Bought this desktop computer a week ago, and it arrived yesterday. Specs: Antect 1200 Gaming Case Corsair 750W PSU (140mm fan, ATX/EPS, 8xSATA, SLi) Asus P5N-D nForce-750i SLi Socket 775 (ATX, Firewire, GbLAN, DDR2, 2xPCI-Ex(2.0)16) Intel Core 2 Quad Q9550 2.83GHz 1333MHz 12MB BOXED w/fan Corsair TWIN2X 6400C5DHX DDR2, 4096MB 2x Samsung SpinPoint 500GB SATA2 XFX GeForce GTX280 602M 1GB DDR3 512bit Creative SB X-Fi XtremeGamer soundcard MS Vista Home Premium 32-bit Pre-intalled by Komplett.no So here's the story.. on first launch, I was just filling in some forms about user etc, you know the drill. Then all of a sudden, when launching the "desktop interface" the screen went black.. "No Signal" I thought it might be normal, as these LCDs go black all the time when adjusting screensize etc. but it didn't go back on as usual.. so I figured something was wrong and rebooted. Filled in the forms again with a new username (cause it kept saying the other already existed, naturally 'cause I created it in the first startup).. this time it works fine, load the desktop and I proceed to read through some of the things in the welcoming screen. Then I delete the second user I made and everything worked just fine for a while. I made sure all the drivers from the various discs (asus, xfx) were installed, some apparantly weren't. Then I rebooted and started installing UT3, I was looking forward to run this on at least medium settings, 'cause I had been playing it on low graphics with my brothers 2-yr old rig with XP. Installation went fine, I launched and went to Settings. Thought I'd try it at full res 1900x1200 (or something like that) 'cause it looked really stretched on my BenQ 24" Widescreen. Screen went black again, for 5 mins before I rebooted. I had sort of suspected it would complain when I put it at full, I'm not used to playing on State of the Art machines so I always have to go for medium. So I went in the .ini and changed it back to default setting. Started the game and tried setting it to the lowest widescreen res, to reduce the stretch, same result. Rebooted and made nVidia refit the screen so it wouldn't stretch, nice black line son the sides. No changes in settings on UT3 and launched a new campaign. The opening movie runs fine, no lags or anything, as smooth as on the old XP-rig. Then when the actual playing is about to start, I get another 'No Signal' and I give it up. Uninstall UT3, look up on xfxforce.com for the latest drivers for my card, and for Vista 32-bit of course. Find they are newer than mine and install them. Then I download DX10 'cause I wasn't sure whether it was installed or not, and DX10 is the only reason I installed Vista anyway. Then I reinstall UT3 and try to launch, but now it crashes already at the login. I check the UT3 boards for tips, and find a good amount of tweaks to improve performance and fix well-known bugs. Did the things, no improvement. Figure my computer actually can't run UT3, for no apparent reason, and decide to install a different game. WarCraft 3, this game runs on my 6 yr old Fujitsu Siemens, with a nVidia 5-series card. It can't possibly have trouble running in high res, full settings.. or so I thought. Guess what I get? I get another crash- after adjusting settings once again. I actually haven't tried running a game on WC3 yet, but I've downloaded the latest patch and I can log on battle.net and join the chat without trouble. I did a little look around and found some performance check tools in the Control panel. And a tool to determine my WEI (or whatever it is, that rating that goes from 1.0-5.9) and tried to run it. It says the screen might blink a few times during testing, then it says "Testing Aero.." and black screen. Allright, it said it would blink so I'll let it run for an hour or so. Came back after a while to see if there was any change, while i sat there the computer suddenly rebooted and claimed to have had a faulty shut-down, and asked if i wanted to start in secure mode. I've run that test several times, with different drivers and without Aero- no visual effects at all, so it looks like Win98- but it gives almost the same result every time. With Win98 looks, the screen didn't go black, but it went blue-green. Ran another test I found, the one with something that looks like speed-o-meter, with a red field on it, says it'll run for 60 seconds testing. Result showed that my Processor, Graphics, Memory and Storage were poor. And that I most likely would need to upgrade. Something has to be wrong here. Any ideas? If nothing helps I'll try run XP instead, as I've heard it's still a lot better than Vista. Even though someone convinced me that my specs would make Vista 64-bit the best performance option. Wouldn't 32-bit run smooth if 64-bit is supposed to?
