hey im working on an acer desktop...the first time i plugged it in..the ram proved faulty, so i cleaned them and the slots with electronic spray. it worked fine after that...booted it a couple times, no probs. recently it started taking really long to boot. now it isnt booting at all. when i plug in the power supply, it turns on without me pressing the power button, the cpu fan starts spinning, and the HDD led stays on (no power led)...i had problem like this before but i cant remember what the fault was....Its a fairly brand new machine.
