Dell optiplex GX620 loud processor fan noise
I don't think you can install 8gb of ram into that desktop. If the processor fan is too loud check it for dust or any other obstructions. If there aren't any try replacing the fan - it could be a bearing in the fan.
Cooling fan speeds then cpu shuts down
That would indicate overheating ... do the usual checks = blocked vents, dust clogging the CPU heatsink etc ..
Then the less likley, such as a loose fan cable, loose CPU (or other) heatsink etc. (you might want to reseat the CPU heatsink ...)
Still no luuck ? Well, it's time to start unplugging things .. reduce your system to the minimium, maybe some plug-in card is upsetting things ..
If 'none of the above', then it's possible the power-supply is sending incorrect voltages or the motherboard has failed in some way (eg the temprature sensor under the CPU chip)...
PSU's are cheap, so replace that before replacing the motherboard

Three possible conditions of fan noise.
A condition of functional computer component parts
first, an overloaded memory due to several programs installed on the desktop bacground
second, a disk in the driver compartment generating fan energy to cool the system. Caused during movie displays using the computer disk drivers, or burning disks with the disk driver. Third, an extensive use of the computer requires more fan energer cooling capacity.
solving fan over tasking
1. free up the computer memory requirements by removing malfunctioning software programs
2. perform a computer defragmentation located by clicking START, PROGRAMS, ACCESSORIES, SYSTEM TOOLS, selecting the options disk defragment
a. defragmenting redistributes files into spaces producing an effeccient memory function requiring least fan capacity.
3. perform a computer malfunct programs cleanup by clicking START, PROGRAMS, ACCESSORIES, SYSTEM TOOLS, selecting the options of disk cleanup
a. the disk cleaning removes remnants of fragmented files making performanc effective requiring least fan generate energy
conditions of disfunction condition in a component part
1. a broken component of the computer system impeding the fans effective performance
a. a foreign object in the fan compartment causes loud noise
b. a broken fan due to over heating
c. a manufacturers condition of prior computers that performed on fan cooling rather than heat sunk dispensing and obsorption

Optiplex gx620 2 beeps on start up, displaying 123.
If windows 7 you need to burn a repair disc & run it. Go to Maintenance, creat repair disc (use one CD & mark it with Dell gx62 on top, repair disc run first on bottom)
Restart your computer and hold down escape, F1 or F2 to get into the settings in the CMOS. You must chang the boot order of your startup. In CMOS use arrows to right to Boot to change to CD ROM then HDD so your CD will go into repair before starting the HDD. Each CMOS is different but usually you can use the f5 or f6 to change the order and f10 to exit & save the setting. Restart your computer after you put the repair disc in & that should repair your start up. I’m happy to help further over the phone at https://www.6ya.com/expert/wynn_5ba0205233ebfc15
could be any number of things... Bad cable, intermittent connection, bad video card. . . not enough info here to diagnose the problem
