LOSTrustEY

So recently had my steam account hacked. It was from a trade in the community hub. I got a little box on my steam that said I have been signed out and I needed to put my password in. I put my password in and it said incorrect.. I later logged into one of my alt account to find that the account that was hacked was online. playing CS:GO. I have lost mainly all of my CS:GO accounts and I need help to know how to recover it. I have sent a recovery email to steam but it has been nearly 1 week without a response. Please could someone direct me on what I should do. This is the account: https://steamcommunity.com/profiles/76561198454345754/ Thank you.

CPU: AMD Ryzen 7 2700x GPU: AMD Radeon RX 5700XT 50th anniversary edition I need help knowing how to fix the blue screens all all of the crashing, if you know anything about what is happening please message me and tell me what I can do to fix this problem.
