The login is shit though. Captcha and auto-logoff on timeout makes it a terrible unusable exchange for me.

Did you undervolt the videocard? Did you check temperatures while mining, with Gpu-z or HwInfo?

You may have damaged it...

Remove other cards and plug this one directly on the motherboard, PCI-e 16x. See if it boots and displays the desktop at least. Then see if it shows as VGA or AMD Radeon

Without your knowledge, you were stolen from your parents at birth and automatically became the judicial property
of a commercial company pretending to be your government.

In order to do this, they have to persuade the human to enter into a contract with them, agreeing to pay them
money, essentially, for nothing in return. Their main trick is creating a fictitious legal identity using the name of the
human. This is done by creating a “Birth Certificate” in the same name.
[...]
In spite of their mistake, the fictitious legal “person” produced by creating the Birth Certificate document, the
human who has the same first and last names as those recorded on the birth certificate, has no actual link to that
document unless he can be tricked into agreeing to be linked to it.

Deception of the Name: If you go to a Court (which is a Corporate place of Business) as the Accused, you will
be asked to confirm your Name, quoting the full name shown on your birth certificate, which is the LEGAL
PERSONALITY. Titles such as Mr, Dr, Lord, PC, QC, or whatever are not asked for as they are not required. The
“Accused” is actually the LEGAL PERSONALITY which is the name on the birth certificate, so when they ask for
the person’s NAME, they are talking to the LEGAL PERSONALITY and not the human. This is because a human
cannot exist in the legal world - only pieces of paper can, and that is something which they are very careful not to
tell you.
 
This is a really key issue. Natural Law and Common Law are the only laws which apply to humans and they deal
only with harming other people or causing them loss, and outside of those restrictions, a human has free and
unlimited entitlement to do anything he chooses which complies with these principles. As opposed to this, Acts of
Parliament, “Statutes” and Statutory Instruments “Contracts” do not apply to the human but only to the piece of
paper which is the LEGAL PERSONALITY and which has no reality. As the legal fiction of the LEGAL
PERSONALITY was created by the company called “the United Kingdom Corporation”, it is that company which
gets to say what the rights and duties are for that piece of paper.

At this time, America does not have a government because “The UNITED STATES” is a commercial company.
The term “United States” means a Federal corporation. The US President is the President of a commercial
corporation and American citizens are, in effect, the employees of that Corporation. This present situation was
sneaked in by the covert actions of the Americans who organised and ran the civil war with the intention of taking
lands and assets from people who lived in the South. Most people imagine that, say, Virginia, is a part of the
American nation under the American government. However, this is not true as every one of the “States” is
actually set up as a commercial, for-profit, company, under the parent company “The United States of America”.
