Windows 7: BSODs at random moments with multiple error codes

BSODs at random moments with multiple error codes


First of all thank you for taking the time to read my thread. The problem I'm having is that I'm experiencing BSODs on my desktop PC at different moments. Sometimes it happens at startup, other times it happens while watching a movie on YouTube or during a Skype call. When looking into the minidumps, I see that many BSODs relate to ntoskrnl.exe, but not all of them.

I'm running a quite old pc (7 years), but it has always performed well and didn't experience any problems with it since I reinstalled Windows 7 64-bit about a year ago. Only lately it has been giving problems.

What I tried so far:

- Run Memtest86, no errors
- chkdsk on the boot HDD
- Run sfc /scannow command, no errors found
- Remove any overclock on my system
- Replaced many drivers I was suspecting to cause trouble, such as my Graphics card driver (now reverted to an old version I'm sure of it was stable on my PC, have tried the newest one), SATA RAID drivers & network drivers.

I'm not sure whether it is related, but almost everytime I boot, either Dropbox or Skype crashes.

Does anyone have a suggestion on the cause or solution?

Thanks in advance,

Welcome to SevenForums

Please remove anything related to acronis on your computer during the time of troubleshooting. From one of your .dmp shows that it's contributing to these BSOD-s as well. You may have to reinstall latest version once we know the computer is stable.

Hi Koolkat, thanks for your reply.

I'm in the process of following your instructions. A newer BIOS is not available to me, and all drivers you suggested I had installed them first, but reverted to older drivers when problems started to occur. Same goes for Acronis, which I installed to backup some data since the BSODs started happening.

I ran checkdisk, and both rootkit and virus scanner. Monitoring temps I did already, which seem to be OK too even under heavy load. I'll will complete your suggestions and install most recent drivers.

Today I also installed a new SSD I ordered a while ago (by migrating my current windows installation to the new SSD), and after that I didn't experience any BSODs anymore. It's too early for conclusions but it might have solved my problems.
