How to Run a Diagnostic on Your PC

When your computer starts acting up, running a diagnostic can save the day. Here are some easy ways to sort out what\’s wrong with your PC, step by step:

  1. Windows Troubleshooter
    • If you\’re on Windows 11, just hop over to Settings, click on System, then Troubleshoot, and go for “Other troubleshooters.” It’ll help you check things like Bluetooth, Keyboard, and even your network connection.
    • For Windows 10 users, head into Settings, hit Update & Security, and find Troubleshoot. Pick the one that fits your problem from the list.
      These built-in troubleshooters are like the little elves of Windows—they work behind the scenes to fix settings without you lifting a finger.
  2. Windows Memory Diagnostic
    • Here\’s a quick tip: hit Windows + R and type “mdsched.exe” to fire up the Memory Diagnostic tool.
    • Go ahead and select “Restart now and check for problems” or leave it for the next boot. It’ll check your RAM for hiccups.
    • Once your PC is back, pop open Event Viewer, check Windows Logs, and look for “MemoryDiagnostic” to see what’s what.
      This tool is a lifesaver if you\’ve got a sneaky RAM issue that\’s slowing everything down.
  3. Performance Monitor and Reliability Monitor
    • Want the lowdown on what your PC\’s been up to? Open Performance Monitor from the Start menu for detailed graphs on CPU, memory, and more.
    • Check out Reliability Monitor and its history of software hiccups and hardware errors.
      These tools are like looking at your PC’s diary—they show you trends that might hint at what\’s causing any performance blues.

You might have some extra goodies from your PC\’s maker:

  • HP PC Hardware Diagnostics: Many HP computers come with tools right under Windows or UEFI (outside of Windows) to check out your CPU, memory, and storage. The UEFI version is brilliant for diagnosing without the OS getting in the way.
  • Dell and others might have something similar, so check your user manual or jump onto the manufacturer\’s website to see what\’s on offer.

Want to dig deeper? These third-party tools have got you covered:

  1. MemTest86+
    • A favorite among techies for checking RAM issues with more detail than the Windows tool.
    • You can boot it from a USB drive and it supports all kinds of memory. Plus, it comes with an easy-to-use interface.
  2. CrystalDiskInfo
    • This one helps you keep tabs on your hard drive or SSD health using SMART data.
    • It\’s like your own little drive health monitor—catching those nasty issues before they lead to data losses.
  3. HWiNFO
    • An all-around system monitor that keeps tabs on pretty much every piece of hardware in your PC.
    • Super handy for noticing odd temperatures or voltages that could be a sign of trouble brewing.
  • Battery Health (for laptops):
    Give your battery a check-up too—just run Command Prompt as an admin and enter “powercfg /batteryreport” to get the full scoop.
  • Bootable Diagnostic Utilities:
    Tools like PartedMagic or the Ultimate Boot CD can be run straight from a USB drive or CD/DVD. They’re great for separating hardware issues from software ones.

By diving into these tips, you’ll be on your way to diagnosing your PC like a pro. Whether it\’s a faulty video card or a need for a full system upgrade, figuring out the problem has never been easier.

How to Run a Diagnostic on Your PC: A Handy Guide

Every now and then, your computer might throw a hissy fit with a random crash or slowdown. Before you panic, running some diagnostics could help pinpoint what\’s acting up. Let\’s dive into a mix of built-in tools and some neat tricks to sniff out those issues.

1. Using Windows\’ Built-in Diagnostic Tools

Windows already has a few trusty sidekicks for troubleshooting. They\’re there to keep your PC in check and fix up any weirdness.

A. Windows Memory Diagnostic

  • Why Do It?: Checks if your RAM is the culprit behind crashes or those dreaded blue screens.
  • How To:
    1. Hit Win + R, type mdsched.exe, and press Enter.
    2. Select \”Restart now and check for problems\”
    3. Your PC will reboot, running the memory test automatically.
  • If Errors Pop Up:
    • Try reseating the RAM or swap out faulty sticks.
    • Check each RAM stick in different slots to figure out which one\’s wonky.

