Newbie with just enough experience to be dangerous to computer needs help. Am running machine w/ nForce 680 sli Mobo, OCZ 700 watt PSU. Forget what type of memory i have. Worked beautifully for 1.5 years. Suddenly, I get back from Thanksgiving to find that the computer likes to randomly power-off itself.
Symptoms: None. No BSOD. No warning. Like someone pulled out the power plug (which didn't happen) or turn off the switch via power button. I can power it back on immediately and I might get 5 or 10 minutes of use before it powers off again. Sometimes while idle. Sometimes during intense use. And since I know folks will ask, have reset CPU to default settings, so overclocking shouldn't be issue.
Initially thought Vista problem (running 64 bit w/ SP1). But, it crashed on me as I was re-installing OS from Vista disk onto my reformatted C partition. So, I'm pretty sure it's a hardware issue.
What's the best way to tackle problem and diagnose the component(s) at fault? I'm 50% tempted to just build a new machine. But I really don't want to research all the new CPUs and mobos all over again just yet.
