Hello,

Somehow one of the accounts on this laptop is gone, it use to pop up after boot with the other user accounts but does not do so anymore. In the users folder, the other two accounts are their and their is another called 'NULL' and has nothing inside of it, file size 0.

I attempted to restore to an earlier point, but it still is not there.

Laptop is a windows 7 home premium hp pavillion g7 laptop 64 bit

Help would be really appreciated.

You did not say the system shuts off suddenly. That can cause drive corruption and mess up Windows, shutting off improperly is not good for the hard drive. That is a major issue, not something you want to ignore. Check temperatures of the...

Could be a virus, could be someone was playing around with the system and deleted files, changed permissions, something.

Did you do a full virus scan? Using a rescue boot disk may be a good idea, Avira Antivir has one, so do most other anti virus vendors.

I am currently trying several different types of virus scans. I used malwarebytes and spybot, but I think the laptop still has a virus because I cannot get on the internet for some reason. Also when I try to use the standard disk cleaning software the laptop shuts it self off...

It also gets hot really quick and also seems to be shutting it self off when it gets to a certain temp. I tried speed fan but no fans were detected that could be controlled. The fan is working though on the laptop.

Whether the outside of the case is hot isn't the issue. It's the internal temps that matter. Try something like speedfan to double check your temps. Also if your processor did an emergency off do to high heats whilst your drive was in the middle of writing to your user profile this could have corrupted the data. You'll have to try a data recovery program to try to restore it but not unless you are sure you don't have a heat problem. Another possibility is a failing psu.

That is a major issue, not something you want to ignore. Check temperatures of the system (HWMonitor works well), make sure CPU stays under 90 C, past that it's reaching the thermal throttling point. Even at 90 it's a bit too hot, 80 or so is better for a fully loaded laptop CPU.
