I think I fried my mobo installing a new gpu

[rev2red007]

So I bought a new gpu (gigabyte r9 290) for my set up . Before installation ; I uninstalled the AmD catalyst drivers from computer. computer told me to restart but instead I just turned it off. Not sure if that led to the black screen later but I did remember I never rebooted the computer like it told me to . So I took out the old gpu ( Radeon HD 6970) , installed the new gpu , plugged in everything and powered up my PC. I got a black screen upon power up , everything seems to run normal, fans, CPU fan, new gpu fans all spinning . So I left the pc running for about 5 mins trying to figure out why I'm having a black screen , then all of a sudden I smell something frying up in the PC , no smoke but def something fried then the PC shuts off . Tried turning pc on afterwards but no power to anything . So I try to isolate the problem starting with the psu ( evga 1000w GQ) . I unplugged the CPU power , and plug a jumper into the 24pin connector ( jumper came with my psu) . All my fans work including psu fans . So it wasn't the psu fault . So did I fry my mobo just now ? I hope I didn't fry my CPU as well . After reviewing all the steps I took , I did notice while installing the gpu it didn't fit into the pci slot quite as nicely compared to the old gpu which slides in like butter , I did however got it to fit in the end . I don't know if that might of damaged the pci slot which in turn caused my mobo to fry . So what I'm asking is can the gpu possibly fried the mobo ? Should I buy a new mobo , I'm afraid of plugging the new gpu into that one as well , what if it fries it again . should I just return the gpu and get another ? Thanks in advance

My PC specs :
MSI mobo 970 A
4x4gig ballistix ram sticks
AmD 8 core processor 4.3ghz
1000w EVGA GQ psu

ps : my old gpu was working fine before the attempted upgrade. And this wasn't the first time I installed a new gpu . So I don't know what went wrong this time . So what should I do next ,

1| Not to rub slat into your issue but if this isn't your first time then how can you be unsure if the GPU fried the board or not?

2| It'd be a good idea to disassemble the entire system and reconnect the components atop of your motherboard box aka breadboarding and see if the system boots up upon introduction of each component one by one.

3| When you've stripped the entire system, it'd be a good idea to start smelling each component carefully to identify the source of that burning smell, probable a power regulator might've fried. The PSU could be one suspect/culprit.

Well I have replaced a few gpu and build computer from scratch a few times throughout the years , but that doesn't make me a pro , so obviously I'm still a newbie when it comes to identifying issues if anything went wrong . The previous attempts went well so I'm just doing what I did before , but not sure what went wrong this time around.

As for coming to the conclusion that I might of fried my mobo , I did the psu test . Unplugging the 24 pin connector to the motherboard and plug a jumper to it to see if psu power up . The psu fan and all fans connected to it spins . But when I plug back the 24 pin into the mobo , the whole system doesn't get power .

As for smelling each component to see which one might of burned . Since my tower is prettty spacious I was able to stick my head in to smell the CPU , psu , ram sticks. Those components did not have a distinct burning smell to them . Upon smelling the new graphic card , the right heat sink have a different smell compared to the left , I'm not sure if that's a "new" smell or burnt smell.
