Hi, I keep getting these awful error messages: "The instruction at referenced memory at...". They vary; the current one says Microsoft Windows Search Protocol Host: wermgr.exe Instruction at 0xfc5ed0e referenced memory at 0x00000000. To spice things up, I get the occasional BSOD with the error message "IRQL equals or less." I uninstalled ATI catalyst manager. I ran memtest and got a pass with no errors. My system: Windows 7 pro / 64bit. 12 GB ram, Intel I7 920. Antivirus: Kaspersky, latest edition, trial version. Any ideas? Thanks!
