You didn’t specify how far you got after swithcing it on. You could try Performing a Start-up Repair: The first thing you can try is booting into the recovery environment, if possible, and then performing a start-up repair. To access the recovery environment, turn your computer on and off three times. While booting, make sure you turn off the computer when you see the Windows logo. After the third time, Windows 10 will boot into diagnostics mode. Click Advanced options when the recovery screen appears.  Click Troubleshoot.  Click Advanced options.  Then, click Start-up Repair. If you can’t get this far your hard drive may be corrupted If so try booting with a USB flash drive with with the Windows installation files on it, as drmdolfan suggests.

Sorry, no you can’t. Not really worth it with the RAM limitation. And, hey, it’s 11 years old. I have the ACER Aspire One and it is the same problem.

Disconnect battery - don’t take out: https://www.youtube.com/watch?v=AmTCoLq7... Then see if works with only charger/powersupply plugged in. If Yes then replace battery.

Go for any board with the B550 chipset as it supports PCIe 4.0 and will support the new amazing 5000 series Ryzen CPU's. This will enable you to upgrade easily in the future saving money.

Disconnect the main battery connector, as shown in step 4 second photo, but don’t bother removing the battery, ASUS ROG Strix GL503VD-DB71 Battery Replacement then remove the CMOS “coin” battery to the left of the main battery and press the power button to discharge all power from the system. Put the coin battery back, plug in the power supply/charger and turn on the computer. Does it come on and stay on? If yes then shut off, correctly, unplug power supply and reconnect battery. Does it still come and stay on?

Yes. The term they use is “dual” voltage meaning 110-240volts. All you need to do is change the "figure 8” mains voltage power cable.

If you have a turntable it is easy to move to computer.

This is the one I use because of the pre-amp stage. Not all amps have the phono preamp. There is freeware software such as Audacity that can remove the clicks, etc. ALWAYS make sure you backup the recoding several times incase you make a mistake while learning how to use Audacity or which ever software you select. Audacity is best if you zoom in and mute rather than delete the click. Deleting the click produces a timing error which is noticeable, you don't seem to notice the mutes. You will need a lot of patience, some commercial software removes clicks automatically but the results can be a bit hit and miss, it depends on how fussy you are. (Thx to anthony david...

Please, people, STOP buying these proprietry external hard drives. You are juast asking for trouble. They are neither upgradable nor, easily, repairable. The internal interface is not standard. Get a good external case with a USB 3.1 controller and a standard SATA HDD or better still a standard SSD. Most models open very easily, some even are water proof. If either fails it can be simply replaced. Drive upgrade is just a simple pop out and pop in new. It will work on anything with a USB port.

@louise1948_29 Hi Louise, Here is what you must do. (1) Check amperage of heater - look on plate on back of heater and it wil state voltage and amps. (1) Check amp limit of extension chord. (1) Check amps of circuit - look at fuse or circuit breaker for outlet - important to check rating of circuit as some one may have incorrectly used a higher rated fuse/circuit breaker. It is strange that the fuse/breraker didn't trip. All three MUST match or you could burn your house down. You know some circuits may just be wired for lamps. So check!!!! Having done all the above yes you may rewire the plug but make sure you get the polarity correct. There should be a little diagram, etc. with the replacement plug.

Probably a compatibility issue. Mac are very fussy with everything. Crucial has a MAC memory guide chart: https://content.crucial.com/content/dam/...-products/mac/flyer/crucial-memory-for-mac-systems-compatibility-chart.pdf?cm_mc_uid=34343255512516056658...|www.crucial.com=86343901605665859230
