I have an older Gateway computer. When I turn it on, it goes to the Microsoft screen and you can see it loading, then it goes to the user screen. But lately it gets stuck on the Microsoft screen. You can see the line going across, and across, but it never changes. Eventually, if it finally loads, I end up leaving my computer on because I am afraid it’s not going to start next time. What kinds of things can cause this?
Windows Slow Startup
I don’t blame you for leaving your computer running. After all, who has the free time to wait for Windows to load? However, something is going wrong somewhere. Let’s take a look at some of the more common causes behind slow startup times.
Causes for Slow Startup Times
Many culprits can be to blame including a fragmented hard drive, a nearly full hard drive, excessive startup programs, a bloated Windows registry, spyware and viruses, and failing hardware. Your computer could have a combination of these errors.
Disk Cleanup and Defragmenter
Since your computer is currently running, let’s first do some basic maintenance by cleaning up the hard drive and defragging it. Your computer needs a certain amount of free disk space in order to function, so this is a good place to start. First, double-click on My Computer and look at the C:\ drive. Is it nearly full? If so, then that’s not helping matters. Right-click the C:\ drive and choose Properties. Click Disk Cleanup and clear up as much space as possible.
Once the drive has been cleaned up, use the Disk Defragmenter utility to defrag it. This article describes this tool:
Excessive Startup Programs
Another common contributor to startup issues is having too many programs loading up at boot up. It’s hard enough for Windows to load itself let alone all those extra computer programs. This article describes how to manage startup programs in detail:
Bloated Windows Registry
The Windows registry is a huge index containing nearly all of the instructions that Windows needs in order to work with the computer’s installed components. It is constantly growing as new programs are installed, old ones removed, new hardware added, user settings changed, and so on. Unfortunately, when it gets too large, computer performance suffers. Plus, many of the instructions end up becoming obsolete or even damaged.
For example, what if you’ve since uninstalled a program, but the uninstallation didn’t complete successfully? Partial instructions could be left behind. When Windows starts up and receives those instructions, it tries its best to carry them out but since the program has been partially installed, it can’t find what it needs in order to carry out the mission. Windows may get stuck, generate an error, or work slowly as it goes through a series of unnecessary steps.
Because your computer is having major startup problems, I highly recommend a good registry cleaning. The article, Why Use a Registry Cleaning Tool, explains registry issues in greater detail.
Spyware and Viruses
Spyware and computer viruses are notorious for damaging system files and interfering with performance. If you have a reputable antivirus product on your computer, update it and run a full system scan. If you’re unsure about the reliability of your product, any of the following free tools would be a good place to start.
- Microsoft Malicious Software Removal Tool
- BitDefender Scan Online
- Trend Micro House Call
- McAfee Free Scan
Failing Hardware
Finally, failing hardware can lead to slow start times. A qualified computer technician can diagnose your hardware to see if any of the computer’s components is failing. If your computer continues having startup issues after freeing disk space, removing startup items, cleaning the registry, and removing malware, then it’s time to let a professional take a look.

Sometimes, one of the most difficult events to avoid is the long-desired upgrade that turns into a disaster. How many times have I tried to improve upon my existing computer set up and run into minor dilemmas? More than I would like to say. However, the good news happens to be that almost every problem has a solution. I just need to persevere and follow each of the troubleshooting steps until I locate the correct one for the situation.
