    I came home this afternoon, checked on the computer and the motherboard wasn't receiving any power. Strange i though, the cord is plugged in. Checked out my psu and it was very hot. The computer hadn't even been on for 2 days! Plus, i heard that typically AMD computer need 400w psu +. I am running a athlong xp 1800+ processor with 300w psu . I'm pretty sure i remeber when i bought the parts for my computer, i knew i had to get a more powrful psu but i didn't bother. I got a way with it for a while. Furthermore, i do remember ocasionally where my computer after a restart would just fail to boot. I had to take out the plug for the power supply, wait a few minutes then put it back in.

    I'm wondering though, because i had an insufficient psu, is there ea change that it damaged my other hardware, or just the power supply itself?

    My model number by the way is: LC-300ATX

    What kind of power supply should i be looking at now?

    well if insufficient means underpowered, you're probably ok and you should buy either a 400w psu (any brand that has hi-pot, burn in, etc) or an antec true power 350w minimum. Make sure whatever you buy actually has a fan on it so that the psu itself stays cool. You could get by with a really nice 300w psu, but why risk it? You need to upgrade your psu anyway, so go buy one and see if that helps, if not....then back to the drawing board i guess.

    Had a computer do that for the longest time and I really thought it was the power supply. I ran into that many times. I'd just leave it off for a few mintues even with the cord plugged in. Eventually, it'd come back on.

    Anyways, one day it didn't just come back on. Replaced the power cord hasn't done it since.
    The world is waiting. I must leave you now.

    did you make sure you pluging the cpu's fan back in
    lol i made that mistake once.. ill never make it again lol
    thank god i caught i tquickly enough it didnt burn up


    also for you buying a power supply, dont just look at the watts
    look at the amperage, cause if the amperage is low no matter what the wattage is it wont be worth what you think it is.

    ??
    all atx psu's are designed to run at certain voltages, no one is going to advertise a psu as having low voltages ...of course you don't just want to buy the cheapest psu out there (which is kind of what you meant right?), that's why I recommended the true power psu's if he's in doubt.

    ahhh, sorry i realized i said votls, i ment amps lol
    you should make sure when you check the specs thats
    the amps are decent, if you dont know anything about
    power supplys you should do a search on google
    cause there alot of crappy ones out there.

    Wow, thanks a alot Waldo2k2.
    So when buying a psu, i'm not only looking for the wattage and the quality (usually estimated from the price), but also the amps. Cool, i can do that !
    Thanks guys, i'll let you know what happens. Hopefully my computer will finally boot!

    edit: And you too JarJarBinks. You are not an afterthought, just the victim of me pressing the submit button too fast

    yea my current power supply, i lucked out with, i had no clue
    about amps and stuff when i bought this power supply
    its 500W power supply i forget the brand anyways
    my friend told me about the amps to check then
    and he said for the 12V 18A or more was better
    and mine has 25A, so that made me happy lol

    to read the specs, you have to click view images, then look at the close up of the specs on the white box...my eyes are bad so I couldn't tell you what it is off hand.

    AMD and Intel both have web pages that have recommended power supply manufacturers on them. Not suprisingly the lists are very similar.

    I havn't had much time to work on the computer, but tonight i did. My computer is still not working but i'm making progess =D

    Anyways, i wanted to try a bench test, after it being recommended, except my mother board wont' come out! I've unscrewed ALL the screws, checked it over so many times to see if there was some i forgot, and there is no plastic plugs. It seems to be stuck near the I/O ports. There no external devices plugged into it though. Any ideas?

    Arghhh, its probably one of those pesky I/O shields. There are usually little metal tabs and whatnot that might get jammed into a port or around a port. I run one of my PCs without one because it was too challenging to get the motherboard in with the thing installed hahahaha.
