I recently purchased a custom built computer by Netplus according to these specifications:
Intel Core i7 920
Kingston 6Gb DDR3 (Value I presume)
Asus ATI 4870 1Gb
2x 1Tb Samsung SATA2 in RAID 0 (partitioned into 300Gb C drive and remainder into E drive)
Sony 20X SATA DVD Writer
Antec Sonata III with Antec Earthwatts 500W power supply
MS basic keyboard/ mouse pack
I've installed Windows 7 RC as the OS.
Whilst playing COD4 online at 1920x1080 resolution I found that my computer would always bail out from the game catastrophically and I'd be left with a black screen with the only option to push the reset button (CTRL-ALT-DEL DID NOT work). This would happen at random points in the game, not at any particular stage nor after an elapsed time.
Upon investigation into the event viewer, I was surprised to see that for every occurrence of this shutdown there was a corresponding Critical level event generated from Kernel-Power with event ID 41, stating that "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
So I went back to Netplus and they said that I needed extra power, stating that the 500W probably did not provide enough juice to the graphics card. So i ended up buying a Corsair TX850W power supply.
Thinking that the problem was solved I happily installed the power supply, verifying that all connections to the mobo, graphics card, fans, HDs and Optical drives were connected.
I fired up COD4 not expecting anything to go wrong, but indeed I got another complete shutdown, with the same event ID in the event viewer.
I'll be grateful for any help to find out why this may be happening and to suggest possible solutions to the problem.
I've googled but everyone seems to be pointing to an underpowered rig, but this is a brand new 850W Corsair unit.
Thanks in anticipation,
