dead CPUs spray-painted memory dead power supplies is there any way of testing and fixing these things let's find out ladies and gentlemen welcome back to tech yes City today I've got some of those crazy experiments coming back at you and the first one is the stick of memory that I spray-painted sometime last year now I just finally got around to taking stripping the paint off and then putting it back in the system and testing whether it works again so let's get onto that experiment okay so here's the moment of truth with the one gigabyte stick let's do this yeah so that's a memory problem so the RAM is not being recognized so if we're working one gigabyte ddr3 stick in as we can see here we've got seven gigabytes of ddr3 memory because it's working alongside another six gigabytes of ddr3 memory and we're going to put in the paintbrush now fully cleansed Ram stick and see if it still works I mean how tough is that I mean I've got seven gigabytes of ddr3 memory guys I'm running lucky serpents place you'll be unique on the internet no one will be able to copy you anyway let's check if this bad boy works okay system info motion seven gigabytes of ddr3 memory whoa okay whoa I'll stick Lou has come back well we're dead well so what we're going to do now is we're going to try one more test with this one gigabyte of ddr3 memory stick we're gonna wash it with water and soap and see if it still works okay so here we go we're going to start putting some soap on and this is probably the part where you guys are watching this video and going what the actual am i watching so don't worry guys it's all in the name of enthusiast tech you know when you came to tech es city you knew what you were getting into brother you knew oh you knew so here we go we're going to scrub this down give it a good cleanse and then we're gonna see and I'm gonna wash it the course gotta I don't know man you can give this a hot wash a cold wash whatever you want to give this ddr3 memory stick your flavor let's give that a nice good wash there and we will start hair drain it you know put a hairdryer on it and get it all dry so we can quickly get the excess water off with some tissues and then we're going to drive so the moment of truth is upon us we are going to now test this nice fresh and so clean can be a stick of memory after it has been under the tap and also bundled with some soap detergent and a brush so and under a hairdryer too so just how much of a beating can some PC parts take I don't know this whole little bad boy has been through hell and back I mean he's been under paint 7 I didn't even know how many different coats of paint I put on that and then he's been cleaned with water he still works ladies and gentlemen he still works so 7 gigabytes of ddr3 memory is being confirmed here so the stick is recognized again and that is some wicked news it means you can wash PC parts but so the next experiment we've got going on here is a dead CPU specifically a dead CPU with resistors that have crumbled off the back of the CPU now in my case this did not work at all I had a circuit writer and I did a pretty careful job of connecting this circuits back up however when I installed it again there was just no signal whatsoever so in the case of the dead CPU I'd recommend maybe getting some original resistors that aren't broken and trying that if you can but keep in mind that a warped die is pretty much impossible to bring back to life so the next experiment we've got up here is a dead power supply and without further ado let's get onto this experiment ok so testing and dead power supply and seeing whether it's truly dead or not comes down to actually testing it itself now when I turn that on the fan quickly spun up however you can see now if I try to turn the motherboard on now there's just nothing happening so essentially this power supply is damaged somewhat somewhere internally I don't know it looks like a short since it just actually got something a little out to the fan and it just doesn't work so that's how you actually truly test the dead power supply not is actually by plugging it up to and cheap components if you can so it's always good to keep something like a and a motherboard around your house just to check power supplies that would be something I would suggest because testing a power play like this on a cheap motherboard and opinion and one gig grams of sticks and a GT whatever this is I've got nothing to lose here really so this power supply is bricked and we can chuck that in the bin so the fourth and final experiment is can you use a PCI Express port to power your hard drives let's find out so on this next experiment we've got a power supply which has no molex or solder connectors on it so I'm going to try and use a PCIe 2 PC a female and then a PC a - molex to molex to molex female and then a molex to a SATA connector and see if that powers on the hard drive because I want to be able to actually make use of this power supply in a real-world scenario so if this kind of works then we should see success so let's boot up the computer so what happened there John trusty file there we go and we're going to see if it boots up and then we're going to go into the BIOS and check if the hard drives in there okay so we're in a set up now and our trusty little hard drive is not being recognized right so just going to try up a DVD DVD ROM or a DVD random DVD writer whatever now not getting recognized so I guess it's soldered to whatever it is side of the side of the side of the side of the molex just doesn't work so there we have it guys all the experiments and the biggest one that surprised me was this stick of memory here this little one gigabyte stick of ddr3 memory it survived some really harsh conditions I actually left it outside for a couple of days as well when I was using the parts cleaner on it to strip the paint and it still survived it survived a brush soap washing hairdryer and still works so I'm pretty surprised and I guess the verdict on that is is that you can wash PC parts just be very careful to make sure that there's no charges left in any of the capacitors or anything like that so the next experiment we had was the CPUs and in general if your CPUs have been warped from either too much heat and or too much voltage and they usually go hand-in-hand then your CPU will no longer work just keep in mind though the CPUs do have sensors on them and thermal protections however they don't always oh they are always a perfect safe fail just keep that in mind because the sensors aren't located all across the die and it only takes one micro part of that chip to overheat and warp and you've got a dead CPU and this applies to GPUs as well then we have the power supply experiment and as you can see this power play wasn't working and the easiest way to test for that was to use a test motherboard and CPU and one stick of memory now the cheapest way to have a test set up would really go to pick up one of those old Pentium 4 systems then you can get for like 5 bucks and use that as a tester maybe of one of your friends or leave it in your friend's garage or whatever just for testing power supplies as you can see in this case it did let out a bit of power when it first started up but it didn't power on the computer at all so that's the definite way to test for faulty power supplies then the last experiment I had for you guys was the PCI Express port from a power supply powering hard drives and that just didn't work flat out no power going to either the hard drive or the actual DVD drive that I tried now the good news that came out of that was that the hard drive or the DVD drive they both didn't fry they both still worked when I plugged them up to my other computer and now for the final last experiment and this is how to discharge your power supply so there if you turned off your power supply and you want to clean it and you want to make sure that there's absolutely no power left in that power supply and you can do the tackiest city method and that is put on an insulated glove and get yourself a file with a plastic handle and let's just make sure those connections are letting off no electric discharge at all so anyway that's all for today folks if you like this video then you know what to do hit that like button and also subscribe if you haven't already for more technique of using whatnot and I'll catch you in the next one pace out now but
