My compaq laptop does not load the windows OS. First, when i was using my laptop, it shows the blue screen telling about physical memory dump error. After that i swithced it off. When i switch on the laptop again, it only display blank black screen. I repeat the same thing for some times for few days, it is still the same. So i decided to press F8 while it is booting and i go to 'Safe Mode', but still i only got the blank black screen. I tried to use the repair CD to repair, but it doesn't reboot from the CD. Its veri weird i think and 1 more think, the harddisk indicator light does not blink or turned on as usual. Could it be harddisk problem??? How to fix this problem?????
