Windows 7: computer sometimes starts up

I have a Toshiba satellite L755-S5112 running Windows 7. Sometimes it won't boot up at all and sometimes it gets to the "Welcome" screen and stops there. And sometimes it does bootup.

If I do get it to boot up it is very very slow. I tried to run my antivirus and it started up and then quit. I ran malwarebites and it found "Trojan.happili" which I removed.

Is there a partition on this computer that I can reinstall Windows from? And will my data be safe?

I do have a cable that I should be able to connect to the hard drive and see on my other computer so that I could save the data.



What say you?

If you upload a snip of your Disk Management, it will allow us to see how things are setup. Screenshots and Files - Upload and Post in Seven Forums

Yes you should have a recovery partition and yes you can hook it up to another pc.

Have you tried running a startup repair ?

Startup Repair

If you run system recovery you will loose your data.

Consider the Clean Reinstall if this is the original bloated factory pre-install which no tech enthusiasts woudl run.

You may still be infected .... Please do the following:

Copy and paste these lines in Note pad.

@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0

Save as flush.bat to your desktop.
Double click on the flush.bat file to run it.Vista and Windows 7... right click the .bat file and choose to run as Administrator. Your computer will reboot itself.

Next, download TFC by Old Timer TFC - Temp File Cleaner by OldTimer - Geeks to Go Forums and save it to your desktop.
Save any unsaved work. TFC will close ALL open programs including your browser!
Double-click on TFC.exe to run it. If you are using Vista/Windows 7 right-click on the file and choose Run As Administrator.
Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.

Now, download DDS from one of these links:
DDS.com
DDS.pif

• Disable any script blocking protection
• Double click the dds icon to run the tool.
• When done, DDS will open two (2) logs:
  1. DDS.txt
  2. Attach.txt <--- will be minimized in the task tray
• Save both reports to your desktop.

Include the contents of both logs in your next post.

Here's the Disk mgt screenshot, I think

You have no System flag which shows where the boot files are installed and booting Windows 7 from. This is rare and a concern.

Try running Startup Repair - Run up to 3 Separate Times which will repair or rewrite the files and any other problems with boot if necessary.

Otherwise it looks like a factory preinstall, which is a corrupt Windows 7 to begin with given all of the bloatware which throttles the OS's native performance. Have you looked over the steps to get the superior Clean Reinstall - Factory OEM Windows 7?

At the minimum I'd Clean Up Factory Bloatware

Going to try Startup Repair. Can I do that in SafeMode? Runs and starts up normal in Safemode. Stalls out trying to startup regularly.

Startup Repair is run from System Recovery Options. I would use the installation DVD or System Repair Disc. Run it several times with reboots to see if it finds anything to repair.

Besides this there are many steps and tutorials provided so work through them and report back results.

I have backed up the data. I'm checking to see if there is a disk. This is a friends computer.

So Safe mode is out, if I understand.
