The Mobo is on warranty until 2018 courtesy of the so called TUF warranty, but it's ASUS, so you never know. The CPU is still on warranty until March 31 as soon as I can find an AMD CPU container. No matter what I do, it's fans and a single RED light staring at me. I also tried direct key, needless to say it didn't go into UEFI/BIOS either. System won't turn off without using the rocket switch on PSU. and no, I didn't rub it in while using the scotch tape, lightly enough so the words on the CPU disappeared.Ĭlearing CMOS It caused power up afterwards with straight up power up when using the rocket switch on PSU without pushing the power button up front, but still only fans and CPU LED. So without swapping another CPU in, is there a way to tell it's the mobo or CPU? I could find another AM3/AM3+ CPU, but its hidden somewhere in the basement where I can't find it easy. So I heard that even without CPU, memory, and video put into mobo, the mobo is still supposed to beep or at least the other LEDs were supposed to light up. There's only the green Motherboard power LED and the Red CPU Led and the fans. Even though I didn't put in GPUs, Memory, nor GPU, the LEDs for Video, Memory, and boot device stayed off. Now I took everything off except CPU, heatsink and CPU fan. Tested with a different set of RAM, only one bar, but problem with same status remains. Tested with only one bar of RAM, you know it. Tested with another known good PSU, ditto. Only RAM, heat sink, and GPU, same red LED and fans and nothing else. I took everything apart and put the mobo on the mobo box and got to work. The system stayed on with fans and the LED and there was no emergency heat shut off by the system.įrustrated I started breadboarding. (Both the 24 and 8 heads power were connected on the mobo before anyone ask). So I decided to take off the heat sink and felt the CPU when I switched the thing on. no beep even though I put in the little speaker.Īt this point I decided to pull the second GPU out, no cigar. only way to shut off power is to use the rocket switch on the PSU.Ĥ. the optical drive has power and is able to pull itself out when I push the button.Ģ I try to push down Power button for a long time but the system does not turn off. there was no signal on monitor and I noticed the red CPU Led was lit and stayed lit. I put the system together and push power.ġ. Mobo:Asus Sabertooth 990FX Version 1, I think. Power button able to turn system on but not off. TL DR: Only CPU LED stays on, fans only, nothing else no matter what I do. Dominator plats and gskill are the way to go.My system won't boot and CPU LED stays on with no post and no other LED lit. Its been nothing but trouble for this board.
#Red cpu led series
If your ram is Vengeance series from corsair get rid of it.
Final step is to take it to a shop for troubleshooting. Try different video cable and video inputs on monitor. Turn monitor power on and then hit the power button, give the mobo 5-7 minutes, you should notice gpu and cpu fans spinning up if not try a different psu. Ensure power cable is fully plugged into monitor and power strip/wall outlet, hook up and ensure psu power cable is hooked up fully to psu and in wall or powrr strip. ensure monitor cable is hooked up to your monitor fully and set to correct video input.
#Red cpu led ps2
Hook up the keyboard and mouse using the usb ports closest to the ps2 port. Ensure atx, eps 12v (at top of mobo towards rear) hooked to mobo, then pcie power is hooked up to gpu properly. clear the cmos using the jumper (read your manual), put jumper back in its spot, apply tim to the cpu and reattach heatsink to cpu mount bracket and fan to cpu header. Disconnect power totally, ensure ram is in slots 2 and 4 from left to right, ensure to shove gpu into pcie x16_1 fully seated, hook up a monitor closest to the screw side if the pci bracket.
Since the socket lays on 1 side and the latch bar is closer to the pcie socket, the tip of the latch bar faces left, ensure when you insert the cpu the letters are closer to the ram and not up and down on the mobo. Ensure mobo is placed on the box it came with ,psu,gpu, out of case completely, Take the heatsink off, take cpu out of socket, ensure you dont have any bent pins on the cpu.
