What to do? Wait and see if it does it again? It cant be the video card as I have just replaced that with a passive cooled GT610. Besides if the card went off it wouldn't show the Dell logo. This only shows on initial power up, otherwise it goes into sleep mode. I see on you tube there are a few videos replacing 1000uF caps on Dell monitor PSUs. Any ideas?
