My computer this morning has started having a problem I thought I had corrected and wanted to confer with you guys and hopefully find the solution before any major problems (and damage) occur to my PC. The issue is this, I go to bed last night the computer is running beautifully, Then the next morning out of nowhere I go to turn on the computer, the lights in my case turn on, case fans, and CPU fan start spinning, then it shuts off for a couple seconds, and repeats. I cannot stop the loop short of turning off the PSU. I didnt have enough time to do a lot of trouble shooting before work but I did unplug a few things, my speakers, my external HD and my Game Pad. Then had to go to work. I get home from work and decide to take a chance, with all those unplugged and turn on the computer. It booted as normal.
Now the thing is, about 9 months ago I had this exact problem before and thought I had determined it was the PSU starting to weaken, so I pulled 2 of my 3 GPUs from the system since for my needs it was more of a gloating factor then an actual need for super HD capabilities. It ran find after that till this morning, where it started happening again. The thing I hope to get some help with is, is this the way a computer normally reacts when a PSU is about to bite the dust? is there other trouble shooting I can do to help determine the most likely cause? I hope to do this without causing any extra stress on the components as replacing something like the CPU if it took to much strain from an under performing PSU would be very difficult for me at this time. I could afford a new PSU but Im not sure about replacing my I7 Processor right now, since that's like 3x more cash lol.
