Hello. I have windows 7 professional 64 bit and every time I turn on my pc, the RAM usage slowly climbs to about 80%. This takes around an hour and stays at that level, even if I close all programs, until I reboot.
- There is no noticeable program in the task manager using up all the RAM
- I have run multiple virus, malware and spyware scans and nothing has come up
- I have removed all startup programs and rebooted and the problem still persists
Anyone got any ideas what is causing the problem?
