• Loud startup noise
    13 replies, posted
A while ago my computer started making a reasonably loud whirring-type noise on startup. I built the computer myself and there are no performance issues with the machine and the whirring stops after a few minutes. I've tried removing each hard drive, I've made sure there are no wires interfering with the fans, and nothing seems to be visibly wrong. Computer spec: Intel i7 2.67 Ghz Quad Core 8MB L3 Cache Windows 7 Professional 3GB RAM (Can't remember the specifics) 9800GT 512MB VRAM 320 GB Seagate HDD 160 GB Seagate (I think) My case has three 40mm fans. Any additional info can be provided.
Same with my computer, but only 2 stock fans. I guess it's just to clear out any dust. Not that I would know...
I clean out my machine usually once a month so it's fairly dust free.
my Coolermaster Fan does this only its more of a clanky/whirling noise idk what the hell causes it.
Could be the PSU?
[QUOTE=1solidsnake2;20325105]Could be the PSU?[/QUOTE] Hmm, I guess it's possible. It's a Corsair 650W so it's not a cheap PSU.
couldn't it just be the dvd-rom drive? Is there still a cd/dvd in the drive when you boot it? Otherwise, check your Bios for standard Fan Speeds.

I've tried tinkering with my fan speeds but it makes no difference.
Your CPU fan usually spins up to 100 percent for a few seconds after powering up. Is this what you're experiencing?
[QUOTE=Zeke129;20332038]Your CPU fan usually spins up to 100 percent for a few seconds after powering up. Is this what you're experiencing?[/QUOTE] It lasts for much longer than a few seconds - more like a few minutes.
Open the case and start listening, only way to know for sure
Does it stop spinning at the same time every time?
[QUOTE=MrTilepy;20332187]It lasts for much longer than a few seconds - more like a few minutes.[/QUOTE] Alright, try unplugging your case fans one by one until you find the culprit. (Running for a short period of time with one less case fan isn't going to harm anything) I don't think you should do this while your PC is on though. Unplug, power on, listen, power off, repeat with another one.
[QUOTE=Wokkel;20332983]Open the case and start listening, only way to know for sure[/QUOTE] I've tried. It's very hard to determine where the noise is coming from. [QUOTE=Thor667;20333508]Does it stop spinning at the same time every time?[/QUOTE] Pretty much. The sounds also becomes slowly quieter (but still pretty loud) and then ends fairly abruptly and the machine runs at normal noise level after that.
