PC Doesn't Like To Boot
I have a PC with an ECS K7S5A mobo, and an Enermax 430w PSU. When I first
power-up the unit, it hangs after the BIOS check, right before it loads the OS. It seems that when it heats up, it will reboot more consistently. I have reseated the memory and video card. Should I have the PSU checked? I am running out of ideas for things to try. |

The screen just goes blank. Is there a clue here somewhere? I |

Have you tried jumpering the onboard 2-pin header to clear the CMOS?
Have you removed all daughtercards except the video card? BIOS on another daughtercard might clear the screen (which is why it goes blank) but not be loading correctly. For example, I have an Adaptec SCSI host controller card which clears the screen and then paints its BIOS version and devices found. I used to have a Promise Ultra100 card which did not clear the screen (which results in painting over other prior output) and in a later BIOS update it would clear the screen. Could be some daughtercard is hanging after the POST. Have you tried removing all but one memory stick? And with only one memory stick, have you tried switching to a different one (if you have more than one stick)? Do you even see the BIOS screen at bootup (i.e., does the video card's BIOS load so it can then show the startup screen, like the BIOS version, results of drive search in BIOS, etc.)? -- __________________________________________________ Post replies to newsgroup.

Sounds like either the power supply, or more likely, the motherboard has a
fault in it. -- DaveW "Buck Turgidson" wrote in message s.com... I have a PC with an ECS K7S5A mobo, and an Enermax 430w PSU.
