Proabibly won't be able to help, but...
I got a new computer a couple of weeks ago and since then I've been having problems with it. When you press the power on all that happens is that the dell logo and the pentium logo appear, it doesn't load up windows or have the F2, F12 options at the top. The only way I'vew found to make it work is to turn the power off at the wall and then turn it and the computer back on again, then after it works that time the next time it doesn't again. I don't suppose anyone knows how to sort this out?
