I recently picked up a computer for a friend who said it wouldn't boot. Its an HP desktop with Windows XP its about 6 years old I believe. When I got it hooked it up it would turn on but would not boot to desktop. Long story short did a system restore and unhooked the computer. Like 2 weeks later I take it back to my friend HOOK everything up and I have a problem. No power to any usb ports, p2 connectors, and no power to the monitor. The light on the monitor will turn green when you turn the computer on and then the light will turn YELLOW like the computer was on standby. The only device that im getting to work is the dvd drive it will OPEN and close. So i don't know if the system is booting up or not. The computer will turn on and the fan on the mother board will turn on. Well it's easier to swap in a known good PS than CHANGE the motherboard......if the PS is 6 years old than it's seen it's BEST days.
Any beeps at startup?...reseat your ram, video card.....any bulging or leaking capacitors....they're the ones with the + on top......unfortunately the symptoms can also point to MB failure....by any chance would you be able to tell me how do you reset your ram? Patolndlx3,
