new user I have an ibm netvista 6794,ibm mb, 1.8 intel pent4. it came with 256m ram and has 2 additional expasion slots for a total of 3 slots of ram. man specs says that it is upgradable to 1,5 g ram. i ordered 3 stics of pc133 512mb hd sdram. it will accept only 2 out of 3 at any one time . i have tried all combinations of the 3 and all slots they all work but just not all 3 together. at startup windows (xp pro) starts momentarily then a bsod flashes then it goes to the set up screen and again and again. I have tried all options from there with nothing. after this i shutdown remove the 3rd chip the get an error memory size. then from here i can get windows to start using the continue option but the only way to get proper startup is to remove the 512mb and reinstall the 256mb then shut down and install 2 512kb. I have alredy updated the bios from ibm to the latest (2004) how do i pause the startup so i can actually read the bsod and know what the actual error is ? and are there any fixes so i can fully upgrade my ram to 1.5g ?
