I placed the motherboard into a new case. I think the new case had a defective power switch. it would not start. I put back in the original case and the computer attempts to start and stops and keeps repeating the process over and over. is there something wrong with the motherboard?

    Generally this is due to bad Electrolytic Capacitors on the motherboard. (Radial Aluminum Electrolytic Capacitor) More specifically the ones in the motherboard voltage regulator circuit, and even more specific the one's that control the voltage regulation for the Processor. I would like you to unplug the computer from power, and take a real close look for visual signs of capacitor failure. Post back in a Comment.

> attempts to start and keeps repeating

Please be more specific.

Do you get the initial "splash" screen, and then some white-text-over-black-background,
giving RAM size, processor ID, and such?

Do you see the "press DEL to enter BIOS SETUP" message?

What else do you see?

Is a disk-drive attached to the motherboard?
Does the motherboard try to boot from that disk-drive?

Weird start-up problem


Recheck all your board connections. I missed a connector by one pin and got nothing as you have. Once I realized my mistake and re connected the plug on to the board correctly everything worked.

Not getting any video from a msi 880gma-e55 integrated video motherboard


This may sound simple, but make sure the monitor is set to correct input. Many are auto detect, but you never really know.

You could also check BIOS for onboard video. Disable if you have an add-on video card. Enable if you don't

Reseat the video card if it an add-on.

My mom's acer aspire 7720-6712 has a defective power switch. She took it into an independent repair shop and the guy super-glued it on (can you imagine why he is now out of business). 6 months later she is...


I LOOKED ONLINE FOR POWER SWITCH BUT I DIDN'T FIND ANY. I CAN FIX IT BUT SINCE I LIVE FAR FROM YOU, I THINK YOU DO NOT NEED THE ORIGINAL POWER SWITCH TO TURN IT ON.
GO TO ANY ELECTRONIC REPAIR SHOP THEN SHOW THEM THE POWER BUTTON ON YOUR
LAPTOP AND TELL THEM TO BYPASS IT WITH ANOTHER TYPE OF SWITCH. IT IS JUST SOLDERING WIRE FROM THE MOTHERBOARD(A PLACE WHERE THE SWITCH IS CONNECTED TO ) TO ANY I/O SWITCH. ANY MICRO OR SMALL SWITCH WILL BE FINE. SHOW THEM THIS POST IF POSSIBLE TO UNDERSTAND WHAT I AM SAYING


PLEASE RATE IF THIS HELPED YOU.

I just finished building a PC using motherboard Biostar N68S, but it won't power up. When I push the power button, it only works for 1 second. Everything is connected. What seems to be the problem?


Try to verify these :
1- Check that all perepherals are connected correctly (HDD, Drives...)
2- Check taht the motherboard support the CPU you are using.
2- Check that the RAM is correctly inserted (use an other connection slot)
3- Check that the CPU is correctly inseted and that the FAN is correctly placed
4- Check all USB port, may be there is a short circuit.
5- Check your AC Power.


Good Luck.

Things to consider when replacing a 5600G case


I assume this is an ATX motherboard. Most cases should work. I think most cases come with a power supply but if not make sure yours will fit. I like cases with at least three drive bays which give room for expansion. The biggest problem I see with switching cases is connecting the wires for power button, hard drive LED, re-set button etc. to the motherboard. Maybe you will get a schematic with the case. Some boards are not marked very clearly in this area. You will need a magnifying glass to read this information on the MOBO. Trace the different colored wires back to the case to see what they do.

I am looking for instructions on how to replace my e-machine atx-250-12e power supply connection.


they're pretty much all the same.

open the case. pull the 20/24 pin power plug and optional 4-pin power plug out of the botherboard. Remove power plugs from fans, hard drives, cd drives, etc.

unscrew the four screws anchoring the power supply to the case. Slide out the power supply. Put a new one in it's place, the screw holes will line up. Then reconnect the power cables just like they were when you removed the old one and boot 'er up.

All you have to do is make sure the wattage rating of the power supply is higher or equal to the old one. Your old one is only 250 watts. You will have to search VERY hard to find one that low, so don't worry.

E-machines doesn't make particularely powerful desktops so you won't have compatibility problems. Almost EVERY atx psu on the market will work.

Asus A8N SLI DELUXE MOTHERBOARD AMD PROCESSOR


When you reinstalled the processor, did you put thermal compound on it? Not putting thermal compound on an AMD processor could burn it. I've tried this before, thinking it was okay since i tried an Intel not placing any thermal compound, and there was burning smell on the AMD processor. If the problem before was the power supply, you might also want to check the motherboard. Defective power supplies destroy the motherboard as well. You may also want to check the if the power button was placed back to its pins. You may have missed that or the wire might have come loose.

A new motherboard for a old compaq presario 5240


You will need a new case and a new power supply. I would replace the memory as well.

Compaq had a tendency to make cases to only fit their boards back then. Youre better off building a new unit and starting over again.

I think that you have a faulty power switch there. I know it is new but there could still be a fault. Suggest try a new power switch as for the earthing check that the motherboard screws are all in place and secured to the case.

Cpu cannot boot


Hi, the most likely place(s) where a spark could occur on your motherboard would be near the processor where the big transistors are, the capacitors. Such if it were the case would mean that your motherboard is most likely fried and therefore would require replacement. Check if there are any burnt marks or try to smell the motherboard. Arcing (spark) would leave a telltale burnt smell within the immediate area. Another likely place would be the capacitors themselves (3300uF/6.3V or something like that). Normal capacitors would have flat surfaced end with an indented X or T mark. If any would show a bulging, cracked, open or blistering open, then chances are they are busted, leaking, shorted - all meaning motherboard replacement. Aside from the motherboard, it might be that the power supply itself is defective. Normally (but not always) spark/arcing would occur in the hotside (the one directly connecting to the mains). You are probably better off buying a new PSu rather than have it repaired. In some cases, PSU with on/off master switch at the back have been known to have arcing/sparking problems. In this instance, switch replacement is possible without replacing the entire powersupply. In extreme cases, the said switch can be left out (removed) and the two wires going to it just twisted together and taped. Again this is on the hotside. If you are not comfortable working with power supplies, may I suggest you ask a competent service personnel to do the repalcement or removal and shorting. Hope this works out for you. Cheers.
