1197779 2011-04-27 12:21:00 The M2Npv-MX dual core PC I gave to my nephew is frustrating him by randomly not posting. The cpu fan spins briefly, then stops. With subsequent presses of the start button, the fan spins only briefly... perhaps a few seconds.
To get it to give a healthy beep, I disconnect everything in an effort to force it to error beep. Once it error beeps, then it will post after the memory etc it re-fitted. So far, eventually I've been able to revive it.
Originally it would not post if it was upset with say... a hardware change, but now it randomly fails to start more frequently and for no apparent reason.
Specs:
Asus M2Npv-MX
dual core cpu
2gb ram stick ddr2
Newest bios update which is '08 I think
Approx 4-5 year old
500gb sata hdd
XP SP3
bios battery tests@3V

Please help, thanks

1197780 2011-04-27 12:29:00 Is it still under warranty? if so take it back.

I would suspect failing motherboard if all components seem ok

1197781 2011-04-27 13:17:00 Sounds like a BIOS update I put on the other computer a few mths ago.

It must have been buggy. Because nearly every day, when I turned it on, it beeped 3 times and never started. Until I reset it 3-4 times then it beeped once. In the end I reflashed it back to the previous BIOS. And its been fine since

If the BIOS you've got is from 08 all of them are betas (1201, 1301, 5005, and the latest is 1305 from 21/9/2010), which is also beta. I would reflash it back to 1101, which isnt a beta. From 11.10.2007

Altho I would check what BIOS you need (for the CPU you've installed). Otherwise it may or may work after you reflash it to 1101. Since 1201 and 1301 have support for new CPU's

1197782 2011-04-27 13:53:00 And the BIOS I had, kept corrupting itself. Because, sometimes it would say recovering BIOS on the post screen.

Buggy BIOS'es can do strange things. This is one of them. Another thing buggy BIOS'es can do is loop / go round in circles everytime you turn the system on. It never loads windows. It keeps going back to the post screen

... 4 or 5 years old so wouldnt think so.

Speedy
...very good points. Will review and flash it.
If memory serves, it was on 0702 when I first got that PC so should flash back to any of the 4 previous. However I think it was flashed to try and solve certain problems. Anyway we will see...

Thanks.

1197785 2011-04-28 03:51:00 Dont go backwards, flash it to 1101. If yours is 0702, 1101 is 3 BIOS's up from that Speedy Gonzales (78)
1197786 2011-04-28 07:06:00 Don't sound like a bios fault to me....well its not the first thing I would be checking anyway. Sounds more like a power supply issue. Alex B (15479)
1197787 2011-04-28 07:13:00 Well if its a beta BIOS I wouldnt use it. Speedy Gonzales (78)
