Is there any error message when you try to start bitcoin core? Can you post the your debug.log? The file should be in C:\Users\YourUsername\AppData\Roaming\Bitcoin if you didn't change the datadir location.

i still cant upload all code

[cakir]

Why are you starting mining with core wallet?
if you're not starting it manually, open the debug window and enter this command: "setgenerate false"

Also it seems like your blockchain data is corrupted (because of powercut), There're 2 things that you can try;
1- start bitcoin core wallet with -rescan parameter. If it doesn't work then;
2- clean the blockchain's folder (don't forget to copy wallet.dat to another location) and resync with the network.

He has essentially done these by reinstalling core.

bobby88 - what happens when you run core? Is there any error message on the screen?

[bobby88]

Yes ,
the error codes are This application has requested the Runtime terminate it in an unusual way
please contact the application's support team for fo information. dialog box appear when bitcoin-qt try to sync , cant upload with prntscrn.com in here

[achow101_alt]

That seems odd. Maybe it is a corrupted installation. Try reinstalling it again. Make sure you delete the bitcoin datadir before reinstalling. Also backup your wallet.dat file.

[bobby88]

Its 4 times i try to re install it again , geez

[bobby88]

anyone ?

[achow101_alt]

If you have tried reinstalling several times, a reboot might help. However, this may also be a hardware problem. It is possible that the sudden power outage caused some issues with your computer. For example, sudden power loss to a HDD can cause the reader head to crash into the disks and cause them to be damaged. Try installing a different wallet software and import your private keys from your wallet backup.

[bobby88]

try to sync with the network now , failed to use my wallet back up, everytime i put this file , it crash again

[cakir]

Can you post the last 10-20 lines of the log file?

According to your log, it's syncing. Has it crashed yet?

[bobby88]

thats the last debug log before i put them to recycle bin , everytimes i try to put the wallet.dat its crashing somehow

[cakir]

Your wallet is trying to solomine with unsynced chain. Probably because of your bitcoin.conf file.
If there's a line says: "gen=1" on that file; either change it into "gen=0" or just delete the line.

Also do not put wallet.dat file into blockchain folder while the core wallet is running. Start it and let it create folders, then close it. copy wallet.dat (and replace the new one) and then start it again.
