Occasionally on boot my sata drive will slowly beep a number of times before it gets to the splash screen. It's definitely the hdd (the mobo doesn't have a speaker), and it's not the first one to do it on this PC. It passes SMART, and I've run a surface scan and an extended self test using hard drive sentinal. No issues. Any ideas?

Thanks. That is a different model, but PSU was my first thought. I haven't had issues with other hardware, but I know the PSU isn't top quality, to say the least. It is 7 years old now, and has worked fine. I've been suspecting the graphics card just pulls too many amps. Unfortunately, I can't swing a quality PSU right now. Fortunately, it's not my main PC.

I'll mark it solved if I don't hear any other opinions in the next day. Thanks again.
