The system is unable to access BIOS functionality.
The system is unable to access BIOS functionality.
Hello everyone! Could you assist me with my computer? It’s not working properly right now—I can’t boot up BIOS or see anything on the screen. The issue began a few months ago. Every time I power on the PC, the GPU fan makes a loud noise, especially when I push it to maximum speed. At first it spins fast, then it slows down and stops, after which the startup screen appears with all the text, letting me use the computer normally. I know something might be wrong, but I’m ignoring it since it works fine now. Recently, I cleaned the PC using a paintbrush (lol), and after reconnecting everything and turning it on, the fan noise and speed didn’t disappear immediately. It just ran for a few minutes before restarting again. I don’t know how long this will last. After a short while, I turned it off and restarted it, but the same problem returned. In the past, I faced the same issue and took my PC to a shop—they said the motherboard is damaged because of frequent power surges at home. We replaced it. Maybe this is the same reason here. But this time, I suspect it’s not the motherboard. My guess is it could be the CPU, RAM, GPU, or even the power supply. I noticed the SSD light wasn’t showing properly this time, which suggests the system can’t start programs at all. This makes me think my CPU might be the problem, but I’m just feeling it. With all this info, I’d really appreciate any advice or clues about what’s damaged. Note: I already bought an upgrade (too late), and if only the closest shop was closer—45 minutes away would be great). Dang it!
Welcome to the discussion boards! Be careful, this might have led to hardware issues. Unlikely, but still a chance. Particularly if the brush uses synthetic fibers. In the future, consider using compressed air instead. Let the machine run for about 15 minutes. It could be trying to reset settings or perform memory training. This shouldn't cause any damage. A UPS might help shield your components from this kind of stress. Nice effort in finding a solution! Good thinking. I think it's unlikely the CPU is involved (unless it's a recent or older Intel model or possibly the AMD 9800x3D, though that's still under investigation). I'd lean toward the power supply unit, but you mention it's at least turning on. This doesn't rule out a mostly failed PSU, but it should give us some clues about what's wrong. It could also be the GPU or RAM—these parts are usually the most sensitive. My main guess for broken hardware is another faulty board. Something important to check is whether the motherboard provides debug information. Do you have any beep codes, diagnostic codes, or LED indicators accessible? Refer to the motherboard manual. As leclod mentioned, specifications can be useful. Lastly, this issue began when you touched the inside of the PC. That’s a solid move—disassemble the tower completely and rebuild it with just essential parts in a cardboard box to test if it starts working. Also, a simple question: can you connect the monitor using the same port and cable with another device? All those power fluctuations might have caused damage rather than just affecting the PC.
