Does this sound psu related???????????

I have recently transplanted a motherboard (gigabyte ga-ma790x-ud4p) which was working fine with my Phenom II 720 (see overclocked stats in sig) and memory at 1080mzh in another computer. I replaced a msi board in my sons computer with the gigabyte due to me buying another amd based motherboard (wanted sli compatibility and more memory flexibility). Problem is I have installed a AMD Athlon X2 5000+ be which was in sons computer (but on a msi board) in the gigabyte board. The processor had been running stable before in the msi board at 3100mhz but had speed reduced recently to 3000 due to erroring out in prime and the video card (gtx 260 core 216) sometimes just going black and not coming back on while computer was already running. Reducing clock to 3000 made everything tick properly in the MSI board but now on the Gigabyte Board (same everything just transplant) for the life of me It wants to stall on a cold boot above 2800mhz. Cpu is 2600mhz stock. I have tried upping vcore, no change, swapped out my 275 which is in my system, booted up fine at 3000 for about 7 tries then started not wanted to boot cold again. Tried 2 sets of memory which both have recently proven stable memtest and prime 95, no matter whether the memory was below stock mhz or not still cold boot above 2800mhz cpu speed. I went as far as unplugging my dvd drive from IDE controller (yes i know its anchient) and removing the wireless network card, still with those out of system above 2800 not boot (or if boots have to turn of power when it gets stuck at boot with no display then it will boot properly next time)

I also tried putting my phenom II 720 which has been running in the gigabyte board with same memory it was paired with previously (and had been working properly together before transplant) and dialed in oc setting that I have been using for about 3+ months up until last night before transplant and were prime 95 linx all stable 24+ hours. This setting would not cold boot either (same CPU, MEMORY, MB, Video Card, just in different case with different dvd drive, hard drive, and power supply) The only thing I have'nt swapped out is hard drive (due to not really wanting to reinstall vista just for this test and not having another one that I can wipe clean and install vista on to test on sons computer) and power supply...... all things else I paired up exactly like they were in other case, still above 2800+ no boot.

Does this sound power supply related, and If so could a faulty power supply have difficulty booting system but run 20 passes of linx max memory just fine. I had burned in cpu yesterday at 3075mzh with memory at 900mhz and it tested fine on a short run. It was'nt until after I shut down computer to reboot it that it starting giving issues. Also what should I use to test PSU from within windows if I cant easily change it out for another one????? OCCT power supply test? Or can a hard drive cause cold boot issues too? (when I say cold boot I mean failure to even post screen that says hit del for bios)

any reply would be greatly appreciated.

Get it running and download Sandra lite from somewhere like Guru3D and it will give you many bench options to test with for free.Good luck

Maybe I tried to explain too much in the first thread and I really did'nt explain my main concern. The dual core was overclocked to 3000+ mhz in another mb, a cheaper 780g based msi board, in sons computer. I took a board which had been running a 720be tri core at 3550+ mhz and put it in my sons computer and installed the dual core in that board (gigabyte 790x chipset) After putting my board in his computer and installing dual core in it started having problems cold booting over 2800+ mhz. The Dual core was fine in another board (the msi board), and the board (the gigabyte) was fine overclocking a tri core to 3550, so my only logical conclusion was it had to be either the newer bios (only 2 are available) somehow is optimized for the newer processors but dont support overclocking much on a old dual core, or the power supply is starting to go. That is why I asked if the cold boot issue could be power supply related, it seems to get stuck at post before the screen which says gigabyte loads, and fan ramps up and down quickly like someone revving a engine. at below 2800 it post fine (default speed for the 5000+ be is 2600mhz)

Not a total noob to overclocking but I did'nt really run any benchmarks on machine before so I dont have anything to compare it to so Im not sure how that would help. Also on a side note When I first installed motherboard it posted and I ran LinX at 3075 mhz, It ran 20 passes max memory fine, it was not till I turned it off that I started having problems posting.

maybe the old board is a better overclocker man have you tried raising the vcore a bit?

to be honest, i have a gigabyte board MA770 UD3 and it doesn't really like to OC. i've even tried two different types of ram same issue. i've came to being content with a mild OC and a super stable board.
