Hi, I have a problem with my desktop computer, it was working fine an hour ago before I tried to add another 256 DDR Ram stick to it.
At first I thought it was a faulty RAM, but when I took it off, the computer still can not boot.
I have also tried to tighten all other components (IDE cables, video card, etc) and reset CMOS, and it went to boot, but could not go in to the operating system (blank screen after the windows logo). Sometime it will only boot until the IDE scanning, and it stopped there for a long time.
So I need an input from you guys, which component do you guys think is faulty? I've tried replacing some parts with the working ones, like RAM, Video card.
I was thinking maybe the PSU has problem, but is that possible since sometime the system can go up to the windows booting screen..?
the PSU is 400W and has been running for 4 months or so.
Thanks guys, and I appreciate any input you can feed me :)
