So many replies:Ok, first off, Atomic0...our local computer guy is the guy that put the celeron in wrong in the first place...and I live in the boonies. So, that's probably not the wisest choice, lol.Levimage: The old processor is kaput. It won't load into BIOS...that's why I'm having the problem. It just won't work.Darasen: The celeron we had was at least 800Mhz...I only know that because that's the minimum for what we use to play our games. The Celeron that was on it wasn't the original, I don't think. We need the 800 to play the games is the only reason we didn't go lower, or we'd just use the computer I'm on now (my ooooold computer...to upgrade this one...it'd be cheaper to buy a new one lol, and we just don't have that kinda money).vujsa: The reason the pins were bent is because the processor was connected to the fan...therefore using the lever was not an option. They weren't bent coming out, they were bent trying to be put back in because the lever wasn't able to be used. As for upgrades when this last one was installed, I don't know...it's my fiance's computer I'm trying to fix, and we weren't dating then. But I do remember him saying that he has had it upgraded to some extent, I just don't know how much. And he just left it there for the guy to work on it, I believe, and probably never asked questions, he was just glad it was fixed (that's just how he is...plus this was a while back and he's lucky to remember what he had for dinner 2 hours ago)As for removing it, I was cleaning the fan...it was so clogged I doubted it was doing much good, and the processor was attached to the fan. I've taken mine (the one I'm using) apart and put it back together like 100 times, so I do know how the insides go in, it's just that I don't think the processor is supposed to literally be attached to the fan...lol.I think I answered everything...if not lemme know.Thanks.

Okay, so, here's the deal. The guy who originally installed my old CPU installed it in a manner that the fan on top of it melted off any product numbers and all that. All I know is that the place it hooks into says mPGA478B. It was originally a Celeron. Well, when taking it out, the pins were bent, so I needed to buy a new one. I went online to find one, searched the mPGA478B thing, cross referenced it with the Dell, it said everything was a-okay. BUT, once I received it, it didn't work. The new one is an Intel Pentium 4, Northwood Core 478 Socket with specs 2.6GHz, 512 KB 800MHz. I've read that you CAN interchange a Celeron with a Pentium...but looking closely I also realized that the inside of it (those little rows of rectangles...I'm not a computer person so I'm not sure what they are called) are vertical, rather than horizontal like the old one. Now, does the direction of these affect whether or not it works? When I turn it on, the power light comes on, the fans work, but it just beeps. I've looked up the Phoenix BIOS codes, and the closest it comes to is the faulty CPU sound, so obviously that doesn't help out much to me. So, first off, I'm wondering if this part is even compatible, and if so, is there actually something (other than actually putting it in the computer) that I'm needing to do because I'm changing from a Celeron to a Pentium? Please keep in mind with that, though, that I can't run the computer it's on, so I can't log onto that one to download any upgrades or whatnot. Here is the information on the CPU and computer, the best I can figure. Let me know if more info is needed. Computer: Dell Serial Number: F7V8X11 There are two numbers written on the back: 76850264 and 7360D46 Model Number: MTC2 MoBo Rev: A00 Pentium CPU: Intel Pentium 4 2.6GHz/512/800 SL6WH 7329A635 6334A645 0729 That's all I can find, unless you need the really long numbers on any of the serial code bars anywhere. If so let me know. Thanks
