Video cards that are 2 or 3 generations old are very affordable online at places like bestegg.com and tigerdirect.com.
I agree with checking out the video card. I had to replace one a few months ago, and while I was waiting for my new one to arrive, my computer wasn't able to run any games. If I tried to run rom, it would close just as you stated, but it was every time. This might mean you have a dying GPU if it only happens sometimes.
The thing I'd be wary of is that in late last year and early this year, the prices of GPUs skyrocketed due to cryptocurrency (you can Google it). They seem to be coming down now from what I am seeing, but they still going down. May be in your best interest to wait a bit to see if it continues and figure out exactly if your video card is the problem while saving a few bucks.
Also, I think the sites mentioned in above quote are "bestbuy" and "newegg" combined to bestegg. There are plenty of sites out there that will give you the lowest prices available for them like pcpartpicker.
