Replacing missing or corrupt file

The install cd came with the win 7 software and i have only used it once to install it. i keep all cds for computer in sleeves in a protective container. is that what you mean? thanks.

I'm not sure then, it may just be the CD/DVD drive being weird, I have some music CD's which won't play properly on my Xbox, but will be play perfectly on a CD player.

BLUE...well i guess it was too good to be true because my pc stopped booting up without resorting to the use of the repair and/or orig install disc.So...last week i made a back up copy of what i needed from my desktop and did a clean install using my original win 7 home premium install disc. The install went smoothly so i figured it would include the missing file i have been unsuccessfully trying to replace since a longgggggg time ago.Since i completed the install and lost all of my programs etc i have only reinstalled a very few of them just wanting to concentrate on making sure my prior lost/corrupt file problem was solved.
Much to my surprise my desktop now starts up the first time some of the time and some of the time it doesnt! I continue to get a black screen on boot up which gives me three options.
1.Use a prior version of windows
2.Start windows normally....this is the one i always select
3.Use Recoverty console....this is the option i used to use which gave me the message...File: \ CMLDR ...Application is missing or corrupt. Status...OxOOOOOOf.

So i decided to start it up using the Recovery Console and sure enough I received the same error message as above .I dont understand that because i thought a clean Win 7 install would at least load my missiinng file CMLDR but apparently it didnt.

I was hoping i could totally eliminate the black screen giving me the three options listed above but that didnt happen or i dont know how to do it thinking the clean install of windows would include it..apparently not..Now i cant even get the pc to boot up the first time every time. I turn it off and restart it once or twice and for some reason it then boots up and works fine.

Do you have any suggestions at this point short of my formatting the hard drive and starting from scratch? The pc seems to have slowed down since the clean install and i have used several variations of the start up to try to speed it up without any real success.
This desktop is 4 1/2 years old and i only have 4gb of memory installed. It will handle 8gb but i dont want to spend the money for that if it really wont help it run faster.

Thanks for any help you can provide.Fortunately my HP laptop works fine and i can use Easy Transfer to reload a lot of my desktop if i do end up cleaning the hard drive.

If you have an SSD, make sure the following are up to date:

• SSD firmware
• BIOS Version
• Chipset Drivers
• Hard disk controller drivers/SATA drivers
• If you have a Marvell IDE ATA/ATAPI device, make sure the drivers are up to date from the Intel site or Marvell site and not from your motherboard/vendor support site.

Check for any file system errors and bad sectors using Option #2 of:

• Disk Check

Use this command with Disk Check:

Code:

chkdsk C: /f /r

blue..thank you. i ran a har drive utility on Hitachi site and it checked out ok. ran the dsk chk and now it seems to be booting up normally ...i shut it down and started it 3 times so maybe it is fixed. i wonder what would happen if i ran the erecovery console again which is where i get the corrupt or missing file message.I think i will leave well enough alone at this point.

Do i access the windows boot manager via the bios? i want to reduce the amount of time before it starts to open windows. i have done this before but too long ago to recall how to find it. Either way thanks very much for your help.

You want to decrease your boot time?

yes and i was able to figure it out myself and now have it down to a 3 second boot from 30 seconds. I would actually like to delete the Boot manager but am afraid to do that. thanks for your help.

Welcome, and DO NOT delete the Boot Manager, if you delete it you will have a unbootable system.

Got it. thanks again.

Welcome :)
