Computer Problem

[sfang42369]

I just installed a fan, and i tried to turn on the computer, the splash screen shows, and it suddenly shuts off. is there like a trouble shooting thing i should do because i have no idea what i did wrong.

its an old computer, but i jsut bought the fan. and should i say the specs of the machine?

Unplug the fan and see if the computer still works.
Try the fan on just a hotwired old unwanted psu but take care to watch for smoke or funny noises.

Its a cpu fan, its an Arctic Cooler 7. Something is making a whistling noise, either my hard drive or my fan. I read in another thread that if i turned off the power from the back, and hit the power button on the cpu, it would come on for an instant, and it did.

i have no idea what to do, if i unplug the heatsink will the cpu still turn on?

it was working before i installed it, and theres a cable called CPU with like a copper piece on the end, could that be the culprit?

I just got past the splash screen and windows loaded, but after a minute it shut off again.

that whistling is like a high pitched screeching noise.

SOLUTION: I figured it out, i didnt seat the heat sink properly, so i took it out and reseated it, the whistling noise is gone and the machine runs fine now. (or so i hope)

That's not hard to do when swapping heat sinks. Many times the old heat sink sticks to the CPU ever so slightly and/or the pressure from removal lifts a pin or two. For future reference, make sure to re-seat the CPU any time you install a new HSF.

Glad you got it fixed. I was just about to tell you to reseat the HSF/CPU until I read your update.
