I have one that did that. I removed the heat sink. Then cleaned off the old transfer cream from the processor and heat sink. I got some new heat transfer gel in a tube from radio shack and applied it generously to the processor. When I reinstalled it it got quiet. The heat is not transferring to the heat sink so the processor is over heating.

Hyjackers,
Mohamed Hamdi wants more answers to this question

why not post your own post
with PC model, OS name.
and your actions and symptoms.

the OP failed to update hardware 1 part at a time.
if he had he'd know what part failed.
im guessing bad RAM.

he told the story backwards too.
if the HDD is new, there is no OS there. so... backwards.

my guess, he gut shot installed all new hardware
then got Windows 7 disk from the tooth fairy?
HP disk set, MS diskset or from hackers./ whos disks?
then installed it and failed.

ignore the fan, untill the OS works.
BIOS runs the fan hard , to keep it cool. (and regulates it)

the fix is easy
go back to no upgrades, just a new HDD. 1TB drive.
install W7, ok works ,see?
now add things 1 at a time, see where it fails now.
that is the best way.
one at a time, and activate last, when all is good.
win.
end hyjacked post answers

8 G of RAM seems a great deal of RAM. Are you sure it is the right type of RAM.

Windows 7 will run perfectly on 3 GB.

Some fans can be noisey, have you cleaned the heat sink recently? Vacume the grill on the heat sink. Also somtimes when the weathe ris hot cooling fans will speed up!

If all else fails you can get fans that are quieter and you may wish to upgrade, I would recommend a fractal cooling fan.

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.

Processor fan sounds like a vaccum. upgraded to 4gb of ram and a new hd video card as well as a 1tb hd. I bought 4 more gbs of ram but windows wouldn't start when i installed it.

The problem could be that the fan you have is not sufficient to cool your sysyem, after a big upgrade like yours.
You should try to buy a new oer two new fan and install them on your pc.
Let us know if you solved

Dell OptiPlex GX620 starts up then shuts down repeatedly

Try this: remove the DMOS battery and unplug the on/off switch plug. It's the one in the corner near the power supply. To be sure follow the cable from the front on/off switch board on back to this plug. Then plug the A/C cord in, if the system boots up fine, then replace the front panel power on/off swith board. Naturally you will not be able to power off the computer using the power switch (since we unplugged it), so you will have to just pull the plug. Hope this helps. Joe
