3 weeks ago, my Dell Inspiron 1720 was hit with multiple infections. I took it to Staples with my Vista software and had them wipe out everything and reformat it back to scratch. I picked it up the next day, took it home, and started doing the windows updates. It froze for the first time during one of the updates and I was forced to hold down the power button to turn it off and back on. Now it randomly freezes all the time. When I turn it off and turn it back on, it freezes on bootup about 2/3 of the time. It seems to always freeze at the screen where the circular windows logo pops up right before you get to the login screen. Once I do get it to boot, I can use it for various amounts of time (sometimes up to 4 hours or so) before it freezes again. It freezes at all times, whether im on the internet or even when Im looking at the desktop with no programs open.
I did a lot of research online before coming here. I've tested my memory and hard drive and they pass every test. The weird thing is, even when I was infected I never had this freezing problem. I downloaded every (i believe) driver from Dell's website for this laptop so I dont think thats the issue. I was thinking it could be overheating, but then why would it just start happening now?
I plan on taking it back to Staples on Tuesday (unless they're open tomorrow) but I have a lot of online homework to do until then and when it freezes, I sometimes lose my work. Plus, the people at Staples dont seem like the smartest people in the world when it comes to this. Does anyone know what this issue could be from? Again, I never had this issue before reformatting and my computer is infection-free. Thanks in advance for the help! I'll be checking on this very often so if any more information is needed, let me know
I have 3 GB of memory, 120 GB hard drive with 70 available GB. Intel Core 2 Duo T5450 1.66GHz. Windows Vista Home 32 bit with Service Pack 2 upgrade.
