256mb might not be enough for games.
I have a Dell C600 Latitude Laptop. I use it just to play games on and stuff. Doesnt have a lot of mem on it, 256mb. Windows XP. I had a problem come up and I reinstalled my windows xp on and now i have this mem error coming up as reads: memory write/read failure @ 04000040, read 80EF00EF expecting 00EF00EF. Decreasing available memory. The amount of system memory has changed. Strike F1 key to continue, F2 to run setup utility.
I have tried both, F2 well, I dont know what they want me to do there. It still shows 256mb as the available memory and the F1 well just lets it go thru. Do you know why I am suddenly getting this message and how do I or what do I do to get rid of it.
Thanks for your help.
