PC wont boot. No beeping noise from MB. I have replaced the MB

post #1 of 17
Thread Starter 
After being in the cold for 3 months, my PC doesnt boost up. No beeping from the MB and nothing on the monitor
All my LED lights light up and fans are all spinning.
I have sent my MB for repair twice only to come back that its ok with no sign of changes.
What else should I look into??
Any suggestions would be appreciated.
thanks

Do you have a HDD or SSD? If you have a HDD try to listen and see if you can hear it being accessed. This will tell you if it is booting or not. Also make sure the motherboard is not getting shorted out on the case somewhere. If it is not it should be on stand offs to keep it from touching the case. Also make sure you have both the main motherboard connector and the CPU power connector plugged in.(Although I think it may beep on the CPU not being plugged in, can't remember) If you are using a dedicated video card and your motherboard has integrated graphics also try plugging straight into the motherboards integrated port.

Also correct me if I am wrong here guys but don't some motherboards have detachable speakers for giving the beep tones? You could unplug all of your RAM and turn it on and see if it beeps. If it doesn't beep that doesn't really help you, but it will give you some insight if it does beep.

Bummer...It doesn't beep even without the RAM sticks? Another thing you can try is put in a bootable DVD like a Windows disc or something and see if it sounds like it is reading that. You will need to blindly "press any key" for it to boot from it. Also you might try clearing the CMOS by removing the battery for a minute or so and then putting it back in.(In fact I would try this first)

Also I just found a guide that looks like it might be helpful. It has a lot of good diagnostic steps to cover.

It is also still possible that the PSU is faulty even though the computer is coming on. Unfortunately the only way to test this is manually with a multimeter or with a PSU tester.
