High pitch screeching on my pc cannot fix thru speakers check ok

Unusual noises coming from your computer can mean anything from serious trouble to no problems at all. The uncertainty, together with the expense of computer hardware components -- not to mention the risk of losing data and being without your computer -- make it important for you to investigate any unusual sounds as soon as they come to your attention.

Normal Sounds
Not every high-pitched sound coming from your computer suggests a problem. Computers also generate a variety of sounds as part of their normal operation. In particular, anything that spins can easily make noise. This includes cooling fans and the hard drive. In the case of fans, their sound sometimes grows louder when the computer works harder because it needs to run the fans at a faster speed in order to dissipate the extra heat from the higher level of operation. You probably don't need to concern yourself with an unknown high-pitched sound unless you have used the computer for a while and the sound is new. b> Capacitors Capacitors sometimes make a high-pitched buzzing sound, either when under a high load or when defective. In the latter case, faulty construction can cause gas to build up inside the capacitor, which then vents under pressure and sometimes creates an audible noise. Defective capacitors can damage or destroy other hardware. f you suspect a bad capacitor, or don't know what else it might be, give your computer an inspection. b> Capacitors Inspection b> Your computer has capacitors all over it, including on the motherboard and on nearly everything that plugs into the motherboard, so tracking down a bad capacitor can take some time -- especially if you don't know whether a capacitor is actually causing the problem. Many capacitors look like tiny little soda cans and smaller ones look like squat cylinders. Failed capacitors usually bulge out at the top or have crusty residue around them. Be sure to check not just the motherboard but also any other hardware components with visible capacitors on them. If you find a bad capacitor, keep looking in case you find more. Afterward, don't use your computer again until you repair or replace the faulty hardware. Fans b> The bearings and motors on fans sometimes go bad. If this happens then the fan may begin to whine, whether or not it stops working. If feasible, open the side panel of your computer tower with the system running and try to pinpoint the exact source of the sound. If you can determine that the noise is coming from a fan, power down the computer and replace that fan. b> Power Supply Unit b> Power supply units sometimes make a high-pitched whining or droning sound; it can happen continuously, when you perform certain tasks on the computer or when you take the power load high enough. This can happen either because of cheap construction or because the unit is too close to maximum capacity. As you would do to check the fans, open the side panel while the computer is running and put your ear up to the PSU. If this is where the noise is coming from, replace the unit with a high-quality model and upgrade to a higher power output if you need to do so. Hope this helps.

Acer aspire x1700 black screen, makes high pitched noise, doesn't respond

You may have damaged or dislodge a component.
I suggest you remove the cover and reseat the RAM modules and all the cards in the expansion slot (unscrew them pull them out of the expansion slots and insert them back then secure them with the screws.
If it still does not boot up then you need to take the computer to a computer repair shop.
