Does the motherboard power -on, Is the CPU installed correctly and is it rated for the board? Is the memory seated properly? I know that these are dumb questions, but they must be asked.
What is the Brand ad model of the motherboard?

My desktop suddenly suspended, switched it off by pressing the power button. Now it does not boot, the screen stays dark, though power lights on the PC and keyboard are on. What should I do?


You are the owner of a desktop PC that has developed a sudden and catastrophic hardware
fault - probably on the motherboard (since even the ROM BIOS doesn't give evidence of its
existence), but possibly in the power supply.

Desktop PC power supplies are (relatively) easily replaceable, so if you have as many spare
power supplies lying around as I do, try replacing that first - if that doesn't fix the system, then
the problem is on the motherboard.

Since your power supply is alive enough to light the power LEDs on the system unit tower and
also the keyboard, the problem is probably on the motherboard - look at it - there may be an obviously burned visible component - but there usually is no visible sign of the fatal failure.

The reason I do not suspect your HDD (hard disk drive) has crashed is that ROM BIOS
executes at (power start) boot time right out of motherboard-mounted ROM, independent of
whether or not the HDD is functional - and since not even the BIOS message appears on your monitor, I therefore know that the boot sequence has been interrupted long before the computer becomes intelligent enough to find and access a disk drive, and then command it to try to find a
boot sector.

How to fix the computer: isolate the boot problem to the motherboard. Replace motherboard.

SHUTDOWN ALL OF A SUDDEN WHEN I'M CHEKING MY EMAIL, I TURN IT ON, STAYS ON, CAN'T BOOT, INSERTED OS TO FIX IT BUT JUST SPIN AND STOP, POWER STAYS ON AND FANS ARE NOT MOVING, BLINKING LIGHT IN MOTHERBOARD,...


what hardware have you replaced? do you hear a beeping sound? try removing everything (HDD, DVD/CD/FLOPPY/)except the proc,video card and mem on the motherboard and try to boot. check if it will give you bios. if it still the same, do an isolation test. the main reason why its not responding is your computer doesnt complete POST. POST is one of the process the computer do to test all the hardware that is connected on the motherboard, if one fails and POST doesnt complete, you wont see the BIOS startup screen. Theres a lot of possible fault on this concern. since theres a lot of things connected on the motherboard

Gateway 5014 WinXP Media; fans run, won't boot, no screen on monitor. Replaced hardrive, same thing.


Try checking your RAM, if possible try reseating your RAM, if you have more than one RAMS try 1 RAM at a time..

Hope it helps!

Problems after BIOS update


When XP came out I quickly learned that you can't upgrade motherboards without a complete re-install of XP. It only loads drivers for the chipsets it detects on install. I've read a few work arounds but they all involve manually installing the new motherboard drivers before upgrading. I'm not positive but I think this is what you'll find you did when you upgraded your bios. XP no longer see's it as the motherboard that it installed drivers for originally and it doesn't have the ability to go back in re-install motherboard drivers after the fact. I think if you formated your computer again and re-installed XP again your would be able to see your motherboard periferals again.

Emachines wont boot


Bad capacitor(s) on the motherboard can cause this problem, corrupted BIOS maybe... try flashing BIOS.
Probably the CPU if your not getting any error code beeps on startup.. NO Processor for the BIOS instructions thus no Beeps !

Hi, When flashing a BIOS, you would need a bootable diskette (or CD) with basic DOS and the ROM .bin or BIOS update files plus the flashing software. In the CMOS/BIOS setup, you have to instruct the computer to boot first from the floppy diskdrive (or the CD as the case may be). Then run the flashing software/application and type in the filename of the new BIOS. Most modern motherboards no longer uses jumper switches to allow/disallow BIOS writing/update. If for some reason there are jumper switches, perhaps we can confirm if you would post the brand/model/version of the motherboard/computer. Post back how things turn up or should you need further information. Hope this be of some idea/help. Good luck and kind regards.
