I've had windows 7 ultimate 64bits for a year now on my brand new pc, and today he starts and slowly ... around 35 mins to show desktop and will take forever if i click anything. I restarted in safe mode and it works perfectly, there are no exclamation points on the device manager. The only major change i have done but not recently was my video card from Nvidia to raddeon saphire. Can anyone help me fix this issue please
If it takes that long in normal boot, then you are most likely looking at malware problem. But first, I would do some general maintenance. Run defrag and chkdsk. Then run hardware diagnostics, specifically for the hard drive. SeaTools for Seagate, DFT for hitachi. etc.
