Solve : Initial boot up problem?

Answer»

Hi all,

New to the forums and need some serious help.

I had a BITSER computer made about 6 months ago by a computer shop that has recently folded and closed up........conveniently my computer has now decided to play up. My chances of warranty fix are gone.

When the machine was initially built I was having temp problems with the CPU and it came down to a motherboard fault. Motherboard was replaced and had no problems for the last 5 1/2 mths. The components as follows:

ABIT motherboard
AMD 3000+ 64 bit CPU
512 DDR RAM
160 GIG Sata HDD
NVIDIA GE Force 5600 Video Card

Problem:

Initially I when the power button was pushed I the computer would power up for 1 sec then power down for about 1 -2 secs then power up giving one beep. The computer would power up past POST and go into windows xp home.

Now I start up from the power button and I get a two tone continuous beep and the computer won't boot up. Press the reset button and it fires up giving the 1 beep and past POST into windows xp home.

All BIOS settings are at default.

I did pull the RAM tonight and there was a bit of dust on it. Cleaned it and then replaced it, same problem.

Please help with any suggestions. If more information is required I will try to advise.

Thanks in advance guys.

I just UPDATED the BIOS and on a manual power up it powered up, powered down, powered up and then one beep and into windows normally.

I have no idea.

ThanksThat's an over temperature alarm. Remove the case side and get some cold air in there via a room fan or similar to test.
Check the trigger levels in your BIOS settings.How do you get to your Bios settings?

It's not very nice to hijack someones thread.

I believe it's F10. At least it is on my computer, it might vary between F-keys on different machines. Of course press this when the BIOS is loading; before the Windows loading screen.

I went on the BIOS settings and there was nothing about trigger lvls on thereAbit motherboards come with a windows based programme that updates the BIOS with a click of the button. This was done and the new version of BIOS updated.

More info:

This morning I turned the computer on, powered up but did not pass POST. Manual reset and computer made the single beep noise again then booted up into Windows. No error message indicated.

(I have noticed when the computer boots after being turned on, a strange fan noise has appeared???)

Thanks to those that have replied. Still need more help.Hi there, problem FIXED. I thought the best place to start would be the PSU. Removed it from a 6 month old computer thinking it should still be in good condition, and I pulled out what looked to be a 1990 Pentium 1 power supply. Fitted was a 220W power supply, trying to run an ABIT motherboard with AMD 64 bit processor, two DVD drives, a harddrive an aux fan and 8 USB ports. Something about this tells me it was a problem waiting to happen. Bloody BASTARDS in the Computer shop tell me there is a 400W power supply fitted.....huh. Just goes to show you should always make sure you check what you are getting.

Anyway, $45 later and a 400W power supply fitted, computer appears to be running perfectly.

Thanks to those that replied with help.
