I came across a very strange issue. We have two laptops different models with 4GB RAM. The memory utilization for both these laptops run constantly at more than 90%. When you put these laptops in sleep mode and turn it back on, the memory utilization drops for sometime and then slowly regains it back to above 90%.
Task manager did not reveal any process for such hike in memory. Took out all programs from start-up without any success. Suspecting this could be a malware, I even ran Malwarebytes, Hijackthis, online eset scans, trend micro scan and still couldn't find any infection.
Can anyone suggest something that can be done to get the memory utilization down.
