Hardware troubles

Only 1 man can be an expert...its you!

the motherboard is probably close to dead

Heh, what do you know - I switch to the second BIOS - doesn't work, I do a hardware reset on the the BIOS and my motherboard goes - "BIOS checksum error, loading defaults"... and my computer is back! :clap:

Gotta love them Gigabyte :francesco:

EDIT: The power supply was fried, though... I could have eventually fixed it, but I don't have an osciloscope here... from what I could see with a voltmeter, though, the IWM chip was a goner... f**king German power lines! :rant:

f**kin German lines? :Oo: have you seen Ukrainian ?
Gigabyte you say,what model you have?
what power supply you bought? :Oo:

how did u turn on the pc if the power supply was burned? :Oo:

Well... you see, the dynamo of my bike produces exactly 12V - enough for the hard-drive and with a couple of resistors and a 7805 IC voltage regulator I got the 5V out of the 12... and since the RAM needs 3,3V and I had only a 3V voltage regulator chip, I had to pull up the ground of the chip by using the Base-Collector junction of a NPN Germanium Transistor... I was lucky to have one, cause the normal Silicium-based semiconductors have a treshold of 0,6 - 0,7 V and 3,6V would be too high for the RAM.



























Naaah, just used another power supply

and in the bottom:

Press DEL to enter setup, or pres ESC to end memory test

and then nothing - the keyboard is dead (Although I tried it on another PC - the kbd is working fine) and I can't do shit

It may be, that the Keyboard is connected to the USB Port and this one may doesn't work if the OS isn't loaded.
So, try it with a PS/2 Plug, or adapter. May work then. Well, for me that worked, had the same problem.

Yep It's the BIOS chip alright
basicly your dual bios technology kinda saved your *ss
cause without it you wont have anything to work with your motherboard
it is going to be like dead
If you didn't have dual bios you would have been screwed up cuz you need a new bios chip and the firm that asembled your PC dont have the rights to disassemble your motherboard parts
judging from your chipset yout motherboard is eather biostar or gigabyte
eather ways it goes to Taiwan and the experts decide that they should give you a new one...
its no big deal but you wait for several weeks...

also if you want to know if your MB is burned out,always check if the small lamp is on,it is often close to the floppy connector and ATX power supply so when your MB goes dead the lamp goes dead too.
well,not in all cases but in mostly it does.

and another helpful advice which i recomend you to listen to.
when there is a lightning storm and your PC goes dead,open your power supply and check a small horizontal lamp.if it turned black that means a lightning stroke directly to the power cables.
if not then get your LAN card out and start the PC
In most MB if you put a burned thing in a PCI slot it usually locks the entire motherboard

P.S. Personal experience

i think it's RAM
