Computer will not run. Monitor will not run.

  1. Hello.

    I have a crucial problem with my desktop computer. It just won't operate.

    I found out this morning, when I got out of bed. I left my computer on all night, with monitor off, (as always).

    The red power light (or loading light) is on (on the computer), although it is supposed to be flickering, it is not. Just staying red. The monitor is blank (black) and theres a red light insted of the green one.

    There is no way to turn off the computer, other than swiching the swich on the back of the computer. Holding the "on button" to turn it off, will not work, (it should). Other than that, the fan runs, all cords are connected.

    About a week ago I got my new 512MB BFG Geforce 7600 GS OC AGP, replacing my Nvidia 6200 AGP. My new video card runs great, but I wonder if it could be my new card frying or something, mabye a power supply problem? Mabye some hardware component is out of place?

    This is very strange, because I never did anything to it, I just left it running while sleeping, as always...

    My desktop specs:
    - 1 GB RAM pc3200
    - 512MB BFG Geforce 7600 GS OC AGP
    - Asus P4S800-MX (SiS) Celeron D 2.5GHz
    - Old sound card, 6 channel

    I have tried taking out the BIOS battery and putting it back in, although I have not yet tryed putting in the old video card and trying a different monitor.

    Thank you for any help, and I will reply to you guys ASAP.

    It sounds like the power supply to me although it's possible something else might have gone with it.

    All the information will be on the sticker on the side of the psu.

    Ok, the model of PSU is LC-B450E

    It says the total output maximum is 450w...the video card reccommends 350w

    I have tried swiching the video cards but it did not work. I have although, found that the power supply box is very noisey and very clunky sounding (not normal)

    Can someone tell me if this is a power supply issue and mabye I have to buy a better one?

    This is the info on my PSU sticker, I have no idea what the heck this means:

    Voltage Currency Frequency

    V- Input 115/230V 10/5A 60/50HZ

    V output 3.3V | +5 | 12 -5V | -12V | +5VSB PS-ON | POK | COM
    28A | 50a |18A O.8A | 1A | 2.5A REMOTE | P.G. | return

    Max 230W 216W 4.0W 12W 12.5W - - -

    Ok, so if my PSU has crapped out, do I have to buy another one or just clean it out. Also, how do I know wether the new PSU will fit in my computer and is 500W (or more) good enough to handle my computer.

    edit: sorry, making that chart in the post window didnt turn out so well, sorry..

    Based on everything you've said and what others say, I would tend to agree this sounds like a power source issue. Can you post what brand of PSU you currently have? I haven't seen that yet..

    If your PSU has died, you need to replace it. You might get lucky and get another short period of life after cleaning it, but I emphasize lucky and short there. 500W is most likely sufficient for you, however in my experience you're better off getting a name brand 450W PSU than a cheapo 500W that will work for one day longer than the warranty and die. Name brand 500W obviously gives you more juice, etc. A lot of how I would rate "sufficient" depends on any other cards and drives you have in your system- the more you have, the more you want to consider a larger PSU. There used to be a good PSU calculator around, I've lost the link. Does someone still have it?

    As far as will it fit in your case- see what type of case you have (AT, ATX, Micro ATX, etc). The PSU will specify what type of cases it will fit. Most of the time, unless you've got a Dell or Gateway case that uses a proprietary PSU, ATX will fit.

    As a barebones test, you could remove all drives from your power supply so you just have your video and mobo hooked up. See if you at least get a POST beep. If not, what behaviors do you observe (blinking lights on anything, other odd noises, etc.)

    Hope this helps some...

    Thought you'd never ask.. :D
    PSU Calculator: http://www.extreme.outervision.com/psucalculator.jsp

    Although take account that it will give you an estimate, so on the safe side add 50W or 20% (whichever is greater) to give you your minimum needs (and a bit of headroom)

    Ok, well I just put in two other PSU's, both of them able to run my computer, but no luck. Same problem. Although with one PSU I tried, my CD and DVD drive sounded real weird, like a clunky motor, which is defiantly not normal.

    There is no beep at system startup with any of the PSU's. What could cause no beep at startup?

    We never did hear back, what happens if you unplug everything but motherboard/cpu and try to power up? If you get a beep or any sign there, what happens if you add the ram? If you get a beep to start with, add things back one piece at a time until you get no response, and you'll know your offender.

    Let us know if you do find the culprit!
