Can a graphics card with green line artifacts or crashing be repaired in Hyderabad?

Yes! Display artifacts, checkerboard patterns, and driver crashes (Error Code 43) are frequently caused by failing GDDR6/GDDR6X memory chips or micro-fractures in solder balls. Our lab runs MATS/MODS memory test utilities to locate the specific failing VRAM channel and desolders/replaces the chip under an infrared BGA rework station.

Can a shorted GPU that trips the PC power supply be fixed?

Yes. When a graphics card immediately shuts down the PC or trips the PSU on startup, the fault is almost always a blown 12V high-side DrMOS/MOSFET on the GPU VCORE or memory power rail. We isolate the shorted component with thermal imaging and solder in an original replacement.

Graphics Card Problems We Diagnose & Repair

Component-level solutions for gaming GPUs and creative workstations.

Screen Artifacts & Green Lines

Checkerboard blocks or purple lines caused by defective GDDR6/GDDR6X VRAM chips. We run MATS/MODS memory tests to identify the exact channel and desolder/replace it.

No Display / PC Trips Immediately

A blown 8-pin or 12VHPWR input MOSFET creates a 0.00Ω dead short on the 12V rail, triggering PSU safety shutdown. Isolated under ShortCam thermal camera and replaced.

Device Manager Error Code 43

Windows fails to load GPU drivers due to failed VRAM solder balls or corrupt VBIOS SPI ROM. Restored through BIOS re-flashing or infrared BGA reballing.

Fans Spin 100% with Black Screen

Missing auxiliary power rails (1.8V PLL or 0.8V VCORE). Caused by failing Richtek/uPI Semiconductor buck controllers or missing power-good signals.

Thermal Paste & Pad Degradation

Hotspot temperatures reaching 105°C causing severe thermal throttling. Full overhaul using high-conductivity K5 PRO viscous thermal paste and premium thermal pads.

PCIe Gold Finger Repair

Heavy GPU sag or transport shock cracking PCIe slot fingers. Restored via copper foil micro-soldering and structural epoxy under stereo microscope.

Honest GPU Policy: If a graphics card has suffered physical silicon die fracture or internal layer core burnout, component replacement cannot reverse the physical damage. We verify core resistance on our multimeters first and inform you transparently.
