Amd started out as an intel clone company when they went into the home market, cause they do make more the computer processors they make a wide range of ics for electronics
Easy way to test your power supply unplug it from ac and mobo
take a paper clip and jumper the green wire to the grey wire, plug the ac back in,if it turns on that means the power is good.
Its most likly a dead mobo, even if no caps are burnt up it dosnt take much to fry one of those...
1st.
Swap out the video card it could be that
2nd if the video card didnt fix the rpbolem check all of the voltages on the PSU, the powersupply can turn all of the fans on and still be bad. It needs a signal (power good) to fully turn the system on, i've seen about 20 PSUs at my job that...
Without schemetics, and surface mount tools, and a good understanding off electronics theres no way ull ever fix it.unless its jsut one of the 4 pins on the power connector.
just remeber to add up the current of each branch to get the total and make sure you dont go over the power supplys max on the 12v rail
also why only 1 resistor on each path in parallel voltage is the same on each branch thats on parallel to each other.
So in that setup theyd all get 12v...
I was just using the source voltage as an example
Also if you wire these up in parallel you can put more then 3 on a line
Because in a parallel circuit voltage is the same accross each branch.
So if you have 5 branches each line will get 12v then you cabn have a resistor and 3 leds on...
The optimum settings
are 3.5v
20mA peak current
so
using ohms law
V / I = R
12 / .02 = 600Ohms
If i were wiring that up
i'd go -
negative - LED - LED -LED - 600ohm resistor - Posiive 12v
/\ - LED - LED -LED - 600ohm resistor - Posiive 12v
/\ - LED - LED -LED - 600ohm...
just look for a different style momentary switch most radio shacks stock them and chances are ull be able to find one that is quiet and that will fit the mouse.
Iomega 100Mb Zip Disks
I have 40 or so all untested.
Pm with offer if ya let me know how many you need i can test them for you i do have a zip drive lying around and if you want them tested i will test them.
No digi cam right now but i'll try to post pics tommorrow if at all possible...
