CoolMax has loud ringing?

post #1 of 7
Thread Starter 
Hey, earlier this year (January to be exact) my mom purchased a new PC. It's a Compaq Desktop, specs are: X2 4200+, 2GB RAM, 360GB HD, 6150SE IGP, and a Dual-Layer DVD-RW Drive. My problem is, when she first got the computer she was experiencing lockups, you could click on relaod in IE and the PC would lockup for about 3min. One time my sister was typing a paper on MS Word and it was an extremely important paper (Had to do with her job) and the friggin PC locked up completely! We had to restart it and she lost her whole paper which she spent more than 2 hours on!

I asked about this problem a while back and they (OC Forums) told me it was most likely the PSU, so I replaced the PSU with a 400W CoolMax

Click Here for PSU

I originally had this PSU when I was going to rebuilt my old 3800+ system but I gave up. Now that I put this PSU in here, it should be more than enough to handle the things in this PC! But whenever I turn the PC on I hear this very loud ringing, the same noise I heard from my old PC when the MB was dead! Funny thing is, the ringing stops about 5 seconds later and during the ringing the motherboard is still going through booting and everything. I'm not sure what's the problem but I'm concerned because if my mom continues to hear this she's going to blame everything on me and bottom line I want to know why Compaq didn't put a quality PSU in there system!

Does anyone have any idea as to what could be causing this ringing? Strain on the rails?

P.S. I'm going to school so I most likely won't read any of the responses until I get home.

I wish you could be more specific on the noise, you say ringing do you mean like squealing? Like a high pitched squeal? So it starts to boot and then just stops? Are you sure you got all of the power connectors to the motherboard?

could be undervolt alarm of some kind on the mobo, could be psu squeal/induction coil whine, or soemthing else - hard to say without hearing it. You should open the case and power up the pc and try to determine exactly where its coming from, that would be the first step. Also I would recommend telling your sister that she should save important documents more than zero times in a two hour period, thats just common sense, even on a pc that has "no chance" of crashing.

Can't say I can think of what a "ringing" noise would be. Maybe a high pitched "squeal"?

If that's the case, it's probably what the guys above said and is either transformer or coil whine. Harmless, but annoying. If you're lucky it's just the +5VSB transformer. Easy to troubleshoot: You just unplug all of your USB stuff and see if the noise goes away. If it does, get a self-powered USB hub.

Yeah, it's a high pitched squal and it lasts for about 4 seconds then it goes away.

ah, its most likely coming from the video card or the psu, and is most likely coil whine. As long as it goes away it shouldnt be an actual problem. Annoying? yes. Problem or impending doom? not usually

Ok thanks, it's 100% coming from the Coils then because the PC has IGP. +Rep to those who helped
