Hello,
I've been using this machine and got an issue that maybe someone can help. This machine suddenly goes to blank monitor and i turn it off by long pressing the power button. When i try to turn it on i've got red blinking 5 times. I've check this issue and it says that its the pre-memory problem and i have to to switch the ram to other slot or change the ram. I've switch the ram to other slot but still i got the 5 red blinking, so i decided to buy new ram. Sadly, i'm still got the same 5 red blinking. Friend of mine told me to unplug the machine and leave it for more then 24 hours and try turn it on again. He got same issue but don't know whats the problem. After i did what he said, yes i can turn it on again and used the machine without problem until i turn it off again and same issue came back.
For your information i'm using Windows 7 with 2g of ram.
So, anyone can tell what actualy the problem and solve this issue?
