Perhaps I misunderstood then. I thought it BSODs on battery and on AC, just less frequently on battery.

Does it crash only when the AC is connected and not on battery? If that's the case, then I apologize to everyone.

I'm going to let this stew for a bit.

If you do get a BSOD while running on battery only, please post the information.

If you don't get a BSOD for a week or more, then it's time to take the machine to a shop, have them test the power block, the power jack, and the motherboard.

It would benefit members if you could post some screen shots of the Intel Rapid Storage Technology (IRST) utility
IRST User Guide

This is mostly a "look but don't touch" request. If in doubt, hit the cancel button.
The only real operation is the 2nd to last bullet - verify.

Start menu > Intel > Intel Rapid Storage Technology
  1. Help button > About button
    Close the help window
  2. Main Window > Status
    There should be two devices with green checkmarks - these are RAID (mSATA cache and HDD)
    You can click on the devices and that should show the manage window for that device
    If not, see what the manage button presents
  3. Main Window > Manage
    There's not a good explanation in the manual, but I suspect the Verify and Repair option is under manage.
    You have two choices
    Verify Only
    Verify and Repair

    I was trying to figure out how to check the RAID pair and this looks like the place to do that.
    Please run a Verify Only pass on both the mSATA and HDD
    - you might not have to do both since they are RAID, but the manual isn't precise
    If any errors are reported, post the information presented.
    I'm not 100% sure that you want to run the Repair, the information from the Verify will guide that decision.
  4. Main > Preferences
    There's noting about this in the manual, so just post what shows up. We can drill down later if necessary.

Thank you for all of your help - I've refreshed old memories and learned new things about IRST from this exercise.

I am holding my breath right now. Last night, I downloaded the IRST driver. I am on AC power, and I have not crashed in about 35 minutes. This is the most progress I have seen yet. I really do not want to jinx things, so I'll probably leave it alone for now. I will keep you guys posted... *crossing fingers*

x64 (6.3.9600) Win8.1 Pro & soon dual boot x64 (6.1.7601) Win7_SP1 HomePrem IRST - only downloaded or installed?

I've put the reinstall without IRST on hold until it's determined if the BSODs are hardware related
(run on battery only for a week or two - Zero crashes most likely means a short in the power jack)

When you get the chance it would still be helpful to see the IRST utility screens. No rush, we're in a wait and see mode.

You'll have to take a breath sooner or later

Sorry, yes. I installed that IRST driver, and things are STILL going well, both on power or battery!

This weekend, I'll see about posting the screen shot you requested!

Great news, Kenin.

Hopefully your machine runs well for the long run, if not.... you know where we are.

No rush on the screen shots, when you get the chance.

Hello! Things are still going fine, regardless of AC or battery power! If it continues another few days, I'll have to see about a few things. Disk Cleanup, saving a system image, and perhaps making some kind of back-up...

Anyway, I was just in a "look but don't touch" mode, so I'll provide some screen shots along the way here.

This is my Status screen.

This is my Manage screen. Even with their Help instructions, I could not find anything to do with Verify or Repair. Weird... (I did click the "Advanced" pull-down option to show any more potential goodies.)

Attachment 326219

Anyway, things are still going well! I'll be back to check in, but I wanted to give a huge thanks to all who helped me along the way!

Excellent news Kenin and you are most welcome
... AC power was a perplexing component of trouble shooting.

A few refs for things you mentioned:

Disk Cleanup - Open and Use
Backup Complete Computer - Create an Image Backup

Pretty much anything you want to do on win7 is covered by one or more threads in the
Tutorials subforum.
Welcome to the Windows 7 Forums Tutorial Section
Windows 7 - Tutorial Index

Thank you very much for posting the screen shots of the IRST utility.

RAID0 (cache)
SATA array
Acceleration enabled - device=mSSD

Now all I have to do is figure out what that really means

@Steve (essenbe),
Kenin did all the work, I was but a student learning along the way
