Specs: Windows XP Home Edition, Intel Pentium 4 @ 3.20GHz, 4 Gigabytes RAM
I have an Intel Pentium 4 @ 3.00 GHz that has probably 5-10 pins bent on the bottom after I took it out. It is installed in a Dell Optiplex GX270, and when you turn it on, you get a solid orange light on the power button and the Hard Drive activity light continuously on. I have never straightened out pins before, so can someone give me some pointers please! ;(

✔ Best Answer
Straightening pins is a tricky business: toss of the dice. They can pop out as you are working.
1) ground all tools and the cpu - NO STATIC!!! one of those anti-static pads is handy.
2) I use needle nose plyers to press the pin straight. Don't try to bend. You have to use the pin against itself to do most of the correction. Simply closing the plyers on the pin should provide all the pressure you need. Practice on straightening a brass paper clip by closing the plyers only. No bending. Once you can do that, try a pin on an old cpu. Don't hold the CPU while you are applying pressure on the pins. Allow the CPU to move freely!
you're not going to get them perfect. Have to carefully work the CPU into the socket afterward. Then close the lever and never remove it.
Be aware the socket may not close properly for electrical contact. Then again, it may.

3) Wait for other posts to get more information / experiece.

Sadly, a pin broke off when I was straightening them. So it was an important one. Computer will still not boot when all other pins are straightened out.Thanks for the help anyways. I just need to get another CPU.

I'm guessing you ripped the CPU out of the socket by improperly removing the heatsink?

It's too late now, but pliers should not have been used on the pins. I've straightened dozens of pins simply by using a small screwdriver. And I've seen others recommend using a mechanical pencil. Just remove the lead, push the end of the pencil over the pin, then carefully straighten.

Yes, the heat sink was glued on to the processor, so I didn't pry heatsink apart, just ripped it out, and then pryed the processor off from the heatsink. :(

I doubt it was glued on. Did you gently twist the heatsink from side to side until the thermal bond between the heatsink & CPU broke? Or did you just grab the heatsink & yank? Regardless, the damage is done. You learned a valuable (& expensive) lesson.

I used a chisel and stuck it in between the heat sink and the top of the CPU and pryed them apart. But it did have something like thermal paste holding them together. I just looked on Ebay and I could get another of the same kind for $20. At least I don't have to buy an entirely new computer :).

Just make sure it is the same or at least supported. The P4's came for 2 different sockets and there was enough other major changes that all are not supported on all boards.

You have to be a little bit crazy to keep you from going insane.

Yeah, but fixing up the Optiplex isn't a major concern for me at this moment. I still know I should probably fix it at the risk of my main computer dying. Thanks everyone for the tips and advice!
