I HAVE NO IDEA WHATS GOING ON

[flowone_uk]

hiya, been a little while since i last logged on hope you guys can help with this.

i have built a new gamming rig, first the specs (no over clock yet btw)

Fox con Black ops mobo
Q9550 cpu
4gb ddr3 corsair dominator memory @1600mhs
1tb samsung spinpoint f1 hdd
akasa 4 way fan controller
ati 4870 gpu
3.5" drive bay reservoir for waterloop cooling cpu and fsb for when i start the oc project

i will ony oc the cpu so the drive bay res should be enough for this small loop
and i have done a full 72hr leak test just to be safe

anyway heres the prob 2 out of 10 times the monitor wont pick up a signal. i have to switch off unplug the psu (be quiet pro @650 btw) then try again. sometimes this will sort it out on the first go but others i can be at it for half hour before getting anything.

my origional thoughts were
1) a faulty connection somewhere so i stripped the pc and rebuilt it... no joy!
2) monitor fault, i dont have another monitor to try so this is still a possibility i guess
3) mobo. i returned it and the suppliers said there was a fault so replaced it, at the time this was a biostar tpower I45 when i got it back 2 weeks later the same thing happend so i returned it again and got it swoped for the foxconn but now funny enough 2 weeks later im getting the same challange
4) gpu again still a possibility but i dont want to keep pulling out parts payiong for postage and waiting what seems like forever for these components to be checked and replaced i have sold my old rig so i cant check on another pc

I have just noticed that when the monitor does pick up a signal i get a single beep which i believe indicates a successful P.O.S.T when the monitor doesnt pick up signal this beep doesnt occur the pc just powers on. i do hear some clicks like the cpu is working at something and the fans and water loop pump kicks into action but nothing else

im currently running windows 7 hp 64 afetr upgrading from the same spec vista and this fault also occured on the old O.S

PLEASE HELP.... THE MISSES IS GETTING MAD, she wants her facebook back

Try a CMOS reset and loadiing otimised defaults - then bump up the MCH (North bridge voltage) up a couple of increments. You're using all the DIMM slots which puts additional stress on the memory controller and as a result it sometimes requires more juice to keep the system stable (or even boot/post).

You could jump straight to the MCH voltage tweak - but if it fails the first time try the CMOS reset and then reapply.

Additional: If the MCH tweak doesn't work i would then try bumping up the memory voltage by 0.1V - as the same principle can apply with the memory voltage when using 4 sticks.

It may be that your system requires a combination of both: a MCH increment plus a slight memory voltage increase - *if* lack of memory juice in all its forms is the problem...
