In that case

In that case, best case scenario is the video card went bad and the possibilities get significantly worse from there.

Tried to get a new video card
Sep 21, 2014 11:34AM PDT

Well I was hoping it was just that video card so I went into fries electronics and every graphics card I picked up said you must have a CD ROM to install the software. well how can I install the software if I can't see what I'm doing since I have no video? When I asked the sales associate this question he said all graphics card should have a minimum amount drivers to show you what you're doing so your old graphics card should still work a little bit I told him it doesn't work just a little bit, he just looked confused so I put it down and left. Seems like I'm at a dead-end I have no graphics card and can't buy one because I can't see what I'm doing to install it

Here I install the card and get the software from the web. But if there is no display at all, my experience is that you didn't fix the PC.

Hi small world..

best suggestion.. i think firstly boot to safe mode and set your video to a generic VGA reboot to normal mode and adjust your video ..

Maybe?

If you checked your monitor on another PC and it worked, good. Return to original PC and reconnect. Now, open PC case and check the innards for "bad caps". Goto http://www.badcaps.net for examples. If you find bad caps, more than likely can you fix it yourself. If no, swap out mtrbd. or had a pro do the work if cost effective. If not bad caps and is a bad video card, replace card. If you have onboard video use that instead. Basically, you lost signal or isn't allowing the signal to proceed. Even a new video card not yet fully installed will use "native drivers" to provide video, though basic. If again nothing seems to work, you truly have another source of the problem. If though, you have fans or lights working in a PC, that usually suggests only 12V is working, not the 5V or 3.3V check the PSU for proper power outputs or swap PSU out to test or use the "green wire to grd," no connection to mtrbd. just to see if it turns ON. Alas, you gave no clue what your PC is, details matter.

Don't worry about it

Don't worry about it. The OS will fall back on software rendering. Updates to what's happening on the screen will be very slow and you'll have to put up with a really low resolution like 800x600, but you'll be able to see what's going on while you dump the old drivers and install the new ones. That's an especially important step if going from nvidia to amd or the other way around.
