right, so you and your friend ran avast update, it froze during the update, then you restarted it, to a blackscreen?, then you took out the ram, and re-installed it, then re-installed windows, was it working ok at this stage? if avast was in the process of removing old updates etc as it froze it may has lost some core windows files, however re-installing windows would normally correct this, if you turn it on, is a blank screen straight away or does it boot up first?

Well, I reinstalled windows and now the screen just goes blank after a while. Once in a while I get blue screen error and it goes away. I am more of thinking about that a virus infected the memory. It is very random. Sometimes laptop works fine for hours before the screen goes blank so. I would change the memory and try because everytime I remove the RAM and put back in, the computer screen does not go blank for a while. It is just confusing and that is all. Anyways, thanks for the reply, I would try changing the memory.

if you had something like this;

you could plug in your friends hard disk into your computer as a usb device then run a virus scan, scan disk, and defrag etc.
something like system machanic 6 will also sort out any ram problems you have.

Well, I did installed a new hard drive and try to install windows earlier and half of the way when it copied the files it just stops. Then I had to remove the memory and put back again to continue the installation. So I am not really thinking that it is the hard drive because the same freezing up problem during the install occurred until I remove the RAM and put it back in. That is why I think it is not the hard drive. Thank you for concern again. I also plug the laptop in to a different monitor and same thing happened after a while. So it is not the hard drive, it is not the monitor and it is not the processor because when I run scan disk processor is working 100% and should freez up at that time and it never did. :rolleyes: So :rolleyes: :rolleyes: :rolleyes: :rolleyes: right now I am going to get a memory and see what the problem is.
The question that needs to be answered is what makes removing the memory and put it back in does not make the screen goes blank while I am in the windows? :eek: :eek: :eek: :eek: :eek: :eek:

you say you put laptop onto a different monitor, are you using an external monitor with this laptop? if so try it on the laptops screen rather than an external one, this tends to put an awful lot of strain on the laptop otherwise, i have a very new laptop even that has trouble on an external monitor or projector some times.

you are proberly right scott, taking the ram out every couple of mins wont do it much good, and the last thing you want is a static build up, that could turn all this into a major headache.
