No post no beep no video

I recently purchased a new motherboard and processor because my old processor overheated. I installed CPU, memory, and video card and i get all the fans and lights on but no beep codes or POST when the system is running. There is no video, although the screen does flicker when i turn the power switch on. In short, all fans + lights on, no POST or beep codes. I RMA'd this motherboard because i thought it was the problem but am getting the same problem with the new motherboard Intel Core 2 Duo E6600 Conroe 2.4GHz LGA 775 MSI P6N SLI Platinum LGA 775 NVIDIA nForce 650i SLI ATX Intel Motherboard EVGA 256-P2-N615-TX GeForce 7600GT 256MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card 650 watt power supply

    I have a similar situation with my computer powering off after just a few seconds of start up. How would one know whether this is a bad CPU or a bad motherboard?

Could be a bad power supply or you could try this fix its really strange but it fixed my m8's pc The reset switch may be fried making the pc constantly reset itself just unplug ur reset switch and see if it works

Installing new motherboard, processor, mem, and video adapter. Powers on but no post.


If the beep is a very high pitched tone, turn off the computer. Your CPU is overheating. The thermal paste may not be spread correctly on the CPU or the heat sink isn't properly installed.

Otherwise, it's probably a memory error. This machine takes 2 GB of memory as 2 single GB memory sticks. Try booting the machine with only one DIMM installed. Try each stick individually before getting replacement memory.

I hope this helps.

Like to replace my processor which is AMD Duron 900MHz to Motherboard Gigabyte 7VM333M-RZ. Which current processors are compatible with this board? Please advise. I want a current fast processor.


Hi, As far as I can see, this motherboard is very old, and the faster processor you could get would be around 1.8 ghz, single core. Here's the list of supported processors:
http://www.cpu-upgrade.com/mb-Gigabyte/7VM333M-RZ.html
What I would suggest is that you buy a motherboard/cpu combo, then you could get a quad core with a recent motherboard for less than 150-200$. Of course you'd have to be willing to change your motherboard, but unfortunately, you're not gonna get a good processor with your current motherboard, and computer parts (like Ram, hard drives, video cards) are going to cost more and more for their rarety, while they are less performant.
Best of luck to you!

If new processor supports your old motherboard then you will upgrade system with your old motherboard.

If its not supported to new mother board then you have to buy new motherboard to upgrade your system.

Award BIOS Beep Codes
Award BIOS uses beeps of varying duration. A long beep will typically last for 2 seconds while a short beep will last only 1 second. Award BIOS also uses beeps of different frequency to indicate critical errors. If an Award BIOS detects that the CPU is overheating it may play a high pitched repeating beep while the computer is running.

I just bought a new motherboard; basically new everything, well on my old motherboard there was a CPU and on this newer better motherboard there is not a CPU. Do I need to got one? What is a CPU exactly?


first, make sure that the new mother board support the old Processors, ask the M.Board supplier about it (or google it) , and make sure you know the old processors type.If you wasn't really sure, just remove the old Processor from old M.Board, then check for the ID (such as Pentium 4, Pentium D, etc ) on top of the processor.

If the new M.Board support the Processors, then you can re use the old processors, if don't, then you don't have a choice, buy the new one that match with the new M.Board specifications.

Hope you understand.

I need to replace my Abit KV7-V motherboard what do you recommend?


If your going to replace or upgrade your motherboard, consider this following things:

1. Central Processing Unit(CPU) - Make sure that it can be use to the new motherboard or the motherboard supports your old cpu. If it is an Intel processor, get a motherboard that supports Intel processor or if AMD then get a motherboard that support AMD processors.

2. Memory Card - Make sure that it can also be usable to the new motherboard. If it is DDR then get a motherboard that supports DDR Memory Module or if it is DDR II then get a motheboard that supports it.

3. Video Card(if you have it aside from the onboard video device) - Make sure if you have a AGP Video card or PCI E video card it can be usable to the new motherboard.

Get a new motherboard that support all the stated hardware above.

Hope this could be valuable information for you..:-) Thanks..

Maybe a silly question to ask; but did you connect the processor power lead, as unlike some processors this needs a seperate supply.
