I have an old NEC that was working fine. It's been doing this thing again that it did before and I have no idea how to fix it. I assume it might be a common problem because I took it back to best buy a long time ago and they were like there isn't anything wrong with it. Well anyway it has a Pentium II 350 chip in with 2 kingston ram chips. When you turn it on, the bios won't come up it just stares at you with a blank screen. I know it's not the video card and the post just won't start. Any idea what this could be or how to fix it? I've been having it off and on for a while and can't seem to figure out what it is. The hard drive will turn on and everything but no boot up beep and it stops before starting the bios up? Thanks in advance.
