So yesterday i decided it was time for some spring cleaning and i took apart my old dell, and clean everything from fan shrouds to heat sinks. No water just some cloth. I took the shroud and fan off my graphics card and gave those a wipe aswell, and i put it all back together. Too my shock it wouldnt boot into my OS. Here are my specs before i go further.
Dell Optiplex 780
Quad Core duo Q9650 @3.0Ghz
8Gb trash ram
1Tb WD HDD
512Gb Seagate HDD
EVGA 750 Ti

Its not a hefty build ive been running this for over a year, with either a 2 screen or 3 screen setup. I was even able to play decently new titles like GTA and BF1.
Anyways i put it all back together and it would not boot. I got NO video from any of my cards ports. I had to plug my monitor into the integrated VGA just to see the error message which reads:
Attention: Unsupported Configuration Detected

Action is required

This computer has both a display port monitor attached and a card installed in the PCI- Express slot 1. This configuration is not supported. Please remove the PCI-Express card or disconnect the display port monitor.

For more information or help, please refer to the system documentation.
System halted!

The thing is that there is nothing connected to the onboard display port. Tbh i didnt even know this thing had one until this. The system will not boot at all with the card in. It wont let me go into my BIOS settings or my boot selection with it in either. My card is still under warranty. I can send it back and get another if that is the problem. Ive done a BIOS update and ive messed around with settings in the BIOS to no avail. I dont have another system to test the card on.

I also tried something of a hot swap. I plugged the card in while the system was running to see what would happen. This was as it was booting into the OS, and something weird happened. My integrated I/O can only shit out a resolution of 1280x god i forgot but nothing good. But i know 1280x10?? is the max, But when i got into the OS it had scaled to 1440x900 (which is what i usually use on my 750 ti) a resolution that the onbord chipset doesnt support. I managed to get into my device manager to see just wtf was going on and it had my 750 ti listed as an unknown device with no drivers installed. Although i had nvida control panel and all that fun stuff installed.

Hot plugging a video card is NEVER a good idea. Too many bad things can happen, fried card, fried MB. Pull the video card, hook to the onboard video, go into BIOS and reset to default settings and see if it boots.
