Another Exotic Problem :)

I have a compaq sr2010nx that is running windows vista.the place where the monitor hooks up had gotten broken off so i just changed out the motherboard.....I know maybe not the best way to handle that but well i had one laying here(LOL)......after i installed new motherboard.I turned the machine on and it worked perfect for bout 10 min,then it just froze up.I turned machine off and turned it back on but now it want power up the monitor,also when i plug power cord to it the fans kick on i have got to hold down the power button to get them to turn off.once i do that it will turn on and off with power button but the monitor does not come on.The yellow light on the monitor does not turn green.I tryed the monitor on another computer it works fine,i also tryed the hard drive it to is working fine.any other ideas as to what may cause this
Thank You

 

I suspect 2 issues. (neither of which I will attempt to solve myself ) One is that there may be an issue with your bios when you switched MOBOs and the other may be a windows issue. A lot depends on what version of windows you are using and whether you are able to simply switch MOBOs without doing something about validation of the OS. MS will usually allow that if it is a result of a defective MOBO.

This needs someone with more expertise and they will come along I am sure.

 

Thanks ...also i made a mistake up there,the o.s. is xp not vista..but i think you are right because when i got it to come up the first time i had to validate windows

 

One problem has been outlined here. When you install windows it records the parts in your pc, mainly your motherboard. This is so you can only install windows to one machine and not use the same key over and over again in different machines. When you swapped the motherboard, windows sees this as now being a different system, causing a revalidation.

This alone though, would not cause the monitor to stop working. Have you tried resetting the BIOS by removing the battery for a minute then replacing it, whilst the machine is not plugged into the wall of course.

Were you sure the 'new' motherboard was in working condition before you installed it?

 

as for as apperance they are identical and i have checked all plugins to make sure they are secure.I have also tryed removing the battery to with no luck.The strange thing is like i said it worked for a short time then just froze up.
I seen a thing on someone elses forum about taking out the battery and leaving it out for over night,and it fixed their problem.I left mine out for about an hour then replaced it,does anyone know if maybe it just needs to be left out for alonger period of time

 

Nah, it really only takes a few seconds although you may want to try switching the battery as long as you have more than one.

 

no luck on battery swap but i did just notice also that the little power indicator light on the front of the computer is not on .....does that help anyone with diagnostics

 

i just checked that again,there are 2 plugs on the hard drive...they are the sata plugs both are secure.....one more thing that just dont make since is why when i unplug it and plug it back in does everything turn on ....shouldnt i have to plug it in and then turn the power on for this to happen

 

There has to be more than just sata sockets. How is it getting any power at all?

 

one of the connectors goes to the powersupply and the other connects to the motherboard.that is how it was hooked up before and it worked.

 

Your Motherboard

Your power supply converts Alternating Current to Direct Current (Unidirectional flow). Polarity of your front panel connections is important.

 

i hate to keep draging this on but it's bout to drive me nuts(LOL)but why would it have worked for a few min and quit.I mean could i have done something and messed up the mother board

 

Static discharge can and often does damage components. That's why we either use a ground strap or touch the unpainted surface of the case before handling components. Though we hope not, it is possible. This suspicion may be premature. Both the ATXPower1 and ATX12V1 connectors are plugged in ? The polarity of your front panel connectors are correct ?
