Hello, I've followed the steps in the sticky about minidump to see if this was a ram problem but nothing came up to prove it (ram ment to be compatible with mobo, ran 16 hours on memtest, disk check came up clean etc.) I have recently installed some new components into my 2 year old computer -Gigabyte SLi nforce 4 mobo, Athlon 64 3200, 1GB ram and a 7800gt and a new PSU. I'd never done anything like this before but I managed to get everything connected right I think. It is only really when I try to run Battlefield 2 (out of the games I have) that this error happens for certain (loads all the way then crashes when the game is about to begin), I got the F.E.A.R demo to try it out and its only happened once out of playing afew times and I can play CoD2 for hours and I've never seen this stop screen then which seems strange to me. I used to get the screen even when browsing or trying to launch any game (even some as old as Morrowind) but now it only happens with BF2 really - I havent changed anything to my knowledge which is also strange. If anyone has any ideas please help - been battling this for 2 weeks - really tried to avoid posting by trolling help sites but nothing has helped. I think thats everything. Thanks in advance - Graeme. PS: This is my first post so here's a quick Hi to you all And Merry Christmas since we're nearly there.
