Major PC Upgrade Problem - No Picture

Okay, the setup below is what I have installed. After setting it all up initially, it all ran flawlessly. I went through the basics-- installed the chipset and Catalyst drivers, installed some basic programs (firefox), and some monitoring software (CPU-Z). I tried the ATI Control Center's "overdrive" feature, but defaulted immediately afterward since I deemed it not worth it. The computer rebooted fine multiple times after and the last temperature I recall from the control center (before the OC attempt) was 68 C (this is with absolutely nothing done to it). The card is the ASUS EAX1900XT 512.

I planned on OCing my machine, since so many have had luck with the new Conroe chips. I flashed my BIOS up to F6 using @BIOS successfully. Rebooted fine.

I entered BIOS after the reboot with a printout of this guide. I disabled everything as specified in Part 2. I got to the memory adjustments section. I set the multiplier to 2.00 (thus underclocking the memory) and began filling out the first three timings as 5, selected 15 for the last one, but ran down the hall to my friend's apartment to double check if those were correct for my memory. They were, so I went back and continued with the voltages.

I set the memory voltage to +0.1V (since that would make it 1.9, the recommended; I knew the default was 1.8 for this one), and left the other ones untouched while I ran down the hall to try and find out what the "default" voltages were in BIOS for the others, since I didn't know and it didn't say. I knew I had to set them to the voltages specified in the guide, but in BIOS they were all relative and, again, I didn't know the defaults.

After about 10 minutes searching, I just decided to abort, but when I came back to my room, the computer was on, the video card fan was at max speed, and the monitor was in standby-- no picture. I quickly shut it down, and tried restarting-- same thing. I hadn't even gotten to the CPU overclocking settings, and the memory was just reduced to 533 mHz. BIOS makes absolutely no error beeps. The computer seems to boot, despite the lack of picture, because while it's still in BIOS, I can shut down with a single press. After like 20 seconds, I have to hold it down (4-second soft-off), and the HD is being accessed, giving me the impression that Windows is booting.

So I have no picture, my video card fan is maxed, and everything in the case seems to be running fine. POST is telling me nothing, and none of my friends have a PCI-E x16 card for me to swap (which is my first instinct). I need major help on this one. This machine was too expensive for it to not work.

Thanks

try resetting the BIOS; usually you can just flip the switch on the back of your PSU and then flip it back but sometimes it requires you to remove your motherboard battery for a few minutes then put it back in. See if that helps.

 

That was the first thing I tried. I shorted the CLR_CMOS jump and removed the battery; neither worked. Sorry I forgot to mention that.

 

Try cmos, you will have to do it with jumpers or pull the MOBO battery out for a few minutes, flipping the psu switch will do nothing if the MOBO battery is still good, pull power supply plug before removing battery. ed

 

Again, I already tried that. The motherboard gives me a "all good" single short beep and that's it. It's a mystery.

EDIT: just noticed that you sent that right when I replied.

I'm going to try swapping what I can. I think I have a spare PSU lying around somewher-- nevermind... it's not 24-pin... F&@#^*#

 

hmmm only thing that comes to mind now would be a toasted video card but lets not get ahead of ourselves.

try removing/disconnecting (from the mobo and PSU) all your drives, cards except for the bare minimum; video card, one stick of ram. You should be able to get BIOS without your hard drive. if that works, start connecting things one at a time until you find the bad part (if thats even the problem here)

 

The video board is officially fried. I took it to a repair shop to swap some things (because my stuff is so new, none of my friends had stuff for me to swap); they confirmed that the video card is the culprit. PC boots fine with a different card. The box did arrive dented... that might have something to do with it. I'm in the process of RMAing through newegg as I type. Thanks anyway, guys. =)
