Question about Computers & Internet

No beep codes no post 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

Hi, sounds like a RAM problem, if you have 2 RAM sticks, pull one out and put the second one in DIMM one, try that then try 1st one in DIMM 1, next test is to try a friends RAM. IF all fails go back to where you purchased the board and have them test it under warranty. Regards mistyman

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.

What is the beep code asus p5ntws


AMI (American Megatrends International) BIOS Beep Codes.
AMI BIOS uses beeps of the same length and pitch. The error is displayed as a number of beeps. For example, 4 beeps indicated a timer failure.
BEEP CODE MEANING POSSIBLE CAUSE
1 Beep (No video) Memory refresh failure Bad memory
2 Beeps Memory parity error Bad memory
3 Beeps Base 64K mem failure Bad memory
4 Beeps Timer not operational Bad motherboard

11 Beeps Cache memory bad Bad CPU or motherboard



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.
BEEP CODE MEANING POSSIBLE CAUSE
1 Long, 2 Short Video adapter failure Bad video adapter
Repeating (Endless loop) Memory error Bad memory or bad connection
1 Long, 3 Short Video adapter failure Bad video adapter or memory
High freq. beeps (while running) CPU is overheating CPU fan failure

If you placed the same processor in the new motherboard then it would appear that the problem is following the old processor.

One common mistake with p4 cpus is the 2nd power supply to the motherboard. Make sure you have plugged it in. Its a small connector that is only required for pentium 4.

If not the above, you could check the bios settings for processor clock speed to make sure that you're not overclocking by too much. Also check the heatsink/fan. A processor will fail very quickly with inadequate cooling. If everything seems ok but still getting 5 beeps, try a new cpu or memory.

EliteGroup GeForce 6100Sm-M Problem


4 things can cause this MB to do as you mention.
Bad CPU or the MB is not sensing the CPU fan and is protecting CPU from overheating.
Bad or inconpatible memory, If multiple sticks use only 1 at a time, This MB is known for having problems with both slots filled most of the time bios resaves can fix this but just set up with 1 first.
Reset the bios, Make sure the reset jumper is set back correctly.
Make sure it post without any extra harware hooked up first then add them.

The beeps are a old style of signaling the problem, You can find charts online that will tell you what the beeps mean long and short.
