    Hello my computer has recently been giving me BSOD 100% of the time when I try the following: Running Windows Defender Scan, Running Spybot Scan, & everytime I try to run in safe-mode. However, the computer also will randomly give me a BSOD (maybe once an hour?) while I use the PC which is the biggest issue of concern as I use this computer for gaming and for school.

    Below are 3 sketchy files in my System32 that I believe are the root of the problem, screenshot is below. the acovcnt file can be easily deleted but will come up again when the system restarts. I cannot delete the 2 weird named files even if I tried. An error will say the file is in use then when I close off the files, a dllhost file in windows task manager processes comes up with the description "COM Surrogate" If I close that program it will process as if the file is no longer is in use and is ready to delete, but it never will delete (same goes for trying to rename the file).

    I am assuming I will need to post some of the BSOD errors, but it is not always the same blue screen so maybe if I can get a little direction as to which ones I should post, it may help.

    I am very PC literate as I have been a PC gamer most of my life, I have always been able to remove malware files from my family's PCs but this one has been tricky (I probably only do elementary removal tactics!) I have also tried to run chkdsk but it stated there were no bad files & Avira says there are no Viruses when it scans.



    I appreciate any and all help. I will post more information upon request I hope I have been somewhat clear here.

    GPU or IRQ problems comes first. BSOD displays error codes tells more than simple speculation [IMG]

    Do the data dumps I provided have this information? I am getting a variety of blue screen errors (but I believe they are all related to some sort of malware as my pc never BSOD until about a week ago) If not I guess ill have to provoke some BSODs by running scans and copying down the technical information.

    Oh I see... Is there a way I can get screenshots of my BSODs or do I need to write down the errors? There are a variety of BSODs like i mentioned earlier and some do the physical dump fast so It would probably take a few BSODs to write down the entire information.

    all those errors points to same thing: random access memory (RAM) modules that are installed on your computer are faulty.

    Here is a resolution available from Microsoft for the above error, you had mentioned. If you continuously getting the BSOD as you have mentioned then try to back up all your important data in a removable media.

    If the normal troubleshooting steps does not fix the issue, you may go for the the parallel reinstallation of the Operating System. It wouldn't let you loose your data (e.g music, ms office files, snaps, videos etc.) but you would loose all your third party programs. But you may reinstall them as well. Let me know, if that does work for you.

    Wait! I've analysed these logs, there may be more than one problem, but the most obvious problem is caused by the following driver:
    The driver belongs to Daemon Tools, well known for causing BSOD's including memory corruption. The driver can also perceived by many security software as malicous due to it's "rootkit like" characteristics, and they will attempt to block it's activity. This will also leave the system unstable, usually resulting in crashes and blue screens. Suggest removing this software, use your original CD's. Use MagicDisc would be a much more stable alternative if you need to mount an ISO.

    The file acovcnt.exe is not malicious and comes bundled with ASUS video enhancement software. The other two are GUID's. There's nothing wrong with these, please leave them be.

    Thanks everyone for their help in the matter so far. I went on vacation for a week (didn't bring laptop) then when I came back I started getting occasional BSODs, now its pretty much every hour I get one. I thought it was a virus because it was a variety of BSODs, but now I'm thinking it was the large amount of window updates that occured when I returned from vacation and turned on my laptop for the first time in a week. Also my Avira AntiVir returns its scans with no virus detections.

    @madmonkey
    Thanks for your review on the logs. I had Daemon Tools on my computer a while ago, but I removed the program around a year ago as I upgraded to MagicDisc (which is also now uninstalled as I don't download ISO files anymore). Thanks for letting me know those files are okay :)

    If there is anymore information I can provide please let me know :), would steklo be correct about the RAM modules?
