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.
Most computer faults we see in Manchester sort into a few symptom families, and each points to a different fix — so we diagnose before quoting. A desktop or laptop that powers on with fans spinning but a black screen is a “no-POST” fault: we test in order — reseating the RAM, checking the power supply under load, then the motherboard itself — and on gaming towers a dead display with fans at full speed often traces to the graphics card rather than the board. A machine that has grown loud, hot, or shuts itself off mid-task is thermal: dust packs the heatsink fins and the factory thermal paste dries out after a few years, so a deep clean and re-paste brings temperatures and speed back. If Windows is stuck in an “Automatic Repair” or restart loop, the cause is often a failing hard drive rather than Windows itself — we pull your files first, then repair or reinstall, so a boot loop almost never means lost photos or documents. The single best upgrade for a slow but healthy older machine is cloning the spinning hard drive to a solid-state drive: same files, same programs, several times faster to boot and load. Cracked panels are their own jobs — laptop screens, ThinkPads, and external monitors — and Apple laptops go to our MacBook bench. Bring your computer to our Manchester shop; diagnostics are honest, your data stays on your drive, and most jobs are done while you wait.

Common questions
Before you come in
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.
Is my old desktop worth repairing, or should I just buy a new computer?
It depends on what failed, and we tell you honestly at the diagnosis stage. A dead power supply, a failing hard drive, or clogged cooling are cheap, high-payoff fixes — an older tower with an SSD upgrade often feels faster than a new budget machine, and you keep your installed programs and files. The math changes when the motherboard or processor itself has failed on a very old system, because those parts can approach replacement cost; in that case we say so and can instead recover your data and move it onto whatever machine you choose. You get the diagnosis and quote first, so you decide with real numbers, not guesswork.
My computer won't load Windows — it shows a blue screen or spinning dots that never finish. Are my files gone?
Usually not. A machine that powers on and reaches the maker logo but then can't start Windows almost always has a software or drive problem, not a wiped disk — your photos, documents, and installed programs are still sitting on the drive untouched even while Windows refuses to boot. The common causes are a corrupted Windows update or damaged system files, a bad driver installed just before it started failing, or a boot drive that is beginning to die (a mechanical drive clicking, or an SSD reporting SMART errors). Our first step is to image or copy the drive before any repair, so your data is safe even if the disk is failing, and then either repair the Windows install in place or — if the drive itself is dying — clone the recoverable files onto a healthy SSD, which also leaves the computer far faster. The STOP code on the blue screen often names the culprit, and we recover data first and quote the repair after diagnosis.
Is there a computer repair shop near me that does same-day, walk-in diagnosis?
Yes — bring your desktop, tower, or all-in-one in without an appointment, and in most cases we diagnose it the same day rather than holding it for a week. Counter-level faults — no power, a black screen at POST, or a machine that has slowed to a crawl — we can usually narrow down quickly, and you get the cause and a quote before any paid work starts, so you decide with real numbers first. The jobs that need longer are data recovery from a failing drive and board-level repairs, and we give you a realistic turnaround up front instead of leaving you guessing. If you are weighing up "computer repair near me," that diagnose-first, quote-before-we-start approach is what stops you paying for a part that was never the problem.
