Computer Freezing and Audio Looping From Low Hard Drive Space? Internet Problem? Please Help!

[lilant702]

I had computer problems in that my computer would freeze and my audio would loop very very fast, no matter what I was doing. I "got it fixed" but it still wasn't working after I installed my games again. I got it fixed by having the computer restored to factory settings. So I deleted ALOT of space and it hasn't froze once for about a month or two. I have 1tb of storage, a gtx 660, and a 550w power supply. My theory is that my power supply can barely handle what is in my computer, so the more space I put in my storage, the more power has to go into the power supply. Could that be a possibility?

My computer was pre-built so I do not know the exact parts. Most of them were made just for that PC.

UPDATE: I installed a bunch of games to get my computer passed 500GB left on hard drive space (Which is usually when it began freezing), and the day after, it froze. It did not do the audio loop/stutter but that was because there was no audio at the time, and right before it, my internet started lagging and I was about to disconnect from the game I was playing. Any ideas as to what it could be? I know someone that could help fix it, but I want to know from you guys. It could be a simple fix. Please help. Thanks.

Who makes the 550w , if it's decent it can easily run a 660.
