Yesterday when I sat down by the computer everything was fine. When it was time to go to bed I turned it off as usual. This morning however nothing happened when I tried to turn it on. If I unplug it from the wall and then connect it again I have noticed that the fan starts spinning but only for half a second before it slows down and stops. If I press the start button once more nothing happens. If I unplug it and then reconnects it again the fan spinns for half a second just as before. What´s wrong?

I have a Amd 1.1 Ghz but I don't know what kind of motherboard I have. Power supply: L&C DR-A300ATX

Check your power supply first, any reputable comp shop will do this for free as long as you remove the unit from the computer and take it to them. If it is good I would suspect the CPU or mainboard after that. Start by removing all unneeded peripherals such as modem network card sound card cdrom and even the hard drive just leave the bare minimum vga card memory cpu and floppy. If it starts normally one of your other peripherals are causing it not to start. You can than narrow it down from there. If nothing happens after that than try reseating your memory and /or cpu, clear cmos etc. If this doesn't yield good results it comes down to cpu or motherboard.

I have exactly same kind of problem. The story beggins with my latest uppgrade. I changed motherboard, CPU+fan and RAM.
My motherboard: ASUS A7N266-VM (Nvidia)
CPU: AMD Duron 1,3GHz
RAM: Apacer 512 MB PC2100 CL2
OS: Win2K Proffesional
If I try to turn on my PC, it works sometimes, approximately in 50% of attempts. When it doesn't works I have to turn off the power on the main switch (on the rear panel of the case), wait 5-10 seconds and then I can try again. Power supply in my PC-case is ATX/300W and it worked fine before.
Please let me know if you have solved your problem, I will do the same if I figure out something.
Good luck!

Have you tried flashing the BIOS? I had this sort of problem on my new system. The mobo was rated for DDR333 RAM, which I used, but the system was unstable (constant reboots and freezes) until I flashed the bios. Seems there was a problem between the 333 RAM and my mobo, which the flashing fixed. Might be worth a shot, but you might want to read the FAQs at the site first.
Good luck!

Also, make sure that your memory is running at the same speed as the rest of the system. If I recall, the A7N266 allows you to increase the memory speed independant of the FSB/CPU clock.

It might not cause the problem described, but is commonly overlooked on boards that support the feature.
