Can't boot

[prog_tom]

The pc can't boot. I press boot button don't boot, no power. but the mainboard LED is green.


I tried to use magnetic screwdriver to manually boot the pc by pointing it on the PWRSWTC pin on the mainboard panel. Doesn't work.

Someone pls help.

Take out and re insert the battery. Maybe that will work...

"boot button"? lol

Anyway, you say there is no power, but then you say a green light is on. So which is it?

Does the mother board have any lights on and does it beep any? If so look up the beeps in the motherboard's manual.

and why the hell would you use a magnetic screw driver for inside of the PC!? *** is the PWRSWTC pin? To boot, you shouldn't have to ever connect pins unless your mother board is seriously ****ed AND it's real old.

The BIOS would get set back to default each time if it had no battery and it woudln't keep time, but it should boot perfectly fine without a battery (I've had 2 of my friends who had to do it a few times before)

It happened to me once that I closed my PC and then when I pushed the power button it wouldn't do anything! A friend of mine suggested to take out the battery and re insert it and after that it worked! I have no idea why but I just figured I would suggest it...

LOL :D

OK, when you switch it on, do you at least hear the whirring of the hard drive? Try "booting your boot button" :D and leaving it on for a couple hours.

THAT has worked for me.

He didn't say the CMOS battery was the problem! He meant remove it, just in-case he had a BIOS problem/virus etc...

Noob!

You might need to buy a "boot quicker" button from http://www.mypcisfubar.com

:p

Check the PSU...

BIOS virus....


........

and I'm the noob?

HAHAHAHAHA

The only reason the CMOS battery would need to be taken out is if the battery WAS the problem. You can clear the CMOS without removing it. If you remove it, sometimes the CMOS won't clear for hours, even days.

Also, if your BIOS had a "virus", the computer wouldn't be working at all. The only way to modify the BIOS is to flash the chip, and I could guarentee you the BIOS would be ****ed. Clearing the CMOS would NOT bring the BIOS back after a flash. The CMOS just holds the settings for the BIOS. This is why companies warn warn and warn about flasing your BIOS because once you **** up a flash, you gotta get a new mother board or atleast replace the BIOS unless you own a flashing piece of hardware, which I highly doubt.

*Paul senses argument coming on.... *

The average CMOS discharge time is 3hrs, which makes sure all capacitors/resistors etc have been flushed of any current. When the CMOS battery is removed, it litterally 'breaks' the connection between motherboard and supply, therefore killing the CMOS. Remember to unplug the power cable!!!!

I'm a little confused with your "bios virus" comment though! His computer ISN'T working at all, so it's quite possible it's a BIOS virus (it's doubtful... but possible!).

Oh... and what the bloody hell are you on about with the...

"there's only one way to modify a BIOS" !!??!!

Have you ever modified your CAS latency settings for your memory? That would stop your system booting, and no flashing was involved there! You would need to kill the CMOS, by either removing battery for a while, or easier method... swap the jumper (if your board isn't soft-set).

I really hope you are kidding! Remind me never to buy a PC from you!:D

If you FUBAR your BIOS, then you would use the boot block feature to recover... You should not need to buy another motherboard for christ sake! There are many other ways to recover from a flash problem, like live-swap... but it can be dangerous for novices/kasracers! :p

I don't think much of your guarantee m8, cause half that post was complete crap!

I need another drink!

There was a nasty virus some time ago called Win95/CIH, which only infects Win95/98 systems, but if your BIOS had write-disabled -- enabled (lol) then you'll be safe.

The infection details of that virus look worrying similar to yours! :eek:

BIOS viruses are very rare, as writing one that is capable of crashing EVERY type of CMOS and every setup of system would be incredibly difficult, else impossible!

Always check the basic's first!!! I can't stress this enough! A friend (who will probably read this message :D ) was trying to fix a PC back when we were at college. After nearly 30mins of fiddling, faffing... he said it was completely wrecked beyond repair! 4 seconds it took me to turn up the contrast on the monitor!!! You needed to be there... but it was so funny! :p :wave:

[scostell]

I bet it's the power supply. I had the exact same problem a few months back. The mother board light would go on and seeing that I thought the power supply was ok. But after trying everything I could think of I figured "why the he'll not" so i changed the power supply and everything worked after that.

BIOS doesn't have room to contain a virus and the only way the BIOS can be modified is through a flash.

Dude, that isn't a BIOS virus. That's just some retarded virus for Windows. If it was a BIOS virus, it would modify the BIOS and work reguardless of any OS, but be dependant on the BIOS version and/or manufacturer.

What you're refering to is just some retarded script kiddy who figured out how to change a setting in the CMOS from within Windows.

A BIOS virus would be a program that is flashed onto the BIOS, and I've never even seen one of those.

No, remind me to never ask you for PC advice. Once you **** up the BIOS, it's time for RMA.

Send me your mother board and let me flash it. I'd love to see you recover it without the use of an external piece of hardware. Oh and boot-block isn't on all mother boards. The special features of boot-block is propritary to Intel. So that wouldn't work too good.

**** it, I'm working on stuff today. I surrender, I don't feel like arguing or anything.

[VisionIT]

Hmm... there's a strange correlation emerging in your posts! Anything you don't understand you class as "retarded".... why is this? I wonder how many times that word has been used, and in what context!

If you'de done your research before posting that message, you'de already know it is a real virus, and was a real threat too! The reason it's only restricted to Win95/98 systems, is because the vulnerability is only situated in those OS's! I know any BIOS virus that's directly called by the user would infect any system, regardless of OS... but this is done live; over the net!

I'm also confused about this "BIOS doesn't have any room for a virus" ??!!?? Are you saying BIOS viruses don't/can't exist? If so, why are they called BIOS viruses?

It doesn't really matter what cache the BIOS chip has allocated... the memory isn't addressable in any way... :confused:

Heehee, I bet he responds... :wave:

[JimCarney6]

don'ty know if someone told you this yet on this thread, but take the battery out, and let that light power down. give it some time and plug it back in. i have had the same thing happen, and it needed time to let the energy disipate i suppose. then it fired back up

it's an Asus A7V8x motherboard, so it shouldn't be that old
