Hi there, I recently got myself a new case, PSU and SSD and transferred everything in my old systems case into the new, sans the old garbage PSU. This entailed a complete system tear down and rebuild, part for part in which there are a number of things that could go wrong. Now I have a tower which gets power, the fans spin, the little red light on the Mobo next to the 24 pin power cable lights up along with my GPU, the case light by the power button lights up, and I can hear everything running.

However nothing goes to my displays. They remain blank, as if no data is going to them. I checked the cable connections, everything is hooked up as it was previously. However, my new case, a Thermaltake Level 10 has some wires that simply don't fit to my old Asus M5A97 mobo and or SeaSonic 750W PSU. This seems to be the fan controller and top exhaust fan, but could be something more. Yet, I have things hooked up to my motherboard for power and a data where applicable for CPU, GPU, HDD's/SSD and Blue-Ray Drive.

Given this, could any venture what is wrong to be causing no display at all going to my screens when I hit the power button? I would at first assume the GPU, but it's slotted in, lighting up and the fans are running so its at least getting power. I'm fairly certain my Mobo has at least some form of integrated graphics to run my bios and windows at a very basic level as well.

Did I fry my motherboard? If so, why is the fans on everything working, and the board lighting up near the 24 pin power cable to suggest everything is a go? o_O Confused as to where the problem lies. Do you folks need more info, if so, ask.

I checked all cable connections, took apart the RAM, GPU, CPU w/Fan and hooked it back up. Same thing, system turns on, no strange noises, mobo lights up near power cable as it should, CPU fan purrs as it runs smoothly, GPU lights up and the fan blows. Monitors aren't picking anything up.

I'm running dual monitors, and I've tried DVI-I, DVI-D and HDMI .

@WiIlliam, I've got no Mobo video output? That I can see anyhow. So I suppose this means no onboard video support from the Mobo.

Other thoughts/suggestions?

Yeah, my M5A97 is the oldest version, not the EVO or 2.0. I checked, no onboard. I removed everything but the network card and the HDD's and Blu ray from the bays, then put it back together earlier. Same deal. Considering I've used two separate monitors which work just fine, with 3 different cords, it's got to be something inside my comp, not the peripherals.

I wont have time to check again tonight, company incoming which will take up my CPU breakdown and repair station until tomorrow. However, should I do a trial and error test with a different GPU and see if the GPU is busted. If I do and neither card solves this issue, whats the next step? Assume it's the Mobo?

If you're 100% sure that your cables are hooked up correctly, then you should test the GPU in another system. If it works elsewhere, it probably means that your motherboard is the problem. You may have busted the PCIe connector when you remove/install the GPU. Sometimes there is dust stuck inside the PCIe connector. Try to gently spray some compressed air inside the connector and see if any dust come out.

ahh sorry amd so no onboard, that board has a second pcie slot correct?

have you tried the other slot?

many bigger cards if not supported will flex your pcie slot and can damage them.

but as said above you will want to test in another pc as well

I have tried the other slot and an older card both. Rules out gpu. Lacking another mobo or functioning cpu to swap and test I believe my options have come to paying a repair shop to diagnose. Unless you folks have something else I can try.

No other pc, no tools but screwdrivers. Seems to be either mobo, cpu or a not fully functional new psu from seasonic which is still powering lights and fans. Or something else I am ignorant of.

did the old card have a power connector on it?


no video could be even just memory

did you try only a single stick? try both of them. one bad stick can cause this and its not hard to zap one accidentally.

since its not working in either slot of with a different gpu that seems like the next step.

if its not that I would lean more towards the mobo, seasonic stuff very rarely is bad

This ended up being an easy solution, I took it in to have a tech go through my system. My sleep deprived self made a tiny mistake in the rebuild. Instead of putting the I/O shield into my case before the Mobo, I stuffed it against the back of the tower at the end. With one of the prongs lodged into the USB 3.0 port, shorting out the entire system. >.<

However, bad things happened with my CPU socket and CPU the day I got it back when I tried getting the cpu fan off to reseat my memory again. It wasn't registering all of my memory so I took the CPU fan off. Somehow in the 3 days since I had reseated my CPU and applied thermal paste, and then took it off, the thermal paste acted like glue between the CPU and heatsink. Taking the fan off tear the CPU out of the socket, and broke the socket lock in the process, and ground the hell out of the CPU. Destroying both CPU and Mobo.

I had to charge $10000 to get a haswell-E 5820 with an Asus X99-A board and 32 gb of RAM with Win7Pro 64 to just rebuild with intel. So, upgrade, but I'm broke for months now. WEIRD for that to occur, just getting stuck to the heatsink, enough that pulling off the cooling fan it was attached to would actually break the mobo socket lock.

Thanks for your help, didn't solve my issue, but gave me other options to test and try to rule things out.

happens all the time, I put new paste on for and ran it hard for two days and went to swap the heatsink out and it was glued.

most of the time you want to do it when it is warm and wiggle it around to loosen it. stubborn ones you need to use floss and run it under the heatsink.
