WinXP won't boot

[bert202]

I got up this morning, did some stuff on my computer and then decided to see if i could get more from overclocking. After changing my ram to cpu ratios and pushing up the FSB I couldn't boot. I droped everything back down to where it was before and it still wouldn't boot. I droped cpu volts and speed back to stock 2500 and it still wouldn't boot.

None of these worked:
I tried going into safemode and restarting.
I tried going into safemode and turning all start up programs off. (I had installed some new stuff a couple of days ago at a lan.

I tried doing a recovery install. After the recovery install it booted after finishing the install. I reinstalled motherboard drivers to see if i could get my network back, restarted and it wouldn't boot again.

I looked online and didn't find any updated drivers from what I had.

I did another recovery install to see if i could get back and mess with drivers again. It gave a message about the Onboard sound drivers not being Microsoft signed. I said to go ahead and install. Then the install crashed. It booted again and it went back into the install and repeated the same message about the sound stuff. this time i said not to install and it crashed again.

So now i'm in the middle of a crashed recovery install. I'm going to try to do another recovery install to fix this crashed one and see if it boots and if i can get into safemode again.

Stats:
WinXP Home - NF7 -S - XP2500 - Radeon 9800 np - Audigy2 ZS - 60Gig hd and a 200G sata hd. My installation is on the ata drive.


Any more ideas? Sorry about the long post.

Edit: forgot system stats

Did you try clearing CMOS? Since this started with BIOS tweaking, it follows that the problem is with CMOS.

I tried clearing CMOS and it got to the same point and the screen went black again but this time when i reached down and hit the power button to restart it poped up again!! the screen disapeared a few more times and i'd hit a button on the keyboard and it would come back up. I am finaly at my desktop. I am right now installing drivers. I have rebooted and so far have my graphics card installed. So far so good. I am going to flash my bios to the newest version tonight as well.
