At start you 3 beeps and fans come on and nothing else

try another memory and if no success the motherboard will need to be reworked

I'm going to take a stab and assume the laptop is beeping after you start it up... if it is this is called a beep code, its telling you something is wrong with it or something has changed. F2 or F3 will probably take you into its BIOS or give you access to the boot order. When I used to upgrade memory in dell latitudes it would beep on boot and say something to the effect of 'amount of system memory has changed, press F1 to continue or F2 for bios'. If you made changes to the laptop's physical components it is basically telling you something has changed and wants you to go into its BIOS to confirm. If you have done nothing to do and its beeping on boot, then its telling you there's something wrong. You will be to determine the make and model of the laptop and then obtain its service manual to look up what the beep codes indicate... there are sort of like morse code, 2 beeps means this, 3 beeps means that etc. What is the make and model and did you do anything to do (i.e. upgrade memory) before this started happening?

first remove the cover of your computer after switching off the system and removing the power plug the power the system and see whether the processor fan is working if not power off the system and remove the 24 pin connector from the smps to the motherboard and short the green and black pin of the conector from the smps and see the smps fan is working if not replace the smps if working then remove the memory from the slot and clean them or change the memory to which match the dimm slot an connect the connector and switch on the computer

Hello
No beep?
1 Start with making sure all conections are correct,hard drive,dvd,cd,floppy.
2 Check that processor is mounted correctly,remove and do over.
3 Also processor fan.And heatsink.
4 Memory sticks,remove and put back in firmly and secure.If you have 4 memory slots and 2 memory sticks,seperate them.Most slots are color coded white blue white blue or whatever color you may have.So if you have 2 memory sticks put one in white slot,and the other in next white slot.

Im betting you have either processor in wrong or memory in wrong.

More than likely, a memory chip that is not seated properly. Open the computer case and look at the motherboard. Memory chip slot banks are usually about 2 to 3 inches long, with white clips on each end of the individual slots. Check for a loose one. They must be seated VERY firmly so that the white clips lock down.

there is problem with the RAM of your Computer. please check it with replacing the RAMs. hopefully it will work fine.

Lack of video signal is usually 1 of 3 things, Power supply (PSU), Video card or Motherboard (mobo).
Situation #1: If you get a blank screen and no sounds or movement it either indicates that the power supply unit (PSU) has failed or something on the motherboard has failed, preventing normal startup.
Situation #1A: You might get some power lights coming on and some fans spinning but the video output does not happen, usually indicates that motherboard or PSU is going out or has gone out. Occasionally it will be due to a weak (damaged) PSU.
Situation #2: If you get sounds (normal Windows startup sounds) and lights but nothing on the screen then it indicates a failed or loose video card.
Always try a different power outlet that you know is working. (Eliminate the easy stuff first!)
If it is out of warranty, try opening up the case, with the power off, of course. If you have Sit #2 and have a video card that you can reseat (take out and then put back in) try that. If it is onboard video then you may have to buy a video card for it.
Also take this time to inspect the capacitors on the motherboard (they look like tiny soda cans) and check for tops that are bulging, swelling or leaking anything. Capacitors should be perfectly flat on top. If you find these then your motherboard is bad (well technically the capacitors on your motherboard are bad). The bad caps will need replacing to fix (not a job for an amateur). If it passes the visual inspection then it may just be your power supply is bad. Notice that a bad PSU does not mean you are getting no power, just not enough to start and run the computer.
A few years ago a company stole the recipe for making capacitors and started making their own capacitors at really cheap prices. The stolen "recipe" was not complete and not correct so these caps started failing after about 2-3 years of use. Emachines, DELL and Gateway were the computer companies most affected by the bad capacitor issues, although any of the big companies could have the same problem. These bad caps also affected power supply makers.
Do you hear anything else during startup, beeps, fans or drives spinning, lights on the front or back of computer flashing or lit up? Do you hear the Windows starting sound?
Let us know more then we can troubleshoot better. Do you have the 4 diagnostic (A,B,C,D) on the rear of the machine? What is the front power light on the CPU doing?

same here! ASrock sucks!!!! How sad!

The three beeps shows the Memory Module Test and that symbolise that the memory module is having a problem and to my knowledge when there is a problem with the memory then you have to open the casing and remove the memory module and clean the slot very well and if slot in back and the memory do the same change the to the second memory slot if it happens there again then you change the Memory module.
ok
rate this solution.

I had same problem!
I figured there was something wrong with my memory because that is what the manual says the constant beeps mean.
I bought a new PNY memory stick 1 gb DDR and got the same beeps when i put it in.
So being totally disappointed I tried putting the Stick in the #3 DIMM. I booted up and IT WORKED!
I have not called tech support or tried both 1 & 3 DIMM together but I will try after I set up the rest of my computer.
