just built a new gaming rig P5N-D ASUS mobo, Intel Q9550 cpu, EVGA 9800GT graphics SLI mode, Corsair TX750 psu, WD Caviar Black HD 1TB, OCZ SLI 800MHz 4x2048MB, Corsair H50 cpu cooler, CM Scout Case, will install Windows7 Pro when i get it up and running. Now my problem. when i enter setup (and i have to enter at power on) i only get 1 or 2 keystrokes then i freeze. i have the latest bios, used both jumper settings for the keyboard, reset the cmos, i can`t even set the time, after 1 keystroke i can`t navigate anymore with the keyboard. Any suggestions?
If you are using a USB keyboard, I would try using a old PS/2 keyboard.
Try testing the memory with MEMTEST 86 or using different memory.
Try testing the power supply or using a different power supply.
Try a different processor if you have one.
Pulled all memory but 1POST screen says memory`s ok but system froze entering setup. also northbridge seems mighty hot.have 3 different keyboards same problem with all of them. All of my fans lights dvd player and graphics card works. i may have another processor i`ll try that as a later resort, what about the northbridge running so hot what could that be?
thx, wen`t to ComputerBay they custom build and repair. Bought 1 stick he uses on the P5N-D mobos when he builds them. that didn`t work i still have the same problem. I think i`m gonna take it in, it`s $30 to test everything but a 1 week wait. So ram isn`t the issue since ive tried 5 compatable sticks at least. thx delluser1 for your help
Should have been more clear on that, you would be removing the NB heatsink.
This needs to be done with the board out of the case.
I use a pair of needle nose pliers to pinch the pins ( from the back side of the board ) and remove them.
yh delluser1 i figured it had to be out of the board and needle nose would need to be used, just seemed to me pinching them would damage them and wondered if there was a better way. here`s an update i put a hard drive in from another pc i have got all the wat to where the microsoft bar rolls across the screen then the bright blue screen flashed on the screen couldn`t tell what it said but from past experience i think it was warning for a memory problem so i need to find out what to set to 5-4-4 and 2.1v to see if that helps
thx again delluser1, finally was able to contact ASUS tech support and was told it`s probably the memory controller and the board needs to be serviced. thx again delusser1 for your support and all who contributed
