Asus P4C800 Rev 2.00
Antec TruePower 430W
Corsair TWINX1024RE-3200LL 2x512Mb
Asus GeForce 4 Ti4200
Seagate Barracuda 160Gb 7200rpm
Lian Li PC60 case
The problem is this.. when I when I start the computer, all hardware and fans start up, but I get no signal to the monitor. No post beeps either.
The first thing I tried was changing graphics card. I tried with two others I know work, but no progress.
I tried with either of the ram modules, and with no ram modules at all, but no progress.
I tested with a P4 2.2Ghz 533FSB cpu, but still no progress.
I resetted CMOS using the jumpers, and finally I had some progress. Now the computer started beeping when I started it. 1 long, 2 short beeps. But still no signal to monitor.
I know there is nothing wrong with the PSU, I've used it for a month in my older computer.
I assumed that the motherboard was faulty, so I returned it and got a new one. Still same problem...
At that point I handed the computer in to a computer service-place to have them look at it. At first they seemed clueless as well, but then they found out that the ram was faulty. Both of the modules.
Strange enough, when I got the computer back from them, it was no longer beeping. But all else was the same.
So I returned the ram, and got new ram yesterday. Last night I put it in, and guess what.. same problem. But no beeps. It doesn't beep without ram either. And no signal to monitor.
I seriously need help with this computer. I've been trying for three months now.
If someone could help me solve this I would be eternally grateful.
It sounds like your RAM settings are what's locking you out. You need to hold down the delete key to get into the BIOS and then set the following. Its the most likely cause for the symptoms your describing.
Here is what I would set in the BIOS:
Advanced Tab --> Chipset:
Configure DRAM Timing by SPD. . . . . .[Disabled]
DRAM CAS# Latency . . . . . . . .2
DRAM RAS# Precharge . . . . . . 3
DRAM RAS# to CAS# Delay. . . 2
DRAM Precharge Delay. . . . . . .6
DRAM Burst Length. . . . . . . . . 8
Performance Acceleration Mode. . . . . .[Auto]
Put everything else to defaults except for your Graphics Aperture Size, set this to the max Value of your Video Card (i.e. 128 or 256 etc.)
Advanced Tab --> JumperFree:
AI Overclock. . . . . . .. . . . . . . . . . .[Manual]
CPU External Frequency (Mhz). . . [200]
DRAM Frequency. . . . . . . . . . . . . . [400]
AGP/PCI Frequency (Mhz). . . . . . . [66.66/33.33] (This is critical to set, so that you lock down the Frequency)
CPU VCore Voltage. . . . . . . . . . . . [1.6]
DDR Reference Voltage. . . . . . . . . [2.85V]
AGP VDDQ Voltage. . . . . . . . . . . . .[1.7] (For a 9500 or greater I'd use either 1.6 or 1.7)
Performance Mode. . . . . . . . . . . . .[Auto] (to start with I'd leave this to Auto and once you determine that your stable, then change it to see if it works for you.)
You should also disable USB Legacy support and only use PS/2 mouse and a non USB keyboard to start with. Once you get everything up and running and test your stability with MemTest86 and Prime95, then you can start tweaking these settings. Remember, if your going to overclock you want to start by keeping your memory timings loose and push the FSB as high as it will go and remain stable, then and only then should you start tightening your memory timings.
Let us know if this still won't post for you and we'll try to determine what else you might be able to do to get this working. There are a bunch of people here that run these same sticks of RAM so it's not a specific problem with this RAM/MB combo.
Hope this helps.