B. Check Disk (CHKDSK)

  • Why Do It?: Fixes errors on your hard drive, such as corrupted files or bad sectors.
  • How To:
    1. Open Command Prompt as Administrator.
    2. Enter chkdsk C: /f /r (swap that \”C\” with the problematic drive\’s letter).
    3. Agree to run it on the next reboot.
  • If Bad Sectors Are Found:
    • Back up your data pronto.
    • If issues persist, it might be time for a new drive.

C. System File Checker (SFC) and DISM

  • Why Do It?: On a mission to chase down and fix corrupt system files.
  • How To:
    1. Run sfc /scannow in Command Prompt (Admin).
    2. If things still seem off, try: DISM /Online /Cleanup-Image /RestoreHealth
    3. Reboot and run SFC again for good measure.
  • If Corruption Sticks Around:
    • Consider doing a repair install or resetting the OS.

2. Getting a Little Help from Third-Party Software

There are specialized tools for when you have to dig a bit deeper, especially if you love stats and real-time monitoring.

A. Hardware-Specific Tools

  • MemTest86: Does a deep dive into your RAM\’s health.
  • CrystalDiskInfo: Checks on your SSD/HDD’s well-being.
  • HWMonitor: Keeps an eye on your CPU/GPU temps.

B. Stress Testing

  • Prime95 (for CPU) and FurMark (for GPU): Take these for a spin to see how your components handle pressure.
    • Game Plan: Run these for about 30–60 minutes to see if anything overheats or crashes.
  • If Things Get Too Hot:
    • Give your fans and heatsinks a good dust-off.
    • Reapply thermal paste or consider better cooling solutions.

3. BIOS/UEFI Diagnostics

Your BIOS/UEFI isn\’t just for show. It can actually tell you if something\’s up with your hardware.

  • How To:
    1. Restart and hit the BIOS key (often F2 or Delete).
    2. Find the Hardware Diagnostics section for insights on your CPU, drives, etc.
    3. Take note of any red flags.
  • If BIOS Shows Errors:
    • Update your BIOS firmware as per the manufacturer\’s instructions.
    • Reset everything to default settings, just in case.

4. Ratting Out Common Troublemakers

A. Boot Failures

  • What Might Be Going Wrong:
    • Bad bootloader, a failing drive, or hardware that just isn’t playing nice.
  • Fixing It:
    • Use the Windows Recovery Environment (WinRE) to mend the boot records.
    • Strip down your setup to the bare essentials (unplug any extras) and see if it boots.

B. When Your PC Gets Sluggish

  • What Might Be Going Wrong:
    • Malware, programs clinging to your memory for dear life, or fragmented disks.
  • Fixing It:
    • Run a full antivirus check with tools like Windows Defender or Malwarebytes.
    • Fire up Task Manager and cut down on the junk starting up with Windows.

C. Battle of Blue Screens of Death (BSOD)

    • Conflicting drivers, hardware misbehaving, or leaks in memory usage.
  • Fixing It:
    • Dig into the error codes with WinDbg or BlueScreenView.
    • Roll back troublesome drivers or consider a fresh OS start.

5. Exploring Advanced Diagnostics

A. Event Viewer Logs

  • Why Bother?: View logs to catch any repetitive errors tripping your system.
  • How To:
    1. Press Win + X and open Event Viewer.
    2. Drill down to Windows Logs > System and filter for Critical/Error.

B. Having a Clean Boot

  • Why Bother?: Weed out conflicting software without the fuss.
  • How To:
    1. Open System Configuration (msconfig).
    2. Under Services, check \”Hide all Microsoft services\” and disable the rest.
    3. Enable services one by one after a restart to sniff out the troublemaker.

6. When to Call in the Pros

  • If hardware keeps flaking out—like repeated hard drive errors—or you’re dealing with motherboard or GPU issues best left to someone with all the right tools.
  • And for critical data loss, definitely rope in a recovery service!

By tooling around with these steps, you\’ll get a good sense of what\’s wrong with your PC without too much hassle. But remember, before you dive in headfirst, back up all your precious data. Better safe than sorry, right?
