PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

 

Primary monitor randomly goes black

Got a monitor issue. Looked at other posts about this issue be could not find anything addressing my issue. Over the past few months, my primary monitor randomly (no pattern to the issue) goes black but the led shows it to still be working. Secondary monitor is working. Only way to get the primary back is to reboot the computer. I tried reversing the DVI-D cable but no luck, primary still goes black. Regardless of which monitor is set to primary, that is the monitor that goes black. The monitor set as secondary never goes black. Any ideas?

 

PC hibernates / goes into sleep mode upon logout / screen lock

I am using my work computer. It's a laptop with a power connection (not running on battery.) The laptop is hocked up to two monitors (a total of three monitors, counting the laptop's own screen - I usually keep my laptop closed, however.)
Since I am at work I always lock the screen when I leave my computer. (I use the windows+L shortcut to lock the screen.) This all works fine.

However, after about a minute the computer goes into sleep mode / hibernation. At least I think it does, because the two monitors goes black - and it takes a few seconds to "wake up the system" (the monitors doesn't come back to life immediately when I press a key on the keyboard / move the mouse, as they would if a screen saver was active.)
This is very annoying if I step away from my computer for only a short while (like going to the bathroom.)

Here's what I want:
With power (not running on battery):
When I lock the screen, I want the screen to stay on for 1 minute, then go to screen saver for 15 minutes, then go to hibernation/sleep mode.

Without power (running on battery):
When I lock the screen, I want the screen to stay on for 1 minute, then go to screen saver for 5 minutes, then go to hibernation/sleep mode.

My best bet is that this is some sort of power saving scheme thingie, but I can't seem to figure out how to configure it to do what I want. Can someone please help me with a step-by-step guide to configure my system the way I want? Thank you.
