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...
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...
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
20mA peak current
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...
aye i thought of that, but when i posted that i had just gotten off work and was tired got some rest and now im bout to.
anyone got a tool that can tell ya the memory info in windows, i dont feel like restarting it right now to find out dling shizna from a boys ftp and its 70% done.
My pc is pretty good it does what i need it to but i'm thinking about selling it all i really want it for is playing world of warcraft and i think its a bit overkill for the game cept video card wise.
I was just wondering if i should sell my system and what kind of money you think i could get...
i've got 2 years of a+ cert
1 1/2 years field experience in a high volume repair enviroment
tho most of my time is actuallyy spent troubleshooting electronics which sucks cause i get to do less and less pc repair at work each month
but yeah ya do tend to forget things.
now that its summed up to a memory issue, if your sure its seated right then you can have some bad ram sticks.
The amount of static electrcity it takes to actually fry one of those ICs is so small you would never actually feel the shock.
Since you have 2 sticks just try them 1 at a time
Instead of just guessing on what it is do you happen to know what bios you have.
If so you can look up the bios beep code and it'll basically tell you what to look for.
I'm surprised no one mentioned this already its one of the first things you learn to do in a+
You can find the bios...
I'll post this simple thing
Go into the bios and on some socket 370 bios i've seen they have a mode pic or apic mode
Apic mode = multiprocessor system if its set to pic then u'll only be running 1 cpu.
Always start with the simple things before you worry about the OS.
study this, its a few years old and i can tell you from seeing this and actually having my a+ cert these are dead on from the test i took in 2003, the test has changed and so have the questions but this is a good example...
Download this tool, install it, it'll create bottable floppys but its only a 30 day free trial i believe it may take 20 or so minutes the hard drive test surface test is why it takes so long.
This will tell you...
I'd upgrade scavange what you can sell it for money to fund the new systemand not look back.
And being an electronics technician i hate this idea of water cooling, water + electronics equals system dead. it only takes one liuttle leak to kill your system.
I like the idea of having massive...
