Artifacting, black screens, crashes under load, and loud or dead fans — desktop graphics cards diagnosed and repaired. Graphics card faults fall into patterns that point to different fixes, and we identify which one yours is before any money changes hands. Checkerboard patterns, colored lines, or corrupted textures on screen are the signature of failing VRAM or its memory controller — a board-level fault, not a driver problem. Crashes or a black screen that only happen under gaming load usually trace to heat or power: factory thermal paste that dried out years ago, heatsink fins packed with dust, thermal pads that have gone crumbly over the VRAM and power stages, or a fan whose bearing has failed so the card cooks at full load. A deep clean, fresh paste, new pads, and a replacement fan bring a surprising number of "dead" cards back to stable temperatures. On the newest high-wattage cards that draw power through the compact 16-pin connector, we also inspect the plug and socket — a connector that was never fully seated can overheat and melt, and that damage is visible before it kills the card. We separate hardware faults from driver and power-supply problems by testing the card on a known-good bench system, and we are honest about the one thing we do not sell: reflowing a genuinely failed GPU die is a temporary revival, not a repair, and we will tell you so. Tech Genius handles graphics card (gpu) repair for customers across Manchester, CT and nearby towns, typically while you wait.

Common questions
Before you come in
My screen shows checkerboards and weird colored patterns — is the card dead?
Not necessarily, but it is a hardware symptom, not a driver one. Artifacting like that points at the VRAM chips or their memory controller. Sometimes it is heat-related — failed thermal pads letting the memory run too hot — which is fixable with new pads; if a memory chip itself has failed, we tell you honestly whether repair or replacement makes more sense for that card.
My games crash after 10-20 minutes but the desktop works fine. Why?
That pattern is classic overheating or power delivery. The desktop barely works the card; a game pushes it to full load, where dried-out thermal paste, dust-blocked fins, or a failed fan lets it overheat and the driver resets or the PC shuts down. We verify by logging temperatures under load, then service the cooler — and we also rule out a weak or failing power supply, which produces identical crashes.
Is it worth repasting a graphics card, or is that snake oil?
On a card more than a couple of years old it is one of the most effective services there is. Factory paste dries and the pads over the memory and VRM crumble, so the same card that once ran quiet climbs into thermal throttling. Fresh paste and correct-thickness pads routinely drop hotspot temperatures dramatically and bring back the performance the card had when new.
The 16-pin power plug area on my new card looks discolored — should I worry?
Yes — bring it in before using it again. The compact 16-pin connector on recent high-wattage cards must be fully seated; a partial connection concentrates current on a few pins, which overheats and can melt the plug and socket. Caught early it may need only a new cable and a properly seated connection; ignored, it can destroy the card’s power input.
