Hi ALL!

i need help. i have just completed my new build.. first for the specs!

Biostar T I45 mobo
Intel Quad Core Q9550
Corsair Dominator 2 x 2gb ram
Be Quiet! Dark Power Pro 650w PSU
Samsung Spinpoint 1TB HDD
Sony Opteron DVD Drive
XSPC Drive Bay Reservoir
XSPC 120 Radiator
XSPC Delta V3 CPU Water Block

THE PROBLEMS!!

when i switch the computer on it restarts itself twice! then powers on the third

the mobo is not recognising 1 of the 2gb ram moduals

i just restarted the mobo and it bluescreend on me then restarted and it was fine

Also whenver i restart the pc doesnt power off completly before powering back on not sure if thats standard but all the other pc ive ever had powers off then on when restarting

PLEASE HELP!!
 
Well it sounds like a faulty RAM stick.

Ok, first things first, try one stick at a time, see if that works.

If not make sure you are using the correct VDIM (voltages ) and the timming are set to auto.

Try again.
Lastly get memtest86+ and test each modules, this will soon pick up any problems.

edit - I also see that your water cooling.. Did you run a loop test for 24 hours or so before powering on the PC?

it does look as if its the ram i'll try what you have suggested. i leak tested for 48 hours. tissue round the barbs to insure no slow leaks. i think im just real stressed and not thinking correctly. this is my first water cooling build and its made me a little nervous lol
 
ok heres the latest!

I have removed both ram moduals and inserted one at a time in different slots.

the pc then didnt reset itself however there was no graphics the monitor continued to flash as if no cable was inserted. i took the graphics card out reinserted and nothing i then put the ram moduals back to how they were before and re inserted the gpu again (its a sapphire hd4870 btw) pulled the battery on the mobo and it restarted about 5 times and now its up and running again (on the 4th reset i got the blue screen of death again!):confused: any other ideas
 
Was ok on at least once stick.. try different bank/single stick combinations too.

Did you check the VDIM and the timings?

Are all the 24 ATX and 4/8pin ATX connectors secure on the mobo

heres the lateset!

i have tried removing the ram moduals and inserting one at a time in different slots! when i switched back on i had a reported AMI Bios code stated that the pc was awaiting a graphic device and the monitor would not switch on! i tried removing the gpu (a saphire hd4870) and reinstall but with no joy. i had to replace memory back to its origional slots (both needed installing to p.o.s.t but i beleive thats normal with this cpu) then reinstall the gpu afte pulling the cmos battery it posted but again reset 3 times bluescreened on the 4th and powered up sucessfully on the 5th. im going to try using my old ram now to see if that makes a difference. i also used vistas memory diagnostic tool for reported errors on my current ram but it didnt find any. i will run the mem test previously suggested and if that doesnt work then swap rams i think!

ANY FURTHER ADVICE GRATELY APPRECIATED

:confused:
 
I had problems with the same Biostar a few month ago with the HD4870.. which was doing the same thing.. I flashed the BIOS and that did the trick but it still sounds like you have a memory problem.

Make sure your BIOS is updated.

then, for now, make sure the memory mapping in the BIOS is disabled.



does that cure the video problem? Retry the previous tests. then check the memory using memtest86+.. try one stick at a time though.

Tried known good ram from my old rig and got the same problems mem check shown no problems with both sets of ram and I've had to put the origional ram back in to try and get a display on the minitor... Nothing! Tried a known good graphics card from my old rig... Still nothing. I can't even get a p.o.s.t on my new rig now so I think there's a fault with the mobo... Before I rma it does anyone have any other thoughts. I've been building pc's for a while now and never seen this before but I've never had the misfortune of a faulty mobo before either. Its got to be a general mobo fault... Right?
 
Checked gpu and ram in old rig. Its working fine! Can't get into bios in the new rig as it either won't post or wneh it does the ami bios code states that its waiting for user graphic interface
 
Check your PSU is working before you point towards the mobo:

When you have eliminated all power problems, memory, graphics and you still can't get into BIOS let alone boot, then it does look like a faulty mobo or CPU. Deciding which will be difficult without another CPU of the same socket type.

When you get to this stage, my advice would be to RMA the mobo. The manufacturer or supplier may charge you if the motherboard is tested and found to be ok. However, it's a small price to pay considering then, you'll know for certain that it's the CPU. If the mobo is faulty, they'll fix/replace it FOC without costing you a penny apart from the P&P. Annoying, but that is your only option unless you buy a cheap low end CPU of the same socket type to test.

That all said, I'm suspecting mobo anyway but check your PSU first.

Good luck
