Which CPU

I went to clean out my PC with one of those canned dust removers. I obviously didnt know what I was doing because the heatsink and fan was nasty. So I removed the heatsink and fan from the CPU. Big mistake. I did notice some kind of metal that looked like it connected the cpu to the heatsink but didnt think removing anything would mess it up. Needless to say after turning on the PC and running for a few minutes the PC totally shut down. I am guessing I need to replace the CPU.

The PC is old and out of date. I did get a new laptop that I am pleased. I was thinking about just sticking a new CPU in there and letting the kids take over for whatever.

My problem is deciding which CPU to install.

Micro Star MS-7211
PM8M3-4

Wouldnt spend much around $50 would hopefully do it.
 
it probably overheated and shutdown. you probably didnt to any damage. buy some arctic silver 5, it is a thermal paste(which is what you removed) and reaplpy it betwwen the cpu and heatsink.
 
Yeah - when you said some kindof metal was removed - are you referring to a bracket or locking mechanism on the motherboard - OR - are you talking about something sandwiched between the Motherboard and your CPU.

If it's the latter then it's thermal paste.

It's a gellike fluid that allows the heat to uniformly flow from your CPU - to your Heatsink. You need to clean both contact surfaces with Rubbing Alcohol ( 90% or greater ) and lint free cloth. Then get some Arctic Silver 5 or similar type of thermal paste to re-set your heatsink onto your CPU.

You should be good to go after that.
 
It's just your thermal paste, and it just shut down from heat. I also doubt is actually destroyed the CPU.

You don't have to get AS5 paste. Just go to your local Staples or other PC place and get any thermal paste they have. At staples they have some good stuff I use called Antec silver, it's $10 and give you atleast 5-6 uses from the one tube.

So first you want to clean the heatsink and the CPU up real nice. Use so rubbing alcohol and a couple cutips. Leave the CPU in the socket, there is not need to remove it...you only risk bending a couple pins if you remove it.
After the rubbing alcohol dries, apply the thermal paste. Just squeeze out a dot in the middle of the CPU the size of a small pea. They clamp the heatsink back on and you're done.
 
In other words: removing thermal paste = instant overheating. Just do what everyone else is saying and it'll be fine.
 
don't use a pea-sized amount of thermal paste. that's massive overkill. what you want to use is a rice grain sized amount.

I said small pea, and a rice grain is not enough when using arctic silver or stuff like that. Perhaps for silicon based thermal pastes it may be enough, but not for silver as it doesn't spread as easy.

This sounds about right. I still haven't re-applied the paste. Bestbuy didn't have any and I didn't know I could grab some from staples.

Instant overheating is what I am hoping the computer is doing. When I hit the power on button the power does come on but no BIOS screen. The monitor doesn't even recognize the PC being on. The green and yellow LED lights in front do come on and the heat sink fan fires up. No BIOS screen is why I believed the CPU was blown.

Well it's possible from what you describe because typically it would atleast POST, even without thermal paste I'd say it would take maybe 2-3 minutes to overheat to the point of shutdown.

Yeah, that's true. It definitely would do at least SOMETHING. Sad but true, you may have just blown it up. :(
 
I'm having a hard time locating your exact motherboard specs. But does this sound right.

CPU: Supports Intel Pentium 4 / Prescott (LGA 775) processor. FSB@800/533MHz. Supports Intel P4 Prescott CPU up to 3.8GHz above, and intel P4 Prescott Celeron CPU.
