PC slow, hangs after several hours of usage.

[HK77]

Ok so, this past week my computer started to get slow after being on for some random amount of time. It doesn't happen after I do anything, just during normal usage. Start menu items will take from 3 seconds up to a minute to launch.

Performance is fairly normal:
CPU usage could be 0-3% for firefox (rest on idle)
Ram 15-25% running Firefox, Steam, Logitech stuff, explorer, host services, etc.

-Resource monitor seems fairly normal.
-Windows up-to-date.
-Bios up-to-date
-all known drivers up-to-date
-Mbam = nothing.
-sfc /scannow = nothing
-Registry cleaned
-I only have 10k files indexed.
-120gb OCZ Vertex 3, 70gb free. Firmware updated.

Temps are normal, drive health is good.


I've run out of ideas. Thanks for any help.

I am sorta taking a shot in the dark here but it does sound like it could be a not enough ram issue. How much ram does it show you are using and how much is installed?

We have very similar specs, please have a look at the drop-down menu.

Takes fair time to complete andsome leave it running overnight.
