PC becomes frozen and forces a restart, displaying a black screen.
Pc froze unexpectedly after changing network adapter settings. I forced shutdown by repeatedly pressing the power button. When I tried to turn it back on, there was no display, though the CPU fan was running. I've tried several steps so far: removed CMOS battery, unplugged RAM, disconnected all peripherals, and checked another PC with the same components working. Could you help identify the problem? Thanks.
JBAT1 appears to be your Clear CMOS pins. Did you connect them using a tool like a screwdriver or paperclip? This should reset your BIOS back to its default settings, and you should likely reach your BIOS menu. I usually began by just shorting JBAT1, and if needed, also removed the battery.
When BIOS isn't reachable, the issue likely lies with the system's connection or your graphics card. Turning off a network card shouldn't affect whether it boots into Windows. You'd just lose internet access. Have you tried a different display cable? Are there alternative ports on your motherboard to test? Could using a separate GPU reveal output? Is there another monitor available for testing? If none of these steps help and you've already checked the power supply, the main problem probably involves a faulty CPU or motherboard—hard to pinpoint without replacement parts.
Thank you for your response. I apologize for the delayed reply. I purchased this PC from a repair shop, which found the motherboard to be defective. They then swapped it out with a replacement part.
