Not sure if I have virus or not

Specs: Windows Vista
I have spoken to some friends about my pc problems and they both helped me as well as they could, but my laptop still has problems. They both have said it sounded like I had a virus, but I ran my anti-virus and it comes up clean. I have also installed Avast and that came up clean as well. I also ran a registry cleaner. I will list the problems I have below.

1. Sometimes on boot up my laptop will start up then shut down automatically, it will happen a few times before shutting down completely.

2. If I get it to the start up window where it gives you options (press F1 for this press F2 for that, etc.) sometimes it will stay like that (have left it to see if it will continue for up to a half hour and it doesn't). Other times it will look like it will continue booting up only to give me a blue stop error page.

3. Sometimes no programs will open at all, not even task manager, for up to 15 minutes and when I have no problem opening a program up it takes forever to load.

4. About every other week, sometimes three or four times in the same week my laptop will shut itself down.

Please help, I don't know what else to do. I have also tried to do a full system restore (where it goes back to how it was when I first bought it) and because my laptop won't boot up correctly it will not let me. I will appreciate any help very much. Thanks

"1. Sometimes on boot up my laptop will start up then shut down automatically, it will happen a few times before shutting down completely."

"4. About every other week, sometimes three or four times in the same week my laptop will shut itself down."

A computer can reboot (Restart) for a no-apparent-reason-to-you if you have a software problem, but it won't normally shut down.

Most malware these days is NOT a virus - it's something else. It's possible malware could shut down the computer, but I've never heard of malware doing that these days.

Almost always, only overheating of the cpu, or a main battery problem, will shut down the computer.
If the cpu has overheated, the computer will not start up again until the cpu has cooled below a certain temperature.
If the main battery is not charged enough for whatever reason, the computer will shut down, and it will not start up again until the battery has been charged some, via the AC adapter.

"2. If I get it to the start up window where it gives you options (press F1 for this press F2 for that, etc.) sometimes it will stay like that (have left it to see if it will continue for up to a half hour and it doesn't)."

Hardware problems or driver problems can cause a long delay while booting, or even cause the boot to get "stuck" .
- an optical drive problem - if that's the case, it probably won't work properly in Windows either.
- a problem reading the ram - try re-seating the ram, with the AC adapter and the main battery removed
- a hard drive problem - test the hard drive - the ram must read properly when you test the hard drive
- a corrupted file that is a driver file, or a corrupted file related to a driver file
Sometimes you don't get the blue screen or the delay, or as much of a delay, in Safe mode, because Safe mode doesn't attempt to load the problem driver file. .
- remove any bootable disks you have in drives
- press F8 repeatedly while booting, don't hold down the key, when the boot choices menu appears, choose
Safe mode.
You will see the screen fill will lines about things that are loading, then that will stay the same for a while, then you'll get the Logon Screen or the desktop will load right away.
Answer Yes to whether you want to use Safe mode, see if you get the blue screen message.


"Other times it will look like it will continue booting up only to give me a blue stop error page."

If the blue screen message stays on the screen, what does it say?
STOP: 0X000000xx what?
If it names a file, it's often at the end of the text.
If you see that, what file name is it?

If the computer reboots before you can read the blue screen message....
- remove any bootable disks you have in drives
- press F8 repeatedly while booting, don't hold down the key, when the boot choices menu appears, choose
Disable automatic restart on system failure.

It will be disabled only until you boot the computer again.

The computer will attempt to boot normally, and if a blue message appears, it will stay on the screen.
What does it say?
STOP: 0X000000xx what?
If it names a file, it's often at the end of the text.
If you see that, what file name is it?

If you can get into Windows,

Win XP is set by default to automatically reboot when it encounters an unrecoverable error.

To have XP possibly display an error message you can investigate instead of the computer rebooting:

1. Click Start, and then right-click My Computer.
2. Click Properties.
3. Click the Advanced tab, and then click Settings under Startup and Recovery.
4. Under System failure, click on the small box beside Automatically restart to remove the checkmark.
5. Click OK, and then click OK.


"3. Sometimes no programs will open at all, not even task manager, for up to 15 minutes and when I have no problem opening a program up it takes forever to load."

- the same thing that caused the blue screen message can cause long delays in Windows

- many people have way too many startup programs loading - programs that load when Windows first loads the desktop. Some of them run only when Windows starts up - some run all the time. Some prgrams check for updates when Windows first loads - if updates are available, they're often downloaded in the background right away. That alone can cause long delays. Wait until the hard drive activity led stops blinking, or until the cursor is no longer an hourglass, before you click on something, when you first boot the computer.
Eventually you'll be able to press CTRL-ALT-DEL to pop up Task Manager, and you'll see which Process (Processes) is (are) hogging the cpu activity. Copy down the names of them, other than svchost, tell us what they are.

Tell us what the blue screen message says, and if a problem file is named, tell us what it is, and we'll go from from there.

Sounds like it's overheating. Get a can of compressed air & give a good shot of air into the cooling vents to blow out any dust.

And make sure you don't have a lot of useless garbage loading at startup. Run MSCONFIG & disable all the unnecessary startup entries:

My laptop died two days after I posted my original message, GAH. We took it to a friend who is a computer techie and his advice was that it would be cheaper to just buy a new laptop instead of fixing something that would end up having problems again. So, after many frustrated conversations my husband finally gave in and bought me a new one, lol. Thank you both for trying to help, I appreciate it. :)
