Hello, I have a problem with this PC, I couldn't install Windows because it froze during installation. I checked Ram memory and bios battery, and it is OK. I wrote another dump in the main bios, but after that the computer wouldn't boot. The computer beeped 6 long times and 3 short times, and the red light blinked. I wrote the original bios that I saved earlier, but it still won't boot, and beeps 6 long times, and 3 short times. I'll forward the original dumps. Please help colleagues. Thanks.

пробуйте, если заведется, то обновите биос, он очень старый
