I'd suggest you to first power each rig without any GPUs and risers, only the basics: Motherboard, RAM, CPU, SSD, Power Supply and the required peripherals.
If problem persists, then the problem is either the Mobo, ram or processor.
If it's stable, in the next test, add one or two GPUs; again, if stable, repeat until the problem occurs.

This should be in the Altcoin section: "Bitcoin Forum > Alternate cryptocurrencies > Mining (Altcoins)" because a mining Rig consist of GPUs can't mine Bitcoin.

There's actually more of that empty block, specially on the older days.
The old ones were simply because there are no transaction in the miner's mempool, so they mined the block empty.
The latest are speculated that those were blocks that're mined seconds after the previous block,
like your example 660500: previous block height 660499 has the same timestamp as that empty block.

That transaction's change is too small that the dollar equivalent of it is just a fraction of the sent amount.

It's also possible if the transaction has only one output, only the recipient, no change.
You can do that: send an exact amount if you have any unspent output(s) that's a little higher (that can cover the fee) than the amount that you want to send.
But that's less likely to happen.

Disregarding the fiat equivalent, you just have to paste the receiver's address to the blockexplorer and the transaction history below will show the received amount in BTC.

Is your Electrum wallet 2FA?
Because if it is, then its "master public key" when used alone wont produce the same addresses as your 2fa Electrum's 2-of-3 multisig addresses.

No? Then you need to provide some info about the wallet/service where you've imported or generated the addresses using your "master".

That's the latest login page  
What he has is the "alias" which is different from the "wallet ID" (read the replies in page 1 to know what is it).

Or you've just pasted the wrong link?

In addition to the posts above: "blockchain explorers" (blockexplorers) can't tell which is the recipient's address(s) from your change address.
It will consider all of the outputs as the sent amount when you explored a TXID instead of an address.

With that screeching sound, you absolutely don't wanna plug and power that HDD!
That sounds like the actuator arm's head scratching the data platter because of some hardware failure, your data are being damaged whenever you hear it.

It's best to leave it to HDD hardware professionals.

This depends on what "Armory files" you have.
If it's the data directory which consist of 'databases' folder, armorylog.txt, dblog.txt, then there should be some armory wallet files in there.
a wallet file named like "armory_xxxxxxx_encrypt.wallet" is basically the wallet itself.
If it's the install folder of Armory which contains the executables, then it's useless as a backup.

For the password, it's useless without a backup of the wallet file as you've read in that sticky thread.

This has been answered but the main reason for the ridiculous fee is to ensure that there's a very high chance that it'll be displayed on top of all the transactions in that block (after the coinbase txn).
But as you can see in block height 666666, it failed to do so: 666666.
There's a transaction with similar motive (suspiciously an add) that beat it.

Based from the code [commands.py], there are only two optional arguments aside from from the language which are the --nbits and --seed_type.

By following what's written in the link, these examples should work:Without the "" at the middle, it'll take the "seed_type" as the language.

Walang tulugan?  :D

It'll be troublesome since the hacker already have access to your backup phrase, he must have restored it to a wallet that supports BIP39.
So, every time your main wallet receive a transaction, he can send it right away.

Sending it to your other account that's higher than the 10th index by creating more than 10 Bitcoin wallets in "Settings Icon->Wallets & Addresses" might do but the hacker must be monitoring those too.
So, try to convince the support (explain the situation) to let you send your Interest and Trading account balance to other wallets.

There may be more options because I'm not using the Interest and Trading feature of that wallet.

That'll work but since you've sent the funds to a new cold-storage wallet with a new seed, you'll have to create another watch-only wallet as an online pair.
Just re-do the "Create a watching-only version of your wallet" process described in your link.

It's the mix of the two: It will create a new "wallet ID" and the the BIP39 supported accounts will be added automatically.
For the custodial accounts: he just need to provide the same "identity" like name, address, etc. and pass verification using the same credentials as the old wallet and his Interest and Trading accounts should be restored to the new wallet.

Since there's no coin control and you have other unspent transactions, I'm afraid that all you can do is wait.

It's because you've pasted the address on that blockexplorer (shown in the left side of the image). It's showing that the address: 3LURV5QPTb... has sent that total amount since it's in the input (sender) side.
For the right side of the image that displays the amount in green: It happens when you've search for the transaction ID instead; the inaccurate amount is because blockexplorers can't tell which is the change from recipient address, it will show the total value of the output(s) instead. It's green because it can't also tell if your address is one of the receiver or sender.

What kind of web wallet?
Because depending on the situation, you may be able to perform a manual CPFP (Child Pay for Parent) transaction since the change has enough value:
3CPhBiQvhoFB3TC9aEpGFqbGGw6wGr1S1Y - 0.00009179 BTC

Example:
If you don't have any other balance in that web wallet aside from that change's balance and want to use that as additional fee:
just send the lowest standard bitcoin amount (546 satoshi) to any address and the wallet will spend that UTXO.
By spending it, you practically performed a CPFP that may increase the total fee of your transactions to 7-8 sat/vB.
If you have other unspent outputs in the wallet and it doesn't have a way to select inputs, do not recklessly send as the wallet may spend the other UTXO that wont help your stuck transaction.

He may be talking about the first bitcoin transaction by Satoshi and Hal but got mixed-up by the first bitcoin block.
Because both are "first".

FYI, your Interest and Trading wallets aren't backed-up by the recovery phrase, controlled by blockchain.com and can't be sent to external wallet addresses,
if the hacker successfully logged in your account for some reason, the only option he has is to send it to your "My Bitcoin Wallet" before he can send it to his own wallet.
With that, keep track of your main account's transaction history using the restored wallet in Electrum, any transaction past the last outbound transaction may be your Interest account's balance going in to the main wallet and another one being sent out.

BTW, you won't be able to display images 'till you become a "junior member" (next tier to newbie).
Those will be displayed as links instead.

Hmm, if it's their website's issue, it should've happened to more users; eg.: I have no problem logging-in & your new account works.
The hacker might have done something to your account that's why you have trouble logging in to any device.
Contact blockchain's support for help, log-in issues can be solved using their CS.

Or clear your browser cache and try to login again, you may as well try to use a different method to connect to the internet.
Other than that, I have no other idea.

Only your normal accounts will be restored to Electrum like "My Bitcoin Wallet", if you have created more accounts (except Trading and Interest), you can change the derivation path's account index in Electrum.
But I believe that it's not the solution to your case.

As for the Interest account, you should try to log-in in the web version using a device safe from malwares or viruses.
You might have a malware that messes with your QR Code reader, browser, etc.

In addition to this, @posi, check the transactions that he had quoted "done" in a blockexplorer with a "miner tag" feature (eg. blockchair.com).
First paste the transactionID, then click the block height where it was included, and look for the miner of that block,
if you're seeing random pool names for every transaction he "accelerated", then you know what it means.

Note: the miner tag may be inaccurate depending on the blockexplorer.
