VGA light activated but no screen visibility.
VGA light activated but no screen visibility.
I opened my PC this morning and noticed no display, even though it was functioning properly the night before. The last activity before shutting it down was watching TWD, and I didn’t modify any BIOS settings.
What I attempted:
- Reset CMOS battery
- Boot with a single RAM stick
- Switch to a different GPU (old GPU didn’t work)
- Insert GPU into another PCIe slot
- Check display on another monitor
- Swap PSU cables
- PSU is new, 3 months old, cables appear intact and connected
Components:
RYZEN 7 2700X
MOBO: MSI B450 PRO CARBON AC
6900XT/ RX 580 8G (old GPU)
RAM: Corsair Vengeance Pro
PSU: EVGA Supernova 850gt
One of these options, or all of them, are dead: CPU, MoBo, RAM.
You'd need a second, compatible PC to test each part separately and identify which failed.
If you lack a second compatible PC or prefer not to go through hardware testing, take it to a repair shop and have them diagnose and fix the issue.
Probability of failure: MoBo - likely, RAM - possible, CPU - unlikely.
I don’t have a second PC to try them on, so I only managed to start it using the new drives I bought three months ago, and it didn’t work. This is really disappointing—how did my motherboard just fail?
Is the existing RAM compatible with your setup? Ideally, using just a single stick of older RAM would be best.
It's not that way. I've searched everywhere I could, but nothing worked.
Hardware often fails without any clear cause. That's why a warranty exists. If no hardware ever breaks, there would be no reason for a warranty. The most practical solution is to have PC diagnostics at a repair shop. It's usually a faulty motherboard, though other parts might also be involved.
