new PSU...Now a Noisy Monitor...

Dave Gregson
I have a PB 1508/n. Just recently bought 4gig of ram , installed that no probs... Got myself a PCIe Nvidia card 7000 series. And everything runs ok.

After reading the instructions for the graphics card it said that the PSU should be at least 300watts. So with this in mind i got a new PSU...

Installed that which wasn't too bad.. Had to remove 2 stcks of ram to get the cable for the board in nicely, but then replaced them.

Now this is where all my troule begins..... :cry:

It seams that when the CPU is running at 100% there is a loud noise coming from the monitor, (A Constant high pitched tone) Even with the sound cable UNPLUGGED the noise is coming out of the speakers on the monitor. When the CPU drops to 99% or lower the noise stops.

As you can image when the computer is turned on the noise is on for a while until the computer settles down.

This will be the second power suplly that i've tried... What could be causing this? :?:

Any help would be nice... Cheers Dave :)

    Google doesn't know what a PB 1508/n is either!

    Apart from the TWO entries for TechRepublic and ExtremeTech - BOTH posted by you.

    So what is a PB 1508/n ?

    Packard Bell system (PB) but I could not find any reference for the 1508 or 1508n on their site. However, there is a user group that takes support questions from them

    I spotted a reference a couple of days ago:

    It appears to be an iMage model of a Media Centre chassis

    He probably got embarrassed and didn't want to use 'Packard Bell' on a public forum.

    Mind you, all joking aside, I reckon he's pushed this particular 'puter a bit TOO FAR, based on the spec I saw. That would explain the monitor noise.

    But if he won't respond to any questions AND continues to cut&paste the same question, how the **** does he expect to get an answer?

    Everybody has to start from somewhere..right?
    Sorry i did'nt answer but i never got an email to say i had a response. (Forgot to tick notify) Trust me.. i would have answered almost straight away.. I also had to contact TR as my account didn't validate.. I saw my post when i first signed up then it was gone.. I am thinking of upgrading the motherboard soon but just wanted something a bit better to fall back on if i made a co*kup of building one. If there is any more info that you require of me i will check back everyday, twice a day if need be...
    Thanks guys

    Hey

    From what I have been reading, I don't think this has anything to do with the PSU at all, to me all this sounds like is interfernce coming in from the speakers. What time of Monitor do you have connected to this system. Also did you try and hook up another monitor and different speakers, to see if you were getting the same problem?? Many its a bad monitor or speakers. Now all the same you should be running a PSU higher than 250 anyways, you want at least a 400 with what you are running and to be on the safe side. Don't want all your nice new parts to slowly fry do to a cheap PSU. But really i think this is more of an issue with the monitor or speakers, not the system its self. The monitor is not even really running off the psu and we know the speakers aren't this isn't the old AT days haha.

    Thanks Rick

    I agree that it's probably not the PSU at fault, that it's something else causing interferance. I also agree that the PSU is too small for what he's got.

    Could be though, that it's something as simple as the proximity of the computer to the monitor. They're SUPPOSED to be separated by what? A couple of feet minimum? Heck, we have Police vehicles driving by the building that cause interferance with the computer closest to the street. As they pass, a loud squeal comes from a particular brand of speakers. Different brands don't do it. So, frankly, if it were me, I would try different speakers AFTER the correct size PSU has been installed and see if that solved the problem.

    You have a high pitched sound coming from the monitor speakers during boot up while the CPU is running at 100% and continues until the computer settles down. You recently put in a new graphics card which stated in the instructions that you needed a 300watt PSU, so you put a new one in, twice.

    Your specs are:

    PackardBell 1508
    4gb sdram DDR400
    Sunshine Motherboard made by Gigabyte (GA-8I915PM) 915 Chipset, Bios 2.0u

    Philips 190X5
    Windows Ultimate (32bit)
    250watt PSU
    No modem (Just wireless Netgear Adapter) USB))

    The first thing I see is that, according to what you've said, the graphics card requires a 300watt PSU but you only have a 250watt PSU in the system.

    Is it possible something isn't getting the power that it requires while the processor is drawing max power after bootup?

    I installed a 650watt PSU which resulted in a tone coming out of the monitor speakers. Thought it was the PSU so i changed the PSU for a decent PSU Artic Cooling 500Watt. the problem still persists. I've tried moving the cables within the computer in case of interference, but nothing. I've removed 3gb of ram that had no effect. So i ended up putting my 250watt PSU back in.

    The only think that is different on the PSU's is a white wire. On on my oringinal there is a blank on the pin oppisite the gray. On the new PSU there is a white. I've had a look though the bios.... well not my cup of tea i'm afraid... Could not see anything that stood out...

    or monitor? It may be that a component is sending out a frequency that is interfering.

    Another thought would be to try a different monitor, or to see if this monitor does it on another system as well.

    Will have to try and get a monitor from somewhere as i don't have a spare, will also try a different graphics card. Do you think it could be caused by the extra white wire on the PSU? Could be that my MB doesn't like it? Dave.
