Computer starts up, yet can't send a post. Desktop glows a harsh crimson.
Hello, this is my first time here. I own a computer for roughly three years, built it myself, and it performed excellently. One morning I powered it up and everything seemed to work except the monitors, keyboard, mouse, and drawing tablet. The webcam and microphone were getting power, but all other components showed no signal. When I opened the case, the Dram indicator flashed red for about ten seconds before turning off. The CPU indicator also lit red briefly. After some research and a long night of troubleshooting, I tried several fixes: reset CMOS, replaced the CMOS, reinstalled RAM, double-checked each stick, tested individual slots, verified CPU connections, confirmed no damage, reinserted the CPU and cooler, removed the CD drive and hard drives/SSDs. Nothing resolved the issue. Now I’m pretty sure a motherboard replacement is necessary. Before heading to a store, I’d appreciate your advice. Here are my specifications:
- Motherboard: ASUS Z170-A LGA 1151 Intel Z170 HDMI SATA 6Gb/s USB 3.1 USB 3.0 ATX
- Power Supply: EVGA SuperNOVA 750 G2 220-G2-0750-XR 80+ GOLD 750W (fully modular)
- RAM: Corsair Vengeance LPX 16GB (x2)
- CPU Cooler: Cooler Master Hyper 212 EVO
- Graphics Card: ASUS ROG GeForce GTX 1070 STRIX-GTX1070-O8G-GAMING (8GB, 256-bit GDDR5)
- Processor: Intel Core i7-7700K Kaby Lake Quad-Core 4.2 GHz LGA 1151 91W
- Case: BX80677I77700K
- Operating System: Windows 10 64-bit
Thanks in advance! I’m really concerned about this situation.
You've followed all my recommendations. One more suggestion: consider switching to a different stick/kit or using the original kit in another system.
I don’t have any extra RAM left. But I just bought the second batch of Corsair memory, and even after removing the older version, the issue still exists. It seems I might have needed to upgrade it again.
Windows includes updates in a beta testing phase. A rollback could help. Checking drivers, BIOS versions, and update dates might not resolve the issue. It could be hardware-related. The key point is whether the change date aligns with when problems began. RAM failures can be quiet, making this a tricky situation. This seems like a weak argument.
Currently, I’m unable to power on any of my screens or use the keyboard. It seems like a hardware problem. I’ve tried everything and still can’t reach BIOS. Maybe upgrading to a newer model would help. It’s a bit pricier, but not too much.
