Unable to restart desktop and light flashing

OK for about a month now when i shut down and my computer switches off i get a flashing light where the on/off button is. is is when closing down normally by start menu.

Then i am unable to restart it by pressing the start button. have tried taken power cord out and switching switch at back of pc to stop the flashing but when connected up again it continues to flash as before and unable to load up.

I thought it might be the onboard battery so bought a new one and the same thing happens. however the only way i can get teh pc to work each time is by actually removing the onboard battery (even the new one) and the waiting a bit and replacing it and putting power cord back in and then pressing start button which works. but this means each time having to go inside my PC and doing this choir. plus then i have to redo my bios settings each and every time and set my clock.

anyone know whet the problem could be

thanks in advance

 

Please post what type of system this is, so we can better help you. And also, what color is the flashing light? green, blue or amber?

 

It is a blue light, but blue is teh only colour possible of the two there. no other colour is possible. it is normally a light to indicate power on. the power supply is under a year old.

i have a desktop p4 3.2ghz.
i have 4 1 gig sticks but 3 are shown as it is a 32 bit os.
windows xp

i did a thing on here once that listed all about my pc using everest so it is in a past message also

 

11-11-09, 23:20 is the time of post of mine with everest attachment/. hope this helps

should i do another new one?

 

if you go to the manufacturer's website, you might be able to research the flshing light. You would want to search for something like....Diagnostic indicators, or Diagnostic Power Light, or diagnostic LED's. Hope this helps

if you haven't changed hardware, it's probably fine.

Is there a pattern to the flash? short short long long long pause short short . . .

Only time I've had a flashing light like that it was a hard drive issue

 

Hi guys

cant go to manufacturer as evesham where i got my pc do not exist anymore.

my motherboard is a Microstar i think.

the flashing light is more random that anything but short burts but many like 1 every 2 secs.

when it happens it will happen all night and i cannot start up computer, even when i switch off back and back on it resumes. When i take the cord out and with off switch and put back it still resumes, even after 30 minutes.

seems the only solution is to remove the internal flat battery for more than 20 secs. to get it started after then putting it all back.

this flat battery is new also as i had thought originally it might be that that was the issue.

I thought this site that has always helped me out before will be my best chance of finding out what really is the problem?

when it started to happen about 2 months back i had no new hardware added and did not make any other system changes.

any ideas?

thanks

 

Ok unable to fix so bought a new pc bough a caddy for the hard drive and access is fine. so it must have been something wrong with the hardware? or startup.

thanks

 

Sorry I'm late to the party.

Since you've already replaced the PC this may be a moot point; however if you or a friend want to take a shot at bringing the old one back to life I would look at the power supply.

Besides going "POOF!", power supplies sometimes fail through a gradual drop in voltage (think of a car battery. The car may run fine until you shut it off, attempt to restart it and hear "click, click, click"). I have seen this type of failure cause issues similar to the ones you have described. Once the capacitors in a near-dead power supply cool off after a few hours, they may once again have barely enough juice to power up the system.

If you can borrow a known good power supply from a friend (or buy one from a store with a decent return policy if it turns out not to be the issue), do so and hook it up to the old PC. Even without the hard drive installed, it should still start to the point of giving you a "disk error" message. If you can turn it off and on this way a few times without unplugging or removing the BIOS battery, the problem is solved.

Don't feel bad if this works. I've used worse excuses in the past to "justify" a new PC or upgrade parts when I wanted them. LOL

If you try this, let us know if it worked. Thanks.
