Oh, yes - you are right. I meant it's nearly impossible to brick the BIOS.

the main partition is destroyed so badly that chkdsk cannot fix it.

chkdsk is fairly useless at fixing partitions though. Not sure of a better tool for actually making the partition useful, although if you have a Linux box available you could see if the ntfs tools there can read anything. Failing that and if you need to get any files from the disk Photorec is quite good

There is always a reset CMOS jumper on the motherboard that you can use when you can't get into the BIOS to reset it.

Having spare parts around to swap in when you suspect a faulty part is always handy. Worst case scenario you can probably borrow something from a friend.

I dont feel quite comfortable tweaking the bios just yet.Because i may screw my pc up ....

No you won't.

Don't be so sure. I just this weekend bricked a PC beyond recovery. Something odd happened and the data on the disk got scrambled so badly that the boot information cannot be repaired and the file system on the main partition is destroyed so badly that chkdsk cannot fix it. And all I did to get in that state was to update the graphics driver... 

That sounds like the hard drive was on its way out already, and the extra disk activity pushed it over the edge.

It is a brand new Samsung SSD that I had just installed. After installing the new graphics driver and just before the failure I had been running Samsung's SSD performance test software. It seems possible that is what actually messed up the disk, but I am mystified as to why.
