We repair Windows laptops and desktops from HP, Dell, Lenovo, ASUS, Acer, MSI, and others, plus custom gaming PCs. Typical jobs: a computer that won't start or shows no display, crashes and blue screens, overheating, viruses and pop-ups, and older laptops that need an SSD or more RAM to feel fast again. Give us a budget and we'll also spec and build a new PC. The diagnosis is free, the work is done in Tamuning, and repairs carry a 90-day warranty.

PC & Laptop Repair: common questions

Do you fix slow computers and remove viruses?
Yes, it's one of our most common jobs. We find the cause with a free diagnosis, clean up and tune the system, and only recommend upgrades that will genuinely help.
Can you build a custom gaming PC on Guam?
Yes. Tell us your budget and what you play or work on, and we'll spec, source, and build the PC, then set up Windows and your software. Builds usually take 2–5 days.
My PC won't turn on or has no display. Can you help?
Yes. No-power and no-display problems can come from the power supply, RAM, graphics card, storage, or motherboard. The free diagnosis finds which one before we quote.
Can you upgrade my laptop with an SSD or more RAM?
On laptops that allow it, yes, and an SSD is usually the single biggest speed-up for an older machine. We'll confirm what your model supports.

Not sure what's wrong? We'll find out for free.
