Did you run Prime95 I mentioned in my earlier
post?
Your CPU Temp (CPU 45c) looks a little high,
are you using the stock Intel Heatsink and Fan?
If you are not using Intel's stock heatsink and
since assembled this system yourself what did
Heatsink and Thermal paste did you use.
Prime95 "Stress Test"
"FREE MERSENNE PRIME SEARCH SOFTWARE"
http://www.mersenne.org/freesoft/
Download and unzip. It's a standalone .exe file
when you first start this program you will see
a "Welcome to GIMPS" window. bottom right click
on the "Just Stress Testing" button. In the
"Run a Torture Test" window select the "Blend"
option. Leave the "Number of threads to run"
at 2. Don't forget to start SpeedFan before running
Prime95 so you can monitor your CPU temperature.
When your done running Prime95 use the menu to stop
the test, if you don't and just X out it will still be running
in the background in which case you will need to open
Task Manager to Kill the Prime95 process.
I Personally turn my PCs off at night even though each
PC has it's own UPS power backup unit, why keep the
system running when your sleeping.
