PC turns off when almost any game begins
Posted on 2006-11-02
Where do I begin.
This is a relatively new system, perhaps 6 months old. The problems started 2 months ago, where the machine would get up to the XP Pro startup and then never complete boot, it would hang forever. We swapped the MB, and the machine worked for two days and began the same symptoms. We swapped the MB again, the machine still exibits that symptom on occasion, but the biggest issue is that starting almost any game causes the PC to power off. Tested games include Unreal Tournament 2004, Warcraft III. Please note that when I say starting a game, I mean if we start up the PC and immediately go into a game it shuts off.
I have set it to not shutdown on a halt error to perhaps catch a blue screen, but to no avail - it still just powers off. There is no indication of any relative errors in the event viewer.
I have updated the BIOS, swapped out the PS, vidcard, memory, and CPU - I have reinstalled the vid, sound and MB drivers/chipset drivers. I have also moved the machine to a dedicated line to ensure the wall outlet is ok. As a final hurah - I reinstalled XP on top for grins.
This machine will run continuously for days without shutdown if left in idle - we ran it from last Thurs till we got home last night from vacation, and it was still on.
System is a 939 MB - ASUS A8N Sli-Deluxe w/Nvidia n-Force chipset
AMD 64 3200 - Thermaltake cooler
2 sticks of Ultra 512 3200
Coolermaster 600w PS
Seagate Sata II 150GB hdd
NEC 3540 DVD burner
Logitec optical mouse and KB, both USB
XP Pro SP2, fully updated
Kaspersky 6 AV, fully updated.
I am certain this is NOT heat related, as this box runs runs at 38c and the chip is at 31 at startup, raises to about 37 after 1 hour of idle time. Any and all suggestions are welcome.
