I have a Toshiba Satellite A205-S4587, 1gb RAM, dual core processor laptop. At times, mostly when starting up or waking it up after hours of sleep, the hard drive light is constant and I can hear it working but I'm unable to do anything and I am not running anything yet. I went into Task Manager and the CPU use was low but Memory usage was 90%. When I've just booted and nothing is running but Task Manager, memory usage is about 50-60%. With Chrome open it is 79-90%. I can't see that much is going on when looking at running processes. Do I just need more memory?
