Question about Computers & Internet
You did not state the make and model of your computer so I can only recommend generic checks. When was the last time you ran disk defragmentation? A fragmented disk will slow down system operations. What operating system are you using and are you performing regular system updates? How much memory does the computer have? Windows XP SP1 ran well on 512Mb of memory, but after upgrading to SP3, you require at least 1Gb to run with any effeciency. How big is your hard drive and how much data free space is available? If your system is low on memory and your hard drive is almost full, paging (moving data from memory to hard drive and back to memory) is impacted, and will slow down the system. What speed Internet connection do you have? Dial up is much slower than broadband or DSL. Lastly, what browser are you using and do you regularily delete the temp internet files?
All of the above items will have a direct impact on your system operations. Also, make sure you are running a good antivirus program and perform regular scans. It is possible that you have a virus that is using your machine as a "zombie" and eating up your bandwidth sending spam.

SOURCE: power on failure
If the light you say is blinking on the back panel is actually on the power supply, and it's blinking, then your power supply is dead/dying and you'll need to replace it. I just fixed one of those a few weeks ago. They are rather cheap, as you can get them online for low prices. Try www.newegg.com.

The “self test” on the monitor displays when not plugged into a computer. This means that it’s working. The LED error code 2 and 4 means the video subsystem has a problem. Either your video card is bad or bad memory module. Try reseating video card and/or memory.
