i wondered if any one could help me with a issue i am having.
this is the first time i have had to start a tread as i am completely stuck. i normally am able to find the solution using the forums.
basically i built a new system for a friend of mine, but unfortunately after completing the build i keep getting a blue screen at random points while using the system.
the error being "STOP 0x00000124 - halmacpi.dll+ef3f, ntkrnlpa.exe+cef04"
now i know this error is normally hardware related. so the past 3 days i have been doing alot of troubleshooting. but nothing i have done has worked.
Intel Core I3 540 (stock speed, not overclocked)
Asus P7H55-M LX
Geil 2GB DDR3 1333MHz
Asus HD 5450
Antec Earthwatts 430W PSU
Seagate 250GB 7200RPM Hard Drive
OS: Windows 7 Ultimate x64
the troubleshooting i have done so far:
flashed BIOs to the latest version
tried two types of other ram (with 2 sticks installed and then only 1)
removed graphics card (used on board graphics)
tried different Hard Drive
tried different PSU
removed it from its case and set up on a test bench. (make sure it wasn't shorting on the case)
replaced S-ATA cables.
i ran prime95 for 2 hours which reported no errors.
CPU temps are ok.
65-70C 100% load
was unable to run memtest86+, it just fails instantly (with all types of ram i tried)
then began to think it was a driver issue.
so i updated all drivers to latest versions.
also did a fresh install of windows after first errors.
the blue screens only seems to happen when installing programs or running 4-5 programs at one time. the system ran at idle for 24 hours, no blue screens occurred.
the only troubleshooting i am unable to do is replace the motherboard and CPU as i do not have a spare 1156 CPU/Motherboard to hand.
the only conclusion i can come to is the motherboard is faulty (or maybe CPU but more likely motherboard)
basically wondered if anyone else has a view or whether i should just RMA the motherboard/CPU (or both)? want to be sure before sending back the components as it will take a week or two to get them back.
have attached dump files below
