Computer won't boot

Likes # 0

Our computer is starting to not boot up. When the on button is pressed the fans start up and the hard drive activity indicator is on and steady. there are no beeps, the keyboard Num/caps/scroll do not flash and the monitor is blank. It takes quite a few attempts to power off then on before it boots normally. Once it has booted then the computer runs without fault. I have changed the power supply. Whilst trouble shooting i have tried removing the ram and tried them individually and in different slots. I have reseated every plug, unplugged all usb cables, even disconnected the HDD and DVD drives then turning on. I have removed and reseated the processor and removed the button cell and checked the voltage at 3v. Any ideas please?

have you tried taking the motherboard out of the case, and hooking it all up, it could be a short caused by a design, or misplaced motherboard riser. it could also be you are overclocking. ram , or the settings for the ram. do you know if you have updated anything right before the problem starts, do you have a easy bios auto updater? any other auto updaters?

Try this: Unplug all peripherals, Printers, screen, USB attached devices etc. Remove the power supply lead. Hold the power button for 40 seconds to a minute. Re-attach essential peripherals like monitor, keyboard and mouse etc and reboot.

When this happens do you by any chance have an external HDD attached by USB? This could also be the cause of the problem.

If you look at some similar questions on Google the answers and solutions seem to boil down to 1. Failing Power Supply (but I see that you have already changed that. Was it a new one?) or 2. Failing capacitors on the motherboard - how old is yours? or 3. In one instance it was associated with the motherboard USB to front panel USB plug/socket being out by one pin - although that seems unlikely in your case unless you have moved them around.

chub_tor is correct and for info my offering was to sort the capacitor problem. I didn`t think to ask if it was a new PSU though!

Clearly with the Age I agree the most likley problem is a capacitor problem. check carefully for domeing or leaks.All the information give including the repeated rebooting points in that direction.

If the capacitor,s are damaged unless your an expert I would suggest its time to upgrade, Look around a new system may be cheaper than to replace various bits

As you have checked out the most obvious items, and you appear to have good working knowledge , it might be time to get a new motherboard. I would suggest a motherboard Bundle, then you can use your old Hardrives, monitor,keyboard,mouse etc.

This isa company I have used may times and had good service,[link text][1]

[1]: http://www.microdirect.co.uk/Home/Search/Components/Motherboards?answersort=Price+(Ascending)&answersper_page=20&source=googleppc&gclid=CO-kkcGZgKkCFQoa4QodXXBXSw called Micro Direct, and their prices are very reasonable.

If you have a XP CD , it might be easier to rebuild to a new drive, or possibly you could borrow a Cd and use your number as printed on the case. You may have to re-register your XP home as it is clased as a new system

Thanks everyone for the replies and ideas. I will try and answer them all with this reply. It was a new power supply i fitted. I forgot to mention that most of the time the computer boots first time and started playing up about a week ago. I replaced the motherboard with a bundle when the original Intel chiped/Gigabyte motherboard failed completly. The CPU, motherboard and Ram are all about four years old. I can't see any of the capacitors bulging on the ends though this does not mean that one is not failing. I did try removing all of the peripherals except the monitor whilst i was trouble shooting. I am not overclocking anything and i don't remember updating any thing immediatly before the trouble started. I might try and remove the motherboard and check for debri or signs of shorting. I might also try leaving the front usb slots unplugged. I was suspecting that it may be an intermitant motherboard fault. If i have no joy then i will go and get a brand new upto date system as this one is now a bit dated though i hate throwing out working stuff. Cheers everyone.

This suggestion is almost certainly useless to you, because the fault is intermittent, but it does have the beauty of simplicity. It is rather like the routine of disconnecting the motherboard battery, but much less fuss.

So: switch off at the wall.

Press and hold the reboot switch for 10 seconds.

Switch on at the wall and then the computer.

Thanks, i will give that a try. Though since writing the original post a couple of days ago it has not played up after giving a few days of grief.
