XPS 420 will not boot, fans on high

I tried to power on the computer the other day and it would not boot. THe power button on the front of the case is blue, indicator lights 1, 3, and 4 stay on. The hard drive indicator is solid for about 5 seconds then turns off. The fans remain on high. Sometimes if I am lucky the monitor will turn on, but then will shut off. I have recently switched out mother boards to a refurbished Dell, switched out the memory and have disconnected and reconnected everything in the case. Please advise. Desperation is starting....

Thanks

Starting to track this down. I have pulled everything off the motherboard. With just the motherboard with power, CPU. All cards are out, all RAM is out, hard drive disconnected, front panel has power.

1) I am getting a blue power button on the front of the case, indicator light 1 only, the miniview on the case is displaying "No memory modules detected".

2) Added 1 gig of new Dell memory, not the same memory that came with the computer. Getting indicator lights 1, 2, and 3. Power button onfront of case is still blue. Miniview display shows "Card case fan failure"; "CPU fan Failure", "System Battery Voltage is low", and "No Display device found".

3) Connected what I now know are the CPU/Card case fans. Indicator lights 1, 2, and 3 are on, blue power button. Miniview displays "System battery voltage is low" and "No display device found". After the messages and indicator lights came up I heard two quick beeps. I also plugged this directly into a wall outlet and got the same results. The hard drive, dvd burner are not connected yet. network card, phone/fax, video card are not connected.

I am headed to the store to pick up a new battery CR2032.

I have an XPS 420 and all of a sudden it is doing the same thing. Won't start, fan running on high, and panel lights 1, 3, & 4 lit.

Curious if you've solved the problem. I haven't changed anything on this sytem in over a month.

This was rediculously simple on my computer...I saw some postings about changing the CR2032 battery on the motherboard...as I was attempting to remove the old battery I heard it "click" into place.

I hit the power button and...voila...no more problem!

Hi Svangogh,

Just wondering if since your post the problem remained resolved as I'm also encountering the same problem on an XPS 420 bought in 2007 and cant find a single definitive solution? Also by changing that battery mind if I ask, did it affect anything else, HDD or just reset system clock? Any insight would be greatly appreciated happy

new motherboard and memory did nothing. when the tech saw the lights (the same the i told the indian phone support) he said it was the video card or psu...

dell told me either get all new parts and hope it works, or if the parts arnt available (its a 2 year old system) get a replacement from a newer model. however that would take up to 3 weeks!!! i said look for the parts, i wasnt waiting 3 weeks...

i suggested giving me a $500 coupon towards a new system, they said no deal...

today they replaced the cpu, psu and gpu and it works now. the tech said he thought it was only the gpu tho. oh well, new parts in my computer now

It does sound as though your CPU or Powersupply was faulty. Glad you are up and going.
