This is a memory failure problem.

Open the case and make sure the memory modules are seated in the sockets properly, make sure the computer is disconnected from the power source first.

Once checked plug it back in then switch on the pc.

It may bootup as normal, if it does not then you need to change the memory modules.

Memory upgrade on gx280 beeps on boot but doesn't start. memory beeps 1 234 5 6


When your computer emits beeps when you power on the computer, it's usually means that you have a memory issue. Try re-seating the memory modules and power on the computer. If you have more the one module, insert one at a time and power on the computer. The other issue is if that model supports 4 gig memory.

if you're familiar on how to open the computer tower's cover, we need to open it.
before opening the cover, make sure all cables are disconnected from the back of the computer. and make sure that you drained the remaining power of the system.
after opening the computer tower's cover, try to locate the cmos battery. (it's a silver coin like battery), remove it from your computer. wait atleast 10 minutes before placing it back. then try to turn on the computer again.


to open the cover, here's the link for the diagram:

Power on emachine T6420 and moniter is blank. The moniter soon loses contact with the computer. The fan run and power is OK there is no beep code.


If you mean after the computer performs the self test the screen goes blank and stays blank, eventually turning off you are having a hard drive problem. When the computer boots you should see an E-Machines logo and/or a self test on the screen. That is done by the motherboard as part of every boot up. After that the motherboard passes control to your boot device and loads your operating system. If your computer stops booting at that point, your boot device is not working properly. That could be caused by many things - virus, hardware failure, power outage. If you really mean you see nothing at all on the screen when you press the power button your computer simply is not working at all. Open the case, blow all the dust out of it and reseat all components you can, then try again.

Computer beeps and screen is blank


The computer beeps when some components are missing. Check all the connections.

Please try to press F8 at the boot, and choose Safe mode. You will see then if it is the hard drive the problem.

If you have more information after the T180 for the model number, can you indicate it please. You might have to update the BIOS.

HP Pavilion notebook Model No DV2224EA Product No RY395EA. On pressing the start button almost immediately there is a long beep followed by two short beeps. The computer than seems to stop functioning. ...


this doesnt mean that it's the motherboard, you could have other hardware probems that the beeps refer to depending on bios version, sometimes pressing F1 continues the boot, if so then the time and date should be checked, if wrong, then it's a cmos battery replacement thats needed, this beep can refer to also the graphics or the memory, so if you are able to locate the memory bay, remove and reseat the memory and try again

I have a presario compaq v3230AU lap top that does not boot.the power turns on but the screen remains blank.wat could be the problem.please advice


Hi there. It would help if you provided more info regarding your problem. The follwing would be good startpoints:

1. What was the last time you were able to do with the laptop?
2. Have you made changes [immediately] before the issue started happening?
3. How old is the PC?
4. What are its specifications (ie.CPU speed, memory type and size, OS, etc.)
5. Have you experienced this same problem before using the same computer, or on another computer?

Well, here's a shot in the dark. If the unit is, say more than 5 years old, it's probably a hardware defect. Meaning your unit's screen display data connection is already out of order. This usually happends to laptops with data connections too compactly embedded between the hinge of the laptop lid and chassis.
