I have a Cyber Power computer with a Radeon RX570 graphics card. Some times after start up or wake up, My screens go blank and I get a message that there is no signal and I have to restart to try again. It has always done fine after restart. However today I restarted it three different times and it kept happening. I updated the drivers per the latest update. I also pulled my cover and checked the graphics card to be sure it was seated well and the wires were not pinched. It has performed well for the rest of the day. I would really like to figure out what this might be and get it fixed. I don't really video game but I do play a lot of online poker. Any help or suggestions would be appreciated.
