49022 2002-05-15 10:59:00 mates old pc has just started a werid problem. after sitting for a few days it won't go. hardrive goes but monitor will not turn on. if you wait a wile and try again it will run normally. if you turn it off and restart it, it will also work fine. its an old k6-2 500 with an AT powersupply. thoughts at the mo is a bios battery problem or a powersupply starting to fail(needs warming up).

anyone had similer and can spill some light on this?

49023 2002-05-15 12:58:00 One of my computers is doing the exact same thing. Started about a fortnight ago. Hard drive lights up at boot, no monitor. Restart by holding the power switch in for 4secs & it boots up fine.
Athlon 900, 384mb Ram, 6 month old 300 watt power supply.

Weird.

49024 2002-05-16 05:17:00 I'd suspect the battery. As soon as you apply power, the cmos ram gets supplied from the system power. When the power goes off, it will hold up for quite a while. It should give an error message because the checksum will be wrong, but with modern video (especially modern video on the motherboard) it might not be able to display that the cmos ram is wiped if the cmos ram is wiped and it can't access the video! Once it has been powered, it will do an auto configuration.

The date will certainly be wrong if this is the case.

49025 2002-05-16 06:39:00 date seems fine which is what makes me suspect the power supply. mayby with this cold damp weather its output voltage is to low untill it warms up and the voltage increases. Guest (0)
