Practical Computer Guides From PCRuns
Understand the problem, protect what matters, and make a better-informed decision before repairing, upgrading, or replacing a computer.
The PCRuns Knowledge Center provides plain-language guidance for Windows computer users, homeowners, and small businesses. These guides explain common problems, safer troubleshooting practices, storage and memory upgrades, drive cloning, file recovery, backup planning, and the questions worth asking before paying for service.
I’m John Zettel, the owner and sole technician at PCRuns. The material here reflects the practical issues I encounter while helping Milwaukee-area customers, while recognizing that every computer and data-loss situation is different.
If a drive is clicking, disappearing, or repeatedly failing, stop using it. Continued operation can reduce the chance of recovering important files.
Start With the Guide That Matches Your Situation
Computer Upgrades
Learn when an SSD, NVMe drive, memory upgrade, or Windows 11 transition can improve an existing computer—and when replacement may offer better value.
Drive Cloning
Understand how cloning works, when it is appropriate, what can go wrong, and how a complete drive copy can support an upgrade or migration.
Data Recovery and Backup
Learn how different types of data loss occur, which first steps are safest, and how backups can reduce the consequences of deletion or drive failure.
Computer Repair Costs
See which factors affect repair expense, including diagnosis, labor, parts, computer design, data risk, and whether additional problems are discovered.
Repair or Replace?
Compare the computer’s age, condition, usefulness, compatibility, likely repair cost, and the price of a suitable replacement.
Choosing a Repair Technician
Know what to ask about evaluation, authorization, data protection, replacement parts, workmanship, communication, and unexpected costs.
Protect Important Files Before Attempting a Repair
When a computer becomes unstable, the first priority is not always making it start again. If important files exist in only one place, consider their condition before running repair utilities, reinstalling Windows, resetting the computer, formatting storage, or repeatedly restarting a failing drive.
A troubleshooting step that is reasonable for a healthy computer may be risky when storage is physically failing. If the files are irreplaceable or the drive makes unusual mechanical sounds, professional data-recovery evaluation may be safer than do-it-yourself experimentation.
Upgrade and Windows Guides
Windows 11 Upgrade Planning
Review compatibility, backups, storage, memory, and a practical upgrade sequence before making a major operating-system change.
NVMe Versus SATA SSD
Compare real-world responsiveness, large-file performance, compatibility, capacity, and cost without relying only on advertised benchmark speeds.
How Much Memory Do You Need?
Learn how RAM affects browser tabs, multitasking, applications, and overall responsiveness—and why more memory does not solve every slowdown.
Drive Cloning and Boot Guides
Cloning With AOMEI Partition Assistant
Follow a step-by-step workflow for copying a compatible source drive while paying attention to destination selection, capacity, boot configuration, and verification.
USB Cloning With Macrium Reflect
Learn how rescue media and an external connection can be used in a cloning workflow, along with the checks needed before relying on the new drive.
When a Cloned Drive Will Not Boot
Review common causes involving UEFI, legacy boot mode, boot records, partitions, storage drivers, BIOS settings, and the cloning process itself.
Boot Menu Keys and USB Startup
Find common startup-menu keys for HP, Dell, Lenovo, and other manufacturers and learn why the correct key can vary by model.
File Recovery Guides
Accidentally Deleted OneDrive Files
Learn from a real synchronization-related deletion incident and the recovery options that may remain available.
Recover Deleted OneDrive Files
Check the OneDrive recycle bin, version history, Microsoft recovery options, and connected devices before assuming cloud files are gone.
Computer Will Not Start
Understand ways files may be accessed or copied even when Windows or the computer itself will not start normally.
Failing Hard Drive
Recognize warning signs and understand why repeated scans, restarts, or repair attempts may worsen a physical failure.
External Hard Drive
Separate cable, power, enclosure, file-system, Windows, and drive-related possibilities while protecting the data.
SSD Recovery
Learn why SSD recovery differs from hard-drive recovery and how TRIM, controller failure, encryption, and backups can affect the options.
USB Drives and Memory Cards
Review safer first steps for removable media used in cameras, phones, recorders, and computers.
Use These Guides as Education, Not a Diagnosis
Computer symptoms often have more than one possible cause. A slow computer may have a storage problem, insufficient memory, overheating, unwanted software, Windows trouble, or several issues at once. A computer that will not start may have a power, display, memory, storage, operating-system, or motherboard problem.
The guides explain useful principles and common possibilities, but they cannot determine the condition of a particular computer without examining it. Back up important files before making changes whenever possible, and stop if a procedure produces unexpected results.
Not Sure Which Guide Matches Your Problem?
Tell me what the computer is doing, when the problem began, and whether important files may be at risk. I will help you identify the most sensible next step.
