Facing the front of the computer, lay it on its right side and prepare to remove the left side.

Remove the two larger screws at the back corners to allow the left panel to be removed.

There is a black knob near the lower screw that operates a latch.  Push that knob toward the bottom of the computer and remove the panel.

If you look at the back of you computer tower you should see 4 screws, one at each corner. Unscrew those one side at a time and that should allow you to examine the inside of your computer. Be careful when poking around because static electricity may short something out.

Hi i recently had a BSOD pop up on me when my Windows Vista from my Acer AST690-UP925A was starting up. theres also a status code for 0xc000000f with file: Windowssystem32configsystem from the windows boot...


I would recommend that you do a repair install off of you Windows Vista CD because it sounds like one of the Windows system files got corrupted.

If this does not fix the problem then you are looking at a reinstall of Windows.

Let me know if you have any more problems or questions

How do i remove the front panel to change CD/DVD drive? I do not have a manual for my desktop - I can remove the side panel but not the front panel. thanks you

You need to remove the side and then remove the front. The front is connected by latches which are on the top bottom and opposite side of the machine. Once you do that the drive should slide out the front of the machine. You may need to use a flat head screw driver to get the panel off.

Acer Aspire AST690 won't boot, just beeps. Nothing on the LCD. Fan is spinning but that's it.


This is an Hardware Failures: Doesn't Boot Up.
First of all, most of the hardware failures that are going to be presented in this article require you to disassemble the laptop and work on its internal components. Because of this, you need the required components to take the laptop apart (such as screwdrivers, etc.) and space, lots of space. If you don't have a workbench, then working on that large table in the living room should do it.

You need to check the memory stick this is the first to diagnose the problem of beeping. Remove the memory stick clean the dust, and reinsert the memory stick, try to use the other memory slot.

Thanks for using fixya

Computer won't start up and has a constant tone.

If the noise is constant then it means the problem is either:

1: a Power supply issue
2: a motherboard issue
3: a keyboard problem

the latter of the three being the easiest to fix, try booting with your keyboard unplugged or even better if you have another keyboard try using it to see if that corrects the problem.

If the above does not work then you have a problem with 1 or 2, and in order to find out for certain you will need to test it, you can goto your local computer diagnostic store to see if they can check which it is.

and hope its not a problem with the motherboard.

Hope this helps, and Good Luck
