My e machines T3985 has had some strange problems lately. At times the computer would get really loud, like a truck with high rpms(lower gear). Had to restart almost everytime it did this, then just the other day the computer will not turn on at all. No lights, no fans, nadda. After reading several posts about power supply problems, I tested my power supply on an old e machines comp. and it worked fine. I also replaced the power supply, still nothing. I don't want to be buying parts that don't fix the problem.
