Because several readers come up with their computer reacting slowly, I’m submitting a summary checklist of general steps you can take to solve the 0x0040fd90problem, and briefly discussing the three most frequent causes : malware, uncontrolled applications, and insufficient care.
Malware
Perhaps the most important contributor to a badly performing computer is malware. Generally this is associated with downloading an application that includes spyware, by not having browser security options large enough, by carelessly downloading P2P files, or by failing to install security areas regularly.
Action 1. Update the explanations of your antivirus and run a full scan of your hard disk drive in Safe Mode. Resolve any unfixable problems. Notice that some viruses require extra steps until they could be removed; normally a internet search will find specific directions or a particular removal tool. If you fail to find a answer, use the Bc forums to request support.
Step Two. You have recently saved an application, and if the slowness is sudden, the issue may reside there. Check this by fully removing it. A user will typically perform a websearch about the program before installing because in most instances, any possible difficulty with malware or inferior performance will have appeared.
Step three. Adware and Spyware can radically effect your computer’s operation, and these are around the Web. A very recent study showed that one out of every 20 executable files on Websites is spyware, and 1 in 25 domains comprise at least one piece of spyware waiting for sufferers.
Revise the definitions of your anti-spyware applications and scan your hard drives in Safe Mode. Experienced customers will often run 2 or 3 of these programs, because each business has its own requirements for what constitutes spyware and will simply search against their own established. (A listing of quite good, free antispyware applications is given by BC). Again, solve any open issues before proceeding to the next phase.
For additional reading about Malware and some malware removal applications, use BC’s Tutorial section; most of the programs have quite good Help documents that describe how they function as well as the special characteristics of each.
Uncontrolled Applications
Step 4. Evaluation applications that self-launching on startup. You pc can be a battleground for your attention. Many programs, for example, install a fast-launch feature that enables them to be exposed immediately; other programs will include an automatic update feature that requires them to be operating in the background. Your launching Windows are slowed down by each of these and each requires a small bit of resources while your computer is running.
Remember that Bc maintains a quite complete Startup Database that contains information about whether the item is needed, discretionary, or unnecessary, if you are uncertain about what may be safely deleted.
At the same time, remember that those icons in your Desktop also take a small amount of trunk time to set themselves.
Lack of Upkeep
Stage 5. Delete unused applications and exchange old files into a CD. Unplayed games, lots of family pictures, zipped files which you have previously opened, applications you haven’t found in two years, software for the old printer you threw away last year—these are a few types of files you can delete.
(Note for sophisticated users: some professionals would contain the additional upkeep step of cleaning the Windows registry, and you’ll find several applications to help do this. For the most part, so this step isn’t contained, you may do serious damage by creating registry modifications, registry maintenance won’t make a significant difference, and unless you’re quite comfy with Windows, and cautiously make backups of the registry
Step 6. Run scandisk / checkdisk in Safe Mode. Have it mend 0x0040fd90.
Step 7. Defragment your computer. Windows tends to set new documents in any available open space; defragging will place affiliated segments of files closer together therefore your read arm has less travelling around the hdd to do, saving wear and tear while racing up applications.
Hopefully, since you have have concluded, you’ll see a marked enhancement in computer functionality.
