Dell Insiron 620 won't boot after CPU upgrade

Hi all,

I upgraded the CPU in my Dell Inspiron 620 from a Intel Pentium g630 to the Intel i5 3570k.

I used the heat sink from my old cpu because the heatsink that came with my new CPU wouldn't fit on my board. I researched it, and it seems that isn't the problem. The old heat sink is fine with the new cpu.

Now, when i power on the computer, all the fans run, the lights turn on, etc. However, the computer won't boot. Nothing is showing on the monitor.

When I put my old cpu back in, the computer boots just fine.

I have no idea whats going on... i checked dell's website to see if my BIOS was up to date and according to the website, it was. I wasn't surprised at that because the computer was new.

Also, i did research before buying the new cpu and people claimed that the new cpu would work with my current motherboard.

Can anyone help me?

So the motherboard will not support the cpu?

Since the 3570K is an Ivy Bridge CPU and the CPU's that it supports are Sandy Bridge, it'll definitely need a BIOS update (if one even exists), but regardless of that, there's no reason to get a 3570K anyway, since you won't be able to OC it with that mobo.

K. Thanks for the help. I'm going to return the processor and get the i5-2320.

However, the screws to my heatsink are stripped! I can't get it off!

Yeah, that could definitely be a problem. Not sure what to tell you there.

What do your screws or heatsink look like?

They're 4 phillips head screws... they have a spring mechanism on the ends of them. I have two off them off, however the other 2 are so stripped that they don't even look like phillips heads anymore. I literally have no idea how I'm gonna get this heat sink out.

If you have a dremel you could cut a slot for a flat head screw driver.

That, or I would try a pair of needle nose pliers on the screws, if you can get a good enough grip on them. Gonna be a pain to reinstall, though.

AND I see that jay_nar2012 just recommended that too, lol.

I'm trying to use needle nose pliers right now... no dice.

I'm gonna have to bring the computer to work tomorrow and use the dremel.

This sucks.

Remember to be careful and move any cables away from the heatsink...

A dremel is going to be difficult to do since the heatsink is already attached to the motherboard and the motherboard is already in the case... idk how I would do it without sparks flying and damaging everything =X

You could take the mobo out, put it on a piece of non conductive material, put another piece on top covering other parts except the heatsink and try it from there...
