Dell Inspiron 620--purchased 2012 has had problems from beginning with Power on. First, whilst still under warranty; it was the Power cord which was replaced. I have not used it, powered it on since September 2013. I just tried to power it on today==no response. I changed out the power cord--still no response. Tag on tower states it was manufactured 5/25/12. I purchased in July 2012. I have used it only 5 or 6 times. Is this particular tower known to be a Lemon? What else can I try? Warranty was up only 6 months ago...and the poor fellow is dead? Help?

SOURCE: Problems with Dell Inspiron 9400 Video Memory conflict -

This solution is totally incorrect. He is having the problem that many of us face with the GeForce Go 7900 GS and the Inspiron 9400. There is a known issue with eventual overheating and the video card going bad. This is specific to the single-pipeline chip, in which their is a new dual-pipeline style that fixes the cooling/overheating issue that eventually fries the video chip. Dell has not 100% took ownership of this. I am on my fourth fried video card (thank god for the 3-year warranty I got) in which they have previously replaced with the single-pipeline style. This time they are finally replacing the laptop with either a new Inspiron 9400 (better be dual-pipeline chip) or a NEW equivalent laptop.

I own & operate a computer reapair store. I recently worked on a Dimension 8400 that sounded like a jet taking off. I removed the heatsink, cleaned the heatsink & cpu, applied thermal grease & reattached the heat sink. It booted up quietly...after testing it several times...the turbo fan, jet engine sound returned! I removed the heatsink and along the upper part of the cpu I could see where the heatsink hadn't made contact with the cpu! I added more thermal grease & reattached the heatsink. It started fine on several attempts before the jet engine sound returned. I tried applying uppward pressure on the heatsink so it would close the apparent gap between the cpu & heatsink and when I pressed the power button...it started up quietly! At least I identified the source of the problem...not sure how to fix it yet.
