Tags: Dell Boot Dimension Computers Last response: July 25, 2008 7:54 PM in Computer Brands Share ozjason July 22, 2008 5:06:24 PM Hi Guys/Girls After updating my BiOS on my Dell Dimension 5150 will not boot up unless i have all the usb and lan connections removed. (issue only happend after upgrade) Now i get the orange flash of DEATH. And now this is the way i have to boot my PC. Remove all connections including power cable wait for orabge lite to stop flashing. Hold in power button replace power cable. ( This some times needs to be perfomred a few times) once the power goes green then i need to start plugging in everything like the usb and lan cables. I do not disconnect the DVI or the sound cable from the tower. If any one els has had this problem please help me out. And yes i did use the correct Dell BiOS upgrade and have all so downgraded the BiOS with still the same problem. And i was advised by Dell i would need a new Mainbored and i do not wish to buy a new mainbored or another pc.

Sounds like its trying to boot from flash and/or lan before hard disk. Make hard disk the first in the boot sequence. Can't find your answer ? Ask !
