Certainly is. What is inside; hard drive(s), optical drive(s), RAM sticks, video card, audio card, etc.? What's the rated power of the power supply?
I bought a very nice used gaming computer, which i had used very much before. Shortly after purchase it started to slowly show signs of breaking. For instance, it would freeze, wouldnt turn on, combinations of the two, and then finally the entire hard drive was somehow "deleted" after being left off for 2 days. I have had the hard drive, and the mother board changed, and have had it checked for shorting issues. Until recently i came up with the idea that the Power Supply itself was too small, and the computer required too much energy. Is my idea plausible?
