Hi All, Just built a new PC and everything went fine initially, however at some point either a windows update or gpu driver update started causing artifacts on my PC (I didn't notice it at first as it is kinda subtle in windows, cross pattern appearing for a second after closing start menu, text sometimes pixelated, but it is really noticeable in games). I had booted up Witcher 3 before updating and it was fine no worries, but after the updates its a mess of colours and artifacts everywhere. The first time I did the Radeon driver update (using the auto-detect utility) I got error 1603 - general error and the drivers only being partially installed. I then updated windows thinking this may have caused the issue, re-installed the Radeon driver and it completed successfully. Then I noticed the artifacts/graphical glitches (But these may have occurred after the Windows update). To try and resolve this I booted into safe mode, no artifacts or graphics glitches in safe mode. I then ran DDU to clean any dodgy drivers, restarted, with just the Microsoft Basic Display Driver had no artifacts/glitches, however trying to reinstall Radeon drivers, artifacts re-appear. Checked GPU temps playing a game all good max 72c, fans work. CPU temps ok too. Did a Windows Memory test, no issues. Checked connections, re-seated GPU. Motherboard bios is updated, tried a Windows 10 reset, tried installing older Radeon drivers, tried uninstalling Windows Updates, all result in same thing. Nothing is overclocked, all brand new apart from HDD. Is my GPU stuffed? Any suggestions on what to try next? CPU: Ryzen 3 2200g Motherboard: B450M Pro-VDH (Bios date 8/6/18) Memory: 2x 8GB 3200mhz (sitting at 2133mhz currently, haven't enabled the faster profiles) GPU: RX580 4GB PSU: Coolermaster MWE500 SSD: Samsung EVO 960 500gb HDD: WD 1TB ODD: DVD/writer combo Sorry for the wall of text, but I'm outta ideas! Any help is greatly appreciated!
