hi. my computer wont boot. i had it stored in a room for a good 3 months. now that i have a network i wanted to add it in a new room. the first thing i noticed is that when i pluged in the ac power cord into the power supply, less than 3 seconds later the computer turned on, on its own. i didnt push the power switch. the power light on the tower is yellow instead of green, and it doesnt attempt to boot windows at all. it doesnt even show a picture on the monitor. i was wondering what would cause it to just turn on when i plug power into the power supply. and why the light just stays yellow? there no sign of beeping codes. the other light doesnt even flash. idk what light its called. it the one that always blinks when your comp is loading a program its a red light but it doesnt blink at all. the only light that goes on is the power light. which is yellow instead of green. any help is apreciated. thank you.
