1.	Solve : Computer problem. thought it might be power supply?
Answer» so i thought the problem with my system was the power SUPPLY. i BOUGHT a new one, changed it out and when i turned on the system all the lights were on, but it seemed like it wasn't really working. they just continually stayed on. it didn't seem like it was booting up either. nothing WOULD come out on the screen and it acted as if it wasn't doing anything. can anyone help me figure out what might be wrong with it or how to test different parts of my system to figure out what it is i need to replace. thanks for any help.What problems did you have before? What is the computer or MOTHERBOARD make/model? What make and wattage of power supply did you put in? Was it new? The first suspect is a BAD install. The second is other damaged components. The third is improperly seated components. Strip it down to CPU/Fan, 1 stick RAM and video card ONLY and see if that starts after you recheck the power supply connectors.
