Question

Posted

Hy. I can shortly describe my problem with the system as being..wierd. What happened:
1. Yesterday the system freezes and a restart was needed. after that (after bios post) it refused to pass over giving me this error : "[font=verdana, tahoma, helvetica, arial, sans-serif][size=3]clear cmos/resetting your cpu or change frequency for memories" (no overclock on memories/cpu). [/size][/font]
[font=verdana, tahoma, helvetica, arial, sans-serif][size=3]2. After that.. tried to change sata port for my hdd cable (had experienced simmilar behaviour by changing sata cable/port on mobo) and started..with fans(cpu/case pwm) on full rotation :|. Tried an restart and gave me "[b]1[/b]" behaviour back.[/size][/font]
[font=verdana, tahoma, helvetica, arial, sans-serif][size=3]3. Tried to reset bios (got out the battery-moved the jumper from 1-2 to 2-3 and then back..battery back on it's place) and started normally except the fans(cpu/case) which had max. rotation even on windows.. tried an restart and gave me "[b]1[/b]" behaviour back.. [/size][/font]
- tried with different GPU and it's the same.
[font=verdana, tahoma, helvetica, arial, sans-serif][size=3][b]Motherboard[/b] : Asus P5ND2-SLI[/size][/font]
[font=verdana, tahoma, helvetica, arial, sans-serif][size=3][b]CPU[/b] : Pentium D805[/size][/font]

[font=verdana, tahoma, helvetica, arial, sans-serif][size=3]What can be done ? :([/size][/font]
[font=verdana, tahoma, helvetica, arial, sans-serif][size=3]Thanks a lot![/size][/font]

Can you try the PSU in another PC?

Its likely either the PSU or Motherboard.

Sounds like hardware failure with the motherboard.
Try reflashing the bios to an older version then reflashing to the newest version and see if that makes a difference.
I had a problem with an asus board, sound stopped working and ethernet kept playing up, had to send it back to the retailer and they confirmed a problem and sent a replacement which to this day is still working fine.

I can try that psu (arctic cooling fusion 550W) on another pc.. & I will.
How to update it's bios? how long it takes? I'm afraid that if there's a self restart I'll kick the mobo entirely which is out of warranty ;).
Haven't done an update to bios until now.. I have only usb (no floppy)..

You can update using USB, get freedos installed on a usb using uinetbootin and put the flash update files on the USB from asus' site.
Updating the bios takes about 5 minutes.

If I only update to a newer one..what can be wrong? ( I have never updated it).

Any quide related to this procedure? The new bios will overwrite the old one?
If there's no change after all.. the mobo is almost.. dead? :(

Yes you can just update to a newer version.
Look on the asus site for your model and download the newest bios (and extract the files).
Then download uinetbootin and put in a BLANK (or one you don't mind being erased) USB and select freedos and write it to USB.
Then copy the bios files over and reboot, booting from USB, and wait for it to boot up then run the executable file from the bios update zip

- it doesn't have a boot option for usb.. & I must reset bios again (get out battery..) & run it with fans on full rpm.. But the wierd thing is that it worked with actual/standard configuation and bios until now...no hardware changes and so on...

No boot option for USB? Must be, I've got generation older ASUS boards that can boot from USB.

After you inserted the battery back in it's place you needed to go into the BIOS and "Load Failsafe Settings". Did you do that? if not, Just Do It! :D

All the latest boards should have a F key you press to get into BIOS Flash. From there, you just need a file on a flash drive.

I think we can safely assume that a BIOS update isn't going to solve the problem. If the PC worked before, then the BIOS wouldn't magically break everything.

It either has to be the PSU, RAM, or motherboard. Sounds like you can test the PSU pretty easily, and then if you can run MemTest86, that will tell you if any RAM is bad. If that all comes up with nothing, then it's likely that something failed on the motherboard.

Look for leaking capacitors, too, now I thought of it.

PSU wouldn't be changing the fan speeds, neither would bad RAM.
Motherboard BIOS can (in some very rare instances) get corrupted.
But yes leaking capacitors could also explain it. The P5 series of ASUS boards were the first with 'japanese long lasting capacitors' all over the boxes though

Sure, it's possible.
Bad voltages coming from the PSU could cause all sorts of odd behavior.
Same with the RAM if data is getting corrupted.
Both of those things are easy to test, so that's a good place to start.
If the PSU is bad or going bad, it's also possible that a voltage transient blew some components on the motherboard.

this is my guess,but I am pretty damn sure this is your problem.


1.freeze can occur from overheating

2.your fans are on full blast, again from overheating

3. your motherboard told you to check frequencies,because it detected overheating therefore its asking you to lower frequencies

again,this is my guess,but I would take out the cpu, re do the thermal paste,and reseat it properly. try again.

check what temps you are getting in the bios. it should have a temp monitor

So..I'll test de [b]psu[/b] on another system..but I don't think it's the main issue. Haven't understood how to boot from usb.. cause this option is [u]really missing[/u]!

temps. are fine..verified in bios (cpu 31degrees and mobo ~ 38).. I've also considered thermal paste is my worry..cause it haven't been chaged for years (~8yrs) but no worried with temps.

Hello,

This might be a side issue, but given the age of the motherboard, I'm wondering if the CMOS/RTC backup battery needs to be replaced. It's CR-2032 [s]+5VDC[/s] +3VDC Lithium coin cell in a socket on the motherboard.

The battery is used to provide a trickle of current to the CMOS memory, which stores the BIOS settings and keeps the date/time clock going when power is turned off. When the battery drops below the level to keep the CMOS memory charged, the BIOS settings can become corrupted and the clock no longer set to the correct day and time.

Regards,

Aryeh Goretsky

For updating the BIOS on that board you would need to do it by floppy.

If it was the battery being low you can just check the time & date is correct when you set it then power it off unplug it power it on to drain any charge it has and plug it back in and check.

Its likely the motherboard has had it.

Just FYI NO cell battery is 5V, they are 3V.
