I've taken a look all over this forum for a problem similar to mine, but I can't seem to find it. Here's the issue:
My computer was working just fine until last night, when my girlfriend started it up and it did not boot up. All the fans came on, and the light on the tower was green, but the monitor stayed black and nothing appeared. She said after about a minute, she started smelling "rubber" and immediately turned the computer off.
When I came home I took a look at it. I turned the computer on, all the fans came on, but the light on the tower is now yellow, and the two disc drives will not open, like they're not powered. However, there is a power light on the drives, so that doesn't make much sense. I turned it off and checked all the connections inside the computer, unplugging each one and then replacing it. There are no connections missing. I did the same for the outside, and checked the surge protector. I also did not smell any rubber, and didn't notice any burn marks anywhere or any external damage to the motherboard or HD.
Here's what I'm assuming: since I do not get any startup screen of any description, the problem lies with the motherboard. What makes no sense to me is that there are green lights on my disc drives, but they will not open. That has be confused. If it were the HD, wouldn't I get a startup screen showing my ASUS motherboard screen and access to BIOS, but then a HD error? If it were the PSU, there would be no lights on my disc drives and motherboard (which there are), and the fans would not come on. What does the yellow light on my tower mean?
Are there any suggestions that can be made, any tests I could perform, that could validate my suspicions, before I pay for a new one motherboard and find out that isn't the problem? Thanks for any help.
