This is a laptop?
Im not sure how to clear a CMOS on a laptop
I heard take out the battery and hold power for few seconds?
anyway, the worst case you have a hard drive going bad or memory going bad
but most likely its just windows needs to be repaired
can you try to do a full reformat?
you have no USB things plugged in when you are starting up, correct? no CD/DVDs either
and you should also clean the heatsink and fans while you are at it if you have not
also make sure bootup is set to dvd drive first, you can try to run repair again first instead as well
if this still doesnt work we want to run a memory test
when you start up windows7, if the memory test screen comes up go ahead and run it
Yes it is a laptop. And what is CMOS? And should I take the battery out and hold power? Or what should I do first? And yes no USBs devices are connected (except the mouse, but I guess I should unplug that too). And what do you mean by setting DVD drive first then run repair again?
