Computer Repair in Manchester, CT
Desktop PC won't turn on, running slow, or overheating? Local same-bench diagnosis, honest quote before we start, and your files kept safe. We repair desktop towers, custom-built PCs, and all-in-ones — not just laptops. A computer that will not power on splits into a few clear causes we test in order: a dead power supply (no fans, no lights at all), a failed motherboard or a dislodged stick of RAM (fans spin but nothing appears on screen, often with a pattern of POST beep codes), or a drive and operating-system problem (it powers up and posts but hangs before Windows loads). A machine that boots but crawls is almost always a dying mechanical hard drive or a full, failing SSD, or malware and startup bloat — moving the operating system onto a healthy solid-state drive is the single biggest speed fix on an older computer. Overheating and random shutdowns under load usually mean dust-clogged heatsinks and dried-out thermal paste, not a broken processor. We diagnose which of these it is before quoting, and we can recover and migrate your files onto the repaired or a replacement machine. Tech Genius handles computer repair for customers across Manchester, CT and nearby towns, typically while you wait.
Devices we cover: Windows desktops and towers, custom-built gaming PCs, and all-in-one computers.

Computer Repair — questions
My desktop turns on but nothing shows on the monitor — what is it?
When the fans spin but the screen stays black, the computer usually is not reaching POST. The common culprits are loose or failed RAM (reseating or replacing a stick often fixes it, and many boards beep a pattern that tells us which), a loose graphics card, or a failing motherboard. We test the monitor and cable first, then the RAM and graphics, so we replace only the part that is actually dead.
Can you make my slow computer fast again without buying a new one?
Usually yes. On most older desktops the bottleneck is a mechanical hard drive. Cloning your Windows install onto a solid-state drive typically cuts boot and load times dramatically, and adding RAM helps if you keep many programs open at once. We clone your existing setup across so your files and programs come with you — no fresh reinstall needed.
My PC overheats and shuts off when gaming — is the processor fried?
Almost never. Sudden shutdowns under load are the system protecting a processor that is overheating because the heatsink is packed with dust and the thermal paste has dried out. We clean the cooling system, repaste the CPU (and graphics card if needed), and verify temperatures under load. A truly dead processor is rare.
Do you fix custom-built and gaming PCs, not just brand-name computers?
Yes — we service custom and self-built towers as readily as Dell, HP, and Lenovo machines. We can diagnose a build that will not post, swap a failed power supply or motherboard, and upgrade storage, RAM, or cooling.
