Re: MS 6340 - Hissing

sorry for double post, but could it be a torroid that is making this noise?

Re: MS 6340 - Hissing

Today I got the new power supply, and its not really made a difference. The system now runs fine without any disk drive attached to it, it stayed on a good 20-30 minutes in the BIOS. As soon as I try booting up with ANY disk drives attached at all, the thing gives up the ghost. The same hissing is apparant, and Im pretty sure its coming from the motherboard now. Somewhere north of the ziff socket. Could it be that a mosfet has failed???

Re: MS 6340 - Hissing

Thanks. I've just ordered a 300W power supply from ebuyer. Its only about £6-7, but the reviews seem good, and people are having no problems using it with systems of similar specs to mine. Hopefully it'll do the trick, considering the old supply was only 235W anyway.

Re: MS 6340 - Hissing

Just opened up the PSU and had a look inside to reveal at least 4 bad caps. Pretty much explains the irrational behaviour of the system, the hissing and the readings I was getting on the multi meter. Thanks anyway to you guys, the information on your homepage and forums has been of great help to me!

If a new power supply doesn't do the trick, I'll maybe be posting on here again!

First let me give you the specs of this system:

MS 6340 - Mini ATX motherboard
Athlon 1GHz TBird
384MB RAM
nVidia TNT2 RIVA 32MB
235W HIPRO power supply

Problems began a few months back whilst playing a fairly inensive game for the specs of this system - Day of defeat (Half life mod). The system suddenly rebooted, and since then has been unable to boot up without freezing for any more than 10 minutes.

I've stripped the system down to ram, cpu, and gfx and booted into bios and left it there to see if it freezes, and it does....
