A couple days ago, a beeping high pitch screech started coming from my computer. Originally, I thought it was the hard drive beginning to fail, but when I opened up the case, it doesn't sound like it's coming from the hard drive. But, I can't tell exactly where it is coming from. It almost sounds like it's coming from somewhere near the top of the mobo, almost by the PSU, but I'm not sure. Has anyone had similar experiences, or know of a probable component that is causing this? Also, it seems like it beeps more when I run more apps, such as folding@home. -------------

Hrmm, I've had fans give me weird sounds more then once, but your problem seems to be related to load. Are any of your fans automatically managed by applications or on your motherboard? If so, check them out and see if their screws are loose or if a wire is brushing them, they may be picking up under higher temps and causing that pitch. I have heard of phenomena with inductors 'singing" under load, its especially common on Nvidia 8800 cards and they do sing louder under load. Its not a sign of a problem usually though. Maybe if you can run your mobo outside of the case you can isolate the sound easier? ------------- Real Men play Tuba [IMG]http://img89.imageshack.us/img89/1859/newsmall6xz.jpg"> PH33R TEH 1337 Dwarf! http://www.tippmann.com/forum/wwf77a/log_off_user.asp" rel="nofollow - DONT CLICK ME!!1 |

| If it's a series of beeps, it will tell you whats wrong, just look up the error beeps for the device. |

After doing a little googling, I'm starting to think it's the PSU. If I shutdown and reboot, for the first 20-30 seconds of the boot, it's one long continuous high-pitch screech. After that it's just random and often beeps/screechs. It seemed as if the more stress I used on the computer, the more beeps/screechs. But then I tried playing a movie in WMP, and I didn't notice any difference in the amount of beeps/screeches than when I was just sitting at the desktop running nothing.

Unless your noticing instability I wouldn't be too worried. Like I said before, inductors can make high pitched squeals, and from the looks of it your PSU is being fairly well taxed. The other possibility is your cooling fan got loose in there, but as I'm sure you're aware, opening up a PSU is risky business if you don't know what you're doing. To be safe, you might want to check your rails with a digital multimeter and see if your getting stable power. ------------- Real Men play Tuba [IMG]http://img89.imageshack.us/img89/1859/newsmall6xz.jpg"> PH33R TEH 1337 Dwarf! http://www.tippmann.com/forum/wwf77a/log_off_user.asp" rel="nofollow - DONT CLICK ME!!1 |

So in other words, theres really nothing I could do? And you think 450W is cutting it close? I have a 300W PSU that came with the PC, but I replaced it with the 450W when I got the Radeon X1650 Pro. You think the 300W would be strong enough to run everything stable if the problem turns out to be my current PSU? Something needs to be done, and I don't think I can just let it go. The screech is so high pitch that you can hear it from the other room with the door closed. I started to feel a headache coming on after listening to it while I looked for where it was coming from. -------------

| A sound coming from the PSU/mobo area sounds like a fan to me. PSU's have one or more case fans to cool them, and from the mainboard, I'd suspect the CPU heatsink fan. |

Someone else on another forum suggested the same, and when I put my ear in the case, it does almost sound like it's coming from around the CPU. Why would the CPU fan be making this sound, and how would I fix it? -------------

| Maybe it's getting old, something in the fan has started rubbing or something. An easy test is to just open your case, and stop the cpu fan with your finger for a very short amount of time when you hear the noise. If the noise stops, you found it. |

Its very possible its a fan, so before you do anything with the PSU, check all the fans. See if you can remove the CPU from the case and make sure the sound isn't from the CPU or any fans in the case. If its coming from the CPU, check the fan and see whats up. If the inductors are making the noise, you can still run it while you wait for a replacement. If your worried about the PSU behavior, check the rails with a DMM. If the sound is really getting to you, you might be able to dampen it with a towel or something in the meantime. You might be able to run your computer off the old PSU, but if your overclocking at all, I'd drop your clocks to stock to play it safe. Good luck! ------------- Real Men play Tuba [IMG]http://img89.imageshack.us/img89/1859/newsmall6xz.jpg"> PH33R TEH 1337 Dwarf! http://www.tippmann.com/forum/wwf77a/log_off_user.asp" rel="nofollow - DONT CLICK ME!!1 |

Bearings wear out. The fans on CPU heatsinks are rather cheaply built, and wear out eventually. To find out for sure, open the case with the PC on, and just press your finger to the center of the fan (not near the blades, they will break easily) and stop the fan just for a second. If the noise stops too, then you've found the problem. The fix is replacing the fan. |
