I have 384mb of Crucial pc2100 cas2.5 DDR. I wanted to set the timings more aggresively (Ive never messed with timings before). My ram timings were set to "Auto" in the bios, so i set them to "Manual" and changed them. Then when i restarted from the bios it goes to the screen where it says how much ram you have, drives, etc.. then on the next screen instead of showing the irq list, there is just a completely black screen with the flashing bar in the upper left corner, and it just stays there.

The weird thing is that even if i relax the timings to more relaxed then they were originally it still wont start up. It has to be set to "AUTO" in the bios or it wont start up. Anyone know why this might be??
