hi, i powered off my pc yesterday, and now when i try to power it back on it doesnt respond as it should. THe power comes on, however it seems like the pc freezes. The moniter doesnt show anything, but the power light flashes on it. Also on the cd drive the light doesnt go off as it should over time. So basically it powers on but icant do anything with it. If anyone has any advice i would really appreciate it.
