Hi all!

I really need your help here...

I bought a new pc and built it up and actually managed to get it running. My problem is that when I was installing the windows and the machine had been running smoothly for ½h the screen went black and it seemed not to give any signal to the display at all, but the machine was still running. I booted it and it wont start up again.

Or actually, it starts, but there is nothing on the screen. All the components are working (I think) all the fans are running, it seems not to have any faults. But there is nothing on the screen, it does not start. When it happend, I opened the case and looked for a problem, I did not see one until I noticed that one screw had fall of the MB and another was loose. (these 2 screws did not tighten when I mounted the MB, so they were hanging loose from the beginning). So I took the screws away, tightened them with new ones, that worked and tried again, the pc did not start.

I loosened all the components besides the cpu and cooler and mounted them back again and tried, same story, no picture on screen, nothing.

So, short, my new pc is running great for ½h-> the screen goes black->I find 1 screw loose and one that had jumped off -> the pc does not start up anymore, but all the components seems to be running good.

The specs are:

CPU, Intel Core 2 Duo E6300, 1.86 GHz, Socket 775
+ Noctua NH-U12F cooler
VGA, Saphire Radeon X1950XT 256MB GDDR3
+ Arctic Cooling Accelero X2
HD, Seagate Barracuda 320GB
MB, Abit AB9 socket 775
Mem, Corsair 2x1G
PS, Seasonic 500W, S12-500W
Case, Antec Performance One P180
+ Samsung SyncMaster 206BW 20"

Did something broke? Did the screws have anything to do with the problem? Should I try to change the MB? Have any of you guys any idea what is going on?

Thx in advance!

You may have shorted out the motherboard with those loose screws.

Did you put all the brass standoffs in properly? Are you using the right screws from the little bag that cane with the case?

Maybe time for a rebuild 8O
