Hi. Last night I put my computer in sleep mode. Wake up today and I cant get it to turn on. Ive switched on and off the PSU. Tried plugging the power cord into different sockets with no luck. The green light i can see on the motherboard is not lighting up anymore. Help please! Everything was working fine yesterday.
Well for starters I wish I was there these problems are usually very easily fixed, there are also a number of reasons why a computer won't turn on or wake from sleep including Bios, or EUFI settings, I mean for me personally its hard to say the exact issue, because I build custom stuff and I know the layouts of everything I generally put in my computer.
But one of the common issues that I see is like the computer powers on or won't turn on this can also be related to a short circuit somewhere or even a pin from one of the power supply connectors loose and touching the case itself.
Personally what I would do in that case is if there is a green light on the board, I would Remove every part and inspect everything including the Mosfet, which is another common issue for failure depending on your board, if the Mosfet fail, this can result in the computer working as described too, but not wanting to turn back on, this can usually be easily fixed if you know how to use a soldering iron, and easy to tell if its damaged again depending on the layout of the board there is a heatsink that covers them with thermal pads which can be removed and inspected.
Depending on the price of your computer and what it is to begin with it might be easier just to replace the whole thing, however instead of throwing parts in the garbage, you should at least give them away to someone who knows what they are doing, donate them, leave them by a dumpster, or recycle them, there are always people out there who sometimes have a use for these things, so when I get rid of old things that don't work or are usually outdated I donate them to friends, or leave them at the side of my local donation box and someone usually picks them up...
Heck I walked into a small computer store awhile back, and asked if they had any socket AM2+ motherboards because I was looking to build a friend a new computer with my outdated parts I have laying around but good parts the guy didn't even know what an AM2+ socket was, but ended up handing me a old 2005 socket 939 computer with a failed hard-drive inside, at least I got some magnets for free and a couple of other good parts, including a $400 drive back in the day which really isn't sold anymore but still working.
And yeah of course the problem could simply be a power switch, although I would just test this with a paperclip, or small metal wire does the trick, although my board comes with a secondary power switch / test button to turn the computer on, and I have personally never really seen power switches fail I am sure its possible, and I do have at least 4 extra ones laying around from old computer cases I scrapped.
