Here are my system specs for the record: Dell Inspiron 530 q6600 @ 2.4ghz overclocked to 3ghz 4gb of 800mhz ram 600 psu with 2 pci 6 pin connectors Liquid cooling 2 HD's. 250gb & 1.5 tb @ 7200pm 42 inch plasma tv GIGABYTE Radeon HD 4890 graphic card. 256bit memory interface, 1gb ddr5, 850MHz core clock, 800 Stream Processing Units, 975MHz (3.9Gbps) memory clock Now that is out the way. Here is my problem. I've been dying to test this gfx card out. I downloaded a demo of Crysis. on the 1st run, everything was fine. I think my res was on 1024x768. I then tried to bump it up slightly. When I did, the movement of my mouse was off quite a bit. I had to actually scroll lower than whatever tab i wanted to click on. Eventually my pc froze. So I rebooted and tried to load crysis again. this time, my memory skyrocketed from 700mb to 3.3gb. BTW, page file was off. Crysis said it couldnt run because low memory. Then I turned on paging file and set it at min 4gb, max 8gb. It still says same thing, low memory. I have no idea what the problem can be. I have uninstalled the entire ATI suite with your uninstaller, deleted registry strings, uninstall the graphics card drivers, reinstalled everything to no avail. Also, when I try to run it, not only do my mem sky rockets to the the roof, but the game itself does not cover my whole screen, only 3/4 of it, as if its resolution is different. Plus I get this msg also: Problem Event Name:APPCRASH Application Name:Crysis.exe Application Version:188.8.131.52 Application Timestamp:4718fd8a Fault Module Name:MSVCR80.dll Fault Module Version:8.0.50727.4927 Fault Module Timestamp:4a2752ff Exception Code:c0000005 Exception Offset:0001568f OS Version:6.1.7600.2.0.0.256.1 Locale ID:1033 Additional Information 1:a580 Additional Information 2:a580fb66e5132619b142ac800d3ffa2b Additional Information 3:0526 Additional Information 4:0526375c693ba30a6decf7da1e7c9ca0 Any and all help will be greatly appreciated.
