COMPUTER MAKE STRANGE NOISE If your computer suddenly starts to buzz or vibrate, it can be due to a hardware failure. High, whining noises may indicate problems with the electrical components, while buzzing noises are often caused by lack of ventilation. Tip: Clean the filter and fan for dust and make sure that all air inlets are free. If you have a laptop, you can try to uninstall and reinstall your sound drivers. If it is a desktop, it may be that the sound card needs replacement.

CANNOT  GET ONLINE         Internet connection problems can be caused by many different things. The most common are network misconfigurations, hardware or software errors in the router, latency from your Internet Service Provider, incorrect IP address configuration, incorrect connection of network cables, firewall applications that block http traffic from your PC or temporary timeouts your ISP. Tips: Check that the Wi-Fi is enabled on your computer - laptops often have a button, switch or Function key combination somewhere on your computer or keyboard. Check that the network icon on your computer is connected or if there is a yellow warning signal or it is disabled. If it is connected, call your network provider or get hold on someone with more knowledge on IT. If Wi-Fi is disabled, you must check whether the cable is connected properly or if wifi is not on. If there is a yellow warning, you must reboot the router. If this does not work, try pressing Sta...

Not Enough Memory – Check your Memory and Improve Your PC Performance It’s important to have enough memory on your computer to keep your programs running smoothly. If you have large programs such as PhotoShop, or if you play a lot of games on your computer, it is recommended that you have at least 512MB on your PC. At this point, 1024MB (or 1GB) seems to be the sweet spot and adding more RAM doesn’t appear to be cost effective for most users. The amount of RAM your PC has can be checked by right-clicking My Computer and choosing Properties . If you need to upgrade your RAM, be sure to check your local retail ads for sales. You can usually get a RAM upgrade to improve PC performance at a great price.

MISSING DLL FILE Dynamic-Link Library (DLL) files house information for your operating system on how to perform certain functions. Occasionally, your computer loses DLL files or something damages them. When your PC can't read the particular DLL file, it doesn't know how to respond in certain situations. You may have a missing or corrupt DLL file if you receive an error message every time you perform a certain function, such as saving. If your computer problems are stemming from missing and damaged DLL files, you can restore them by downloading them back onto your PC.

CANNOT OPEN EMAIL ATTACHMENT If you have ever encountered an attachment that you couldn’t open, it was probably because you didn’t have the software necessary to view the file. If you don’t have Adobe Reader or another PDF-compatible program, you won’t be able to open that TPS report. The usual suspect is the .pdf file, for which you can download a free PDF reader. If your problem involves a different file format, a quick search on the attachment’s file extension (the three letters after the period in the filename) should tell you what type of program you need. If the attachment lacks a file extension (which might happen if it was renamed), adding it back should set things right.

 Wi-Fi keeps disconnecting Spotty wireless connections can be a puzzler. Is it your computer? Your router? Your ISP? Try a few things before calling your Internet service provider. Windows Network Diagnostics may not always solve your problem, but it will usually point you in the right direction. Confirm that your computer is within range of your wireless router. Weak signals mean weak connections. Next, make sure your PC’s wireless card has the latest drivers. Try letting Windows troubleshoot for you by right-clicking the Wi-Fi icon in the taskbar and selecting  Troubleshoot problems .
