Maybe you didn't install your CPU probably. Remove it and install it again ~Death-Knight~

sounds like it MAY be a dead bios chip. I had a very similar exp before. Had my bios chip re programmed and all was ok again!!! Have you been trying to upgrade the bios or is it a new M/B

its a brand new motherboard and the cpu was installed fine and i tried different ram and still nothing

any other ideas? it has to be the motherboard or cpu thats my best guess

Huh? that was not my complete post; it showed my complete post on the confirm here page, but it showed this incomplete post on the success page, luckily it contains the relevant info from the end! now comes the complete post again (luckily I saved with notepad...): I've got that problem too; I've searched with google for an answer but didn't find one, only others having the same problem; I'm listing these places here. I'm also listing some keywords for search engines. If anyone comes across a solution or other info regarding this problem, please post it here or a link to it; thanks! Problem description: After powering on the PC, the monitor starts briefly and then switches to Standby. The PC tries then constantly to access the DVD Rome drive. No graphics-card BIOS message, like usually, appears but the monitor switches directly again to Standby. A Mainboard BIOS message does neither appear; this would anyway only have come after the graphics card BIOS message. This occurs also sometimes after a Windows restart: the monitor switching to Standby instead of the graphics card BIOS message appearing and the PC tries constantly to access the DVD Rome drive. This problem arose already with January's or February's 2002 BIOS. Possibly it arose the first time, after the on-board sound was deactivated the first time in order to install a soundcard. The soundcard had not been installed however, when this problem arose. The problem arose the first time approx. 1 month ago, that was the 11th month since assembling the PC, so 10 months without problem. Unfortunately I do not have connected the PC loudspeaker, because the PC loudspeaker plug (2 pins) does fit the Main board (4 pins) connector. I had however connected the PC loudspeaker plug to the PC speaker input of the soundcard, but there were no sound to hear. If this problem arises, no RESET helps, only a physical power off works. It then needs 1 to 5 of such turning on attempts for the PC to boot; then there are however no further problems. Also this problem does not arise each time turning on the PC. A sidenote is perhaps that only if this problem arises, very frequently Windows 98 SE after first time displaying the Desktop background before icons are shown, takes a approx. 5 seconds "break". Also: If the problem is not there, the DVD drive is accessed only once and then one hears the hdd accessing slightly longer (~0.5 seconds) and then the BIOS messages are displayed. So perhaps it's a recognition problem with one of the drives. But if the problem occurs, there might (i'm not sure) also be a sound like access of the hdd (only about ~0.1 seconds then) but then it's just the DVD which is (tried to) accessed as described above. So the drives might not be the cause afterall. [partly using googles language translator] What I am interested in: Could someone try to enable onboard sound and look whether the problem vanishes? I don't want to, beacuse I had problems with that when i first installed Windows and therfore don't want to risk anything (if you have to install a SiS driver you can disable the on-board sound in the device manager (My Computer properties) so a "real" soundcard may still work). An elitegroup support representative said that from their experience this problem is due to the power supply not being able to deliver 30 A on the 3.3 V line. My power supply only delivers 20 A on 3.3 V (300 W supply). From what I have checked being available, one would need a 480 W supply to get 30 A on 3.3 V (and that costs around 150 $ :-( ). But I can't find this info on the AMD website and I've also not seen this info on hardware websites regarding 30 A on 3.3 V. BIOS info: memory timing has always been most "aggressive", the problem occured with 100/133 (CPU/RAM) (Ami BIOS setting) with Duron 700 and PC133 SDRAM and occurs with AthlonXP 1800 (133/133) and DDRRAM; also most aggressive memory timing. System info: Mainboard: Elitegroup K7S5A SiS735 Chipset HDD: Fujitsu MPG3204AT-E DVD: Samsung SD-612F AGP slot: Hercules 3D Prophet 4500 Kyro II 32 MB noTV PCI slot 2: Hercules Gamesurround Fortissimo II Digital Edition Soundcard PCI slot 3: D-Link DFE 530TX Network Card except for the soundcard, everything has always been there.

workaround to solve message being incomplete: copy and paste your text written here in the message frame on the confirmation page after clicking submit follow up here; it then submits correctly :-)

current BIOS version is 26.06.2002 I updated from 12.01.2002

I have found interesting information here: http://www.viahardware.com/faq/kg7kr7/boot_problems.htm section: Nothing happens when I try to boot, or only fans start. What's wrong? and section: Why must I switch on and off and then on again to make the system boot? most relevant Summary: Try clearing the CMOS using the jumper on the motherboard (disconnect from the mains power first). This can solve the occasional inexplicable problem of the machine suddenly failing to boot after months of faultless operation.

Summary of further above mentioned links: "K7S5A motherboard I use is very picky about power supply's. The 400W PSU I had would turn everything on but the display, and the system wouldn't beep or post" "There is a known cold boot problem from the partnering of the 1.4TBird and K7S5A motherboard and ... . The problem is something along the lines of the K7S5A not providing enough voltage to the 1.4TBird fast enough on a cold boot ..." "If the voltage is around 1.7V to 1.75V for the 735: There never seems to be a problem. If the voltage is 1.8V to 1.85V, some (few) boards can have the problem. ... it is often only present at specific 735 chip temperatures. ... It seems to happen when the 735 is in a range of temperatures.... If it's cold, it's OK, if it's hot, it's OK. In the middle, it's no good! With the voltage too high, different boards have different temperatures that have the problem" "board will fail to boot when the soft-power (front of case) switch is pressed. ... Turn off the power supply so the motherboard isn't receiving any power at all. Wait a few seconds. ... Now switch the power supply back on. ... Now you should be able to power the system up with the soft power switch. It seems the motherboard is simply getting 'stuck' at soft power off and needs a real 'cold boot.'" "AMD techs told the people who have sorted my problem that any AMD processor which is greater than an Athlon xp2000 needs a fan which has an rpm greater than 2500" (from top to bottom of those links) other interesting information: http://www.pcguide.com/ref/mbsys/bios/bootSequence-c.html search engine text I used to find the abit doc: standby boot problem solution (with google) I haven't cleared CMOS yet; will post how it works...

Also, don't forget what Elitegroup said (it was Elitegroup Germany and they were referring to all AMD cpus in fact!), which is somewhere in the midle of the first long post: An elitegroup support representative said that from their experience this problem is due to the power supply not being able to deliver 30 A on the 3.3 V line.

for info: how to get links to work: use normal HTML tags: look at source code here or see http://www.w3.org/TR/REC-html40/cover.html#minitoc There should be (! in fact!) all you need for HTML

ah,.. I know, many posts, much text, LOOK AT POST 15 !!!

It doesn't work. :-( But I got the PC speaker to work (2 pins on to pin 1 and 4 of 4 pin plug); if the PC boots up succesfully, a PC beep occurrs just on power-on; when the problem occurs, no PC beep ocurs; so the problem seems to be right at the beginnig.

perhaps it does work, the problem arose on second power on after clearing cmos again, but now has not arisen for more time than ever before since the problem first occured; other tips: remove all dust seat everything correctly

0

a small note: the beep does not occur on power-on but after or when the graphic cards bios message has been displayed

Just because you've updated the BIOS doesn't necessarily mean that the settings are correct. If you are able to reach setings check to ensure that your system is set to use the CD or DVD ROM as the first boot device to look for. Next is the floopy drive A:\ , and then the hard drive after that. Whether its an IDE, ATA, or SCSI has no bearing on the setup that I'm aware of. Good Luck...
