DFI LanParty Ultra-D UT

System was stable before I touched anything. I got a good deal on some Adata Vitesta DDR 400 (2x1GB) identical to what was in my system. I added the new memory, so 4x1GB Adata Vitesta DDR 400 is what is has now. XP Pro SP3 started up fine, I restarted and now it will not even post and hangs with 2 diagnostic LED's lit, not recognizing my vga card. I reverted back to just the 2 original sticks and the same thing happens, I even removed 1 stick. I am having the same problem on a DFI RDX-200. Has anyone experienced this before?

 

First check that you did not bump a cable loose in your computer, make sure your video card is seated properly, also make sure you are installing the RAM properly. You say you have diagnostic lights, what code is it giving you and do you have your manual to see what it is? If you don't, post what code you are getting and we can google around and see if we can find it.

 

good to go, bumped a molex to my dvd drive...thanks man!

 

Always nice when a simple fix is found! :-D

 

lol...not to mention my old DFI RDX-200 had the same problem. I dont know how I missed that, but I run two IDE optical drives in my systems and only had 1 of them powered up...DOH!

 

It happens. I used to wonder why my old computer would not boot after I moved it. Turns out when I moved it I turned the PSU off! :-D
