iexplorer.exe application error: the instruction at "0x7c915d67" reference memory at "0x6126206f". The memory could not be "read"

I'm getting this error:

   iexplorer.exe application error: the instruction at "0x7c915d67" reference memory at "0x6126206f". The memory could not be "read"


I have winXP SP2 and I have two user accounts and the IE has errors in both users the error in the second user is different. The Error is:

   svchost.exe - Application error: the instruction at "0x7c7a76a3b" reference memory at "0x6126206f" could not be read.

but with this one it kicked me out to the login screen.  I Also tried to get on the net with firefox but says the application has an error and needs to close.  I am able to cheack my mail in outlook.  

For more info on this I just had my tech reinstall every thing do to my old HDD died.  So he did all the window updates.

Can anyone please help me???  Thank you.

Have you checked your memory for errors?  Try this freebie from Microsoft:

If you are experiencing problems while running Windows, you can use the diagnostic to determine whether the problems are caused by failing hardware, such as RAM or the memory system of your motherboard. Windows Memory Diagnostic is designed to be easy and fast. On most configurations, you can download the diagnostic, read the documentation, run the test and complete the first test pass in less than 30 minutes.

I'm guessing it's some type of spyware that's badly written.  spyware and malware generally 'look in' on what IE is doing so they can send the information to whoever made it.. these are generally poorly written and cause these types of problems.  I would try to see if you can run some type of spyware/malware scanner on your machine first if you can download one and then copy to that computer since you can't use IE or Firefox.. and then SP2 to see if it fixes it.. you might be able to boot into safe mode by pressing F8 before windows is starting up and select with network, this will probably disable the bad malware and let IE work correctly.. the malicious code remover is good to from microsoft.. http://www.microsoft.com/security/malwareremove/default.mspx#run if you can get IE to run in safe mode with network.. you can also download it using another machine and copy it to that one but if it can't access the IE internet access subsystem it probably won't run that way.. SP2 reinstall is a good hope, but probably won't fix it as it's going to see the spyware as software you installed and leave it in place, but worth a shot...

I've already check for spyware and adware and it is not that.

I'm reading the Windows Memory Diagnostic user guide so I can test the memory out.

but just in case its not the memory I'm still open for suggestions.

Take a look at the following web page,

http://aumha.org/win5/kbestop.htm

which is presented using frames.  Click on the error code (50) in the left pane of the page, which is a link to the following quotation:

Requested data was not in memory. An invalid system memory address was referenced. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems (e.g., incorrect SCSI termination or a flawed PCI card).

symevent is usually symantec-event or Norton anti-virus or internet security, also try uninstalling norton, reboot, reinstall, reboot and see if that will fix it.

could very well be that Norton is the one messing with your IE, as I previously said it's probably something that is trying to control what IE does (like spyware and malware) Norton (for good reasons) does this.

I've checked the system for falty Ram, hdd, system files, restalled the IE, unstalled the Symantic AV and install Kaspersky AV
Scan for Viruses and trojians, so far it looks like its fixed.  Thank you for your help.
