I had no idea where to post this so I just chucked it here :confused Hi I'm new to the forum, and I'm an absolute dummy when it comes to computer troubleshooting so I've come here for some help! My computer shuts down randomly when playing games, or watching youtube videos, or even just for seemingly no reason. By randomly I mean without warning and with no order to when shutting down (could be a minute after beginning playing the game or an hour). The computer also has A LOT of difficulty rebooting, and quite often the monitor doesn't switch on after pressing the power button. Sometimes it will start up first try, other times it can take 30+ restarts before it boots completely. It often gets stuck at the first screen of the startup (has a bit of text and also says "Dual BIOS on the left). It also freezes at other points during startup sometimes and gets frozen on the login screen and on the decktop just after logging on. I have a feeling this has something to do with the power supply but I'm not sure. Here are the computer specs: Operating System: Windows 7 Ultimate 64-bit (6.1, Build 7601) System Model: GA-MA790X-UD4P BIOS: Award Modular BIOS v6.00PG Processor: AMD Phenom(tm) II X4 945 Processor (4 CPUs), ~3.0GHz Memory: 4096MB RAM DirectX Version: DirectX 11 Thanks for reading all this!!!!
