Over working the PSU?

  Ade_1 18:05 03 Jun 2007


Today I purchased a new sound card as my current onboard ones are playing up.

I inserted the card, installed the software and as a result of that my comptuer started to run unbelievably slowly.

Once I had restarted it (after being instructed to by the installation wizard) I was getting the cursor in the middle of the screen and a black background, nothing else. Nothing happened for about 5 minutes so I turned it off.

I assumed that I was over working the PSU as after I took out the sound card the computer started working fine.

I currently have a 305W power supply.
Components include an X800 PCI-E
P4 Processor
Network Card
A few USB Peripherals.

I tested in on XP, I didn't get round to testing it on Ubuntu, I assumed that it would be the same.

So, I was wondering, was the reason why my comptuer seriously struggled on booting because I was putting too much strain on the power supply?

Thanks in advance

did you disable the onboard sound in the bios before installing the card.

I inserted the card into its PCI slot, then turned the computer on and then disabled the onboard sound before the computer booted.

you should have disabled the onboard then shutdown pc, installed card, restarted and installed the new cards driver by way of the new hardware found wizard.
a 300 psu is not very much and you would be better off with a 450 or 500 with a 80% + efficiency rating.

I will have to give that a go later then.

Yeah I have often wondered about a new PSU, but seeing as though it is a Dell one I don't think that a standard power supply would fit.

Thanks for the help.

A sound card requires a handful of watts.

See, for instance:

you should turn off after fitting the card, then restart for it to clear any windows tasks that do not get shut down with just a restart
