I have an HP 500 189. I recently upgraded from the integrated HD 8570, to an RX 550. I went from playing CSGO at 720p at 100+ fps, to 800x600 at less than 60 fps. It is ridiculous, because i got a new Power supply, new gpu, and got it professionally installed at Memory Express, and it is working like crap. One thing I noticed is my usage flashes between 0%, up to 20%, and all of a sudden 100% for a few seconds, then drops down again. Temps are normal. Need help!
