Windows 7: BSOD every day, different each time

22 Oct 2013   #1

Windows 7 Ultimate x64
BSOD every day, different each time

I've got a real problem here. This machine BSOD on every shutdown and every morning. I completely rebuilt the machine. New motherboard, i5 cpu, new RAM, everything. Reinstalled Windows 7 from scratch. Nothing was restored from backup. It is completely new hardware.

It still bluescreens multiple times a day!

I have tested the power supply voltages - ok.
Virus test with Sophos and Comodo - ok.
SFC /scannow - ok.
RAM test, 10 hours of testing - ok.
Malwarebytes - ok.
Western Digital data-life-guard drive test - ok.

When I look at the crash dumps, they seem to point to some application, like Bing desktop. I remove that application, then the next BSOD is for another application or driver. Rinse and repeat. I'm really stumped on this one.

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

Hi Arc, thanks for responding. I did in fact test memory overnight and it passed. But again, this is even NEW HARDWARE. Completely new motherboard, cpu, 8 gigs of RAM, the works. All brand new.

Still bluescreens.

As a further test, do a Clean Reinstall - Factory OEM Windows 7 .... do exactly what is stated there. Dont install Intel and Marvell storage controllers.

Let us know how it goes.

I installed a new hard-drive on Saturday and did a full reinstall of Windows 7.
I only installed the OS, FireFox, and Office 2010, and Sophos antivirus.
Then I added Java and Flash player. Did Windows Update.

It still blue-screens on every boot.

Did you use memtest86+ per the tutorial's instructions? If not please do so. New hardware can be bad too and you BSOD is blaming memory corruption which can be memory anywhere in the system from RAM to the GPU memory. You said the voltages are ok, what are they in Windows? This free program can show you. HWiNFO, HWiNFO32 & HWiNFO64 - Hardware Information and Analysis Tools

Pull all the PSU cables, RAM and GPU and reinstall everything taking extra care to confirm they are fully seated/connected.

To better help us to help you would you please add your systems specs? Here's the correct way to do it. :SystemInfo See Your System Specs Under System Manufacturer/Model Number add whether it is a desktop or laptop and whether self built. Very important

Log in to Seven Forums and you will be able to transfer the info directly to the specs page in your profile from within the System Info app.

Your System Specs here.

After doing this your specs will be available in each of your posts.

Hi Basildane, welcome to 7F! :)

The memory corruption from your .dmp's indicates either faulty memory and/or drivers, you're getting a pool leak from somewhere: Troubleshooting Pool Leaks Part 5 ? PoolHitTag - Ntdebugging Blog - Site Home - MSDN Blogs.

To narrow this down, Please, uninstall everything, but the OS, we want a "Bare-bones" system. If you are having BSODs on every startup you may just have to do another "Clean Install" to work around the BSODs.

Personally I would like to see a clean install just to see if the machine would startup without a BSOD, then do this list one at a time with restarts after each to see where the BSODs start:
  • Run Windows Updates.
  • Use Internet Explorer only, other browsers can come later.
  • No Office 2010. It can come later.
  • Please, no java or flash especially java, unless you are a gamer and one of the games you play requires java, you would be surprised at how well you can live without java. Either one of these can come later.
  • Don't install the storage controllers as Arc has suggested, they can come later.

If you have a BSOD before you even run the Updates I would suspect a hardware failure somewhere.
  • Did you check for compatibility of all the hardware components before you purchased them?
  • Did you install the CPU?
  • A cracked Motherboard (MB) i.e. bad solder joints.
  • Mis-matched RAM, it can happen even straight from the vendor.
  • Everything plugged in correctly?

I see Britton has replied, hopefully we have given you some "food for thought".

Got it.

And thanks for the HWiNFO64 tip. I'm looking at that now. Really nice program.
Will report back. Thanks again.

I found a pattern. The BSOD always happens after boot, and only if the machine was off overnight. It rebooted fine if only off for a minute or a few hours. So even though the memory tested good, I swapped the RAM anyway, and sure enough, that was the problem. Thanks all for your suggestions!
