I tried to overclock it

Personally I never over clock my cpu it makes it run way to hot and lessons the lifespan greatly if you want more speed in your laptop get more RAM first I bet you will solve your slow pc concerns without PC damage.

That would be on another WD2500JB Caviar harddrive

Either that, or start looking on the internet posting -
WD2500JB PCB Board, and see what search hits come up.

Here,.....let me try.............

Before you replace it, let me ask........
1) Was it in a Desktop PC?

2) Was it in an external harddrive?

External harddrive?
Then suggest you obtain a 3.5 IDE (PATA) external enclosure,

In an external harddrive there is a small interface circuit board.

The Harddrive plugs into the small interface circuit board, and the USB cable is attached to the small interface circuit board.

It is this small interface circuit board that usually goes bad.

The external enclosure is just like the case of the external harddrive.
Has a USB cable going to a small interface circuit board, and the harddrive plugs into it.

Disk-drives either have an EIDE interface or a SATA interface.
The largest EIDE disk-drive is 500 Gbytes.
SATA disk-drives can be much larger.

Check the manufacturer's web-site: http://support.dell.com
and select your model-number, and read the "specifications",
to determine whether you have an EIDE or a SATA disk-drive.

All Asus P5GC-MX/1333 mobos are "X-series" boards.  

If you put higher speed ram on that mobo, it will just run the ram at lower speeds.

The board will not take 1333 speed DDR3, because it is only DDR2 compatible.

OVerclocking is complicated and risky, here is neither the place to teach or learn overclocking.

Some newer core 2 chips will automatically overclock, when all but 1 core is in hibernation (which will never happen if you are using vista). Other than that overclocking involves setting the bios to increase the memory buss speed, as well as slightly increasing the cpu and ram voltages as needed for stability. There is a great risk associated with manually overclocking and adjusting voltages, and should not be attempted by beginners on machines they value.

Overclocking is set from the BIOS configuration. Not all BIOS allows overclocking, it may need a BIOS upgrade.
Check the ASUS WEB site for your model motherboard.
Overclocking the CPU (ie running at a higher clock speed) and increasing Frontside bus speed will give better performance BUT there is a downside too, if you overclock too high you could overheat the CPU and it could fail.

no need it will definitely work on windows 7. because it has xp mode that run all the xp compatible applications in windows 7. u know that windows 7 is really amzing.....

Most motherboards have settings that allow the board to try and overclock itself upon bootup. Take a look in your manual and it should lead you to the correct setting in the bios that will allow you to have the computer boot up in normal mode. Failing that, you may have to force the motherboard back to the default setup. There is a jumper you would have to move, then you would remove the battery from the motherboard. Check your manual for how to clear the CMOS settings if you need to do that step.

I do not condone overclocking!

You can try upgrading your bios to the latest version. It may let you change the CPU settings.

Intel boards are usually "locked" (BIOS), and are difficult if not impossible to overclock.

I DO NOT CONDONE OVERCLOCKING. IT CAN RUIN,TRASH, BREAK FOREVER, MAKE CEASE TO FUNCTION, if something goes wrong, not yelling at you just want to make sure you know what you are trying toget into.
But...They do sell boards designed for that purpose, I think you can get the board you have w/CPU for under $100. Look for a different board if you are serious about it.

the problem sounds like you either lost the IDE channels on the MOBO or the chipset was updated with corrupt files.

run everest home and see if there are current updates for the northbridge chipset. if you have 2 ide channels on the board switch the primary and secondary ribbons and see if the hard drives are there. if your cdrom's are ide and after switching ribbon cables they disappear and the hard drives reappear your mobo lost an ide channel, you would need to replace the board.

JAAh,

I have the same motherboard and did a little reading. The chipset on these motherboards was not really designed for the 800MHz, but it was still used by ASUS anyways. I have reduced the FSB speed on my system for increased stability. Here is the posting from another site which I found.

The 845PE Northbridge was designed for FSB400/FSB533 processors,using DDR266/DDR333 memory. (See page 11 in the Intel spec.)

http://developer.intel.com/design/ch...s/25192401.pdf

No matter how many different models of this motherboard that
Asus made, it is still based on the 845PE. Operation at FSB800
with DDR400 memory constitutes overclocking, and overclocking
comes with no guarantees (only Intel can test the chips and
bin them for speed, and the chips are not tested at FSB800/DDR400, so Asus has no way of knowing how far they can be pushed).

I've read descriptions of other people's luck with the 845PE
and it is described as "I can set the clock to 200MHz and
not a stitch more". That means even in the best case, there is
absolutely no margin left. The fact that your board runs stable
at 190MHz, instead of 200MHz, should not be a surprise, as Intel only has to guarantee the chips work at 133MHz (for FSB533).

The sin being committed here, is the user manual should state
that "overclocking comes with no guarantees". Persons interested in buying FSB800 processors, should be buying a P4P800/P4C800 or equivalent board, as the Northbridge chips on boards like that are guaranteed by Intel to run at FSB800.

If you want rock solid operation, pair a 3.06/FSB533/512K
Northwood processor with the 845PE Northbridge.
