How do you fix the 'blue screen of death'?

i sure the best way to do it after try 100 of ways is to just start in save mode ans just go to system restore point and restore your system to the point when the system is not crash or infected. for example if you have blue screen on 6 may , you just restore your system to 3 may. it will 100percent work.

This is so disjointed. I was having a hard time finding specific steps to take when my system showed the Blue Screen of Death error message. What a message! Anyway, not sure if I can mention this here...but, after a thorough Web search with answers like this one I almost gave up fixing it myself. Before taking it to the shop, I went ahead and spent about 30 bucks to use the PC Healthboost registry cleaner...only because they had high ratings and really good reviews. Well, here I am to tell the tale. It was so easy, I now put it on autoschedule and it fixes problems as they occur. Sure hope it's okay to pass this info along. Sure saved me a lot of time, trouble and headaches.

Do I have a virus my computer mouse keeps going all over the place on its own?

additional facts :

- recently my computer mouse has been going EVERYWHERE, clicking on things in the start up menu, closing things such as my internet browser all on its own! I have a windows XP desktop. And I even went out and bought a new mouse! and its still doing it! Sometimes when it does it, I shut off my computer screen and it stops, but still I'm annoyed with turning off my computer screen every 4 minutes or so!

Answer: This kind of thing could be caused by a Virus, someone else playing a practical joke by plugging in a second mouse to your PC, or someone hacking into your PC from the internet or a local network. Turning off your monitor will have no effect on the behaviour of the mouse, it would only stop you seeing what it's doing.

You need to establish whether this phenomenon occurs when you are not on a network. If you disconnect your PC from the network and this continues, it would either be an additional mouse being used by another person, or a virus.

If disconnecting your PC from the network makes this stop, then it was someone hacking into your PC and you need to get a firewall, a decent antivirus program, and an anti-malware program immediately. Actually, you should have all 3 of those things anyway.

What system is the father of almost all modern multiuser systems?

There is no correct answer without qualifying which multiuser systems are being discussed. All modern operating systems have inherited traits and abilities from other older multiuser systems. There are multiple multiuser operating systems currently in use. IBM has their mainframe system (Z/os) as well as IBM i, both multiuser systems are unique from each other and from other systems. IBM also has AIX, a descendant of unix. Current unix systems go back to the original proprietary AT&T unix implementation in the 1970's and 1960's. Unix itself was modeled after a multiuser system called Multics. Linux was modeled after unix but written independently of it. Microsoft Windows NT was designed by Dave Cutler who brought his experience in developing OpenVMS with him. All other Microsoft Window implementations follow from that.

How do you get rid of the white foam that keeps coming back if you have bought and used two bottles of foam out and it still comes back and is there anything else you can use?

Clean your filter properly and you will not get foam. Defoamers just add phosphates adding to the foaming problem. Foaming in the pool can because by several different things. It could be chemical or equipment. First Equipment. Make sure you do not have an air leak on the suction side of the pump. Prime suspect here is the strainer lid gasket or "O" ring. Or possibly where the pipe or hose connects to the strainer of the pump. If you have an above ground pool the hose between the skimmer and the pump can be a suspect as well. The reason this is a problem is it will inject air back into the pool which agitates the water and can cause foam depending on what it going on with the water. Also make sure the return jets are pointed down. You do not want the return water to break the surface of the pool water. This can cause the same agitation and foam. Second chemical. If you have used an algaecide that is a quaternary ammonium compound this product is a foaming agent by its nature. If you use any algaecide make sure it says on the bottle non-foaming. The foam will fade as time goes on through dilution. The other chemical problem is low calcium hardness. Depending on the type of pool surface you should maintain a minimum calcium hardness level of 170 to 225 parts per million. Soft water will help the water foam up. Have your water professionally analyzed. Enjoy your pool!

Is eczema a virus?

Many professional people believe that eczema is associated with dry skin, allergens, stress, etc. However, as a sufferer, I personally believe that it is caused by a virus, most probably transported via insects or flies. I'm sure mine was started right after a mosquito bite on my calf. You cannot kill the virus with those ointments, but only help to soothe the symptoms. They come back when you stop using the ointments, because the virus is still there. It can also have a relation with the liver.
