I'll like to use the question progressively: (I need to pin point exact issue) My system configuration is:
CPU: Intel i7 2600K 3.4GHz Quad core Motherboard: z68 RAM: GSkill 8GB saw-tooth 1.5V Graphics card: ATI Radeon HD6870 HDD 2TB SATA Power Supply: 750W (Antec Gold series)
I built this machine for gaming and nothing is under/over clocked, it runs awesome as long as it runs i.e.
Issue: While playing game computer would start making really loud scratching noises (doesn't matter what speaker level is at) and picture would distort and machine used to hang. So I replaced my video card and shifted RAMs from 2 different channels to single channel.
I've not seen scratching noise/ hang since then (maybe once/twice but not everytime).
However even now after playing for a while computer restarts by itself, why would it be?
Here are few scenarios I'm considering:
Overheating (Tried BIOS immediately after restart and CPU temperature was around 50-60 degree Celsius everytime so I'm not sure)
Use of SATA HDD -- really ?? can it be possible
Something entirely different.
I would like to pin point the reason first and then need to find an answer.
I've Windows7 installed and Ubuntu 11.10 issue is observed in both cases.
