Aspire 750 CPU case button destroyed.
I'm not overly familiar with this model...but assuming its a desktop, try this. Open the side panel on the case and try to find the back of the power button. If you can find it, and there are two wires that come directly from the back of said button, follow those two wires to where they connect to the motherboard. If they run into something else or there are more than two wires connecting to said power button, you may be out of luck and need to get a hold of a new button before you can turn it back on.
I take no responsibility for any slips and mistakes you should make doing the following, do so at your own discretion and beware of possible damage to yourself or your computer.
I used to work in a shop, and when ever we'd get a desktop with a bad power button, we'd turn it on by opening the tower, tracing the wires from the power button to the two pins on the motherboard said wires plug into, unplugging said wires, and shorting the two pins on the motherboard together for half a second with a screw driver. Naturally, I'll tell you to be careful doing this. I'm not responsible if you short the wrong pins and a)fry your computer or b) fry yourself.
Hope that helps and good luck!

White screen fix
only service can fix this ,probably your graphic chip have problem ,service must do reballing with rework station.
No sound out of speakers
(a) Check your audio hardware in Device Manager. A conflict might've resulted in the audio hardware failing.
(b) Check the Volume Mixer in the System Tray. The volume might be down to 0 or it might be muted.
(c) Try putting a pair of headphones in the headphone jack to see if audio works at all. If it doesn't work with headphones, you can assume it isn't the speakers themselves and might be audio device and/or volume related.
(d) When all else fails, try uninstalling the audio hardware in Device Manager, then reboot the PC and force Windows to reinstall the device. That fixes a lot of problems like this.
Post back how it goes!
