I had recently post a thread couple of days ago but i wasnt sure i get satisfying reply.So here i am asking again if anyone of you have expertised advice for me.

4 nights ago i had completely built the system for my friend.

Asus P5k P35 Mobo
2G PC5300 667ghz Geil DDR2
320 Seagate Sata Drive
2ghz Core 2 CPU
Asus EN8600GT Graphis Card
Antec Earthwatts 500 PSU

Anyway, have flashed the BIOS setup with the latest updates cause i thought it would fixed the problem but the same thing happened.

Now heres the problem:

When i hit the power switch the monitor stay blank with yellow signal and no power signal from the USB keyboard and USB mouse.
So, i have to hit reset switch to get the Windows loading and everything works fine.I suspected this may not a big issue but i find it annoying and worried by keep hitting the reset switch could damage the hard drive.

Hopefully there is a simple solution for this that i could hear from you guys and it would be greatly appreaciated.

God Bless!!

I don't think you will really damage the new HD as this isn't really a huge issue with modern day drives, however I can see the annoyance.
I would say try loading factory BIOS settings and see if that does anything for you... If it works, progressively change your settings again until you have what you want.

The only thing ive changed from the bios setting was:

1.boot priority into CD drive since i didnt have any floppy in the system.
2.i disabled the asus boot logo which i probably dont need it anyway.

The rest of the settings mostly we're in "auto" so i didnt bother changing it.

Just curious,do you think the Windows(XP) has something to do with it as well?

I'm having boot problems that sound similar. When I press the power button it powers up, all fans are go, harddisks seem to be spinning, LEDs on the front of the case, but no signal to the monitor. Monitor works fine with other box.
So I soft reset. No difference, hard shutdown and then power up, now it starts up....
Never works on the first try, but will finally power up if I keep reseting, turning off power, reseting again etc.. Seems fairly random when it actually works. I have yet to enter the BIOS. I updated the other hardware drivers.
Any suggestions?

I am experiencing exactly the same symtoms as you user2012, have you had any luck resolving the issue?

I have just updated to the latest BIOS and dissabled Q-Fan Control as someone suggested it might help, too soon to say whether its fixed the problem yet.

Hope someone out there has some suggestions!

i had problems with my bios resently.. so i read some stuff about it...

after the bios update... did you changed the settings to default on the first boot after the update?
if not- it probably the coz to this problems.... do so. it must be done.
also, try also clearing the CMOS.

if you did the update from Windows, the worst bios update method...
re-update it or reflash it completly from a usb drive/cd/1.44mb

for more details go to biosman.com
it explains better than me every little detail...

update us so we can help & learn...

I have found the 0404 BIOS to be very good on the P5K Deluxe. Still, you shouldn't be having this problem with any BIOS. Reset the CMOS BIOS by
1. unplug PC from the wall, hit power switch to discharge residual elec.
2. remove the battery
3. move the clrtc jumper from pins 1&2 to 2&3, let it sit for a few seconds and then put the jumper back on pins 1&2.
4. replace the battery
5. plug the PC back into the wall, reboot, enter BIOS and set boot order.

You can try disabling Legacy USB as well. Don't use Q-Fan.

If that doesn't help, try a barebones setup as per the below guide:

This is a little guide I made up for doing a barebones setup. It is a great troubleshooting tool that all of us need to use at one time or another. If you can see any changes that will improve this guide, or the procedure, then please post them as this is a work in progress.

BAREBONES SETUP

You are going to have to do a barebones setup and test each component. This will read a lot harder than it actually is. The initial procedure takes only around 10-15 minutes. The follow on troubleshooting may take a lot longer though. Also, please do not skip steps. Do everything in order and as listed or your troubleshooting will be flawed.

Caution: Please remember that turning a PC off does not mean there is no power going through it. Modern systems maintain a trickle of power to keep the standby functions running. You either have to turn off the switch on the Power Supply Unit (PSU) itself or unplug the system from the wall. Unplugging is best. If the green LED on the mobo is lighted you have power to the board. Make sure it is out before proceeding. Also, be aware of static. Make sure you wear an ESD strap or discharge yourself on a steel part of the case before touching anything inside.

First, unplug the PC from the wall and then push the power switch for a second to discharge any "leftover" electricity and then open up the case. Disconnect all the drives (floppy, CDROM, DVD etc.)from the motherboard (mobo) and also disconnect your Hard Drive(s) from the mobo. Do not leave the hard drives connected, the system will boot into BIOS just fine with no hard drive attached. Unplug the power from all those drives you disconnected from the mobo and remember to disconnect the front panel firewire and/or USB ports. If you have a PS2 keybard and mouse, use them instead of the USB models.

Next, remove all the RAM, except for one stick, from the mobo. Some mobos are very picky about where the RAM needs to be placed so make sure the one stick of RAM is in the correct slot as per your manual. On the A8N SLI Deluxe this slot is the third one (B1) as you move away from the CPU.

If you're SLI then remove the second video card. Remember to set the SLI Selector Card to single. Unplug the EZ plug molex from the board.

Now you are stripped down to a barebones system. The PSU, the mobo itself, 1 stick of RAM, the CPU/HSF and one video card. Reset your CMOS/BIOS while the system is stripped down, unplugged and open. You do this by removing the battery and then moving the jumper near the battery around. On the A8N SLI Deluxe there is a set of three pins, with two covered by a jumper, right next to the battery. After removing the battery, you move the jumper from pins 1&2 to pins 2&3 and let it set for a few seconds, then reset the jumper back to pins 1&2 and replace the battery. BIOS will be back to default settings after doing this.

