According to this Dell troubleshooting page, your memory (RAM) modules are producing the error.

You should first remove and re-seat the modules to see if that will correct the error. This page will walk you through how to open your computer and how to remove and reinstall your RAM.

Since your computer is a few years old, check for oxidation on the contact points (the gold points where the RAM is inserted into the motherboard). If the contacts are not bright and shiny, take a pencil eraser and gently rub the contacts to remove any oxidation. Use a can of compressed air in short bursts and blow off any left over eraser shavings from the RAM module before you reinsert them.

If oxidation is not a problem, you may need to replace the RAM modules. I purchased this RAM for my 2400 a few years ago. Keeping in mind this RAM is a few generations old now, 1GB is the most effective size and price point for the RAM required. I am not affiliated with either Corsair or Newegg, but they are both excellent in what they do and I have used the site and products almost all my builds. Also, when installing RAM I try to use pairs so I have a little redundancy if one should fail.

Rear harness was bad they replaced with trailer harness and trying to fig out what yellow brown light green an dark green are on frame of truck it hooked in to so i can fix i un hooked not knowing what had...


Your description, I take it, is a problem with the wiring harness going from the driver's compartment to the rear lights. If that is the case, the normal color code for GM is brown for tail lights, dark green for the right stop & turn, yellow for the left stop & turn and light green for the backup lights. Any black wires should be grounded. The white wire in the trailer harness is for a ground when used on a trailer. It sounds like you have the green and yellow T&S wires shorted together somewhere! Some of the later vehicles use separate stop and turn bulbs... these would have a separate wire for the stop lights only, but I don't think your truck is new enough for that. Good luck!

My friend's PS3 has some light of death we are guessing! It will turn green, then will turn blue & green, then it turns green & yellow, then it turns blue & yellow. Then just yellow followed by...


This is known as the yellow light of death (ironic i know because it blinks a red light). This is caused when the unit overheats causing solder on the board to melt and bridge(connect). Once this happens it shorts out the board causing the error you have now. Contact Sony and see if the unit is still under warranty.
