Recently my computer froze once then twice, I tried reformatting the drive but it keeps freezing during the isntallation every time ! In addition even though the pc comes on, the monitor does not actually display anything, it wont go to green light. If i will turn it off and then back on enough times it eventually does and windows installation restarts but shortly freezes. Then I have to play with power again for a day for the monitor to come on. I tried both memory chips but it wouldnt come on with either one pulled out. The hard drive seems to spin but am not sure if as usual. It shouldnt be the video card since the comp freezes once it comes on, you guys think its the HD or perhaps the CPU ??
