Dead laptop, please help

Hi.. please excuse my english. First, I have this laptop, but it's not "touch." I'm sure it's the same model.. and that's not the problem..

My problem is that I bought it used, and then I installed a Windows 11 "clean installation." I did that hundreds of times before. Actually, software things are my hobbies, so I'm sure that Windows installation is done correctly.

After a week of normal to hard using (gaming, multi-tasking, etc...) Suddenly, it freezes while I'm working on something, I pressed the power button for a couple of seconds and then tried to start it again, It started and worked perfectly fine.. after one day, it crashed again, I did the same thing, but it kept crashing after less than five minutes from the start.

I left it for a day and then tried again.. this time, it crashed on Windows booting step and kept doing that several times.

I thought if I reinstalled new Windows, it would be fixed, but when I prepared my booting device and opened the bios setup, I recognized that the pc info (device name, model, ...) are showing "invalid".. well, that's wired cos they appeared correctly the last time I installed windows when I just bought the laptop.

I ignored that "Invalid" thing and prepared the laptop for the windows installation, and then restart it with pressing F12 to display the boot menu but it showed up in a very very slow animation, I didn't like that so I shut it down and started again but this time its dead.. there is a power indication and start indication but no screen at all, not even a blink.

Please Help.. (thanks)
