Random BSODs

It is expected that some other person will take the charge of your issue. If none of them posts in between, I will see the dumps again, when I will be back home.

Yes, Accelerometer.sys is HP Mobile Data Protection System Accelerometer driver, and it is always troublesome. If you are sure that you haven't installed those components, delete them manually in drivers folder. Also, sometimes some malware say rootkit may fake any driver. As they resides in the BIOS, a full formatting of the HDD cannot keep it clean with 100% certainty. So, scan the system for possible virus infection.

• Anti-rootkit utility TDSSKiller
• Windows Defender Offline

When done, Clear COMS.
It will help you to get rid of any possible rootkit.

Also, the version of intel RST you have installed (Had I been in place of you, I would not have installed it at a clean reinstall, until and unless I use a RAID setup) is problematic. First get rid of intel rapid storage.

1. Right click on "my computer" icon and click "manage" on the context menu.
2. It will open the "computer management" window.
3. Select "Device Manager" in the left pane, It will list all the existing devices up.
4. Expand "IDE ATA\ATAPI Controllers" by clicking on the triangle in front of it.
5. Select Intel device item under it, right click, uninstall.
6. Continue the process for all intel device items.
7. Now restart the computer. At restart, windows will auto configure the appropriate system driver, msahci.sys.

Then, if you really need Rapid Storage, download and install this particular version only.


Apply the latest version of nVidia display driver.
You may download it directly, from our forum link Latest NVIDIA ForceWare Video Drivers Windows 7; or you may opt for the Option 2 of Drivers- Download NVIDIA Drivers for “Automatically find drivers for my NVIDIA products” (it requires java installed).




In short, you seem to have installed some unwanted elements at the clean reinstall. During driver installation, dont install anything other than the chipset, network, audio, graphics. Windows 7 does not need anything else to run, whereas their presence may cause various issues, you can see it.

You may keep the USB 3 driver, and search for any possible updates in Intel Download Center.

Try uninstalling Intel Rapid Storage in Control Panel > Programs and Features.

Also, have you deleted Accelerometer.sys and followed the other steps I suggested you? If so, let us know how it works. If it crahses again, upload the crash dump.

Intel RST was uninstalled, as were the other Intel programs.
The drivers still exist in windows/system32/drivers, though. I just tried manually deleting them (after creating a restore point), which after restart caused BSOD loop, am in start up repair now.

TDSS Killer found no threats. Haven't don't defender offline yet, as I need to download the updates for it.

And yes accelerometer.sys was successfully deleted.

iaStorF/iaStorV won't delete without bsod on restart.

Dont delete the iaStor drivers manually from the driver folder. After uninstalling RST, do a Cleaner and registry cleaner run using CCleaner. It will do the necessary actions hopefully, and safely.

Let us know the situation after the startup repair.
