My computer crashed while downloading blockchain now daemon wont connect and says check log files for info. I can't find log files. Should I just delete blockchain and start all over? I'm unable to use my computer desktop while the wallet is open because it uses so many resources. Latst GUI wallet. thx

If the system crashed during the initial sync, the blockchain is likely to be corrupt. A salvage attempt can be performed, but does not guarantee to repair the chain. Probably best to simply delete the blockchain file (data.mdb) and start from scratch.
