This issue has been plauging my system ever since its purchase two or so years ago; the problem can be summarized as follows:
1) System boot begin.
2) Approximately 8 seconds later system shuts down.
3) System automatically reboots
4) System remains idle indefinately (fans are active, that's all I can perceive)
Note: The video display is never initialized; thus I receive no output.
I've also observed the following.
a) CR2PR LED illuminated red. (Does not appear to be occuring anymore)
b) A system beep pattern that sadly I can only describe as similar to a siren. (Occured only once)
c) The LED adjacent to the primary power supply is green.
b) After leaving the system off and returning it did resume normal operation for a very brief period (windows was booted) -- this no longer applies.
I have performed the following standard procedures in an attempt to resolve this issue:
i) Reinstalled memory modules in alternating slots.
ii) Reinstalled the processor fan.
iii) Removed all components leaving merely memory-motherboard-processor.
ix) General dust removal.
Unfortunately I have no spare compatible memory to do an exchange test.
What triggered this issue, as odd as it may sound, is that approximately two meters away from my system my XBOX slipped from the apartment under my TV which resulted in an immediate crash of my system and upon reboot the BIOS informed me of something regarding hardware changes and a short time later it entered the current state described earlier.
As mentioned this issue has so far occured three times. Originally it occured within a week of receiving the system (it's custom built, but was assembled by the shop for warranty purposes) and in this instance the problem magically disappeared with no known correlations (this did concern me as such behaviour is obviously not normal)
In the second instance I went through a 5 months procedure of having the shop test components; according to them, there were no issues so I deduced that it was the power-supply (the only component that was not sent). Given this, I purchased a significantly more powerful PSU with as many surge-protection features I could find -- this did not fix the issue, it turned out that one of the memory modules was indeed dead and thus I began utilizing only one.
Following are my systems specifications:
Motherboard: Intel DX58SO
Processor: Intel i7-920
PSU: Corsair TX-950 950W ATX
Memory: Corsair TW3X4G1600C9DHX 4GB (2x XMS3 2GB) PC-12800 (1600MHz) XMP DDR3 RAM
Any help would be greatly appreciated.
