I was trying to repair my computer that will not boot after swapping cases. I believed that the boot drive was possibly in a different SATA port so was trying them all. I needed to remove the GPU to access something. I started it up without realising the GPU was still removed. I put it back in and now I can no longer see anything on the monitor at all. No BIOS screen or anything. I tried another GPU and it was the same. I also tried both DVI ports.

 

MSI 970 Gaming Motherboard

Sapphire HD 3870 GPU (both)

 

I was hoping to have this setup going today with the new case and GPU (I was still using the old one to uninstall the old drivers) but I'm just getting problem after problem. Help would be greatly appreciated.

Go over the motherboard mounting, IO plate. Check that the video card is going in all the way. Check power to the video card.

Anyone have any ideas? I've contacted MSI but they haven't responded. I can't see this being anything but a problem with the motherboard. I have tried everything else.

When you turn on your pc do the fans come on?

Do you get video from the integrated graphics?

Yes the fans all come on. One thing I noticed was that the fan on the GPU comes on full boar then slows right down. Goes on full then slows again. It continues this over and over. It is common for the 3870 to do this (in my experience) but I don't recall it doing this in POST/BIOS stage before, only in Windows (could be wrong)

 

Here's what's been annoying me most with this: the 970 has no integrated graphics. If it did, then I could at least use the PC, or if it had no signal then I would know for sure the mobo is stuffed.

Sounds like a failed graphics card, though i'd like to hear what other users think.

The GPU works in my other PC. But I have had trouble with them before and thought they died. (Yes both of them simultaneously seemed to have died) Maybe you're right. I'll try the 950 when I get a chance. But was just concerned that I could damage the new card if the mobo was faulty.

dumb question, but did you double check to make sure all the power connections are hooked up, and hooked up right? You didnt happen to confuse a 8 pin PCI_E connector with a 8 pin CPU connector, or something similar?

No. There are no connection issues full stop.

Is this a similar case? I just had this happening to me a few days ago:

http://www.bleepingcomputer.com/forums/t/600617/no-video-signal-from-gpu/

 

As ive read somewhere else, its possible the computer has hanged itself in a sleep state. What most people do to fix this is to remove all power to the computer, then use a small tool like a screwdriver or something to remove the small circular battery on the motherboard. Then hold the power button for 30 seconds and put the battery (clock) in again and power up. Didn't work for me, but its worth a shot.

thats called resetting the CMOS, and more often then not you dont have to press the power button at all, just remove the battery for 30 seconds to a minute. Some motherboards have a jumper that you can move to make it easier. It is worth a shot though, it definetly couldnt hurt.

It worked! Thank you so much!

 

Can't believe I didn't think of this. I was thinking that graphics were somehow disabled because of booting without a GPU.
