I was playing a game on my PC today when it suddenly just turned it self off and now won't turn back on. I have tried useing the power supply connected to another computer in the house on my computer and it wouldn't turn on.
I beleive this is the 2nd time this has happened, last time I took it to get fixed and he simply said I needed a new power supply so I bought one. I have only been using those power supplys that are simply a cord plugged into the PC.
Another thing that has been happening (not offten) is when im playing a game the PC would crash to a random colour screen ( be with pink, green, light blue) with a 'bzzzz' noise. However this only seems to happen once and once I restart the PC and start playing again it would be fine.
So any idea what the problem is? Really wanna get some opinions before I drop it off to the PC guy and cop another $100.. Just to look at it.
Your power supply is at fault once again. I have a feeling this "PC guy" may be ripping you off, $100 for a power supply is quite a lot but the question is what brand are the power supplies he installs for you? and how many watts? Let us know you computer specs to see how much watts your computer utilizes in the first place.
So you think it is most likely the power supply? Not the motherboard or something else?
The power supply in there is an A1-5000 - Aywun. 500 Watts it says ("MAX POWER 500W") However below it on the sticker it says: Note: +5V and +3.3V total outputs shall not exceed 220W, whatever that means?
Unfortunatly I am unable to gather my computer specs as I can't get it running. I can tell you though that it does have a nvidia Geforce plus (i think plus) video card in it, and it is capable of running all new games such as Sleeping Dogs etc (aslong as those crashes I described in the OP arn't anything to do with the grapichs card). If that helps..
Well there is your problem, you pc guy has been ripping you off with power supplies that cost dirt cheap and are made with really low quality parts. A good quality power supply would have at least more specifications on the website, I mean look at the link below http://www.aywun.com/ProductDetails.asp?ID=59
Do yourself a favor and avoid your PC guy, buy a power supply yourself and install it (or get someone else to), buy Antec, Corsair, XFX, Seasonic, Pc Power and Cooling and top tier brands. Try taking a look at these good power supplies that actually provide that wattage they label:
Corsair is generally a good brand, it is quite easy to install a power supply. All you do is unscrew the old power supply from the case, remove all connections it has on components and then slide it out. To install just slide it in place, screw it in and connect the connectors in the right place. It is possible for a power supply to cause crashing with fluctuating voltages and in general its usually a low quality power supply. To determine a safe power supply that meets your wattage needs then I need to know you computer specs or just give me your computer model if its an OEM one (you bought pre-built at a store).
Just calculated your wattage, this is a general approximation since it was calculated when your build is at 100% load which is rare. Anyways with 10% capacitor (fairly new power supply) your computer uses 427 watts. This build may have been stretching your previous power supply that was cheap which is why it gave up. I bet it could not supply 416 watts. Anyways my advice now is to buy a 500+ watt power supply just to be on the safe side for future upgrades.
