    Hey guys,

    I've had a problem with my home build desktop PC for about two months now. Initially there was difficulty booting. Then it just wouldn't boot, I kept getting errors in windows, the graphics card went and came back - but it still wouldn't boot.

    A local technician told me the motherboard was probably faulty - we had also tested for bad ram.

    I got a new motherboard - using the old cou - but when the computer turned on, I had no graphics. I tried changing the graphics card and this again did nothing.

    I've compared both motherboards, used different graphics cards and RAM sticks - is this the result a a bad CPU? I'm using an AMD Phenom II X4. The computer starts - it sounds exactly like it is booting perfectly but I get no picture.....

    Any ideas?

    Aidan.

    First of all, no one [other than you] has any idea what type of hardware we are attempting to diagnose.

    Post ALL of your exact system specs; ie exact mb, exact ram, exact video card, exact pw supply, etc, etc. Do not post "500W pw supply" post the exact brand and model# Do that with all of your parts.

    A CPU is probably the last part I would suspect; cpus are really pretty hard to hurt unless you overclock/overvolt them OR physically damage it during installation.

    The first part I would suspect would be the pw supply.

    Hey, here is the updated information for my PC....

    Motherboard = Asus Crosshair V Formula Z.
    CPU = AMD Phenom II x4
    Power Supply = Corsair CX750M
    RAM = AMD DDR3 1600Mhz 8GB
    Graphics = ASUS NVidia Geforce 210

    How would I know if the power supply was faulty? It is fairly new.

    Best way is to swap in a known good pw supply for testing. There are testers available however they are not 100% accurate.

    Next the cx line from corsair is not designed for any type of gaming, overclocking or other stressful endeavor. It is for a basic build only; even corsair says it is for a basic system;

    Hey!

    I swapped out the power supplies and it worked! The only problem now (is back to an original problem before it wouldn't boot) that the computer is extremely sluggish and will only load into the Guest Account when Windows (8.1) boots??

    Any ideas?

    Just a guess however the user accounts may have become corrupted OR since you swapped mb, you may just have some issues with drivers. In any case, when you swap mb you should [generally] clean install windows, drivers, etc.
