I bought a new computer and moved my XPS 410 to another room in my home. I noticed a lot of dust on the grids, lower front so, stupidly, I quickly brushed it away with a soft brush. A lot came into the room. When I turned the computer on it would not go completely through the bios to windows. I removed the cover and blew out the dust hoping it was the problem. Immediately after that it did boot fully; all seemed well. The next day I attempted to turn it on again; just part way through bios again. I bought a can of compressed air from Office Max - they said I could use it inside the box but warned against turning it upside down. I was careful about that. After closing the box it did, once again, boot up; all seemed well again. Actually I was able to get it to boot several days but it would give me the 'silent treatment' intermittently. Yesterday I could not get it to go beyond that usual point in the bios. The lights on the front usually showed 1,2,&3 - green. But once it showed the 3 & 4 green lights only and my manual says the memory modules are detected but a memory failure has occured. I first re-seated both memory sticks. This did not help. I then removed one. No help. They not being easy to replace I decided to put it back, make sure both were securely locked in place, try to turn it on and if nothing happened different to seek help elsewhere.
I must add: during my frustrating attempts those light patterns changed often; I have mentioned the most often shown. And I have reseated all the inside cables I could do easily. All of this has been over the course of about one week as I moved the computer on the 14th of June.
Any and all suggestions will be appreciated.
This is Bessie again. I stumbled on the answer: When getting ready to take my tower to a computer store to have it 'fixed' I sat it on my kitchen table. Then I decided to try it just one more time - went and got the monitor and mouse, plugged them in and pushed the button on the tower. It booted normally! So I decided it must have not been getting enough ventilation where I had it so I removed the printer and set the tower so it would have lots of venting. It booted up just fine. Then one day I decided to move something else from the credenza and made room for the printer. Plugged it in and my old problem came back! I was about ready to throw the printer in the garbage can at that point. But I removed it and my computer continues to boot just fine. I did try the printer connected to another, older Dell computer I have and much to my surprise it booted just fine. So I will just give that Dell Printer to someone else along with the older (Dim 8400) computer someday. In the meantime I will continue to use my older HP printer! Funny though. That Dell printer was purchased along with the XPS 410. Guess I am still scratching my head on all of this!
