This is caused by the Chassis intrusion switch. It is a "normally closed" spring switch. If the switch is removed the system will operate, but the Fans will be on full throttle and a message during boot-up will say "Thermal Solution Compromised". This is because the airflow can't pass properly through the system with the panel open. With the case front to the left, the pins are from left to right 1, 2 & 3. Placing a jumper on pins 2 & 3 will prevent the "Thermal Solution Compromised" message from appearing.
You will need to go to customer care it will be great if your device still has warranty.
none are this old, age matters.
this PC is 13 years old, no warranty !
the correct answer is ask any PC repair shop on earth to fix it.

I hope there an option in the BIOS that could disable chassis intrution detection. Please check the BIOS settings....
SOURCE: Dell Dimension 4700 won't boot properly.
Disconnect the hard drive and the floppy drive cable at the mother board. The retry POST and try to clear up any problems in POST. If this works fine then the floppy drive cable is either reversed at the unit or the hard drive is jumpered wrong.

Hey,
Go into bios or cmos setup. when you turn the computer on it says what you need to press to get in there, look over the bios, look for chassis intrusion detection, turn it off, then go back to the main screen save and exit.
you won't have the problem anymore.
Thanks and good luck.

It's all on a small board and control panel, both of which connect via ribbon cables. Have you removed the power switch, etc from theseboards?

NOTE: When the administrator password is enabled, you must know the administrator password before you can reset the Chassis Intrusion setting.
This feature, if installed and enabled, detects that the chassis was opened and alerts the user. To change the Chassis Intrusion setting:Alert! Cover was previously removed.
To reset the Detected setting, enter system setup. In the Chassis Intrusion option, press the left- or right-arrow key to select Reset, and then choose On, On-Silent, or Off.

dell.com has 1000s of post there, same question read that yet?
turn it off in BIOS. security + intrusion F2 page
so if the thermal sensor tells you "overheating"
you defeat the sensor or fix the true cause.?
is this magic or hard to understand.
if your cars engine overheats do you remove the ECT thermal sensor then burn up $3000 engine,
do you?
The cause of CPU overheating if that.
is to look to see if the heat sink did not fall loose (or gremlins)did that, or HS is packed up in lint, or that the fan is slow and packed in lint, or the heat sink grease(called TIM) is now old hard and cracked and now useless.(renew it)
or you live in a CABANA and is 105F inside and noe PC runs this hot in a CABANA. (or the like)
95F max is spec. ok? for ROOM Temperature.
13year old T5400, with relic BIOS pages!
Xeon Dual-core 5200 or Quad-Core 5400 series 64-bit??
dont you love dells geek level errors.?
not.
it means this.
I am overheating !
or means the heat sensor is bad.
the tests are easy ask and free software to test that
google HWinfo32.exe ,free and safe.
run that see if it really is too hot.
the door switch is even more simple
the "intrusion switch"
if the door is open on some dells it also thinks this will overheat the PC, sure at 95F room temp.'s sure.
but can be turned off in BIOS
power on hit F2, bingo BIOS,,pages.
turn off intrusion there. cost zero and no hardware hacking by you.
of you ask at dell.com did you.
they tell you the fans do screem if door switch wrong. it is a feature, this PC can be configured with CPU that are power hogs, old CPU did that. run hot (certain ones) and has firmware protection. to avoid that.
called self preservation, dell servers do this 10x more strict than Toy grade PCs. for sure.
try this,
power on hammer F2.
bingo bios.
move to left side see SECURITY.
then in that box see INtrusion.
set it to OFF (disabled.
per here (amazing best bios doc's are here never at dell, dell does not document bios.
(maybe 100th of it)
https://youtu.be/xm4o7n6y-gY?t=80
in all cases of Fast fans assume PC is too hot
and next prove it is not then play with intrusion last.
The youtube is the best place to see bios
or on the actual PC if you looked youd see it.
here is the list of things any 13year old PC needs. super common cures, all.
surely not the silly switch first.
1:RTC coin cell bettery is bad, sure it is.
if that old IT IS.
if is bad BIOS goes NUTs, and even lies to you.
NVRAM scrambling is not good, do not let it do that replace the battery on all PC 5year old or older.(or use Voltmeter above 2.9vdc good below bad. (the Vm will no lie to you, use one)a $10 tool.
2: clean the PC, get the PC 100% clean, all vents /fans/heatsink fins cleaned, I use SHOP air, or walmart, CAN-O-AIR. blow it out.
I do this outdoors if super filthy as most are.
3: this old a PC is bad TIM the CPU grease (tech slang ) is now Jerassic level fossilized. hard old and cracked, replace it.
TIM is intels name for thermal paste, CPU to HS. or HS grease (slang) I use intel spec grease, called SHin Etsu. non is better.
4: HDD bad fails smart tests. (crystaldiskinfo.exe) free and safe.
5: once running said PC make sure it does not overheat, 90C is way too hot. 50c ok.
use HWinfo32.exe and look.
6: then kill the intrusion switch in BIOS, a 15 second job.
at the least that, , lots more but , I STOP.
NVRAM is the RAM that is called CMOS
the Coin cell keeps NVRAM from going to random data. Scrambled, (35years now same story)
the BIOS goes dead or acts super odd if this happens, and is a FIRST ORDER FAILURE never to be ignored. Dead or marginal battery.
COIN CELL:
The silly battery is always first thing to check. or nothing but bad awaits you, even thin wallet replacing very expensive good things not bad at all.
also the time of day or date can be wrong.
RTC coin cell means real time clock. chip
also
even this old, PC BIOS page F2 still has
at the bottom left maintenance + event log.
this is the BIOS event log
we look there first of any hint of wrong date
or NVRAM /cmos ram errors. or check sum errors of ANY KIND, and replace the coin cell,
spend a buck, be happy.
With the COIN removed, and no AC power
and then new replaced we then go in to F2 screen bios and reset BIOS
then set the HDD to 1st in boot order or the OS may not boot. (or fail to install and run)
see load defaults at dell.com
https://www.dell.com/support/article/en-...
the set boot order next (boot sequence)
to hDD first. in list. or SDD if wise upgrade.
