I don't actually have the problem any more, because I eventually managed to fix it. But I thought it might be interesting to see if anyone can tell me how the problem might have occurred in the first place.

I don't work in the computer repair industry. But I've been interested in computers for a while now, and I generally seem to be (at least slightly) more capable with computer stuff than some of my friends are, so I occasionally end up doing the odd computer repair job for them.

Anyway, one of my friends wanted their Vista laptop upgraded to Windows 7. They gave me a setup disk and a serial number and I set about the task. The install went fine and it was up and running pretty quickly. The only problem was that it was a bit slow.

I had a look and found that it only had one gig of RAM. I researched what kind of RAM it needed, and discovered that it needed PC2-4200. But, when I took the back off, I found that it had two 512k sticks of PC5300 inside it. At the time I thought this was a bonus, because I already had two 1 gig sticks of PC5300 lying around spare. So I put in the two two 1 gig sticks of PC5300, and then the laptop wouldn't boot up. Then I put the old RAM back in again, and it still wouldn't boot up.

At this stage I could have just reinstalled Windows 7 again. But, because I thought it might be a good learning experience for me, I decided to try to fix the problem instead.

I first ran Startup Repair.

Startup Repair could not fix the problem, but it did give me this error code: StartupRepairOffline- no root cause

After a bit of Googling to find out what to do, I tried the following:

chkdsk /r (no errors found)
bootrec /RebuildBcd (this did not fix the problem)

Then, just for the hell of it, I ran:

bootrec /fixboot

And this did fix the problem.

So, what I am wondering is, how could just swapping some sticks of RAM damage the boot sector on the hard drive? :blink:
