Well my 5 year old pc decided to die just before the weekend, and in good old fashion style I groveled to the wifey for a new 1...wohoo she agreed.
Traveled the 140 mile round trip to Scan at the weekend and bought the following.
16gb ram
120gb ssd
3tb hd
gigabyte Z77x-D3H mobo
GTX570
and i7 cpu.
Oh and a new case, using psu from old system, 850w thermaltake.
No probs building system up, installed win 7 on SSD, put 3TB and 500GB HDD's in.
Strange thing keeps happening whereby I will leave pc to download some of my games etc, as my net is only 5mb speed so leaving it overnight, or for a few hours while popping out. But when I return I find the programes have stopped downloading and both internal mechanical HDD display autoplay play feature, its as though to pc has lost and rediscovered the HDD's. I have set power options to never put the pc to sleep, only the monitor to sleep, but this did not solve the problem.
I have gone into the advance power options now and set a time for HDD, will see later if that worked, but in the meantime any other ideas what might be causing this.
