Replaced CPU ON A 775 Motherboard now it is not working
I just put the e8600 in my board the fan span but nothing else i put the tester on that just stayed on all the o.Have i put the CPU the right way?I can,t see any bent pins on the socket can you?i just don,t understand why it is not working now?Can any one tell me why just changing the CPU would stop it working?The dvd player works light on it opens no bleeps. I can,t send it back as it was working when i got it. Good job i did not buy the £9 CPU for it.It could be that the E8600 does not work as the board it came with i could not get it to work.I took out the CMOS battery that made no difference,

Not all 775 Cpu's are Supported by all 775 motherboards
Early Boards may not support late CPU's
1st thing to check is if your motherboard does support this CPU
you might just need a bios update

i get you there,but mine is.

ASUS P5KPL-AM Motherboard LGA775​

E8600 - AT80570PJ0936M / BX80570E8600 / BXC80570E8600
E8600, 3.33 GHz, 1333FSB, L2:6MB, 65W, rev.E0	0403	Any

I would not think it needs a bios update as the one on the board is E6400 ,i could understand if it was a Quad core 2 but not a core2duo.And how could i update a bios if i can not get a picture on the monitor?The lights on the keyboard light up for a few seconds.Why does the PCI Tester only show 0000 ?Is this the sort of thing that happens when changing a CPU if it were to do with the BIOS.?I have put the CPU it came with still not working.i did not put the heatsink fan on there.

Should be working if board is on 1.01G bios if MB is working. I would think you could even drop in a Xeon X3360 on that board since it supports Q9560 that works for me on a Biostar P43 board and it ran like a top.

Put the E6400 back in the mobo & see if it works. If it boots, get into the BIOS & see what version you are running. V301 seems to be the original, V403 add support for the E8600 and V603 is the latest available on the Asus Support site.

First, was CMOS reset after the new CPU was installed?
(I just recently had that issue pop up on my X570. Had to switch-back to my 3600, and forgot to reset CMOS 1st boot. -I about pooped myself )

Question:
The board isn't LGA771-modded, is it? (Are the 'locating nubs' still there inside the socket?)

If the board has been modded for 771 Xeons, it's much easier to accidentally install the CPU in the wrong orientation.

Being LGA, dust and crud can get in there and cause problems too. I'd pull the CPU, inspect the pads on it, and the 'pins' in the socket.
If there's 'collapsed pins', STOP. It's VERY EASY to break those pins while bending them back.

I have just tried that it doesn,t work . I wish he had put a better cpu in there

i wish i had updated the bios before i decided to change the cpu. I thought it would be a simple job..
No it is this tiny board,i have never heard a PC so quite
i have a feeling it might be to do with the crappy intel plastic pin cooler .that i am not getting this to work that is.
It should have posted with out the cooler on it.I have a PC dust blower to get any grime out of the socket if there is any in there.

You were right there was a bit of dust in there i blew it out.It was bleeping keyboard light was on but could not get into the bios.I tried it without the heatsink fan on.I tried first with the one it came with it was a e6500.Then i tried with the e8600 so far so good now for the cooler..

Cool. Running w/o a heatsink isn't a good idea, but I see your logic in trying it.
I'd be less worried doing that on an old Socket T chip (as you have), than anything 'new'. While there are 'thermal protections', on new stuff, you could get destructive hotspots before it can shut itself down.

Thanks for that ,it is amazing what a little bit of dust does.All working thank god.And i got my Canon camera to work on Windows i can,t get it to work on my Mac.Tell me about bent pins this was my first try for AMD good job it was only a CHEAP Athlon 64

I realize that but i wanted to check before i put a Heatsink on,it was less than a minute.I agree with you there I can,t be leave how quite this old core2duo is ,it only has what looks like the newer thinner intel stock ones.fans.

Clean and tidy for the Win!

Enjoy your 'new' 775

I put a 2TB SSD in mine today (just over $40 on ebay) as it still does sterling duty as my main machine.

Looks like you are limited to 4 GB RAM, just enough to run Windows 10

That,s a big SSD 2tb to put in such a machine, And still your main PC wow.Yes that is right,i am going to put a older system on there. It is slower than a snail on the HDD on my 775 I don,t know why anyone would think of running a HDD on Windows 10 and with only 2gb of ram.I Downloaded crystal disc info it says it is good.

(DARNIT! I don't have pics... guess it didn't happen)
If you think that's neat, imagine NVMe and Optane on PCIe 1.0 boards (like, my K8N-DL, with dual 885 Optys)

Don't get your hopes up, it's a royal PITA getting NVMe drives booting, on kit as old as mine or older. Though, at least 1 mad lad has booted off NVMe in a 32-bit PCI-only board; PCIe-PCI bridge card, and a passive adaptor.
That setup'll get any NVMe at least physically-interfaced to ancient boards; it's too slow/complicated to be anything more than a curiosity IMO.

It's hit and miss 'how easy' it'd be to get alternate UEFI-compatible bootloaders working on your E8600 build's vintage.

check you mainboard cpu support.
