| 163010 | 2003-07-27 10:06:00 | Thanks skinnerjack, already done that. I'll just have to get another board down & hope it's the problem. I'm actually a techy by trade so know most problems & how to fix 'em but this one has stumped me mainly because the problem is so persistent & the same scenario everytime. (You'd think that would make it easier to track down) Thanks |

| 163011 | 2003-07-28 06:27:00 | If you do find the prob i would be interested to know, its a great feeling to tweak something and have it work, but there's always THAT ONE that provides a challenge. PS Could the buzzing be from a wire resting on the CPU fan blades? |

| 163012 | 2003-07-28 06:30:00 | just had a thought, just removing the battery and replacing it, sometimes doesnt change the BIOS, remove the battery overnight and use the 'clear cmos' jumper before replacing the battery. Stabs in the dark now! |

| 163013 | 2003-07-28 08:51:00 | It's the bootblock error message that's a little puzzling. Does the m/b manual talk about a bootblock jumper? If so check that it is firmly in place, and in the disable position. If all else fails try re-flashing the BIOS, you have nothing to lose :) Good luck |

| 163014 | 2003-07-28 09:19:00 | Thanks guys, Not a wire on the fan. You know the comp isn't going to boot as soon as the buzzing starts up. If there is no buzzing the machine starts up fine. Already put a new battery in it & had left it out for a couple of hours It reset the BIOS & booted fine but when I tried rebooting buzzzzzzzzzzzzzz!!!!!!!!! I thought about reflashing the BIOS, but if I balls it up I won't get a replacement so back it goes I guess. Thanks again. |

| 163015 | 2003-07-28 11:45:00 | Last time I had this problem preceded by a buzz, it turned out to be the hard drive itself, dying a slow and noisy death ... the symptoms were much the same as yours ... an intermittent CMOS error after the buzz meant no go for the system ... Also, with the BIOS error ... it might pay to track down a manual for your motherboard based on the BIOS ID String ... I have met a couple of machines made with re-conditioned motherboards where the BIOS chips have been replaced with non-original (& incompatible) chips ... this resulted in constant BIOS AND hard drive probs ... For example, I replaced the power box & hard drive for a work mate due to bootup & Win OS issues ... everything was fine for a couple of runs then back to square one with his probs ... at the end of the day, it turns out the machine was a rebuilt oldie where the techies had cannibalised bits and pieces from a variety of machines and resold them ... they had taken a BIOS chip from one old motherboard and put it on to his ... I only discovered it when I fed his BIOS ID string into the Google search engine and found what shall have been the manual for his motherboard - except it didn't match up ... Hope this gives you ideas ... BTW what's the year of manufacture of your motherboard? |

| 163016 | 2003-07-28 12:11:00 | Thanks Rosz, I was wondering myself if I should try another hard drive, but once the machine is going it runs perfectly & scandisk shows no problems. Might try another one just to discount it (or otherwise) M/bd is GIGABYTE GA-ST800 manufactured 2002 |

| 163017 | 2003-07-29 03:02:00 | The Bios ROM Checksum error really means trouble. It's not the BIOS settings (which have their own checksum as a consistency check). Its the checksum on the actual "permanent" code of the BIOS. The fact that it's intermittent might mean that it's not "properly" burned. EPROMs were tricky, and most programmers gave short programming pulses to each location, reading after each one. When the returned value was right, they gave a few more zaps to make sure. :D Flash EEPROMs are often tested after programming at a range of supply voltages. This might point to a problem other than a flakey ROM chip. If your power supply is asserting Power OK too soon, the processor, and the ROM will be running at lower than the proper voltage. If you are starting at 3.3V, you haven't got much margin. :D The first operation will be the calculation of the checksum ... and by the time it decides that it's wrong, the volts could be right, so you don't get the bad spelling in the error message whch would be a "clue". |

| 163019 | 2006-09-13 08:36:00 | Hi, Can anybody help here please. 1 month old computer 2.4GHz intel Gigabyte m/board 512Mb DDR For the last week it has not been booting properly. From cold boot in the morning, no problem. But if it is shutdown & restarted within an hour or just restarted after installing anything I get the following message at reboot. I get a buzzing noise then this appears onscreen Award BootBlock BIOS v1.0 BIOS ROM Checksum error Detecting Floppy drive A media INSERT SYSTEM DISK AND PRESS ENTER Almost seems like the BIOS has forgotten where the hard drive is. If the system is left off for over an hour, no whining noise & it boots ok, but sometimes says CPU is not detected properly but it boots & goes ok. I've replaced the battery, & done all the usual. Any ideas Thanks BIOS ROM Checksum error |
