( Post is kinda long, thank you very much ahead of time if you can respond with some help. ^_^ ) Hello everyone, I'm very new here and only just discovered driverheaven. Wonderful site, my compliments. Alas though, Ive been having some major issues since putting my pc together, here is a quick rundown of the specs. Processor: AMD Athlon 64 FX-60 Memory: 4gb Kingston Hyperx pc3200 (I know windows only goes up to 3 but it's in case I upgrade to 64 bit or vista.) Motherboard: Asus A8R32-MVP Deluxe Video1: ATI Radeon x1900 Crossfire Edition (512mb) Video2: ATI Radeon x1900xtx Crossfire Ready (512mb) 2x 250 gb Western Digital Cavier Sata2 drivers, (setup to be raid0 16x stripe) Fortron 700w PSU Sound: Sound Blaster X-FI Fatal1ty Primary issue: I am unable to install all of my x-fi drivers without somehow fubaring the rendering modes of crossfire. If I do not install my soundcard drivers and then enable crossfire and run dxdiag tests it will render fine. Perhaps some slight flicker as it's first loading the image. Then I try installing anything soundblaster related that is not just the core drivers and console, and it will bluescreen me out with the blame on ati2dvag.dll everytime. I've tried omega drivers (did not see a crossfire option, so I removed those), CCC, ATT , everything I could possibly think of to get rid of whatever conflict is happening. Each time i've made sure to do a fresh install by reformatting and re creating the raid0. Each time I update iether driver it's the ati2dvag.dll again. I am using the latest bios 0311 from asus for the a8r32 and it improved many of my beginning issues but this one is longstanding. Secondary issue: When I do have my pc running properly, it would appear that my monitor and video cards have some sort of refresh issue. When I am installing something or basically doing anything that makes the pc access data in any form, I see very slight refresh lines that are noticable on white backgrounds or very light backgrounds. This is on a NEC Multisync LCD 1960 nx 19" viewable i believe. I have installed monitor drivers. Another thing that caught my eye is when I bring up my monitors options by pressing menu on the monitor itself, it reports this to me \:::::/ 1 D - SUB FH: 48.3 kHz NEG. FV: 60.0 Hz NEG. The monitor is set to native and I haven't the slightest clue what the offset between FH and FV means. It varies everytime I change the refresh rate, sometimes higher than FV, sometimes lower. If you've taken the time to read my post and respond, I thank you honestly. I've been working on this for the past 2-3 weeks. It would be very nice to play q4 with crossfire and x-fi going. 3rd but not so important issue: I crash when alt tabbing out of many games in crossfire mode. Usually I can alt tab ok until I update CCC and x-fi drivers, then, if i'm even able to run at all. It blue screens with a different error. One that I cannot remember, something like ati2MTsomething sounds similar. I will look into it some more. Cheers guys, keep this awesome sight goin. I look forward to contributing what I can.
