No power on N1996 argon motherboard. Cpu fans

No power on N1996 argon motherboard. CPU and case fans turn on then go back off. The switch on the front is yellow then blue. I have tried a new power supply. Is there any way to troubleshoot motherboard without replacing it?

If it's switching its self off after about 10 second then Your CPU Chip is not right some how it could be / damaged / the wrong socket type for the board as alot of CPU's are very simmler / The CPU's (4 pin) power supply is not connected or the CPU hasent gone in to the socket properly when this happens it will power up but will send no power to the monitor, or somtimes set off an alarm that sounds like a sciron going off.

When I turn on the power, the fans start to turn but then quit after a couple seconds.


hi,

i,d suggest CPU/Memory or motherboard Fault.
try removing 1 stick of memory, then re-boot. ( if theres 2 In )
remove the cpu fan, Check for Dust Blockage, remove CPU. And re-seat-seal-replace Fan. ( re-boot )
remove power from Case ( mains power ) remove side panel, locate CMOS Battery ( Silver coin-Cell ) On motherboard for 10 Seconds, then replace, repower and boot up.

Any of these could resolve your problems.

CPU NOT DETECTING ERROR CODE FF


If you are having trouble booting the system and getting a screen try the following multi-step procedure. Power off your system first before completing any of the following tips.
1) Check CMOS clear jumper JP1 (JBAT1 on some systems). Set for CLEAR for 5 seconds, then move back.
2) Check CPU host clock jumpers (if any) are properly set. Note: does not control memory bus.
3) Check your power supply. Should be 110/115v for North America.
4) Unplug all data cables for IDE and FDD from the motherboard.
5) Unplug all power supply cables attaching to your IDE and FDD drives.
6) Remove all cards and devices EXCEPT for video, RAM, CPU, CPU heatsink/FAN.
7) Move memory into a different bank, if available.
8)Unplug the CPU and reattach.
9) Ensure your CPU heatsink/FAN is attached properly to the CPU.
10) If you use a variable RPM fan ensure its set for full speed.
11) Retest.
12) If 1-11 do not help power off and test the motherboard outside the computer case to eliminate a case/motherboard power short.
13) Retest. If the board now works check for case problems. If the system still is not working continue…
14) You may have a possible hardware problem. Any device in the system may be a possible culprit. Use process of elimination to determine the cause. Swap out as many components as possible starting with RAM, CPU, POWER SUPPLY, VIDEO CARD (if present) and/or MOTHERBOARD.

Fans run without turning on front switches


Hi Gene,

If you've installed the cpu and hooked the fan to the power supply plug, which is just left of the cpu mount, then the board if connected to the power supply cables, it should start up. Regardless of the front switches. However, you probably don't want to start plugging in the power cord until you have all of your components in place and ready to close up the case. First you can create a shock by just touching the board and that can damage the board. (I speak from my own experience :-( .

But once you get the power switch plugged into the board that should take over turning the rear power supply on and off (Including the cpu fan)

Good Luck and don't forget to leave a rating, based on my solution.

Thanks Mark

I have a power supply that is turning itself off immediately after switching it on it is a new motherboard as well Any ideas why ?


I think either the MB or the CPU is with problems.

Try (2 after 1 works, 3 after 2 works...):
1) only PSU+MB+CPU and Fan - works? beeps like crazy?
2) add memory - works? single beep?
3) add/connect video - any image?

All other connectors off (disks, etc) only PSU, fan and case buttons.


If you don't get past 1), go back to the store and have it tested/returned there.

COMPUTER WON'T POWER UP


Hi,
Three are a couple things you can check/try. Remove the memory, (If you have more than one DIMM load only one). Boot the system. Try each dimm in turn one by one. If your board is old. I see three ISA slots on the board, so it's old. It is possible the thermal tap or thermal grease may have dried up. (This will cause your CPU to overheat & shut down). The grease is located between the heatsink assembly & the CPU. Remove the heatsink assembly. Take a clean rag with a little alcohol on it & wipe off all old thermal grease. (Care full, do not over soak the rag & do not scratch either surface, heatsink or CPU). Double check all connections while in the case. Try booting again. Most CPU fans last for 50,000Hrs or five years. If the steps above did not help, you may need a new heatsink assembly, this will come with a new fan. Lastly, if all of the above has not helped. Check the voltage of the cmos/bios battery. It should test 3volts DC. If it test under replace it. On the outside shot, if you have done all of the above try another known to be good power supply. (If your CPU was bad nothing would turn on, not even the fan).
Give it a once over!

Good luck lieutenant_1!

PC WON'T POWER UP


With nothing attached to the mother board except 1 stick of RAM in the first slot the power supply and monitor attached, and then  it still turns off ; I would make sure the heat sink was clean Reseat the Cpu and try it again. Now if the same results. I would attempt to substitute a different known good power supply. If that would not work, you are down to substituting a different CPU .

Since the only thing connected is the power suppy and the CPU, this is often caused by a power supply unable to provide the power to the MB. You will need to swap out the power supply and that should take care of the problem.
