I run a dell system Latitude D630 about 1 year old with XP. I run IE 8.1 and I have had this problem for some time. It now freezes 3-4 times per day and I have to power down and back up to do anything. I have tried Dell multiple times to no avail. Sometimes after it freezes I get a message: The instruction at "0x71a6b2fa" referenced memory at "0x00000008". The memory could not be read. Any thoughts on how to ix this? I have run malware and spyware checks.
