Please help. A couple of weeks ago when I would start my computer, the front panel light and fans would run, but I couldn’t get any video signal. To get the computer started, I needed to press and hold the power switch a couple of times to get the video to display. After 3 or 4 tries, the computer would receive the signal and would start-up. I would hear 2 beeps and see a warning message telling me that “overclocking failed”, although I am not overclocking my system. I went into the setup menu and checked all of the settings, which seemed to be in order. One morning after holding down the power button to reset the system, I smelled something burning within the case, but I didn’t see any smoke. I visually inspected the CPU, Motherboard, video card, and wires, but couldn’t see any evidence of something getting fried.
Now I am having the following problem—when the power button is pressed, there is no display, fans are not spinning, and the power light on front panel lights up for a fraction of a second and then goes out. The system retains the state of not being powered on, although the green standby LED light on my motherboard does light up. Both the 20-pin and the 4-pin ATX connectors are attached to the motherboard. I thought the power supply was the problem, so I replaced it with a new one, but I am having the same problem. The front panel light and fans will run without any video display if I attach the 20-pin connector and not the 4-pin connector, so the power button on the case does not appear to be the problem. Any troubleshooting help would be greatly appreciated.
Here are my system details:
MB: Asus P4C800-E Deluxe
CPU: Intel Pentium 4 2.8Ghz 800FSB with Hyper-Threading enabled
VGA: BFG Technologies Asylum GeForce FX 5700 Ultra 128 MB AGP
RAM: 1 GB
HDD: Maxtor 120GB
DVD-RW: Plextor 16X; Lite-on 4X
PWR: Ultra X-Connect 500W ATX
