If the cpu/heatsink fan isn't turning then most pc's will shut down to avoid further damage to cpu & board. I would first replace the fan if it's the one over your cpu. Try replacing power supply. If your board has the 4 pin plug, you must have that plugged in. But keep in mind if that fan isn't running a new power supply isn't going to make it start working. You have to have that fan working. Then go from there. If once it is working & other devices like video and/or roms aren't, check your memory. The best way to troubleshoot devices are to plug one at a time in and power up until the problem starts. Hopefully you won't have to go to that step.

I have the very same problem, the Drive light turns red, the screen is "black" and the battery charging light indicator on the front is off. No differance if I'm traying to power up on battery or AC-adapter.
Before this problem appeared I had problems where the laptop was powering off, with no warning, and I had to restart it. This happened several times and was going on for about a week before it died totally. Can it be the CMOS battery on the mother board? Anyone having clue what the problem could be?
I want you to try first swap the power supply box of the PC if no change ? go to the CPU socket remove the CPU check if any component is burnt that area if ok put a new CPU then on it . If still behaving the same ,then the mother board is bad get a new mother board
Do the following to check motherboard.
1. Take out all cards from motherboard except video card. Unplug ribbons to CD-Roms, hard drives and floppy drives.
2. The only thing plugged into your motherboard should be video, keyboard and ram.
3. Check once again that all the power connectors from the power supply are properly plugged in. There may be two or three of them depending on the type of motherboard. Try turning on system. If you get no response then try next option.
4. Find the wire coming from your power on button and trace it to the motherboard. Pull the wire off and use a screwdrive to short between the two posts. If the power button is bad this should start the computer. If not your motherboard is probably toast.
I understand that your cpu is not turning on and the repairer confirmed that it is the issue with the mother board. I suggest you to please check the smps fan spinning or not. If its spinning then then the issue could be with the mother board. If not try changing the power cables.
Next check whether your cd rom light is glowing. Even if there is an issue with the mother board, as the power is supplied by the smps the light should glow if the light is not glowing its clear that something must be wrong with smps.
Please provide us the result of the above steps so that I could assist you further.
