Intermittent BSOD, trouble resuming Windows, Difficult to Diagnose

System Spec:
- 64 bit
- I built the machine August 2010, I have not reinstalled the OS since.
- Full Retail Version of Windows 7
-

Hello Everyone,
I have been experiencing problems with this machine since about a month after I built it in August 2011. At first I would get a BSOD just every once in a while. I am at architecture school and I didn't have time to address the issue, so I just kept a diligent written log of every time I noticed it happening. I have included that as an attachment. You'll notice that there was not an obvious trigger - it would not crash as soon as I opened something, or as soon as I tried to use the sound card. It would happen both while I was working in Adobe Illustrator, and when I left my computer idle to go grab a cup of coffee or something like that. I have included all the dump files I have as attachments.
Recently, however, Windows has had trouble resuming. I can't figure out exactly what is happening because it hasn't happened while I was at my computer yet. But, pretty much every time I return to my computer after a 10 minute absence, I come back to a black screen with a blinking white underscore in the top left corner. I think it has something to do with the machine going to sleep and having trouble resuming windows.
Another clue, which I've researched a little bit, is that I think I heard a single beep the other day. Granted, I'm in a studio with 50 other people and there are cellphones, headphones tons of computer and all kinds of noise, but I'm sure enough about what I heard to include it here. The forums I checked suggested this was a problem with the RAM.

UNEXPECTED_KERNEL_MODE_TRAP (7f)
This means a trap occurred in kernel mode, and it's a trap of a kind
that the kernel isn't allowed to have/catch (bound trap) or that
is always instant death (double fault).  The first number in the
bugcheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a *portion* of those codes:
If kv shows a taskGate
        use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
        use .trap on that value
Else
        .trap on the appropriate frame will show where the trap was taken
        (on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.
Arguments:

The problem is due to your graphics card/graphics card driver. These faults are usually hardware related, especially due to memory problems. It may also be that the graphics card or a RAM module is not seated properly. Another possible cause is an underlying driver that is incompatible with Windows.
Thanks to Dave76 for help understanding possible causes.

Your crashes could be a result of the BIOS needing an update, the graphics card drivers needing an update, or your chipset drivers needing an update. Begin with the following steps. Post back after each step and wait for a response from us before proceeding to the next step.

• If you are overclocking anything, please stop.
  
  
  
• Install/re-install your latest graphics card drivers. We ask that you re-install if you already have the latest drivers because the drivers on your system may be corrupt. Use the following steps for installing the drivers.
  
  1. Download the latest drivers for your display card(s)
  2. Click Start Menu
  3. Right Click My Computer/Computer
  4. Click Manage
  5. Click Device Manager from the list on the left
  6. Expand Display adapters
  7. Do the following for each adapter (in case you have multiple display cards)
     
     • Right click the adapter
     • Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
     • Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
  8. Restart your computer after uninstalling drivers for all display cards
  9. Install the latest driver for the display cards once Windows starts
  
  
  Alternatively:
  
  1. Login as an adminstrative user
  2. Download the latest drivers for your display card(s)
  3. Click Start Menu
  4. Click Control Panel
  5. Click Hardware and Sound
  6. Click Device Manager (the last link under Devices and Printers)
  7. Expand Display adapters
  8. Do the following for each adapter (in case you have multiple display cards)
     
     • Right click the adapter
     • Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
     • Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
  9. Restart your computer after uninstalling drivers for all display cards
  10. Install the latest driver for the display cards once Windows starts
  
  
  
  
• Download and install HWiNFO64 Download to check hardware temperatures.
  
  
  
• Use FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net to test the graphics card GPU. Then use the |MG| Video Memory Stress Test 1.7.116 Download to test your graphics card memory.
  
  
  
• Run Hardware - Stress Test With Prime95 to determine any hardware problems. Run all three tests for a few hours each. If you get errors, stop the test and post back here.
  
  
  
• Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).
  
  
  
• An underlying driver may be incompatible\conflicting with your system. Run Driver Verifier to find any issues. To run Driver Verifier, do the following:
  
  a. Backup your system and user files
  b. Create a system restore point
  c. If you do not have a Windows 7 DVD, Create a system repair disc
  d. Run Driver Verifier
  
  If Windows cannot start in normal mode with driver verifier running, start in safe mode. If it cannot start in safe mode or normal mode, restore the system restore point using System Restore OPTION TWO.
  
  Thanks to zigzag3143 for contributing to the Verifier steps.
  If you are unable to start Windows with all drivers being verified or if the blue screen crashes fail to create .dmp files, run them in groups of 5 or 10 until you find a group that causes blue screen crashes and stores the blue screen .dmp files.

Also, when was the last time you blew dust out of your system? To remove dust, follow the following general procedure. If you have a desktop bought from Dell, HP, Sony, Lenovo, etc. make sure removing the desktop casing will not void your warranty first. Call the company if you are still under warranty and ask if it is okay to remove the casing and blow dust out. The procedure described is fine for laptops; just make sure no stickers are on panels saying if you remove the panel it will void the warranty.

1. Shut down and turn off your computer.
2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
4. Remove the casing for a desktop, or remove any screwed on panels and disc drives for laptops.
5. Blow out the dust inside by using a can of compressed air or a low pressure compressor. You will want to put the computer on a desk or table so you can maintain the can in an upright position if using a can of air. Blow into all crevices on the motherboard, heat sinks, cards, modules, etc. for a desktop. Blow into vents, opened panels, disc drive areas, USB ports, and the keyboard if it is a laptop. You may also want to blow inside the disc drive by replacing the drive to the laptop, starting the computer, opening the drive, and then turning off the computer and removing all power as described above including the 30 second power button step. For a desktop, you may also want to blow inside the disc drive by starting the computer, opening the drive, and then turning off the computer and removing all power as described above including the 30 second power button step.
6. Replace casing for the desktop. Replace panels and disc drive (if you have not already done so) for the laptop.
7. Plug power supplies in. AC adapter for the desktop. Battery and then AC Adapter for the laptop.
8. Start the computer and see if performance is better.
