Okay... here's the deal:
I built a system recently with the following specs:
GIGABYTE GA-MA78GM-US2H Motherboard
AMD Phenom 9600 Agena 2.3GHz CPU
Sapphire Radeon HD 4850 (with megasink/megafan)
Kingston 4GB (2 x 2GB) 240-Pin DDR2 SDRAM
Western Digital Caviar SE WD2500AAJS 250GB SATA HDD
Old MBD 450W PSU (pull from eMachines T2742)
XP Pro on primary part/ Vista on extended part
I purchased the video card from newegg for my previous, now defunct, system. Got everything put together and had no issues other than during 3D gaming. Fallout 3 wouldn't run for more than a couple of seconds before VPU recovery crashes. Left 4 Dead ran fairly stable but with green artifacts and low framerates. I RMA'd the card to Newegg, who replaced it with an open box of the same model. Fallout 3 now ran at max settings like a champ. L4D now runs very smoothly with high settings. HOWEVER, the character models have crazy beams of light coming off of them. Exact problem when running both XP and Vista. See pics:
I have taken the following steps so far:
1.) Checked card temperature in CCC. Running well under 80C most of the time. I took my comically large fan to 100% for good measure. No change.
2.) Pulled RAM and tested them one dimm at a time. No change.
3.) Uninstalled most recent catalyst driver. Used Driver Sweeper to wipe remnants. Rolled back to catalyst version 8.12 (driver only no cat suite) from 12-10-08. No Change.
4.) Installed clean version of Vista Home on extended part. Made sure DirectX was current version (10). No change.
I am now at the point where I question the PSU. It is 450W, and the video card has a dedicated power connection to itself (the HDD and CD rom share another cable), so I kind of doubt that it is really the problem. Before I go buy a new Antec or other name brand 500W psu, does anyone have any other (free) suggestions?
Thanks,
Kyle
