So I just recently did a few things:
I just got my dad's old 5870 and ran it in crossfire with my 5970. I notcie some slow down in my games and I thought my HDD was bogged down because it was like 75% so I also formatted and re installed my OS and cleared it out. Now when I try to run my games or even run twitch the system freezes and I have to do a hard restart.

I have all the updated drivers.

PSU: 800w
CPU: Intel Core I7 960
Video Card: 5970 + 5870 crossfire
Ram: 6 GB
 
Solution
That's a high quality PSU but typically 5 years is when they start to go down hill since the dielectric in the capacitors is generally worn out by then.

I'd look at replacing the HDD, and then the PSU when you can.
