I cant install and os still. tried different monitors but its not the monitor. i tried a different hard drive. please please help. i have a laptop which im using now, but desperately need this one to work. sad part is im a computer tech and can't figure this thing out.Welcome to the CH forums.

As a computer tech how would you respond to a potential customer who gave the same details you have given us :-?  Would you not want to know what make of pc it is and what model and what Operating System and what hardware is installed etc.. :-?

"Cannot FIND Ntldr" is a well documented problem with XP so will assume that's the O.S.

Need to know if you are using a genuine full XP cd or an upgrade version.  Need to know if you are trying to do a clean install or a repair and what file system is being used and if the hard drive is partitioned and if you can afford to lose all data on the existing hard drive.  Having reset bios to default values have you modified the boot sequence to boot from the cd first :-?

Have you run hdd manufacturers diagnostics :-?

Please read the very first post on this forum from CH Admin..

ThanksYou're absolutely right...so here are the specifics. I was doing a clean install on the computer. The file system was ntfs. I don't care about losing information AT ALL. I REMOVED the battery to reset bios. Didn't work. The computer is a compaq presario 7360. Yes it's an older model lol. The install never completed so technically speaking there isn't a os installed yet. Yes the boot sequence is set to boot from cd, this is how I began in the first place. Yes, it's a genuwine xp disk. I have also tried, 2000 pro, server, and advanced server just to see. Nothing will install. I can not boot from a FLOPPY. Wanted to run fdisk, but can not even do that. Again please any help will do and don't worry about me losing info..i could care less long as i get this sucker up and running. lol . tx in advanced.Google memtest86.Yep, sounds like a hardware related problem.  Can you remove/replace ramsticks one at a time rebooting after replacing each ramstick :-?

You say you can not boot from a floppy, does this mean you cannot use the floppy drive or that a bootdisk will not perform :-?

Tx, I'm almost positive it's a hardware issue. I have tried removing each ram stick and rebooting to see but still the same problem. I've never experienced anything like this before. The green screen is not even actually completely green. It's more like dot pitch green cuz I can see the red compaq sign behiind it, and like the white memory count at the top of the screen, but that's it. Why it turns green after booting I don't know. Also my floppy drive just isn't working, but that's not a problem.It might be. I would suggest INSTALLING a floppy that is known to work and see if you can boot a WIN98 boot disk. Or a disk fromt he appropriate hard drive maker's site. It would be diagnostic to know if it is even trying to read a boot device.

Can you navigate in the BIOS (F10 at boot)?

I believe one that I recently worked on of that same model had a K62-350 processor which dates it pretty well. It may just be shot.
