System displaying diagnostic alerts during boot despite normal operation
System displaying diagnostic alerts during boot despite normal operation
So last December I purchased an open box 6900xt graphics card, which I've used for past several weeks... Recently - 2 weeks ago I noticed that, whenever I start up the pc - the POST would give single beep (everything fine) and then 1 long and 3 short beeps suggesting a 'vga error' even when pc starts up just fine and display is displaying properly. This happens mostly during cold boot meaning, that if I restart the computer it doesn't give error beeps. What could be happening here?
It might be a low-voltage CMOS battery, indicating it’s depleted. Based on past observations, the power supply unit could be the source of the issue. I’ve noticed similar problems with older PSUs before they completely fail.
This situation seems unusual given the age of the motherboard and the absence of previous BIOS warnings. Using the GTX 1080 with the Acer Predator XB271Hu and the display cable just a month ago, without any issues, suggests stability. Recent changes include switching to an LG 27GP850 monitor, using a Startech VESA certified display cable, and installing a new graphics card. It’s worth noting that the freeSync monitor might interact with these components, though I haven’t observed any problems. I usually power down the PC during nighttime video encoding sessions. When using Windows, I disconnect the monitor while wearing headphones and notice a strange disconnect sound from the system. The PSU is from early 2017, but it’s a Seasonic Prime Titanium 850W unit with a warranty now extended to 12 years. The system runs on a Cyber Power 780W UPS, which has been in use since 2017 after experiencing some blackouts initially. Stress testing with Cinebench R23 showed power draw around 600W, including the monitor, so power supply seems adequate. The GPU uses three separate 8-pin cables, and Seasonic provided cables without pigtails. Additionally, the beep code doesn’t appear consistently on cold starts—there was an intermittent error during a two-day warm-up period, but not today.
Did you change the CPU settings? If your board has few pins and they don’t match properly, it might cause issues. Check the BIOS to see if the GPU is dedicated or linked to CPU/GPU, then update your chipset and GPU drivers or BIOS. Use the ATI tool to refresh your GPU’s VBIOS. Try connecting via VGA, HDMI, or DVI on the motherboard. If you installed a driver from the Windows update, reinstall it. Refer to the AMD release notes for details and see the relevant chipset driver info.
