Help if you don't know how to do this.Leave the CD-R in your optical drive and restart your computer. When you restart the computer you will see messages:1. Possibly a message that says something like "Press F12 for temporary boot menu". If you have this message, press that function key. Use your arrow key to select the CD/DVD drive and the computer will boot from the Memtest86+ CD you made.2. If you don't see a message about a boot menu you will need to go into the BIOS to change the boot order. This message will say something like "Press F2 to enter Setup". Press that function key and you will enter the BIOS. Find the section about boot and change the boot order to CD/DVD drive first, hard drive second. Save your changes and exit Setup. The computer will boot from the Memtest86+ CD you made.The test will run immediately. You can remove the CD while the test is running.You will need third-party burning software to do this Burn as an image, not as data. Then boot with the media you made (you may need to change the boot priority in your BIOS so that the optical drive is the first boot device). The test will run immediately. Let the test run for an hour or two - unless errors are seen immediately. If you get any errors, replace the RAM.Clean boot in Windows XP -http://support.microsoft.com/kb/310353Clean-boot advanced troubleshooting in Windows XP -http://support.microsoft.com/kb/316434MS-MVP - Elephant Boy Computers - Don't Panic!
