Error Re-installing windows

I have an acer aspire 7745g laptop, 8 gb ram, intel i5 460 m @2.53 ghz, (was) running windows 7 home premium. I got a serious virus causing many BSOD's, so I decided to reinstall windows via acer erecovery discs. It runs smoothly, aks me to reboot, then when it says starting services, an error message pops up, saying that windows shut down unexpectedly or encountered an unexpected error, and could not complete the installion. Press ok to reinstall windows. So I do this, and the same message comes up. I tried reinstalling the recovery disks, but same thing. Note, this is just reinstalling windows and keep hard drive, not installing factory settings. Any help please? I do have my most important files backed up, but it would be a hassle to have to reformat everything.

I'll try it now. Hopefully it'll work. So it's a bad idea to do the same thing from the recovery disks? Are the disks just to reinstall from scratch?

I have my most important critical data backed up. I have some cool stuff on my C drive, and would be a drag to install it back, but i won't get a heartattack if I lose it, so if it erases my C drive, it erases my C drive. Should've transferred some stuff to my d drive i'm thinking, but it's too late for that now.
So what ur saying is recovery discs are only good for reinstalling everything from scratch (formatting the whole PC)?

Yeah, well, I don't have the resources to copy to external media, the old comp I'm writing on now has only 200 gb of memory, which is nearly full. I got the most important stuff off.
Anyway, I have the same error message, so looks like factory install will have to be, whatever is erased. My question: should I do it over recovery disks, or from the acer recovery partiion? If that doesn't finally fix my computer, then warranty will have to be used. Just to say, the recovery disks were made by the store before I started using my computer, so they might be the same thing.

Running full factory Recovery, from disks or by booting the partition, is always a destructive install which reimages the HD to exactly how it was when it left the factory.

Running Factory Recovery from the HD partition is more stable method. I'd only run the disks as a backup or if the HD fails. However, since the store made them for you I would take them back and tell them they don't work, so if they'll replace them you have on hand a viable backup method.

Once you get your Win7 set up and running good, also save externallly a Win7 backup image as a much better backup of your customized OS.

Finally, you are entitled to clean reinstall just the Win7 OS without the Acer factory bloatware and utilties, using the Product key on the COA sticker on machine. Here are tips to get a perfect install if you are interested in this option in the future: Reinstalling Windows 7 - Windows 7 Forums

The store ones weren't broken, same thing happened from the recovery portion hardrive. It's reinstalling to factory settings. If it doesn't work, then Acer will deal with the crap, hopefully the computer will be so f***ed up I'll get a brand new one lol (just a dream)

Are you saying that you ran the Recovery Partition from boot using the Alt + F10 hotkeys Barefoot gave you, and it failed as well? Can you describe exactly what happened?

If so, you can wipe the HD to try running the Recovery Disks, as they might work if the problem is a corrupt boot sector which will be wiped by Diskpart Clean All command. You have nothing to lose anyway now. SSD - HDD Optimize for Windows Reinstallation - Windows 7 Forums

If wiping the HD fails, I'd next test it using the maker's diangostics/repair extended CD scan: HD Diagnostic

Next I'd test the RAM using memtest86 for 5-6 passes or overnight: RAM - Test with Memtest86+ - Windows 7 Forums
