Apologies. You understand the despair of having a laptop problem and having no idea how to fix it. I've gone solo before, but this is above my head. But don't insult my lack of intelligence too much; I wouldn't stumble across this thread unless I was here for the exact reason everybody else is - Latency. LatencyMON has shown me that hal.dll, iaStor.sys and USBport.sys have either IRS and/or DPC's on a different planet to everything else. Anyway yes most of what you said is true. I installed the Tools Kit, but now, what, the rest is too vague for me to follow. Do you mean the C:\Temp file that is found in C\Windows\Temp? How do I open the Command Prompt in that?
