Computer Troubleshooting and Diagnostics

Peter's PC Repair323-412-0433

Having trouble with your computer? We've been there too. Maybe you've just built a new PC that won't power on, or perhaps your reliable machine has started showing the dreaded blue screen of death (BSOD). It could be random shutdowns, system crashes during important work, or hardware that's acting up - like a laptop keyboard with missing keystrokes or a trackpad that has a mind of its own.

Screen issues can be particularly frustrating - whether it's strange glitches, color distortion, flickering, or those mysterious blocks that appear out of nowhere. These visual problems often signal underlying issues that need professional attention.

When your computer is misbehaving, we're here to help. You might have a hunch about what's wrong but lack the specialized tools or replacement parts to confirm it. Or maybe you're completely stumped and just want your computer working properly again without the crashes, freezes, or error messages interrupting your day.

What helps us solve your problem faster is knowing the details. When exactly does your computer crash? Does the BSOD appear during specific programs? Are those random shutdowns happening during gaming or video streaming? The more you can tell us about when instability occurs, the better we can target the root cause - whether it's overheating, driver conflicts, memory errors, or hardware failures.

With over 18 years diagnosing everything from simple fixes to complex technical mysteries, we've developed a knack for computer troubleshooting. While we can't promise to solve every possible problem (some computers really do reach their end of life), we'll put our best detective work into finding what's causing your system instability and recommend the most practical solution to get you back up and running.

Contact us today about your computer troubles - whether it's sudden crashes, slow performance, boot failures, or strange noises coming from your machine. We speak both tech and human, so don't worry about knowing the exact terminology. Just tell us what's happening, and we'll take it from there.

Already tried fixing it yourself?

If you’ve been working through a guide, forum thread, or an AI chat and the problem keeps coming back, tell us what you’ve already tried. Include the computer model, exact error message, and whether the problem happens at startup, during a particular program, or only under load.

A suggested diagnosis is a starting point. Testing can help distinguish a software problem from faulty memory, a failing drive, or another hardware issue. The examples below show the kind of evidence we look for. Bring your notes or a short summary so we can pick up where you left off.

Memory Testing and RAM Problems

Faulty RAM can cause blue screen of death (BSOD) errors that start out intermittently and become more frequent over time. If your computer is crashing more and more often, we can test the memory as part of tracking down the cause. In the example shown here, the test reported so many errors that it stopped.

Graphics Problems and Screen Glitches

Display artifacts are visual glitches such as unexpected lines, blocks, or corrupted text. Stripes across the screen, strange blocks of color, or text that's suddenly become unreadable? The computer shown here is displaying graphical corruption before Windows has loaded. When the problem appears helps us decide what to investigate, so tell us whether you see it at startup, only in certain programs, or while gaming.

Windows Startup Errors

Maybe your PC won't get past the Windows logo, keeps dropping back into Startup Repair, or stops with a blue screen of death (BSOD) before you can log in. Boot failures and startup repair loops can follow a failed Windows update, drive corruption, or a failing hard drive or SSD. Faulty RAM, a graphics card problem, and other hardware faults can also be responsible.

We can investigate both Windows and the hardware to find out why your computer won't boot. Tell us what happened before the trouble started, whether it fails the same way each time, and any error message or stop code you've seen.
