Problem with M570A

Hi there..

i'm having a problem with my Clevo M570A.. the problem is that because i've installed a program in DOS mode (and now I cant remember witch program is) wich (I GUESS) made the BIOS swap the items in slave and master. Now when I turn on my laptop, it says System BIOS Shadowed and Video BIOS shadowed, then takes lots of time to pass the first screen (the one where I can enter the Bios setup), after a long while it goes to a screen where it makes some checks of yukon PXE and pre-boot execution.. one says exiting pxe rom then stops and says operating system not found.

i´ve tried to solve the problem, by taking the battery, and the small baterry inside the laptop for 1 day so it can clear CMOS, with no results.. I did this because when I enter the BIOs setup and try to manage the master and slave settings they are all blocked.. I've got acess to them, but I cant change them.. and even when i've made a usb to open and install windows again, it opens in the laptop but then doesnt recognize the disc and I cannot install windows :S

Does anyone can give me some help where?!

I need some help over here

 

So you are able to get into the BIOS eventually but unable to change a thing? Have you tried to "restore factory defaults"? Not sure if the option is even there in M570A BIOS.
Another question: have you also tried pressing+holding the power button for 20 sec after removing the laptop and BIOS batteries?

So how far does the machine boot? If you are able to at least boot from DVD-ROM or a USB port, I'd flash the BIOS right away.

 

Well in BIOS I can change all things except the menu related with master and slave devices, I can acess their sub-menus but I cannot change anything in these sub-menus..

By the way the pressing+holding the power button doesnt have any result, as well as in bios setting the option to restore default devices :S

I can boot from a USB but them, as I said nothing is discovered in master or slave, so I cant install a new copy of windows.. I guess something or some program is blocking the acess to them, because of what if explain above, as I enter in BIOS setup..

How do I flash BIOS?! I know i've to make a boot usb, i've alredy done that..

 

I wiil let some pictures so you could see better what i'm talking..

in the BIOS screen.. I guess something is blocking it..





and this is the screen where it stops, because system cant find the hard drive

 

From what you've posted, it looks like your system is trying to boot from the network connection. Since (I'm assuming) that's not what you're trying to do, it's not finding a valid, working network connection from which it can download/run an OS, which is why it's kicking up that error screen you show in your last pic.

Have you been messing around with funky boot CDs or DVDs, maybe using the PXE boot environment?

 

Well, tks for your fast response
I know i've installed something in the windows because of the BIOS, I was trying to update the BIOS.. but them after the install it goes like this screens And it has all the problems I've shown before.. But I dont have in mind what program i've installed :S

 

So, you were trying to do an update to the BIOS? Did you install anything else after that update?

In the BIOS setup, can you disable the option to boot from a network?

 

I'm not quite sure what i've installed, as I said :S but NO when i've made the install in windows mode it asked me for a restart and then is as its shown in the pictures i've taken..

In the boot setup I've got this:


Do you want me to remove the item that says PCI LAN: B02 D00 Yukon PXE from boot order and put it to the excluded boot order?|

 

Well i've exclude the network from boot but it stays the same.. I guess that is not what is blocking the acess to the hard drive

 

I've also removed the disk i've got in the laptop and the acess to the master and slave is still blocked I cant change the values :S anybody help^!?

 

You're not suposed to be able to change them. It is telling you what is plugged in to which physical port on your laptop.

 

After reading the manual, i dont know why but I removed the DVD Drive.. started the pc.. surprise.. the pc starts again, windows included, but only without the DVD DRIVE..

I've tried to put the DVD Drive on its place but when I do this the laptop returns to the previous situation, Doesnt starts and doesnt recognize the Hard Disk.. anyone has a clue for this one?!

 

Have you tried taking the ODD out of the boot order? Or try taking everything except the HDD out (whichever you use IDE/SATA) and then add things back in until it breaks.

 

I'll Try to change the BIOS boot setup so I can see what is wrong in there..
