I recently brought a laptop ACER Aspire E5 - 551G that came with Linux so I clean installed Windows 7 Ultimate.
Now, the problem is that every time I start the computer the physical memory sky-jumps to about 85-95% and I'm not even running any programs.

Could it be a virus?
Everything I downloaded from the internet were drivers needed to run the system.

Anyways, here are a few specifications that might help:
CPU: AMD Quad-Core Procesor A10-7300 with Turbo CORE Technology up to 3.20 GHZ
GPU: AMD Radeon R7 M265 with 2 GB Dedicated VRAM
RAM Memory: 4GB
Hard Disk Memory: 1TB
