Installed new Power supply, Monitor stays in standby...? So I noticed my fan was starting to go out, then it actually went out, my power supply would start to over heat and the cpu would shut itself down when it got too hot. Could this have damaged my motherboard or video card? I bought a new power supply and the monitor would just stay in standby. -I tried a better power supply and had the same result. -I tried a different monitor (both are pretty old) same result-standby. -I tried my older video card (which if I remeber correctly was working fine the last time I was using it I just upgraded) same result. Can old monitors be uncompatible with the newer Power supplys/mother boards/ video cards (all 3 Power supplys were ATX)? Could I have damaged somthing because I didn't replace it right away? I'm stupmed on this one any help/suggestions would be much appriciated.

    Thanks for the help guys



    Id have to get back to you about the exact specs(I'm at work and don't recall) It's not a dell though, hate em. I do know its AMD though. Video card uses VGA software..



    My cd/dvd/rw drives' lights turn on and they keep repeating the same blinking pattern as if they are trying to read a non existent cd/dvd. Correlates with repeating sound. The main power Led lights on the tower turn on. There is a small light on my mother board that Is yellow i believe. I don't think i would hear the windows start up until after I select my profile (that I cant see...) but i haven't tried to simply just press enter... The fans turn on.. except I haven't really checked the one on my video card. Not sure it normally would start at boot anyway.



    Castaroy I think your right. I guess that was my main question "Could I have damaged something because I didn't replace it right away?" It does seem like I fried my processor... Any recommendations?

    What model system? or model motherboard?
    What video card?

    Some older Dell systems had proprietary wired ATX power supplies that required a Dell PS or an adapter (Standard ATX would connect, just not work)

    When you power on with the new power supply, do you get any indication the computer is functional? Do you get normal lights/fans? If the speakers are connected, you you get the Windows startup sound? We need to determine if we have a no post or a no video situation here.

    Did you ensure the 4 pin 12 volt connection for the processor is connected to the mothertboard?

The failure is most likely the motherboard, the processor would be a 2nd point of failure, but generally processors failures are uncommon (I do admit AMD seems to have more processors fail than Intel) I'd replace the motherboard 1st, before buying a new processor.

Don't like Dell, get a replacement eMachine for $298

Your problem is either the processor or the motherboard. that is why your monitor is not getting any signal. first try to replace the processor because I suspect that this might be the problem as it has gotten overheated before. if there was a power problem with you power supply you monitor would not power up at all.

Hi David,

Try removing and resetting the CMOS battery on your motherboard. Also, make sure that all connectors from power supply are plugged into the motherboard. There should be power for sys fan, CPU fan, etc.

Thanks,

Try connecting the monitor to a friend's computer. If you get some sort of a display it's not the problem. When you say that the computer makes a new noise like the fans are spinning fast, you might have an issue with the video card , motherboard, or power supply.

Power supplies tend to be either working or not working. I would start with the computers memory, reseating the memory cards (there are plenty of tutorials on the web for how to do this). If the power supply fan was running, chances are you did not need to buy a new one. Does it do the same thing with the new power supply?

Disconnect everything from the motherboard except the power supply connections and cpu fan. Install one stick of RAM and connect your monitor. Then try starting up. See if you get any BIOS boot messages. This will tell you that the board and processor are okay.

With what you say you've tried already, I'm thinking you might have a bad processor. Most every other problem would result in some kind of error like POST beep codes or messages on screen. If the system still doesn't boot with the bare minimum parts installed, replace the processor.

Plugged up came on about 20 minutes later shut down and went to a yellow blinking mode monitor stays yellow i unplug monitor from cpu and works good do you have any suggestions


Could be getting too hot. Make sure all fans, cooling fins, heat sinks, HDD vents and weep holes are unobstructed and clean. Many computers have a BIOS screen at startup that will display system temp. Start it up and enter the BIOS, check CPU temp. Most PC's will shutdowm or reboot if temp exceeds 140 (this can be adjusted).

If not overheating, could be fault in a memory module, HDD failure, or CPU itself. But that's not that common in the scenario you're talkin about

My computer wont turn on


Remove the power cable and hold down the power button for about 30 to 60 seconds. plug the power back in and see what happens. If fail look at the back of your computer ans make sure that the fan for the power supply is on. Also make sure that the red switch is set to 115V and not 220V. This is also located in the power supply.


If al has failed your power supply is no longer working and will need to be replaced.

E-machine will not power up even after replacing the power supply


If power does not come to hard disk, cd/dvd etc. then replace the mother board. And if you can put on the cpu and there is no display, then replace the RAM module.

Wont start up


my wife has a presario that had a similar problem - it would boot up, then immediately shut down. I took off the side plate and blew off some of the dust inside. that worked for a couple of days then the symptoms returned. I took it apart again but this time I removed the cpu fan and the cpu heat sink. I cleaned all the **** off the fan and the heat sink and replaced it. this time it stayed on. I checked out the power supply. compaq installed a very cheap power supply - only 250 watts. a replacement power supply for the same machine but with an output of 300 watts is available. as soon as I can scrape up the change, I'm gonna change the PS
