Hi, I got a new 256 mb Samsung Ram PCI 133 Stick. I open my case, put in the ram, and power up the comp. 3 little beeps.... I restart, 3 little beeps. I close the comp, then I replace the ram stick ok. Then I get in, it says Start Windows Normally and options like that. I press enter on Start Windows Normally and It starts well, but at Windows XP Professional Page Loading (the little 3 bars moving left to right) it loads a little but a blue screen appears for 1 sec and less and the computer restart. I tried to use Safe Mode... didnt work, restarted BEFORE loading, same happened for the last good working ;) I remove the ram stick, try again, and all the same errors again, anyone could help me?
