ok weird one after the MSI CR52-M 3.xx Firmware update, my work PC became painfully slow. Opening teh Start menu takes ages, and apps freeze for seconds at a time. Task Manager shows this:

Disk 0 (C:) Active time 100%
Not responding
the hard drive sits at 100% active time, with barely any read or write speed. response times are huge. before the update everything was snappy. im wondering whether teh storage driver is teh issue or whether my drive is dying at the worst possible time. what am i doing wrong??
