Hello all, I'm having some problems with graphics cards getting spotty or no detection from my monitor. I have a computer that was pre built by target, I've had it for several years now. A few months back, the graphics card started having issues. The monitor would go black occasionally, and towards the end, it would suddenly act like it wasn't getting a signal at all. I unplugged the gpu and ran the monitor of the built in chipset and had no issues. I just bought a new gpu, and to my immense annoyance, it is immediately having trouble. The computer would boot up fine, but a few minutes in, the screen would flash on and off, and finally just stop getting a signal. I suppose at this point it could be the motherboard, but I don't know. I'm not very experienced with computers, and I was hoping someone could give me some advise on how I might fix this. I don't have a lot of money, so I don't want to replace anything I don't have too, and I really hope getting a new gpu wasn't a big mistake. I just wanted to be able to play games with my friends again. I appreciate any help you can provide.
