SOURCE: d530 CMT minttower power problem

Hi, from your description it appears your power supply is ok.

Remove your RAM chips, clean everything with a soft brush or a can of compressede air [from computer store] Reinstall the RAM making sure it is seated firmly.

If this does not solve the problem, Are you using 1 or 2 RAM sticks? if 2 then remove them again and swap them around.

stick one in dimm2 and stick 2 in dimm 1.

If you only have one stick then beg or borrow another stick and try it. If all fails you may have developed a mobo problem.

SOURCE: Dell Dimension 8400

I have this exact problem.

The Dell Dimension 8400 will seem to randomly go into fan-jet-turbo mode on power-up and fail to boot. The problem I'm referring to is not a heat problem which an over-speed fan might otherwise suggest but a hardware problem the details I'll get to in a bit

I've done all the normal and obvious stuff that has been reported before

remove/replace memory
remove/replace AGP video card
removed all extra power loading / drives / USB etc
BIOS tweaks/resets
check supply voltages with a DMM (I even re-adjusted the hipot to get the right voltage - it was a little low)

As an engineer it is important to determine root cause. Do to this it is necessary to find a way to make the problem occur and not occur. If you're able to do this you can fix it.

Well in my case the problem it related to a mechanical stress on the heatsink. What I mean is a little force pushing the heat sink toward the fan turns off the problem (boots normally) while a little force in the directly away from the fan turns-on the problem (fan-jet-turbo-mode).

The root cause is could one of several things, it could be a damaged motherboard with a broken trace, it could be a socketing issue,

The Fix (not really - just a band-aide) was to use a tie a couple of small tie-wraps through a some small holes in the heatsink then through the fan mounting holes.

Only slight pressure is necessary - too much will likely cause permanent damage. The fan is mounted on rubber isolators so it somewhat limits the force on the heatsink

Any this mechanical issue is somewhat supported but all the information I've read - how removing/replacing the CPU can fix the problem, changing memory, removing cards - all these mechanicall stress the motherboard and likely move the heatsink some.

Intermittent problems are the worst to debug!

SOURCE: computer will not boot

http://support.dell.com/support/topics/global.aspx/support/dsn/en/tree?journalid=6EB139500365CBA6E040AE0AB5E109D6&treeid=286725

See that link for the beginning of the Dell troubleshooting wizard for diag lights 3 & 4, it is in fact a memory subsystem error. Usually meaning the stick of memory in the first slot is bad. The wizard will walk you through this, but try removing the first stick and using the second stick in the first bay and see if it will boot. Unfortunately no recalls on RAM for this model but the good news is that your memory is cheap and if your not under your service contract you can buy a set on newegg or a similar site for about 50 bucks.

Just to make sure thatnothing else is causing the problem, remove any PCI cards like modem, videocard, sound card, etc... Remove the memory modules and disconnect cables toCD/DVD drives. Look at the USB ports to see if any are damaged.

Dell inspiron 1501 wont trun on


There are a couple of things you should try:

Try booting with the battery out, check the power supply does it have a solid green led?

Remove both memory chips and try booting with just a single chip.

Any noises, led blinking, etc?

The more info you give me the quicker I can help.

My Dell 8200 Desktop just stopped working. It turns on but doesn't boot; nothing appears on the screen. I was told this is the motherboard. Does that sound right?


two things
  1. What does the power LED on the tower indicate? Solid Amber? Flashing Amber? Solid Green?
  2. On the back of the Tower are 4 diagnostic LEDs, what do they indicate? Normally they flash thru several sequences and stop ABCD all Green. If the stop in another pattern, post the pattern.

Screen will not come on hard drive light no light checked power supply is ok


Things to check:
  1. Power led on the front of the tower, it should be solid green when on. Flashing Amber is generally an indication of a bad power supply inside the tower
  2. Power LED Solid AMBER indicates system is not finishing the power on self test (POST) and you remove all connections from the tower except power and try turning on again. If no change, remove all PCI and PCI-E cards from system, try again, no change replace motherboard.
  3. On the back of the tower are 4 diagnostic LEDs near the ps2 ports marked ABCD, after the POST, during a normal boot the will flash in several sequences and with boot is finished all 4 should be green. If they stop an a different pattern, then that indicates a failure Yellow Yellow Green Green indicate bad RAM for example
  4. If the LEDs on front and back are Green then the system appears to be booting but the monitor display is not functional
