Well first off I know very little about computers. It takes me 4 restarts that I have to use the Power button before my comp will go into Windows where I can actually use the computer. Otherwise its just frozen, sometimes with a blank screen, sometimes with a loading bar under the Dell logo that won't load all the way to the end of the bar. When I do get into the computer where I can use it, I've seen a small window that pops up saying Windows had problem turning on.
My question is, do I have problems with both hardware and software? I called Dell and they told me to press F12 and run a 30 minute diagnosis. The test said no problem with hardware, and my computer did run a little better for two days, but now is getting worse again. What do I do? Do I also clean the fan?
I don't have virus in my comp, I already backed up all my files and I did a system restore to an earlier date but the earliest date available was still after the time my computer has a lot of problem.
