After a sudden burned AGP port on my last mobo (!), I went out and bought the following:
Asus A8N-SLI Premium
Silverstone 650W SLI-Ready, Quad 12v rail Power Supply
XFX Geforce 7800 GTX XXX edition, PCI-Express
Coolermaster Wavemaster Case
Arctic Silver 5 Thermal Compound
I kept some of my previously working components:
AMD Athlon64 3500+ (do not know the revision)
2 x 1GB Kingston ValueRAM PC3200
Sound Blaster Audigy Platinum eX
Gamepads, USB devices, etc.
I had some pretty noobish mistakes while putting it all together (I've built at least 15 PCs). First, one of the CPU pins bent, so I had to grab a metal file and try to straighten it up. According to me I did it correctly - the pin did not come out and it appeared almost straight.
Then, I installed the PCI-e card and apparently I did not seat it correctly. It appeared fully seated but the very end of the card (right next to the metal slot cover with the DVI connectors) was squashing one of those small black cyllinders (I think they are called capacitors). I did not realize this until later.
I hooked everything up and turned on the power supply. The motherboard has a small led that lighted green, which is great according to the manual. However, when I press the power button, everything appears to be "running" (all fans spin) but I get no video from the card. I get no beeps either. I thought the speaker connector was upside down and changed it to no avail.
I realized the problem with the card, so I carefully straightened the capacitor so the card would not squish it and reseated the card. Nothing. I removed the RAM in hopes that the mobo would beep. Nope.
This motherboard does not have jumpers so I think I cannot select single or dual video with a jumper (thinking perhaps it is preconfigured for SLI - although unlikely in my opinion). I am placing the PCI-e card on the blue slot which is the one you should use in a single display setup.
The mobo also has a system called AI POST Reporter, that streams prerecorded speech sounds through the onboard audio port when posting. However, I hooked some headphones and turned the thing on and I hear nothing.
I can imagine several possible causes:
a) I burned the PCI-e port when the card was squishing the capacitor. I don't think so, I would think this is REALLY REALLY unlikely to happen.
b) The processor was damaged / the pin fell down / the pin is not making contact. Could be, I hope not. In my opinion, not very likely. I will check tonight if the processor still has all pins and everything.
c) There is something I have not hooked. HIGHLY unlikely. There is a connector called EZPlug on the motherboard that is a molex connector, but according to the manual, you should only connect a cable from the PSU to this connector if you are using an SLI setup (obviously the 7800gtx has its own power connector). Other than that I don't know what else could be unhooked.
d) I checked the ASUS webpage for troubleshooting. I found this page.
I haven't done any of the steps on that page (it was VERY late yesterday ) but I would think the only probable one is the Supported CPU List. I don't think I would have to "reset the PSU" since everything is brand new. Also, clearing the CMOS makes no sense to me for the same reason. I will try them though.
I found something odd in the Supported CPU List (see page above). There are five 3500+ processors listed. Of those, there is one that requires the 1009 BIOS, another that requires 1006 BIOS and all others require 1004 BIOS. I do not know what version of the BIOS I have, would I be sooo unlucky that I have a certain processor version and that my motherboard is not flashed to the latest BIOS?
I don't know what else to do. I don't think the mobo is shorting, the case is really good and I placed all the risers and everything. I could try with a different processor/ram/video card but guess what, I don't have any of those to spare
I really want to put all this together soon and I would like to try everything before having to return the mobo, card or buy a new processor (I hope not! ).
Any suggestions are greatly appreciated. Thanks in advance!
