Computer shuts down

1) the function can be the power supply box ffaulty, see if the fan are RUN, and test the power supply for +5VDC, otherwise is faulty the p.supply box
2) However you must RUN the software from DELL coming with the computer, or contact DELL for chat ONLINE,

God bless you

first thing to do is replace lamp .When a lamp has some hours on it .It will act just as you mentioned (cycles) .Also make sure fans are running and not clogged and or crusted with dust.If fans are full of dust ,fan spins slower ,causing a shutdown...

yeah, make sure the CPU is not getting heated, check for any loose connections, check the power supply is working, if this is a new computer and it has warranty, I advise to take it back and have it checked or replaced by a professional.

Faulty motherboard or power supply. Best guess is a fault in motherboard causing excess current and it then shuts down. Try unplugging all peripherals except for graphics card, including the drives. If still nothing, try a different graphics card, different power supply. If still nothing, try a different m/board.

the Fan has the problem , I had the same of yours. I noticed some particle was inserted in the center of the fan and removed it , worked perfectly. If old one produce little particles.
Good luck.

Power supply has several voltages. Just because the 5v power is active doesn't mean all the voltages are OK. You need to have the power supply tested for 12v and 3.3v. A quick test is to unplug all the wires from the power supply. There is a single green wire on the motherboard main plug. Connect (use a bent paper clip) that green switch wire and any black wire. Plug in the power supply and it should run (fan starts)

sounds like your power supplie has not been switched on by *********** board.the fan will not turn on until power supplie is turned on by mb.as far as what is wrong there are several things i can think of.i would try resetting bios. It sounds like your power supplie is working and your motherboard could have a short.but i have no way to be sure without testing. I can however tell you how to perform a test on your power supplie.unplug the 20 or 24 pin connector from your mb. look for a green wire,and then locate the grey one.short these two together(you can use a paper clip or something).if it dosnt power up. your power supplie is bad.also do not short any other wires,and only touch the grey and green for a few seconds as this is not how it was intended to be powered on.

bad power supply

I have had this same problem twice in the past 3 months. So far both times I've been able to get it back after a week or two. I'm not sure what works, but unplugging and detaching the antenna and cable and waiting a few days seems to be the key. In both instances, I unplugged it for a few days then plugged it in for a few days and repeated the processes until I eventually got the steady red led. Both times prior to the red led the led would flash red then green and make a clickiing noise for several hours before I was able to get it working again.
