Every time I start up my compaq. My windows wont start up. it says that its still loading. and i let it load for a couple of hours and its still in the same stop. It also says that there is something wrong with my OPS. I think that it wants me to reload my windows but i dont have a disc and it would have to cost me to my a new windows. is there any other way of fixing it instead of reloading windows?

Do you have the installation disks that came with that computer?

It sounds like you have a faulty video driver.
Try hitting F8 after the initial DOS screens. Select Safe Mode when the options screen comes up. If the unit boots; reinstall the drivers from the Compaq Installation Disks.

If you still have trouble call Tech support at Compaq. They have people waiting to help with this very issue.

try booting up with the install disk or download these xp bootdisks from: http://freepctech.com/pc/002/files010.shtml

its the actualy winxp pro setup disk's

your gonna want to get into the recovery console then do:
chkdsk
