process. These LEDs do not indicate the problem that caused the POST routine to stop. Note: Please be aware that if your system completes POST without stopping on a particular error code and then gives a black screen, the most likely reason is that you are experiencing a No Boot issue and not a No POST issue at all.

Posted by Davet50 on 2 Oct 2008 13:16 The beep code of 1-3-2 is 1-3-1 through 2-4-4 Memory not being properly identified or used I would suggest you remove all your memory sticks. Place one stick into Slot #1 http://en.community.dell.com/support-forums/desktop/f/3514/t/19204960 on the motherboard and see if the system will boot. Try this with each stick individuallyIf it passes with all sticks try placeing them all back in and test again HomeBuilt SandyBridge P8P67 i7 2600k @ 4.5 ghz 8gigs GSkill Ripjaws.

Posted by Davet50 on 2 Oct 2008 17:28 Well it could be that the motherboard is bad in that case.With no ram at all in the system it should give this beep code. If you tried all the sticks one at a time and still get the same error code it means either all the ram went or the motherboard has an issue HomeBuilt SandyBridge P8P67 i7 2600k @ 4.5 ghz 8gigs GSkill Ripjaws.

The diagnostic lights can appear either vertical or horizontal. Light Pattern Problem Description Suggested Resolution The computer is in a normal "off" condition, or a possible dell optiplex pre-BIOS failure has occurred. The diagnostic lights are not lit after the computer successfully boots to the operating system. Plug the computer into a working electrical outlet and press the power button. A possible BIOS failure has occurred; the computer is in the recovery mode. Run the BIOS Recovery utility, wait for recovery completion, and then restart the computer. A possible processor failure has occurred. Reinstall the dell optiplex 755 processor and restart the computer. Memory modules are detected, but a memory failure has occurred. If you have one memory module installed, reinstall it and restart the computer. (see Memory for instructions on how to remove and install memory modules.) If you have two or more memory modules installed, remove the modules, reinstall one module, and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error. If available, install properly working memory of the same type into your computer. If the problem persists, contact Dell (see Contacting Dell).
