Diagnosis of Dell Desktop?

I have a Dell Optiplex GX 260, which seems to be playing a new code problem to me every day. I just tried 3 times in a row and seems to give me a beep code 4-2-2. In the ABCD lights on the rear panel, A, B and C and D are green is yellow / orange. Any advice or ideas? Thanks people! Yes, Dell has always had a bad reputation for making computers so that you can not upgrade without going through them and pay their prices ridiculous. Shady business. The moment you pay out your a $ s for your hardware / software, you might as well buy another computer. It does not take long before computers become more obsolete in this day and age, and Dell, which used to be of about 10 years ago, are nothing but trash when it comes to desktops. Nothing against the representatives here who try to help you and perhaps represent a Dell, but I do not think I will never buy a Dell or an HP never !!!!!!!!

The Post Beep Code 4-2-2 states The Lights Shutdown failure to diagnose or A, B and C Green – D Yellow / Amber reflects an error code / description on its video screen by Manual. Hmmm try to answer this question if these results and explanations do not seem to be very useful. What can be said definitely is a problem with the computer and is a hardware problem. This will cost money to fix a guess and say it's either: Memory – Low possibility Processor – Medium Possibility Mother – Greatest next possibility is to consider that an Optiplex GX260 is an older PC and how much you're willing to pay to get it fixed or perhaps take this money (and a little more) to get a new PC. monitor, should also be used with a new PC, however, the GX260 original mouse and keyboard are PS2 and use New USB PC so that they (keyboard and mouse) must be replaced. Dell regularly has sales and if you have the software for the GX260 you should be able to load it on a New Dell however, you need to download and install the appropriate drivers. Anyway, this is my thinking on this issue. I hope this helps!
