Good day! Computer crashed last week, I with a tech did some troubleshooting and found out that the video card and PSU is defective and not working. I am buying the PSU next week but couldn't afford one video card at the moment, I want to use the computer for some things like checking emails, watching a movie and some dvd burning. My question is, will it affect the performance of the computer without the video card? I hope some techie can answer my question. TIA!
