i built my pc about a week ago and ive only had one problem. every time when i boot my pc up in the morning, i have to turn it on atleast 3 times before the bios comes up. it only does this like after i leave it off for several hours and ive updated every possible driver and bios. im suspecting its the video card because the monitor works fine, but i might be wrong. please help, it does this exact same thing every time i try to turn it. heres my system...

amd 4200x2 with zalman 9500
foxconn C51XEM2AA
corsair xms ddr2 800
ati x1900xtx
soundblaster audigy2 ZS
WD 160gb 7200 sata2
silverstone ST56ZF 560w
lian-li pc-v1000
 
This sounds more like a mainboard issue than a video issue.

But just to make sure of it. When you turn on your computer, do you get the POST beep and no display?? Or do you get no beep and no display??
 
Same thing happened to me with system in my sig. I could turn my computer off for an hour and turn it back on just fine but if I left it off for a couple hours and turned it on I got nothing so I would have to turn it off then back on then off then back on and then it would finally boot. It doesn't do it anymore and I dont know what I changed to fix it or when I changed the setting to fix it. I think it was something todo with wake on lan or removing it from the boot device list.

When I say bootup list I mean the crap were you select boot order
1st: cdrom
2nd: harddrive
3rd: Network device
 
well it does the exact thing everytime, heres the sequence.
1st time: comp runs, monitor picks up no signal and no beep
2nd time: comp runs, sometimes the bios actually post but no signal on monitor
3rd time: comp runs, basically same as second time only i actually have a display but it lasts for like 2 minutes and then goes blank.
4th time: works perfectly fine

i have seen sum1 with a similar problem and sum1 told him to plug his AUX power connector and he says it runs fine now. just found this thread like an hour ago and i checked and found that i too dont have mine plugged in. so maybe i have just solved my problem.

is that the list you currently have and works fine?
 
oh i see. i dont know if mine problem has to do with the order of my boot devices cuz im pretty i set them correctly, but i could be wrong. well the only real way to test this out is tomorrow morning, or like overnight.
 
Next time it happens wait a few minutes each time it doesnt start. I just remembered every now and then if I let it sit sometimes it would show some crap about dhcp.

might just do that. cuz usually i just boot it up again like 15 seconds after the first try.
 
nope, still wont boot up correctly on the first try. left it running for 4 minutes and nothing came up. it did run corectly the second time though so i guess thats progress.... im not sure what to do now. :confused:
 
Im sure its a setting within the bios. Try disabling everything your not using. If your not using wake on lan wake on keyboard wake on mouse make sure there disabled. If your not using firewire\parallel port\other crap disable them if you have them.


Next time it happens hit escape then wait a minute to see if it boots. Make sure nvidia boot agent is disabled.
 
nope, changed some bios settings, i changed the order of my boot devices to cd-rom as first, harddrive second, and removeable third. set my initial start up display device from pci slot to pci-ex slot. but i notice i had 2 lan settings enabled so i might disable those and see what happens.
 
This is really sounding like a power problem. Could be that your PSU is sending "Power Good" too soon, or it's voltage aren't stable until it's been running for a few minutes.

OR

your motherboard's power regulation system is flaking out.
 
that doesnt sound too good. ill check the warranties on my mobo and psu see if maybe getting a replacement it will do anything. but im not up to that point yet, i still want to see i can fix this without replacing anything.

do you know if there is a way to really know if thats the problem, and if it is then do you know a way to fix it or should i just get a replacement psu or replacement motherboard?

Check the PSU voltages with a multimeter while your turning on your system.

Use a hardware monitoring program to see if the voltages are fluctuating.

well i do have monitoring programs to check voltages so ill do that when i get home from work. my dad has a multimeter somewhere in the garage so he will help me with that. i actually do remember seeing something with my voltages, cuz i use ntune monitoring program and it checks your voltages, temps, etc. and i remember seeing some voltages changing frequently. didnt know if that was a bad thing at the time, but i never paid much attention to them.
 
ok my current voltages are listed here.

cpu...1.36v
memory...1.89v
+3.3v...3.28v
+3.3vdual...3.28v
+5v...5.12v
nforce mcp...1.49v
nforce spp...1.2v
HTcpu<->nforce spp...1.2v
+vbat...3.06v

(note), these were taken from the bios. the monitor program on windows picked up similar voltages but some of these werent listed. on the bios, some of them changed by like 0.02 volts, not much else. on the monitor program they did not change at all. hope this means anything.

