Hi,
I have probably built around 8 pc's in my life and all have worked fine (as far as computers go). I'm 17 and decided to build 1 more for college. Specs:
THermaltake Case
AMD Athlon 2700+ 333FSB
ASUS A7N8X Deluxe Mobo
Maxtor ATA 133 80GB HD
2 x 256MB Corsair DDR400 (ultra low latency)
ATI Made Radeon 9700 PRO w/ 128MB Vid
Your basic cdrom/ cdrw crap and floppy
56k modem
Ok I put it all together like normal and turned it on. BUZZZ all the fans came on and them nothing else happened. I can open and close cd trays, green led on mobo is on. However absolutely nothing comes on screen. No beeps or nething. Well then i started with your basic troubleshooting. I tested on another pc the ram, cpu, vid, hd, and power supply and everything worked fine. Unfortunatly there's no good way to test a mobo w/ another system. I have no idea of what to do. ASUS also has that special vocal warning thing but no noise (not even beeps) are produced when it comes on. Please if you have any suggestions reply to this. Thanks
Hi again,
Ok look at the what light? I have no idea what your talking about...Anyway more probs, ok there's 4 pcs in my house all of which I built. Now only 1 works. 3 worked fine last week and the new one I built this week never worked. I would be thinking power surge or spike but they weren't all plugged in at one time. Plus I have surge protectors. Anyway they all do the same, when I turn them on all the fans (including ones in pci cards and cpu's) come on and then nothing comes on the monitor, and I know the monitor works. However one with a biostar mobo bleeps twice when i turn it on, anyone know what that means? Well any idea please drop a line. Thanks
Are they long sustained beeps or short? I believe if they were short thats some kind of damage to cpu but im not really sure. If a bunch of your comps went out Id be looking into UPS's or something similar

A7N8X - Theres a green LED located between a couple of PCI slots that illuminates as soon as theres power in the PSU - regardless of if the machines running or not. My guess is that you're probably getting power to the board if your front power button is working so it's probably on.
In this case I'd get your mains Power looked at as it may not be giving enough juice. This this could explain why none of your pC's will power up. If you're LED is illuminated I'd try the following before condemning the board:-
Regarding my first comment - check to make sure nothing silly has happened like the brightness of all your monitors has been turned down - dumb as it seems it has been known to happen!!!
Maybe the boards locked up from a wrong frequency initialisation from which it can't recover so give it a full reset - unplug the mains lead for a minute, revove the battery for a few minutes more then toggle the clear CMOS jumper.
Grab a multimeter and test VDC of your motherboards ATX Connector by probing the backs of the plug pins when the boards powered on and off.
If possible try a PSU from another High end system that will be sure to supply the juice needed - It's often that a good quality PSU is sacrificed for a better component. A quick judge of a decent PSU is the weight of it literally, they're heavy.
Clean the connectors or your RAM and Cards using a soft pencil erasor, failing which test them in another rig.
One day I'll look back at my current rig the way I do my old ZX Spectrum.......Would have been interesting to say the least if Sir Clive had Bill G's business skills
Thanx for the ideas however I have some new news. I've fixed 2 of the pcs. Yes those were power supplies/ mobo probs (voltage). However for my new pc I tried the processor in another nforce 2 pc and it didn't work and I also tried there stuff in my motherboard. Ironically I got both my processor and mobo from the same place (computer brain) and neither work, I'm going to get a return on each and see if that helps.
Ok, now I've gotten it to start up a bit, however everything seems fine and then the WinXP loading screen comes up and it immediately reboots, it does this in a continuous circle then on. I have tried different freqencies and different voltages for the RAM with no success.
