Should I try upgrading it by adding a new power supply or graphics card? My desktop has 8 gb of ram installed already but it's making a weird loud noise whenever I boot it up but it only happens a couple times. I opened up the case and I discovered it was coming from the PSU. That is why I want to upgrade the power supply. My budget is $100 or less the power supply/graphics and some case fans if that fits in the budget. I'm having a friend come over to help me install the components.
