A few months ago I built a new desktop using a barebones kit from TigerDirect. The specs are listed below.
It's been running perfectly since I fixed my previous issue.
A few hours ago, I was trying to compile the Linux kernel. The computer started making a very loud buzzing noise that sounded like the PC speaker. I tried everything I could to silence it in software, but it didn't work. No matter what I did, I would hear the buzzing noise on and off whenever I tried to compile the Linux kernel. I've compiled the kernel twice before on that computer, so I don't know why it was only doing it now. (I know that it isn't an issue with high CPU or disk usage, because I tried several other intensive things and nothing set it off. However, I do think it was a hardware issue.)
Other than issue, everything worked fine. I restarted the computer several times and it worked fine. However, the buzzing still persisted, so I decided to simply remove the PC speaker. I opened up the case, pulled out the speaker, and closed the case. Then I turned the computer on. The PSU fan started spinning, but the processor and case fans didn't, and the nothing showed up on the screen (so I don't think the processor was running at all).
I brought the computer down to the desk where I work on it, and tried running it again. This time, everything worked! So I brought it back and plugged it in again, but it still didn't work. However, I noticed that it was properly powering USB devices.
I brought it back down and opened it up again. I tried putting the speaker back in, but that didn't fix anything. Now, nothing at happens when I push the power button. However, whenever it is plugged in, the hard disk activity LED blinks periodically. I also hear a clicking noise when that LED turns on.
I'm guessing that it's a PSU issue, but I don't really know. Also, any guesses as to why I heard the buzzing would be helpful (though not nearly as important; I can live with buzzing).
The specs for this computer are:
- Gigabyte GA-H55M-S2H motherboard
- Core i3 530 CPU
- 4 GB DDR3 RAM
- 1 TB SATA hard drive
- 500 Watt PSU
