OK.. so the gist of this is that about 3 years ago a i bought a XPS730 system from dell because i loved the case and they were going for a price that was about $100 over the component value. From day one it has been in some state of broken. The specs are below.
CPU: Core 2 - Q9550
MB: 790i Ultra SLI (Dell manufactured i assume) (Replaced by dell)
RAM: original (DDR3 4 x 1gb) (Some cheapo brand) Replaced 2 x 2GB Gskill ripjaw-x 1600 mhz
GPU: original 2 x 9800GT's (Dell manufactured), replaced 2 x GTX275 gigabyte
HD: 2 x seagate 1 TBs and a seagate 2TB (Origninal 750GB WD died)
PSU: 1000W 80 plus certifed (unknown brand)
The problem is not very specifc and crops up randomly, always causing a hard lock-up requiring a reset. This only happens in games never when the system is idle or just running windowed applications... though once it occured when watching a HD video.
Things i have looked at/tried
-- Bad gpus: Replaced same problem
-- SLI: Happens regardless
-- Bad RAM: Replaceds same problem
-- Windows/Software problem: Tried running countless combinations of xp/vista/7 with all possible drivers installed/unistalled 99.99% sures its not software
-- Heat: Fan on 100% (Sounds like a jet taking off) monitering all temps... cpu does not exceed 50C and gpus dont exceed 60 to 65 (one is warmer) still locks up
--SMART HDD Monitoring -- disabled no change
--Voltages: tried various combinations based on advice and other users experience, no change... Though indicated voltages by CPU-Z and other monitoring are always lower by 0.05 volts... and the 12V line drops to 11.8V on occasion.. i dont know alot about that so i dont know how typical that is... but that all the time with no change recorded as it locks up
-- Memory timing and frequancy: Tried various combinations as per advice, no diffrence
-- Tried disabling network/sound on MB: no diffrence
-- MB was replaced by dell early on no change
-- Stress testing with P95 -- Runs for 48 hours no problem...
-- Mem Test: again 48 hours no problem
-- PCI-E connectors (power supply): used all possible combinations with one or two cards
At the moment the last thing that i can think of is the PSU (or its haunted) as generally low load games dont crash as often... ie minecraft or half-life... though certain games crash at certain points and the problem goes and comes randomly, might be able to pull a few hours then it locks up, reset and only last a minute... im planning a new build atm but i thought why not try and resurrect it one final time... ideas? (Ghost busters is a possibliity)
