Motherboard problems no boot but sartup all fan and no video

could it be booting, is the keyboard lighting up? if so, it is likely a video card problem.

Sounds to me like it might be a problem with the motherboard or CPU. Try a different CPU cause if the CPU can't stay powered up then that will cause the fans to turn on and off. Also make sure you only have power going to the motherboard so that will eliminate any hardware devices like a hard drive, or dvd drive causing problems. Try different memory as well to make sure bad memory isn't causing the system to short out the fans. You only want the bare basics hooked up so you can have the best chance of getting video. If after you go thru these steps you still don't get any video then that means the motherboard is faulty.

Can you see some indication if the CPU is booting up. Or fan is running?

Unplugged the unit and powered down. Isolate the problem. Check first its RAM,video card,some other PCI card. reseat one by one until the system boots up.

this is a clarification request as well as a possible solution... are you using the onboard video, or a video card via pci, agp? because if you are using a new video card or a new motherboard you may have to use the onboard video temporarily to boot up and install drivers for the motherboard, then plug in the video card and it should boot up so you can install the drivers for it.... sometimes this is not the case though, i have had to trick a computer into doing this before which is not a smart idea at all...

who have a solution for this problem of my asus a8s-x not boot up, not beep, not message, have connect the memory, cpu, fan , video card, keyborad, this is new, only the fan work.

Thanks

Hi this is tech crazy

The solution to the problem is as follows

The main reason for CPU fan overworking or not working is due to the load we put on the syatem while operating.So,the first reason for fan not working may be due to the SMPS malfunctionality.Better check out for it.The reason if fan is working but Overworking is due to viruses is system.So go in for format

Hope this solution helps you

Please do rate me on the above said solution

Try to unplug unnecessary hardware.. just plug in the monitor to video card, power, and the memory.. unplug the IDE cable or SATA and also the USB devices... Observe if your system will boot. sometimes hardware damages prevent your system to boot..

could be a cpu, memory, or motherboard problem.

check your start up files what gets preloaded get software like reg cure it will show what is been loaded on sartup

sounds like the motherboard died.
