Custom Build Pc Random Shutdown and No video at times

[Skillachi]

Hello to all,

Today I wish for some help with a problem I'am having with a costume build system which was ship to the client from Canada. I'am having random shut down and random videos lost from a custom build pc. So far I've removed every part from the system except the motherboard and power supply but the problem persist.

I'am also getting this message as follow

------Warning: System Boot Fail------
your system maybe overclock fail or POST interrupted. Please enter setup to load default and reboot again.

I've try that but the problem persist.

System specs:

OS- Windows xp Pro
Power supple 800 watts
500GB HD
Proccesor: AMD Phenom 9550 Quad-Core
8GB RAM
DvD drive
Media card reader

Note: I've also notice that the cpu Fan is running at 600RPM and the system is saying warning when I went into the bios.

Does it randomly reboot in Safe Mode or running from a boot disk?

Has the computer been overclocked?

Have you changed the CMOS battery?

I'd first try clearing the CMOS to factory defaults and change the battery. If that doesn't help try using a good power supply.

I am going to guess this is an Asus motherboard, is that right ?

It could be the PSU. If you have a multimeter or PSU tester I would check the voltages to be safe.

Personally though I would lean more towards an issue with the motherboard.

- Change the CMOS battery
- Check for BIOS updates

I am going to guess this is an Asus motherboard, is that right ?

I'm genuinely curious as to how you came to this conclusion.

OS- Windows xp Pro

thats your problem right there, lol just kidding

From what you say you have isolated the problem to the motherboard or power supply. So, just test with a spare power supply and you will know which component is faulty!

Yep you're right on point its an ASUS motherboard...

ASUS M2A-VM motherboard

Here is a link to the manual http://dlcdnet.asus.com/pub/ASUS/mb/socketAM2/M2A-VM/e3088_m2a-vm.pdf

hi

1.load default bios settings.
2.check the boot order in bios(1cdrom,2hdd)
3.check your hard disk for bad sectors.
4.check the psu.
5.try restore mbr of the hard disk
6.check the cooling sistem of the processor.

hi

and check the capacitors on the motherboard to see if one of them is bad.

already check, no bad capacitors as I look at the Motherboard thoroughly.

I Change CMOS battery but problem persist.

I believe the person who build it did over clock it, because I did see a message about overclocking stating to load default settings. Which I did but same problems.

I cleared the CMOS using the jumper settings on the motherboard but problems persist.

I change the power supply with no positive results.

I've come to the conclusion that its a bad motherboard. I literally replace every part in the system except the motherboard.


I've got this new message saying... (after trying to clear the CMOS)

BIOS ROM checksum error
Detecting IDE ATAPI device
Detecting floppy drive a media
Drive a error.....
Insert system disk and press enter_

hi

try to boot the pc on a live cd.

Copied and pasted, because I'm not re writing this a million times.

When you have a hardware issue, you start with the bare essentials and work your way up from there.

The bare essentials are:

Power supply
motherboard
processor (and heatsink with fan of course)
memory (1 stick installed in the lowest slot, they are usually numbered)

That's it. No mouse, no keyboard, no dvd drive, no add on video (unless your board doesn't have integrated video), nothing else.

If you do have an add on video card (because there is no built in video) then try another if the above fails.

If it doesn't boot with the memory in the lowest available slot, try each and every slot with just one stick. If there were two or more sticks, try another stick in each and every slot (by itself). Chances are more then one stick didn't go bad. One stick failing (or one memory slot failing) are not unusual, but multiples of either are unusal.

CPU's rarely fail.

My suggestions beyond that are if you get the system booting into the bios without issues consistently, go into bios and load default settings. Then disable the floppy drive (A if it's still enabled as it looks like there is no floppy drive in the system.

Ensure boot order has the DVD drive first, then the hard drive second.

Then shut the system down and connect a NEW hard drive with a freshly loaded operating system. Install windows 7 and don't put in a key. You don't need to activate the system, just check to see it's working properly.

A live operating system isn't a good test for failing hardware. So booting a live OS from a DVD isn't a good tool in this case.

I'll also add the following:

1) Visual checks for bad caps are not always going to be fully accurate. Caps can go bad without swelling or leaking. You need to check their ESR (equivalent series resistance) with an ESR meter.

2) One of those cheapo PSU testers are not worth a darn in detecting about 50% or more of the PSU's that are actually bad. Why? Because they don't test the power supply under a load AND those LED's will light within a range of voltages. Sometimes too big of a range.

Lol, I was going to ask the same thing. When I build my personal machines, I almost always use Asus boards, and I've had this happen on occasions. The last time, it turned out to be an obscure incompatibility between the board and the Antec Smart Power PSU. I kept getting "system failed CPU test" and "system failed due to CPU overclocking" messages from that annoying synthesized voice-enable Bios error reporting feature at boot. Switched out the PSU, and everything was fine.
