Trying to setup new gaming PC
After completing hardware setup on boot first noticed error on monitor "No (cable type) signal from device - going into standby mode". Rather than goto standby, boots into bios which displays just fine. Tried 2 DP and 3 HDMI cables - no change.
Also noticed fans on GPU would spin for 30 secs or so then stop. Set all fans to full speed, no change - 30 secs then stop. Tried Dell's built in diagnostics and self diagnostics but that didn't help at all.
Removed and reseated GPU and Memory several times - no change. Further troubleshooting discovered DRAM Fail and GPU not detected on motherboard status LED's. Removed GPU and replaced with working GPU from current desktop. Replacement GPU fan spins continuously but nothing has changed so assuming a bad motherboard.
Thought all issues, may be driver related since no OS has been installed. Cannot get past bios or boot from USB thumbdrive or USB Hard drive.
Please help!!! Any assist would be appreciated....at least confirm replacing MB is best option going forward.
