Single Status Update
So in my vast efforts to finish college I recently enrolled at UMUC (umuc.edu) which offers a wide online-based cirriculum which enables me to keep working part time and still take classes. Currently I am only signed up for one course that is only one credit and takes only 4 weeks to complete. It began at the beginning of this week and I was looking forward to doing my best at it.
Needless to say my laptop has been dead for the last couple of months (I'm under the impression the CPU is dead - the disk drive whirs and whatnot but the screen doesn't even turn on) so I've been planning on using my desktop computer at home. The connection on it is iffy, though I think now all I really need is a ned ethernet cable.
Except as of last night IT won't turn on. Rather, the screen flashes the neat little Intel 4 logo at me, then just sits there. This happened as of last night. Now I can't get school work done at home and I'm aimlessly writing this with what spare time I have at work. I don't have the money for a new laptop/desktop and while it may just be the hard drive failing on me (as three have done so in the past year alone) I can't even afford a new install of Windows, let alone a new hard drive, since I'm currently managing my student loan repayments.
Yeah, this is pretty much just a vent, but I'm steamed as hell over it. I'm now going to try and get as much school work done as I can before I actually have to work because as of now that's the only option I have for accessing the internet.
P.S. @TGH - Sorry I couldn't get my CC4 map done :(

What if a terrorist is threatining to detonate a nuke in NYC if you don't use a capacitor with lower than the rated voltage, or significantly higher capacitance?
Depends on how badly I need that shitty P3 mobo of mine to work.
Jokes apart, using lower voltage than the rated one means the cap will pretty soon gas out, leak or explode. You might as well never had replaced it.
Higher capacitance means that the voltage stepping circuit the cap is part of will generate a higher output voltage, and that it will overpower and fry any components depending on it (including RAM sticks, CPUs, onboard cards etc.). Not a pretty prospect. You might be able to correct for higher capacitance if you manually lower the CPU or bus voltage in the BIOS a few notches, to compensate for the different voltage output, but only if you know that e.g. the cap you replaced was part of the CPU's voltage stepper.
Just confirmed it over the weekend - the MoBo on my laptop is definitely gone. United Bank of Parental Funding has agreed to get me a new one however, so not all is lost.
I hope you enjoy soldering.
Never soldered a thing in my whole life, so yeah, I have no clue what to do or how to really do it. My neighbor has a soldering iron that I could borrow, but short of someone holding my hand each step I wouldn't have a clue what I was doing. I may try anyways because short of that I'd just take out the hard drives and then recycle the whole thing at a local Best Buy anyways.
Start by practicing on a board that's already been junked, since your first attempts are bound to be a bit rough. If you can also borrow some solder wick or a solder sucker - that'd help. Is it a temperature-controlled iron? Whatever you do, don't use a plumber's iron, that's bound to burn a hole straight through the board if you're not careful.
