HP problem

[zozond]

Hi guys, new to the forum here and thank you all for having me

Anyways! I have an HP Desktop computer

Specs: AMD Phenom II X6 1045T Processor @2.70GHz
8.00GB of RAM
Windows 7 64-bit
1 TB HDD
ATI RADEON HD 6450 w/ 512MB of dedicated memory
300W PSU

This is what i'm worried about, the PSU. Whenever I play "high-end" games like Mafia II and such (runs perfectly) i hear this high pitched noise coming from my desktop

im assuming its from my power unit becuase when i play minecraft that happens too, but whenever i put it in power saver mode the noise turns out

so what can I do?

i do not want to replace the PSU

P.S. the computer is running fine

it's prob the fan, and i'd say to replace the psu, i doubt your 6450 is even getting it's full power since i'm guessing that's the original psu which means it's a pos, ontop of the card recomending a min psu of 400w, you can replace it with a good one for 45 and have 10 or 15 in mail in rebates.

Replace the power supply before it takes out your computer. If its making a noise, its definately not a good sign.
