Hello,

I have an Acer Aspire AM3100 Desktop. I came home to find my computer power was on but there was nothing on the screen. After messing with it for awhile, I realized that I can turn on the computer, which turns on the fans and the disk drive but nothing else. Any ideas?

Thanks
Kevin

Maybe something wrong with the mainboard.

Sorry for the delay in replying to your OP mrbojos but as you had received a reply it appeared you were receiving assistance already.

If this is a desktop then a bad PSU or video card (if one is present) may be the cause.

Please provide information about your computer, this includes is it a notebook or desktop, is it a custom build or brand name such as Dell or HP, if it is provide the model name or series number (not serial) providing these details will enable others to better assist you.

It is an Acer Aspire M3100 AM3100-u3300A Desktop. I hope this is enough info because it is not much more than in my original post. When I turn on the computer the fans come on and the DVD burner will eject but the hard drive doesn't seem to work. There is no beeping like it normally does when it starts and no signal going to the moniter. I tried installing a new PSU but it did the same thing.

Thanks for the additional details

Are you using an add on video card or the MBs integrated video chip?
If an add on card remove it and try the integrated video chip.
If you do not have an add on card try removing the Ram and powering up, do you get any error beeps?

Be sure to disconnect the power cord from the wall and take anti static precautions by touching a bare metal part of the case before reaching inside the case,

My computer doesn't have an add on video card, so my is running on a MB integrated video chip. I removed the RAM and powered up and got nothing but the fans and DVD burner running. No beeps. Also, I discovered that my hard drive is running. It was hard to tell until I took it out and felt it running. Oh, also I tested the monitor and it checks out good.

This doesn`t look good for the MB, the CPU or worse case scenario both
Do you get a BIOS screen when you power up?
Have you tried tapping the F8 key when you power up?
Have you tried clearing the CMOS by removing the MBs CR2032 battery? (see .jpeg)

I tried the steps you suggested with no luck. So I broke down and took it to a computer store. They called a few minutes ago with news that my MB was shot!

Thank you "Rage (against the machine)" for all of the suggestions and help.
