Hello, I purchased quite a good laptop about a year ago and there were no problems with it until a few days ago when each time I switched it on from a sleep mode, it started to take unbelieavably long for the log in screen to come up. The screen is black (blinks once in a while but only in the edges - I think thats the brightness light or how else would you call it) Then after about 6 minutes, the log in comes up and I have no problems until I go to sleep and put it into a sleep mode again. This problem now happens almost everytime i try to wake the laptop up from a sleep mode. The specs are: Intel Core i5-4210M CPU 2.60Ghz RAM 8GB 64bit OS Windows 8.1 and its an ACER ASPIRE V3 772G
