0.13.1 sync problems, nearly finished, but stopped up several times

[Hanslo]

I had to reinstall my windows, and no am I trying to install my Bitcoin Core. First, I wonder why there is 2 shortcut, Bitcoin Core and Bitcoin Core (testnet)?

I have problem to start up my wallet. Got this error:

This is after I used my wallet back up.

Anyone know what to do to fix it?

This was recently added. Just ignore the testnet shortcut, you probably won't need it.

You have a corrupt block. The easiest solution is to delete the entire "blocks" folder inside of the Bitcoin Core data directory and then let Bitcoin Core resync the whole blockchain.

I deleted the "Blocks) folder, but still problems:

Try deleting everything in the data directory except for the wallet.dat file.

[Hanslo]

Ok. Also tell you that I'm useing datadir=e:\BitcoinData because I don't like to fill up the c disk.

Have done what you told me and it's downloading now, but it will take some hours

Looks I have to start over again:

Can my Norton virus protection do some problems?

Can my Norton virus protection do some problems?

Seems unlikely to me.  It may be that your hard drive is failing...  You shouldn't have repeated issues downloading the chain like that.  Maybe you should try scanning your hard disk for bad sectors?

Actually Antivirus can and have caused issues in the past as there are some virus signatures in the blockchain.

Op add the bitcoin data directory to your Antivirus exception list.

Also, please do not make duplicate threads for the same issue. I have moved your other thread to the trashcan.

I suspect 0.13.1 to be the reason. I'm back to 013.0 and it look's to be soon finished with resync.

No, it was not so easy. 39 weeks left it stopped up, but looks still working:

Can my Norton virus protection do some problems?

Seems unlikely to me.  It may be that your hard drive is failing...  You shouldn't have repeated issues downloading the chain like that.  Maybe you should try scanning your hard disk for bad sectors?

Maybe. I'm doing a defrag now.

This is somewhat anecdotal, but it may be helpful anyways.

I had similar problems a few years back, and it turned out to be bad RAM.

I wasn't having any other PC-related problems; no crashing, no problems when gaming, just problems w/core. I eventually ran memtest86+, and discovered a single bit error (in all 16GB) which matched up perfectly with the single-bit error (in terms of its position in a 64-bit word) I had also tracked down in my block files.

Although I was surprised, perhaps I shouldn't have been. Unlike most software, Bitcoin does a whole lot of checking/hashing of its block data, so it's much more likely to uncover hardware problems on a PC than most any other non-diagnostic software.

Win 10 has a memory diagnostic tool built-in. Just click the Start, and type "diagnostic", and should show up (it will require a reboot). Memtest86+ is probably more thorough; it's a little harder to set up, but worth the effort IMO.

When scanning my harddisk it was repaired for a bad sector or something. I started to resync again, but it stopped up when I was 29 weeks left. Bitcoin Core asked me to start again and I answered yes, so it's on processing blocks again.

Maybe the problem was that I was gaming and used to much memory?

Have also used the "diagnostic" and it found no problem with memory.

I have now installed Bitcon Core 0.13.1 on my C drive choosed destination for BitConData to my ssd I drive. Maybe I will have better luck this time?

This is realy raffle. If my wallet was empty I wouldnt tried anymore. It's terrible.

If you really want to just extract your wallet and not bother with it anymore, you could give someone the wallet.dat (make sure they're trusted) and install Electrum (SPV client). They can then send you the funds.

Were can I find the support team?

There's no *support team*. Usually the way to get help is either this board, IRC or the issues page on Github (I see that you've already created an issue).
