my computer restarts randomly these days. i have been compelled to remove the newly added RAM to run my computer. i had 128MB DDR RAM previously, after sometime i added similar RAM module in the next slot. computer starts normally at first. but it goes off or restarts somewhere in the middle. system runs very slowly with only 128MB memory. i've got a massive project to complete in a weeks time. can anyone please help me. i am new to this forum.....i found it quite interesting. please please help me with this. i have tried with 4/5 pieces of RAM modules. it's the same story everytime.
