You can disable error reporting but thats not your problem, you need to get to the bottom of why IE is crashing
Heres how to disable error reporting
1.
Click on Start and then Control Panel.
2.
Click on the Performance and Maintenance link.
Note: If you're viewing the Classic View of Control Panel, double-click on the System icon and skip to Step 4.
3.
Under the or pick a Control Panel icon section, click on the System link.
4.
In the System Properties window, click on the Advanced tab.
5.
Near the bottom of the window, click on the Error Reporting button.
6.
In the Error Reporting window that appears, choose the Disable error reporting radio button and click the OK button.
Note: I would recommend leaving the But notify me when critical errors occur checkbox checked. You probably still want Windows XP to notify you about the error, just not Microsoft.
7.
Click the OK button on the System Properties window
8.
You can now close the Control Panel or Performance and Maintenance window.
Regarding IE crashing
try this
Start>run>cmd
Type sfc /scannow and hit enter
It will scan you system and check the system files are correct and intact, you may need the Operating System disc, as if files are corrupt or missing it will need your disc to pull them off.
Good Luck
