Hello fellow hardware junkies. I have been interested in computers for many years but have recently stumbled upon a situation where I'm a little unsure what to do next.
Recently my set-up has been acting funny. By this I mean I would press the power button and the system would turn on for 2-8 seconds before shutting off (nothing shows on the monitor). The only thing that happens is the fans spin for this time. If I kept pressing the power switch it would eventually boot. Normally, I would have tried to determine the issue but it was the end of my semester so I just left my machine on so I could continue my work. Also, sometimes when trying to run games the machine would power off suddenly.
Currently I cannot seem to get the machine to power up and remain stable at all. I'm unsure if it's the PSU or my graphics card or the PCIe slots on my mobo. If I do not plug in my graphics card the system will boot which leads me to think its my GPU. I do not know, however, if the GPU could be overloading my PSU and perhaps it is the PSU after-all. My card needs a 12V rail. I don't have any other hardware to test with and I plan on getting a new PSU tomorrow as it's a cheaper check.
I was just wondering if anyone here has had similar problems. I cleaned out my rig today and put it all back together with fresh thermal paste in case it was overheating but I'm still getting the same issue. I don't mind replacing one of the parts but I'm at a loss as to how to narrow down the problem some more. It seems as if the board is shorting because it no longer stays on for 2-8 seconds, the fans spin for about one rotation before the system shuts off again. My PSU light comes on for this time, and remains on if the GPU is not installed. I checked the 12V rails with a multimeter and they are putting out the correct voltage. I've also tried powering the card while not installed into the PCIe slot. This does NOT cause the system to shut off, but I have no display. It's only when I plug it into the PCIe spot that everything fails (I've tried different PCIe slots with similar results). Sounds like the GPU to me but I would like some more opinions.
The system is a bit dated at this point.
Specs:
Mobo: MSI P6N Diamond
CPU: Intel Q6600
GPU: BFG 640MB Nvidia 8800GTS OC
PSU: BFG 650W (BFGR650PSU)
