Dell XPS 420 desktop won't bootup

May 22, 2010 at 00:44:40
Specs: Windows Vista Ult
Hi, my computer will not bootup. The only thing that happens when pushing the power button is the Fan goes to High speed and that's it. Monitor looks to start, then goes to standby. I cannot do anything, safe mode, Bios, using boot disk and windows vista ult. disk does nothing.. All this happened 05/18 after updating windows then Norton 2010. I then used system mechanic to clean, sometime during the cleanup the screen went black and the fan went to high speed, all fans (4) run, 3 in case including PSU and the graphics card. (I was out doing something else)
I had the PSU tested and it was OK, and even used a different PSU. I tried pulling my memorycards (4 1gig boards) and using just 1 gig at a time in top memory slot with no change. I plugged my backup HDD in as the main hd just to see if there was any change, but same thing. I was told most likely motherboard, I changed it but I still have the very same problem. I think I'm down to my CPU(Intel E 6850 3ghz) or Graphics card (Nvida 8800gt.) Not sure which to change or if my thinking is correct.
Any help in what to do next??

Thanks for any info

Ron

The Norton installation is *probably* a coincidence. But I don't know why you would wanna use that garbage software in the 1st place?

The fan on high speed seems to indicate the CPU is overheating.

Thank you for the reply.

None of the above, Windows Vista Ult., Norton 2010 and System Mechanic were new installs. All have been on my system for three years with no problems.

I thought of that causing the problem and maybe killing the cpu, But I thought by me changing the mother board would make the startup different on my first try?

Remember, the only thing that happens from inital startup is high speed fan, all else looks to be powered but I can do nothing else ie go to bios, safemode or use a boot disk.

Thanks again, and hoping for more info

On the Norton, I left it many many years ago vowing never to return, but it came preinstalled on my system, It seems to do what I need it to do fast and I have not had one problem unlike the past. hence it is still on my dead system and this old XP computer

Would typically take time for the CPU to overheat, it wouldnt just START overheated...unless its completely fried somehow.
Have you tried a new CMOS battery?

Hi and thanks for the reply.

I put in a new battery today, along with insuring that my memory chips 4x1gig sticks were good.

Any more info on my problem

Thanks

Ron
