Gigiya Posted March 28, 2007 Posted March 28, 2007 I sure was glad to see this forum when I googled "DFI Diagnostic LED." I really need some help. About a week ago I decided to blow out the inside of my case since I hadn't in awhile. I did so. I brought my PC back inside, hooked it up, tried booting up, and the power LED blinked. Turned it off and on a few times, it booted up, and everything was fine. I had ordered a new monitor with the money from my tax return, so I turned my PC off to hook it up. Booted back up, got the same flashing LED error. The computer eventually didn't turn on (I'm an idiot and didn't notice this until today - I had pushed the actual button in through the case somehow, hence the power button doing nothing. I have since fixed that), so I figured the PSU was at fault. Ordered a new one, the one listed in my sig, and got it today. Installed it before work, turned it on (this was when I realized the power button being pushed into the case) with the power button on the mobo, and much to my dismay the power LED started flashing. Checked the diagnostic LEDs and saw three of them were on. I had googled this the week before and saw only that three LEDs meant the CPU had been detected. I guess I had searched something slightly different then; today I found this site and the expanded info that three LEDs meant the CPU was detected but there was a problem with the RAM. I tried switching out my four sticks of RAM. Eventually, trying one of the cheaper Valueselect sticks in either Slot 1 or 3, I can't remember since I was in a hurry before work. My machine actually went into the BIOS at this point, and told me to either put one stick in Slot 2 or the dual channel sticks in slots 2 and 4. Did so (ultimately again with all different variations), went back to the three diagnostic LED error. Can't duplicate the result of it going into BIOS now. I'm at a loss. I can't think of it being anything besides the mobo being bad. Clearly it's important for me to test my RAM in another system but I can't do that at the moment; with the spottiness of any RAM being detected I doubt that's the problem - how would four sticks simultaneously go bad? Any and all help would be greatly appreciated. Quote Share this post Link to post Share on other sites More sharing options...
Gigiya Posted March 29, 2007 Posted March 29, 2007 Tried full CMOS clear as instructed in the walkthrough in someone's sig. Eight hours. Didn't work. I'd REALLY appreciate some help here; not sure whether to replace my mobo or replace my PSU. Quote Share this post Link to post Share on other sites More sharing options...
Gigiya Posted March 29, 2007 Posted March 29, 2007 I took the mobo out of the case and set it up with just the vid card and hard drive and two of the 512 sticks (the decent Corsair ones). It POSTs, can access BIOS, Windows logo displays properly, then when it tries to start Windows I get a distorted image on the screen that does not change at all.

Gigiya Posted March 29, 2007 Posted March 29, 2007 Ordered a new identical mobo, nevermind Quote Share this post Link to post Share on other sites More sharing options...
