odd behaviour....

[Shiori]

whenever i open up my PC to add/remove peripherals, or do some cleaning...after i put back on the cover and fire up my PC, it wouldn't boot up. I don't even get the memory check screen, the one with the Energy Star logo....just.....NOTHING. but after i leave it alone for a few hours, say, after arriving from school, it works, but sometimes i even have to wait for days before it finally fires up. what could be the cause of this odd behaviour? it only happens when i open up the pc. :confused:

[Xeven]

maybe you need to do a cmos reset or sumthing...

[Shiori]

a cmos reset? how do i do that? :confused:

[Xeven]

there should be a reset jumper besides your bios chip.. set it to reset.. but i dunno if it will help, since i don't see the whole picture... :p

Sounds more like its overheating to me. By leaving it for a while it gives it a chance to cool down and then it works ok til it heats up again. Open it up and check that the fan on the cpu is still attached correctly and powered, then switch it on and check that it is actually working. If its faulty replace it.

[Shiori]

overheating? :confused:

it's like this:

i boot up the comp in the morning and get emals/go to Emuforums/play an hour of RPGs

i go to school. i pick up a new CD reader or something like that.

i go home. the comp's pretty much cooled down after 10 hours.

i open up the case and install the thing, or whatever.

i boot up. nothing happens. i check the video card (must've been disloged while installation of peripheral. still nothing happens. :confused:

i get frustrated and sleep. ;)

when i wake up, i try again. sometimes it works, on rare occasions it STILL doesn't work. :( Havta wait for DAYS. :(

....and what's really weird is that the exact thing it also happened on my other computer. :confused: i really wonder what's up with it....

[Betamax]

Well that might just remove the overheating glitch. Might be environmental. Once heard of someone whos interferance from their hifi system kept sending a soft reset to the mobo. :confused:

[Shiori]

hmmm....well i guess so. it's pretty hot over here (35 degrees celsius) all the time, so that must be phucking up my system at times. but i dunno why it decides to act like that only when i open up the case... :confused:

An old computer I used to have went into fits whenever it was summer. The fan was fine any other time, just not summer. It was humorous in a peculiar sort of way. I should also note the monitor for that computer started displaying everything in purple. Stupid Packard Hells.

[Xeven]

purple usually means the BLUE electron gun isn't firing.. if i remember correctly.. stupid brain.. is pretty fried.., anyways, prolly a worn out trimmer or a cracked pcb trace, that's usually the cause.. maybe im wrong.. hmmm... :)

Keiichi, what mb are you using?

[Shiori]

the one im using right now is one of those first-generation Slot 1 mobos. :p :D :D :D

....the other computer is a PC partner board with built-in sound and video (i was penny-pinching back then. :()

[Xeven]

maybe its the boards then.. unstable maybe? :p

[JuniorCRB]

what kind of computer is it? have you checked your bios? make sure all your connections of tight (on the motherboard)? if you don't have a clear cmos jumper (case on some old pc's) you could remove the cmos battery for 20 sec then put it back,

a simmilar thing happened to me at work and all that was needed was that the operating system needed to be reinstalled.

[Shiori]

yeah, they're pretty tight connections. haven't tried the cmos battery trick though....would the mobo...or at least the cmos time be phucked up if i remove the battery for that long? :confused:

[NickK]

Try disconnecting the power and IDE cables to the CD drive you acquired, then try booting to see what happens.

no.

[NickK]

I don't think that you need to reset you CMOS. Save yourself some trouble and don't pull the battery.

[Shiori]

i don't think it's the peripheral's fault. Just removing the cover from the case, then putting it back on induces this problem. :(

[NickK]

Are you sure? Try detatching it just to be sure. Also you might want to try running the computer without the case cover for a while. You just might need better circulation. Hehe, I got some good case mod ideas for you :) ... I think!

[Xeven]

my theory, the mobo itself is unstable, and is now at the terminal point of its life... nasty.. hehe :evil::evil::evil:

[NickK]

It's going to have some problems if the power supply can't keep up with the addition of new equipment. What should really be done is to completely disconnect all devices that are connected directly to the power supply and motherboard. If the computer boots OK then there must be a problem with the device or the board. Plug everything back in one at a time testing as you go along.

dunno about that, since it also happened to the PC PArner mobo i was teling you about while it was just a month old. :confused:

Nickk: i only got a CD reader and a harddisk plugged to both IDEs, with the HDD to the primary. Aso just replaced the Power supply with a 230W one from a 200W.

[NickK]

Since you reported that this stuff occured after you got the new CD drive, I'm just assuming the computer was working normally before that. Don't you think that if the computer were to suddenly stop operating normally after you put the new hardware in that there might be a slight chance that the hardware itself is actually causing a problem? Just an idea. I think you really should try my earlier advice and see if it works out. I don't recommend buying a new motherboard until you test all of the possible options that you have available.

You might also want to consider getting a better cooling system for your system. You could try to drop the tempature in the room to see if that makes any difference (this is the easiest test of all.) If that does work out, perhaps you should look into it?

[JuniorCRB]

Just curious, how much power does your power supply output?

[JuniorCRB]

i mean with its current peripherals

[Shiori]

i dunno, do you know a way how i can determine that?

anyway, im sure it can handle the stuff in my comp (PII, CDROM, 1 hard disk, 1 floppy. The monitor is directly plugged to the UPS.)

[Ryos]

Keiichi: the information may be on a sticker somewhere on your computer (mine is on the back).

[Shiori]

oh....hehehe, i misread that. :emb: i thought JuniorCrb were asking how much power the connected peripherals actually use.


....well, like i said to Nickk in an earlier post,

Nickk: i only got a CD reader and a harddisk plugged to both IDEs, with the HDD to the primary. Aso just replaced the Power supply with a 230W one from a 200W.

a friend of mine had the same prob.....NEW power suply unit (that thing where you connect the electricity plug).....(not sure if it is the same prob though...see if you can get one borrowed, just to check it ), before you have to buy a new CD rom....but i guess that would asking to much of bad luck (like my friend)...
