Hi, i got a new PC. I made it from all retail parts as i will detail later.
However there is a problem. At first the PC worked fine(ok, though irrelevent to this: I coulden't connect to my wireless compleatley and apparantly the 'device on high definition audio bus(or something)' driver haden't been installed when i installed the mobo stuff (I planned to try and sort those things out with re-installation of drivers etc)). But now just a few days into owning the PC, i turned it off last night normally, came to it this morning and it wont boot.
-mobo: Gigabyte GA-P35T-DQ6
-CPU: Intel QX6700
-RAM: Corsair XMS3 PC3-10666 DHX
-GPU: BFG OC2 nvidia8800 GTS
-optical: a CD-drive, a DVD-drive, and a floppy drive.
-PSU: Enermax Galaxy 850W.
- US robotics 802.11g wireless turbo PCI adapter (USR805416)
-cooling: 120mm fan exausht, intel standard CPU fan, 80mm intake fan.
-case: Coolermaster Cavalier (stands upright).
I turn the power on at the plug and on the PSU, I then turn the PC on at the front and nothing happens just a repeated bust of two beeps from the powersupply and a red light at the back.
I looked up that 2-beep and red light thing in the PSU manual, it says it's from "Power supply abnormal, protection circuit activated. OR, Connection terminals are short circuited." I cant think why either of these things would have happened since I have got the PC to work near-perfectly before.
So next I looked inside the PC, I checked all the cables that I plugged into the motherboard when i installed it. Then I turned the PC on again, while the fans connected directally to the PSU started up for a second, the CPU fan that was taking its power from the mother board didn't start at all - not even a nudge of movement.
I looked for google for similar problems, i found that when someone unplugged the power to their motherboard, they found that it made the same alert.
So i conclude that something on my motherboard is screwed up. Maybe a plug from the PSU onto the mobo, maybe a more critical component (capasitor, CPU, RAM, who knows?). Is this conclusion right? Is the mobo where i should focus my attension? Either way, is there a way that anyone knows of that i could test what I have, or sort out the problem - normal installation pitfalls. I need to know what part needs replacing - so i dont have to replace the whole thing!
Also, out of the blue, is there someone who has experianced/overcome this problem before?
PS: 1 - Sorry for any spellin\grammer problems I'm dslyexic and screw up in that department.
2 - If you where wondering, I'm writing this from my mums laptop that I borrowed as she went to work.
There might be a short from the motherboard to the case, perhaps by using the wrong stand-off screws. Take the motherboard out of the case, put it on the anti-static envelope it came in(or a non-conductive surface). Try to power it up with minimum components. ( One stick of memory, vga card )
Thanks loads for the help guys (and girls also if so). I tried it out of the case and with only 1 ram, the gpu, cpu, psu, and HD and it works. I am continuing to add more components and testing them 1-by-1.
As far as I know the Mobo is mounted correctly as my old PC was in the same case - and that worked (appart from the heat killing it when I gamed (hence the new PC)).
I checked for screws and loose things It's all cool, there's none, all seems fine i must have mis-plugged something or something like that.
Again thanks, I am very grateful for your help, I'm happy now .
