Hello all,
I have a strange problem with my current system, I'll try to describe it as clearly as possible.
Current system specs:
Core2Quad Q9400 2.66GHz
1x 2Gb Kingmax DDR2-800
1x 1Gb Transcend DDR2-800
Asus P5KPL-AM
Palit GeForce GTS250 512Mb
Thermaltake TR2-500 500W
1x Seagate Barracuda 250Gb SATA (OS)
1x Seagate Barracuda 1Tb SATA
Running Windows 7 Ultimate x64
Turning the machine on, the CPU and graphics card fans turn correctly, but it does not POST. I have unplugged all of my hard drives, graphics card, and DVD drive, but still nothing.
I tried unplugging both DIMMs and got repeated beeps after starting up - does this mean the motherboard is working fine?
The interesting thing is, if I only plug the Kingmax DIMM into slot A, the system beeps and POSTs correctly, but I can never get past the windows splash screen, it either restarts/freezes there, or it never shows the splash screen after POSTing and the screen stays blank. Plugging the same DIMM into slot B also causes the screen to stay blank.
Inserting the transcend DIMM into either slot causes the startup beeps to disappear and the screen simply stays blank.
I tried testing the voltage levels on my PSU and the 3V, 12V and 5V standby are all correct, although the PSU fan is not spinning. Which is confusing, since the system can POST fine with 2 hdds, plus a fairly power hungry graphics card, leading me to believe that the PSU is fine, plus it's not even a year old. I have not tested it with another PSU though, don't have access to one at the moment.
Could it mean that one of my DIMM slots somehow got damaged? Perhaps from incorrect voltage from the PSU - how likely is that? Or is the PSU the only problem? Can it be related to software? Seeing that I have tried running startup repair but it freezes after a couple of minutes.
Thanks for your time
Jaco