You're missing the 12v readings.

But the biggest that needs to be seen is that the voltages are where they need to be within a short period of pushing the power button. For that you'll need a multimer. Or you can get a known good (or new) PSU and see if it fixes the problem.

yea i can just get a replacement like in a week, but one question how can i use a multimeter for this situation? where do i put the two probe things to measure the voltage?
 
ok, i forgot i had speedfan and it does have my +12v readings. it measured 8.5v. i dont know much but shouldnt 12v be pretty close to 12v? and then it said my vcore was at 1.24v and my AVcc at 3.3v. i dont know what the other two mean but the +12v one scares me allittle, and maybe thats the root of my problem. although speedfan didnt get my temperatures correct at all, so im not sure if these are correct either.

Yeah that 12v is horribly low. shouldn't be less than 11.4v. The AVcc is Aux voltage, and is probably right. 1.24v is voltage being fed to the CPU core. and it's value is dependant on the 12v line, and may also be low.
 
12V rails are the ones that supply power to your gfx card.

even with only 8.5v not under load your X1900 might be able to function.

easy way to test it is put your card under load, but then i dont know just how damaging power depravation can be...

but yeah if you start getting effed colors/artifacts/ .001FPS then yeah your card ant gettin the juice, and its time to start complaining to the company you bought the psu from.

you dont have any other computer you can just swap the psu out of huh?

12v also drives HDD motors, and CPU voltage is derived from the 12v lines now as well.

There's a chance that those readings are wrong those. What I would do is get my DMM (set to Vdc) and put the +(usually Red) probe to a Yellow wire on the ATX 20/24 pin connector and the --(usually black) probe to a black wire in the same connector. With the PC on and preferrably under load like dual Prime 95 and WMP playing a video compare your reading to the ones you got from speedfan.
 
i luv google. searched (my motherboard) + voltage problem and found that this guy seems to have the same problem. funny how he has the same cpu, mobo, and type of memory as me yet he gets the exact same voltage from speedfan and pc wizard but his psu is completely different.
 
ok i dont know if this would work, but if i bump up the fan rpms on my video card or if i do a video stress test, would that cause the voltage to go up? ill do it anyway just to see if it does because ive never looked at the voltages much, but just wanted to know.

+12v lines should always be +11.4v-12.6v. Do the test I mentioned aboved to make sure your motherboard isn't reading them wrong.
 
ok well i dont have time to do that tonite so ill try that in the next couple days to see what it brings up. at this point i dont care what the problem is, i just want to find it and replace whatever is defective...
 
i have a similar problem. when i cold boot i get nothing. the screen goes into standby. only when i hit the switch on the rear of my psu (turning it off) & then hitting the switch again (turning it on) will my computer boot. it's a real p.i.t.a. but i deal with it because i could not find a fix. your help would be greatly appreciated. i did check my rails recently and they are all within spec.

well your problem doesnt sound like mine, how long have you had that pc? did you build it yourself? has it been doing this since you built it?

i have had this setup about 6 months.

i did build it myself. on this latest upgrade i upgraded the mobo and video card.

yes it has done this since i upgraded the parts.

thanks again.

well i guess that reduces all the other possible problems and leaves you with your motherboard and video card. or maybe its a compatibility issue. do some troubleshooting and remove certain stuff and see if it keeps doing it.

edit: basically just look through this thread and see what people have been telling me what to do, but so far I havent fixed it yet, so hopefully you have better luck.
 
ok to use the multi meter, should i unplugg my gfx card and measure the volts on that connector, or just any connector. and if i measure the volts on the pci-ex connector, im gonna assume its the black probe with the black wire and the red probe with the yellow wire, right? because i dont see how else you could do it.
 
I read a thread on here yesterday that was talking about newer motherboards not turning on high efficiency PSU's because of how th BIOS staggers the power up of high draw components. Maybe this is what your problem is.

Anway to answer your question. use the motherboards ATX connectors. black probe in black wire, and red probe in yellow wire. You don't have to unplug it, but put the probes into the backside of the plug where the wires go in. Just make sure your making contact with the pin inside.
 
hmm, can you give me a link to this thread because that could be useful.

so when i get the measurements, should i be looking for anything closest to 12v? or exact?
