I have an ASUS Sabertooth 990FX mobo. Recently, the DRAM_LED has been a solid red colour, and the compute doesn't even reach a post screen. However, sometimes it doesn't go red and the PC boots, but it still shuts off after about 5 minutes. Could it be a RAM problem and a PSU problem at the same time? Sometimes to CPU_LED flashes red once and the PC shuts off, however that hasn't happened recently. I did have a bad habit of leaving it on in sleepmode during nights, so I could have damaged the components somehow. I've had problems in the past but I could always use this website's advice to fix it. This time, however, I have to personally reach out with you lovely people because I feel my case just doesn't fit on any previous questions. Thanks!
