Getting stuck at starting windows screen, windows logo absent

Hi all,

So I have a dell optiplex 755 and have windows 7 n (the euro one w/o media player) installed and for the past 2 months the following situations have been recurring:

Start windows and boots successful
-after leaving my computer on for an extended period of time and then waking it up from "sleep" it would abruptly shutdown and then restart.

After a couple times of this happening it would then repeat the same process however it would randomly go to startup repair, run start up repair which wouldn't find any solutions and then turn off the computer. I would then sometimes turn on my computer and it would run fine and I would be able to get past the starting windows screen.


Recently I have had the above process repeat several times with being able to get passed the windows starting screen only once in about 20 tries.

I called dell and the operator mentioned the "fbi virus" right away but then wanted me to pay to have it fixed by remote access however I am short on cash so that was out of the question.....



Sorry for the length of the description, if you are confused at all by the wording please don't hesitate to ask me for further description.

Any help is appreciated!
