every time i try to turn on my computer, i press the power button and an orange light blinks once, but the computer doesn't start. i tried opening the case while turning it on, and when i pressed the power button, all of the fans spun a little, and 2 very small red lights blink once on my GPU. today is the first day that my computer wont start at all after a bunch of tries, and usually my computer will start if i keep pushing the power button. any suggestions?

I had the same problem with my Dell Studio XPS 435MT. The LED on the power switch would glow amber while the PSU LED was green. However, it wouldn't boot. While the stock Delta PSU is rated at 360W, it degrades over time. Eventually it doesn't supply enough power to boot the system. I replaced the PSU with a 600W modular unit that has a big 135mm downward facing fan. Had to bend a tab down in the case for it to fit. Recommend using a PSU with modular cable system as it's tight in that little case.
