I have had no problems at all with my computer in the year and a half that I have owned it. I have not had to update drivers because I do not use any new software. I do not intend to try to keep up with the joneses because I did that for 12 years as a computer tech and builder. However, I was having problems with some clients getting viruses in spite of Norton AV so upon the hearty recommendation of our internet provider, I switched to our free security suite from our internet provider- who provides it for us for free. I installed it in the end of March after removing NAV. No problems until about two weeks ago when a bizarre warning happened and outlook express froze. It said that the Administrator would not allow me to use that program. Well, I am the administrator and no one else uses the system- it is passworded. I began to have trouble with not being able to access a business web site where I have done business for several years. It would not let me access. Then my outlook express was getting ridiculous. I called our internet provider who insisted that Windows XP firewall was good enough and urged me to remove the entire suite. I did so and just put in the Antivirus (computer associates is the company that did the suite and anitivirus) Then I began to have a bizarre problem- whenever I open Outlook Express, my video gets full of extra vertical short lines- it is like looking through a screen door. It can continue for up to 6 minutes and then corrects itself. This would happen the entire time I had on outlook express, but when I closed it, the problem would correct itself. Once I opened OE, it started again. I de-installed the video drivers and windows put in an older driver than the one that I had installed. It wasbetter, but the problem still happened from a cold boot when I would open OE. Once it shut off, however, it usually stayed off through the session. I have cleaned out my system with everything known to computers, just about and I have scanned for viruses and spyware until there is nothing left at all in my system. I have cleaned out caches and temp files until they are wiped out. I have defraged and swept my system until I am blue in the face. Today I put the later video driver back in the system and it all started over again, the severe video problems etc. Now, I have NEVER had a problem like this before and the ONLY new thing that I did was take NAV out and put in the CA security suite with Pest PAtrol Anti Spam EZ Firewall, And their AV I do not know if a stupid security patch from windows for OE did this or what, but I am at my wits end. I jsut want my computer back, and if I were to reformat, the updates would just take me back here anyway, and quite frankly I do not think it will solve the problem. Here are my specs OS- XP RAM 1.5GB Video Radeon 9550 256RAM Sound Audigy DVD ROM CDROM I did not build this system, it is E machines T3256. There is no information from the manufacturer either. I am on the verge of losing it completely after working constantly on this for over a week. Can anyone help me? I have built systems and worked on them for years, but I just do not have the time to do much more with this, I just need some insights. Thank you. If anyone out there can offer solid help to solve this (without reformatting) I would be forever grateful.
