Won't boot to bios, no video signal, fans and RGB lights on Predator Orion 3000 PO3-640-UA91

Everything was dandy last night.

This morning it won't boot, no video signal to monitor. fans are running RGB lights on.

tried to boot to bios, it's a no go. fans are running, for CPU and for GPU

Things I tried:

removed added memory cards, removed and reseat OEM memory, remove reseat video card, swapped HDMI cable, swapped monitor, unplugged-replugged power connectors. tried a different wired keyboard to attempt to get to bios by tapping delete key on start up.

what else should I try?

thanks

check your power supply

clean or replace the RAM

i had the same exact issue with mine and all i had to do was unplug the DP cable and hook up an HDMI and it worked then i went back to DP and it has done it a couple times since and also turning the monitor on and off helped the 2nd time i was told it's a handshake issue between the GFX card and monitors. i also thought it was fried or something i have no idea if yours is the same issue but try different cables if you haven't and mine seems to only do it on my acer predator monitor hooked to an acer predator Orion 5000 desktop makes no sense but whatever it is what it is and my fans were running and my lights where on but flashing through the colors slowly is yours doing that ?

well i know when i did all the research i could i got the 5000 series it comes with a lot better internals and you can replace anything within it. and it's a much larger case for expansion options etc so maybe the 3000 limits a lot more I'm not sure I'm no expert but almost everyone here who has bought one has issues of some sort i mean with the 5000 in my eyes its only weakness was the stock cooler so i replaced that but i don't like liquid cooling and all the problems with them so i put in a Noctua NH-U12A and it rivals most liquid coolers anyways i think the best cooler only does 8-10 C better anyways like that matters. all my games run between 38-46 C @ 1080P now and after reading your last post i see that you made a lot of changes and yeah i guess anything can happen when we do that and try to troubleshoot then because at first it seemed very easy like my issue, but nope was something totally different.

forgot to mention. I swapped the GPU from my other working PC.

thanks for tips.

I got the PC to boot after I unplugged the CPU's watercooler USB connection. (I switched out the small aircooler with corsair H100 water cooler after the purchase.)

The corsair watercooler needs SATA connection for 12V power and a USB header connection which this MOBO does not have, it is to work fan power curves in corsair's software - ICUE.

It worked for a while then the monitor started flashing once or twice. Now I have unplugged the ACER's sata connector from the water cooler and testing it as we speak. (powering the corsair waterpump from a different PSU)

At this point here is what i think may be going on.

Since this ACER 3000 P03-640 run on this weird PSU (new intel standard ATX12V0) that this PSU only supplies 12V to the MOBO and the MOBO makes its own 5V and 3.3 V for SATA.

I am guessing the corsair's pump and this MOBO does not play well for 2 reasons:

1) the MOBO has no USB header, and I had to use a USB 2 to USB header cable to make it work

2) the 12V /5V power the corsair waterpump needs does not like the power coming from the MOBO.

3) somehow, something feeds dirty power back to the MOBO, orit could be this neverheardofbrand-> (Chicony ) PSU, that came with the PC. and the PSU is just taking a dump.

I am Running into the same problems here: this PC uses a unique/ rare PSU, plus ACER cheaped out by not soldering a USB header to the motherboard.

Chugzilla, yes I've tried a few cables DP, HDMI. no luck. But I agree with what you said and have experienced exactly what you mentioned, many times with different PCs. Sometimes the PC does not recognize DP connection.

I am realizing that this PC was specifically made with the least amount of parts and made where it could not be up updated much or modified. Can not be OC-ed, has zero USB headers, the extra PCI1 port is completely blocked by the GPU, there is only 2 SATA allowed. NO HDMI connection on the MOBO to run it /test it without a GPU.

I think i made a mistake buying this unit. :(

agree!

I will try to work with what i have including lots of spare parts i have from other builds. The guts of theis PC will go into a hyte Y40 case today with a new PSU and the water cooler.
