ram-boot problem

Hey i had a booting problem the computer just didnt want to start i solwed the issue by taking one of the memory sticks so im now left with 1 1gb stick and everything works great but as soon as i try to either start with the other one or wuth both of them computer doesnt start i would like to get back to 2gb instead of 1 can someone help?????????????:cry:confused

 

Could we have some system specs?

 

processor Type AMD Athlon 64 X2 Dual Core 5200+ / 2.6 GHz
RAM
Installed Size 2 GB / 4 GB (max) Technology DDR II SDRAM Upgrade rule (RAM) Max 2 x 2 GB module
Mainboard
Chipset type NVidia nForce 430 Data bus speed 2000 MHz
Graphics Controller
Graphics Processor / Vendor NVidia GeForce 6150SE Installed Size 128 MB / 399 MB (max)

theese are the initial specs

 

Did it work right previously? Are you sure you have the RAM plugged in the right slots? I think if you have two sticks it should be in the 1 and 3 slots. I'm not sure if it makes a difference.

 

doesnt matter where its plugged as soon as the second stick is in the computer doesnt boot

 

any other ideas? :confused