Now, check that everything is seated correctly, RAM, video card and its power plug if applicable and the 3 pin CPU HSF power plug. Check that both 4 pin (P4 Power)and 24 pin power is connected and secure. Now plug the PSU back into the wall and turn it on. The green LED on the mobo should be lighted. If the LED is lighted then turn the PC on. Hopefully she boots right back into BIOS.

If you get back into BIOS you can start troubleshooting by turning the PC off, unplugging it and reconnecting peripherals one at a time. The idea here is to connect and reboot, until something hangs your system up. This, presumably, is the bad piece of gear. Start with the optical drive and floppy drive, then the hard drive with the OS on it and finally the second video card if applicable.

If you cant get into BIOS then you know it is either the PSU, the RAM, the CPU, the mobo itself or the video card. Change out each of these until you get into BIOS. I would start at the PSU as it is usually the guilty party in a situation like this and is also easy to change in and out (you are down to just 2 plugs, now, remember). Next up would be the video card and/or RAM and if still no luck then things get hard as you now have to consider either the CPU or the mobo.

Good luck and happy hunting.

Sounds like you don't have your reset and power connections plugged in right. Try swithcing them around or reading your instructions better.

Thanks for your ideas and suggestions guys.

I am currently in the throws of trying out the Barebones setup.

A couple of comments on the guide fist, no criticism, it made great sense and had to be the best way forward for me to try and isolate what was wrong, thanks again:

1) Might be worth mentioning to remove speakers, network cable etc just leaving the graphics card attached, in case any of these are causing the problem.

2) I would suggest that when you’re still not getting into BIOS with the barebone setup, as was the case for me, the next quickest thing to check is the RAM, especially if like me you have just taken out one stick of RAM, so I swapped the RAM sticks round and tried again (easier than swapping the power supply and possibly a more likely cause of the problem).

3) One thing I wasn’t sure about was when the best time to turn the machine off was, if you are running the barebone setup with no floppy, HD or Optical drive, you successfully enter bios, do you turn off before exiting bios, or let it exit BIOS and die as there is no operating system and then turn off or doesn’t it matter?

Any way back to my situation, after several attempts with the barebone setup I eventually saw my problem again, unfortunately my problem seems to be intermittent so you have to repeat everything several times before it displays the problem again or indeed whether you can be sure it has really been fixed.

This is my current situation, I have swapped the RAM sticks round in the barebone setup and have tried to power on several times, which so far, have all been successful but I am still not confident that it really is the RAM that is the issue. I suppose time will tell but is there some way of checking the memory which might speed this process up?

I have checked the case switching connections to the motherboard but this doesn’t rule out the possibility that the case switching is not at fault but probably one of the least likely causes.

Their could I suppose be something wrong with the BIOS after I flashed it but I haven’t ventured back down that path yet, is it really worth it?

A reminder for anyone reading this what my problem was so they don’t have to go trawling through the previous posts:

When I press the power button it powers up, all fans are go, as is the power on LED on the front of the case, but there is no signal to the monitor and harddisks are not spinning. Monitor and graphics card work fine with other box have and have updated to latest BIOS 0401 and reset the CMOS BIOS as part of the barebone setup.
So I soft reset. No difference, hard shutdown and then power up, now it starts up....
Never works on the first try, but will finally power up if I keep reseting, turning off power, reseting again etc. Seems fairly random when it actually works.

My System is:

Asus P5K-VM
Intel Q6600 (Zalman CNPS8700-LED)
Corsair XMS2 8500 Dominator
Enermax 500W modular ELT500AWT
Silverstone SG01S
MS Win Vista Home Premium
NO Overclock all on AUTO

This seems to be a theme with the P5K series - mine behaves pretty much the same - tho when everything powers up and spins and no boot, I do notice my fans kick up several notches....I thought maybe it was a power issue, but the Ultra X3 I just put in has no effect....anyone browsed ASUS forums for this issue?

I have had this same recurring problem with my Asus P5K Deluxe mobo. Usually a quick fix is to clear the bios back to default settings. Now I dont know what triggers the random non-video post; however when you have the chance, enter bios and change the setting: "vga post on s3 resume" (or something like that) to enabled. This should prevent no video post from occurring again in the future. It has for me.

I have had the same boot problem with no post screen on my P5K m/b and just found the answer on the Asus forums.

It seems that a Lan driver update offered by Microsoft Updates causes this problem. Fortunately there is a simple fix, just flip the switch to off on your PSU and leave unpluged for a while (30 minutes) and then replug &, turn the PSU switch to on and boot should work as expected. They also recommend you return the lan driver to the original.

Since this problem is so pervasive with the P5K I thought it worth posting here.

Yeah I had the same exact problem with my Asus P5k. I have been doing this unplug the PSU trick for a while now and it definitely works. So that means no other BIOS upgrade can fix this black screen bootup issue? BTW, the PSU needs to be unplugged for a while until the motherboard's built-in LED goes off. Then switch the PSU power to on again.

Update: Unfortunately, this fix did work for a couple of days, but the problem did re-occur randomly for me. It's obviously not the driver issue for me(although that was an incorrect driver), but I still use the power down fix I mentioned above when I can't boot. I think this must be a bios issue because I get a message sometimes during boot saying "overclocking failed" but I'm not overclocking. I even tried setting the memory timings & voltage manually to stock hoping that might bypass the issue of the bios automatically detecting and setting the timings, but this didn't stop the random boot/post problems.
