UPDATE: I had another BSOD with only Firefox open. I will post another article when I complete my investigations.

This crashes may be just a coincidence. If you are using Gridcoin wallet without problems I encourage you to keep using it. I also encourage everyone for backing up all his important files on a regular basis, this is one of the most important security measures for every electronic device.

I have been staking Gridcoin with my Windows wallet for a few days, only several hours per day, and my computer has crashed two times while having Gridcoin wallet open. The first one was only few minutes after starting Windows(10 64 bit), I had many programs open at the same time (Gridcoin, Storj Share, Firefox and Thunderbird), then I got a KERNEL_SECURITY_CHECK_FAILURE Blue Screen Of Death. Then the computer restarted but few minutes idling after the start finished, without opening any programs or files, it showed another BSOD. I finally managed to boot up in safe mode thanks to the Windows 10 installation disk by using this guide , I used chkdsk and then I managed to start Windows at normal mode.

Some files were corrupted, including my encrypted passwords at Firefox, fortunately I had a backup of most of them, but not for my Openledger account r0paga The dump file was also corrupt and I did not get any additional info from Windows Event Manager.

My accidental contribution to crypto graveyard, the coins were collected thanks to @virtualgrowth giveaways.

The second time was few minutes after waking up my computer for being suspended, I only had Firefox(Youtube) and Gridcoin open, suddenly the screen get frozen and the speakears started to buzz. Not even Ctrl+Alt+Supr worked so I had to keep power button pressed.

The next time I booted the computer it worked fine and I did not found any useful info at error reports either.

I do not have any evidences about the cause of both crashes, but since my computer did not crashed for months before, Gridcoin wallet is very likely the problem.

So I have saved all the logs I collected, and I am going to move my GRC to Coinomi, which is my favourite multicoin wallet for smarpthones, leaving a little amount of GRC just in case I do more debugging. I also opened another Openledger account, rop4ga, and saved a copy of the password, two copies of the backup file and one brain key wallet.

I may sell some GRC when the prices stabilizes, I am considering starting a new project in Steemit but for that I will need some liquid Steem to start with. I am also looking forward for autum to start mining because with current temperatures BOINC crunching in my small room is not a good idea. I do pool mining so the Gridcoin wallet is not a problem.

My intention is not to blame anyone for that, but just explaining my observations. I am not interested at running Gridcoin wallet anymore, at least not in Windows, however if any Gridcoin developer is interested about investigating that, I offer my cooperation.

Thanks for reading and do not forget about making backups.
