MSI Ventus RTX 3070 Not Detected But Fans Spinning - Solved.

MSI Ventus RTX 3070 2x OC not detected by your PC but the fans are spinning? In this repair video, Frazer from GPU Solutions walks through the full diagnostic and repair process to bring this dead GPU back to life. The card had no shorts on the 12V PCI or 3.3V rails, but PEX, core, and memory voltages were all missing. Under the microscope, heavy corrosion and flux residue revealed this card had been previously worked on. The root cause was a faulty endgate (AND gate) chip responsible for the power-good signal to the core MOSFETs. 🔧 *Diagnosis & Repair Steps:* • Voltage rail testing — 12V PCI, 3.3V, 5V, 8-pin power measurements all checked • Visual inspection revealed the card felt flimsy, likely dropped at some point • Under microscope: corrosion, flux residue, and GPU chip not seated correctly • Traced the missing PEX, core, and memory voltages to a faulty endgate chip • Endgate tested: 3.3V input present but no 5V output — confirmed defective • Replaced the endgate from a donor board using hot air soldering under the microscope • Post-repair: PEX and memory voltages restored, card detected immediately • GPU-Z shows full card recognition, Heaven benchmark runs without artifacts 📋 *Chapters:* 0:00 - Intro: Card Not Detected, Fans Spinning 0:34 - Voltage Testing: 12V PCI & Power Rails Check 1:44 - Visual Inspection: Card Shows Signs of Physical Damage 2:31 - Teardown: Removing the Cooler for PCB Inspection 3:39 - Microscope Inspection: Corrosion, Flux & Loose GPU Die 5:23 - Identifying Previously Attempted Repairs 7:58 - Power Supply Connected: Tracing Missing Voltages 10:01 - Pinpointing Missing PEX, Core & Memory Rails 12:09 - Faulty Endgate Chip Diagnosis: Input Present, No Output 15:07 - Donor Board Sourcing & Endgate Replacement 19:59 - Soldering the New Component Under Microscope 25:05 - Post-Repair Validation: All Voltages Restored 29:02 - Card Detected!
