upgrading from previous gen core core i3 to previous gen quad core i5 but won't work

[rmarc5]

I have these configuration and all is in good working condition

intel DH55TC socket 1156

500w rated psu

3gb ram

core i3 2.9ghz

gtx 560ti

hdd 500gb sata II

windows 7 Ultimate 64bit

deep cool gamma archer cpu cooler

then I bought a new processor since it is my first upgrade for 4years. I checked the compatibility and these processor core i5 760 2.8ghz is on the list, intalled it. I've also installed with an aftermarket cooler too which can handle 95w tdp. First POST is good (beep once) I've checked bios and all is detected w/o a problem current cpu reading temp @ 55c. Now after post and the logo of windows shows up just for a millisecond then I've encountered this error. "Machine check error" and then the system would automatically restarts the loading of OS doesn't work at all. After a couple of trial and error I've disabled 2 cores and guess what the system successfully booted, but I can't live w/ that 2 cores running only I need the full capability of quads. TIA

Hi ramsalam,

I am sorry to hear you are having problems with the system but let me help you with that.

If you disabled a core in the processor and the system booted up, means that there may be a problem with the internal components of the processor.

I recommend you running the Intel® Processor Diagnostic Tool that will help you testing the processor and it will generate a report of the product.

Here is the download link:

Here are some other steps you can try:

1. Clear the CMOS by removing the battery for about 20-30 minutes.
2. Test if possible a different Power Supply.

In case you are still having problems with the processor and if the previous processor you had is working fine I recommend you contacting your local support for them to help you with a possible replacement.

I removed the cpu and check the physical appearance and I've found out that there are 2 cpu gold pins slightly scarred. does really affect it's condition at all?

and I did try to log on to windows but doesn't work now I received bsod while 2 cores disabled sometimes I bump to machine check error. My h55 mobo have the latest BIOS update 0048 version. Maybe my mobo is not compatible with quad processor?? coz the owners cpu said that this is working on his gene 3 mobo.

I can't use intel tool right now..

At this point since you have done several troubleshooting steps and the issue persists, I recommend you to contact your local support for them to diagnose the unit and replace it if necessary.
