Posted March 2, 2020 Hello I built new pc and it didnt post, no hdmi1 found on monitor, looked on MOBO cpu light was on. Specs: MOBO: B450 TOMAHAWK MAX CPU: RYZEN 5 3600 RAM: CORSAIR VENGEANCE LPX 16GB 3000MZH GPU: MSI RTX 2060 VENTUS XS PSU: CORSAIR RM650X 650W SSD: 1TB KINGSTON KC600 CASE: DEEPCOOL MATREXX 55 V3 ADD-RGB 3F Everything is plugged in, fans work, usb ports kinda work(only my keyboard does not work only when i turn on and off psu for a sec), took out ram tested it in every chanel it worked fine, removed ssd, removed gpu nothing. Removed cpu to see if pins are broken they are not. Updated bios with flash, cleared CMOS nothing. At start for ~0.5sec boot light is on then off then cpu light turns on for ~3-4 sec then it turns off for ~3-4sec then it turns on again and MOBO leds at the back turn red.

Sorry for bad english Something doesn't add up? How have you validated the both RAM channels work and also flashed the BIOS when you aren't getting a POST? As far as I know, you can't do either of those things unless you are at least POST ing and getting into the UEFI. Share any interests with me?

Perhaps a silly question, but you are certain the HDMI is hooked to the video card and NOT the motherboard? Were you able to/ did you try to get a POST on the previous BIOS version? Another thing I have had varying degrees of success with that may be worth a shot is to: - unplug power cord - press and hold the power button on your case for 30-60 seconds - replug the power cord - reboot Share any interests with me?

Posted March 2, 2020 i would also try unplugging one ram stick, and see if that works. if not, try the other stick. It could be that one of your sticks could be dead Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

I tride to get post on previous bios same thing. I will try to unplug psu and hold power button. But cpu thing is wierd it looks like its going to post some times on monitor it shows - or red screen but then fans start going slower and cpu light turns on Link to comment Share on other sites More sharing options...

If you updated the BIOS to the latest version, you should be good to go on that front. Should be non issue. Here's a bunch of other things I'd try: - move video card to the second slot - try another video card - try to power on with no RAM at all. If you have a speaker hooked to your motherboard, you should get a whole bunch of sparatic beeps and no POST. If you can't hear the beeps, could be bad MOBO - try to power on with no CPU at all. Not sure what to make of this, but if you somehow experience the same issues with no CPU whatsoever, could probably narrow down the issue to either the CPU or MOBO - power on and let it sit for like 5 minutes. Sometimes ram training and first boot on new bios just take a while. Screen flashing and apparent additional resets can be normal. Share any interests with me?
