Computer start up and gets to Windows logo screen and restarts!!!

PremierCisco

Hi Folks,

I have a a computer that im working on, just to give you a bit of background on it,

It running Windows XP Pro, it all started when the computer frooze while running. Restarted it and all you get is restarts and sometimes 1 long beep and one short beep.

This suggests a motherboard problem from reading up on the beep codes.

However it is using a phoenix bios version so the codes dont amtch if you know what i mean.

The PSU is running Fan also, however the CPU fan is not.

Any suggestions would be very helpful.

How would i test if the motherboard is screwed?

Regards

Eamonn

Take out all the PCI and other cards. Remove all the memory modules. Replace each memory module one at a time: first module 1 - reboot if no beeps then remove module one and install the second module - repeat as needed. Then try module one with module 2. If no beeps and system boots properly shut down and add PCI cards one at a time.

Hello Robert,

Thanks for your reply and suggestions.

Ill do that and let you know how i got on.

Again Thanks

If you cannot find a good resource to explain the mobo's specific beep codes the best thing to do is consider the causes in order of descending probability: RAM, PCI Card, mobo component/CPU.

Good luck!

Change the plug into another socket for the CPU fan to get power, just in case there's a problem with the one it's already on.
It might be a case of the CPU fan failing to cool the processor enough, so it'll shut down automatically or fail. Does the PC start up for a longer period when left alone to cool down a lot beforehand?

What make is the motherboard/PC?

You should really start simple and change out the memory. This takes less than 2 minutes. I've had the exact same problem on my personal computer many years go. After changing the memory, it worked. RMAed the sticks, got new ones, good to go.

Bad capacitor on the motherboard IMO.

If the CPU fan is not moving, I'd say that's a good place to start.

+1, although the PC shouldn't get to the Windows logo screen, I would think that any 'modern' BIOS would error out during POST.

If not this, as everyone said, remove all peripherals and extraneous devices/RAM one by one and see what happens.

I would amend my original post with a statement that the FIRST thing you should do when you have a PC with issues such as this is inspect the caps on the mobo and for any other possible signs of a physical issue. In my experience RAM is still a more likely cause but popped caps is also quite common and by taking 2 seconds to look at the motherboard, especially around the CPU, this can save a lot of time.
