Hi, I'm guessing as a new member I need to state my problem here and can't post a new thread directly, right? MOBO: AsRock B650 Steel Legend WiFi. Well...There's an issue I need to troubleshoot. I've built my computer a year ago, AMD based. And it was working fine (though sucked in terms of graphics issues since windows 25H2 retarded update). A few days ago it fired up nicely, I played a bit, done some web browsing and left it for like an hour. It went to sleep mode (did not switch off the components, just the screen) and it never recovered from that. I couldn't get it to switch the screen on, I forced a restart and since then (or even before the restart, I didn't catch this) the CPU POST diode is always on (red). All of the components and peripherals except for the screen come alive when I switch the computer on. All the RGB components work. However the screen doesn't show anything even for a split second. I hooked up a laptop to the screen - the screen works. I hooked up a speaker to the motherboard, started the PC without any RAM so far - not a single beep (I checked the speaker and it works alright). I tried just 1 RAM stick as well and this doesn't help. I checked all the power cords, especially CPU ones and they sit tight on both ends. I reset CMOS twice according to the quick start guide which came with the MOBO. I'm about to take the CPU out, examine pins and stick it back in. I don't have any spare, compatible CPU, MOBO, GPU or RAM to test by replacement. Is there anything else I can do to find the offending component or do I need to RMA the CPU straight ahead or pay for troubleshooting at some local shop?

Try doing this: https://forum.asrock.com/forum_posts.asp?TID=630&title=how-to-clear-cmos-via-battery-removal" rel="nofollow - https://forum.asrock.com/forum_posts.asp?TID=630&title=how-to-clear-cmos-via-battery-removal Make sure to leave the system fully disconnected from power for about an hour. Sometimes a failed sleep state can cause the system to fail to POST, typically following the linked steps will resolve the issue if it is not a dead/dying CPU. If this fails then I would have a local shop look at it for you, it may save you time, effort and money if they can at least determine what the fault is caused by. Good luck. -------------
