Intermittent BSOD at startup - Increasing frequency

[acousticdj]

Hello. I have a custom build Windows 7 64-bit. Been getting BSOD with increasing frequency at startup. Always able to reboot and start Windows just fine. After rebooting I get the following error message:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.256.1
Locale ID: 1033

Additional information about the problem:
BCCode: 1000007e
BCP1: FFFFFFFFC0000005
BCP2: FFFFF88004A2DDB1
BCP3: FFFFF880035623D8
BCP4: FFFFF88003561C30
OS Version: 6_1_7601
Service Pack: 1_0
Product: 256_1

The BCCode (1000007e) is always the same. The BCP 1 code is sometimes the same. BCP 2,3,4 codes are always different.


I have done/checked the following since it started:

Installed latest MOBO BIOS
Installed latest video card driver
CCleaner: Ran Registry checker/cleaner: No issues
Installed all Windows Updates
Ran Windows "Auto Startup Repair": "Could not automatically repair"
Ran Windows "Check online for solution": "No solution found"
Ran Fixboot / FixMBR in command prompt: Didn't help
Ran short Windows Memory Checker and MemTest86 memory test: No issues
Ran PCWizard: All seemed fine
No "question marks" in Device Manager -- All devices show working properly and most recent drivers
Looked at "Dump files": couldn't make any sense of them
Windows Performance Monitor looks fine
Checked SSD for disk errors: None found
Looked around in BIOS - didn't change anything. All looked fine (as far as I could tell.

SYSTEM:
AMD FX-8120
Gigabyte 970A-UD3
32GB DDR RAM (4 x 8GB sticks) - Board maxed
NVidia GeForce GT 440
OCZ Agility3 90GB SSD


Possible next steps:
Longer RAM tests
Run Prime95 test - Not familiar with this process though
Reinstall OS - want to avoid if possible
Start removing one stick of RAM at a time and see if it helps


BSOD is just annoying right now. As mentioned, reboot always works but seems to be happening more and more.

Why does a simple reboot always temporarily fix the problem? If there was a problem with hardware or drivers wouldn't it "stay broken" or shut down/freeze at times other than at startup?

THANKS

The getting worse bit could be due to a failing power supply causing memory errors. Other common causes for this error are using windows XP wireless drivers. Try disabling the wireless driver and see if this cures the problem. This error can also be caused by corrupt system files, try running as the administrator in the command prompt" SFC /scannow" If you find any errors then they are probably caused by faulty memory, and finally if possible try another power supply after you have tried the other things.
