I have struggled for 48 Hours trying to troubleshoot why al of a sudden my high performance ACER 9810–6393 20? notebook operates slow. THis problem only seems to be corrected by reinstalling the operating system and all applications. Within 2 weeks the problem reoccurs. Last time it reoccurred it was powered down by a low battery. System restore to an earlier date does not fucnction. I have disabled everything at startup with minor improvement. Safe mode works slow as well. I run perfomance test and overall score is 80 when it should be about 600. THis computer is required for my home business to run high perforance Data acquisition systems. When it works it’s awasome. When it goes bad it’s ussually in from of prospective buyers in a board room. I loose big time. I cannot keep reinstalling the operating system. I have run Norton System works, WIn check and Optimizer to no availe. It just tokk 12 Hrs to Defrag c:(100GIG). I have run ChkDSK, Defrag and my Taskmanager processes! Reads close to 0% for all TSR’s. Norton reports that I have a PEntium III whe it should be a Intel CORE 2 Duo T7200 with 2 GIG RAM. It operates like a Pentium III. IS it possible the software told the hardware to behave like a Pentium III? BOth ACER and Tigerdirect would not spend more than 5 minutes with me even though I was ultra polite. THey say my only solution is to keep reinstalling the operating system. no Exchanges and repairs or exchanges will be done by them for slow operation. Dell would have spent the time. Tough one. Help Leo PS I’d watch your show more often if I can get off this computer.
