Reliable PC & desktop repair in Stockport & Manchester
Is your desktop PC refusing to turn on, showing no display, running slowly or crashing? AC Computer Warehouse has been repairing desktop computers in Stockport since 2007. We fix no-power and no-display faults, failing hard drives and SSDs, RAM and graphics issues, power supplies, overheating, virus and malware infections, Windows problems and motherboard faults — on PCs of all makes, including custom and gaming builds.
Every repair starts with free diagnostics to pinpoint the real cause — rather than swapping parts at random — followed by a clear, fixed price before any work goes ahead. You get honest advice, a no-fix, no-fee approach on applicable repairs, and a workshop warranty on completed work. Whether it’s a slow office PC or a high-end gaming rig, we’ll get it running properly again.
Repairs, upgrades & custom builds
As well as fixing faults, we breathe new life into older desktops with SSD upgrades, extra RAM, graphics-card upgrades and clean Windows installs — often for far less than the cost of a new machine. We also build and upgrade custom and gaming PCs tailored to how you use them. Bring your PC into our Stockport workshop (free parking on site); we help home and business customers right across Greater Manchester and Cheshire, including:

What we fix
No power
If your PC is completely dead and shows no sign of life when you press the power button, we can help. We diagnose no-power faults properly to identify whether the issue is the power supply, motherboard, front panel controls or another internal component.
No display
If your PC powers on but nothing appears on the screen, we can help. We diagnose no-display faults to find whether the cause is the graphics card, RAM, motherboard, monitor connection or another hardware problem.
Windows repair
Stuck in a boot loop, crashing, freezing, very slow or failing to load Windows? We diagnose whether it is corrupted system files, failed updates, driver problems, software conflicts or another operating-system issue, then repair and test for stability.
Virus & malware removal
If your PC is behaving strangely, running slowly, showing unwanted pop-ups, redirecting your browser or triggering security warnings, it may be infected. We remove viruses and malware safely and secure the system afterwards.
Data recovery
If your PC has stopped booting, the hard drive or SSD has failed, or important files are no longer accessible, we diagnose the issue to determine the safest, most effective way to recover your data.
SSD & hard drive replacement
Slow to start, taking a long time to load programs, making unusual drive noises or failing to boot? The storage drive may be the cause. We fit reliable SSDs or drives and get the system running properly again.
RAM upgrades & replacement
Slow when multitasking, struggling with demanding programs, freezing unexpectedly or showing memory errors? The RAM may need upgrading or replacing — we advise what is suitable and fit it.
Power supply replacement
Not turning on, shutting down unexpectedly, restarting without warning or behaving unstably? The power supply may be the cause. We test and replace faulty supplies with suitable units.
Graphics card repair & replacement
No display, graphical glitches, crashing during gaming, freezing under load or poor video output? The graphics card may be the cause. We diagnose and repair or replace it.
Motherboard repair & replacement
Serious internal faults such as no power, no display, random shutdowns, failed ports or unstable behaviour often point to the motherboard. We diagnose properly and repair or replace where appropriate.
Overheating repair
Running hot, shutting down unexpectedly, unstable under load or constantly loud fans? We find the cause of the overheating and put it right to restore stable performance.
Fan replacement
If a PC fan is noisy, rattling, not spinning properly or has stopped working, we confirm whether it is the fan or another cooling problem and replace it to keep the system cool and quiet.
Custom PC upgrades
If your desktop needs better performance, more storage or improved reliability, we help with custom upgrades tailored to the way you use the machine.
