High pitched audio?

[Homeless]

I'm not sure what this is nor why it occurs, but I get a high pitched sound out of my speakers every time I run the scan for artifacts test on my card. I am running it on a stock radeon 4850 and the test does not produce any errors

I stumbled across this answer after receiving my new card vid card today and it did the sme stuff as the old one.

Apparently it's psu related, which means I'm somewhat screwed because I don't have funding to get another one
