I have (actually my wifes has) a Dell Inspiron 2500 laptop. 800mhz proc., 512 mem, 20 gig HD. About 2 months ago, it kinda just stopped working. All 3 lights would come on HD, power, and battery, but it would not go past this. I went on the net, and one forum suggested re-seating the memory sticks. I did that, ad viola, it started working again. Then again in about 3 days it stopped working again. This time re-seating memory did not do the trick. On occasion it would go to a point of a very garbled screen, and I could tell it was booting. So I plugged a monitor into the back, and could see Windows XP was up and running. Hmm, so I let it run for my wife like this, but after 2 or 3 days it stopped working again. Now here is the strange part, I had been pretty busy, but today I was down in my workshop, and decided to plug it back in and see what would happen. OMG it booted up normally. I took it upstairs to show my wife, and rebooted it, and again nothing but the 3 lights, no booting. I don't get a beep code with the memory out, I will try to find out what that means, but does anyone have an idea of what this could be, and why it came on normally after sitting 2 months?
