Hi,
I purchased my PC about a year and a half ago, and am now experiencing
some hardware problems. I'm hoping you can help.
System specs:
* Asus Motherboard A7N8X-E Deluxe
* AMD 3000+ (Athalon XP, not 64bit)
* 2 x 512 3200 Dual channel DIMMs
* Nvidia 256mb 5700 video card
* 80gig IDE hard drive
* Window XP sp2
* dvd burner
* Bluetooth wireless keyboard and mouse
The basic problem is that about a month ago, my pc wouldn't boot (after
power failure). Every time it got to the post report, it would either
say failed to boot because of CPU overclocking (i've NEVER overclocked)
or it would start to load the OS and the screen would go all
multicoloured and the PC would turn off. I messed around with the bios
and reset the clocking of the CPU to 1700. This allowed the PC to
boot. Every once and a while I when I reboot I have to go in and reset
to bios again to 1300, then eventually back up to 1700. Sometimes it
works, sometimes I'm stuck at 1300 for days. Sometimes it does nothing
when I try to turn it on, and I have to disconnect the power for 10
minutes, then I can get it to boot and into the bios. I have not been
able to run at 3000 since the problem first began. When I am running,
it seems to operate normally, although it is quite a bit slower than
before. Every time this happens, it is getting harder and harder to
fix.
I've verified all fans are operational (cpu, case, videocard,
powersupply), although there is a bit of noise from the CPU fan.
Perhaps it overheated at some point?
I've tried flashing the bios from 10.08 to 10.13 (latest), but that did
nothing. I also tried running with only 1 dimm, trying them both
separately in case I have a bad memory chip. No change in behaviour.
I'm fresh out of ideas, but I suspect it is the CPU. I suppose it
could also be the motherboard. It may even be the power supply.
Any Ideas?
Any help in this matter would be greatly appreciated.
If the CMOS battery is ok, I suspect your PSU may be on it's way
out. What are your voltage readings like in the BIOS? Do they
change much if running at 1300 instead of 1700? Nearly every time
I see a PC that won't start sometimes until it has been unplugged, it
turns-out to be a faulty PSU..
HTH
