Is your monitor plugged straight into the GPU or the Motherboard?

Sounds like you're running onboard graphics.

Other possibilities: bad PSU not putting out enough clean power. Thermal throttling on the CPU due to bad cooler install or not proper thermal paste application. Check all power connectors to the GPU and motherboard, a single 4-pin connector not fully connected can cause issues.
