Hi there. This is my first post. Lately when turning on my PC, it is freezing on the BIOS screen. It is identifying my drives but then just stops and does not start windows although this morning after numerous restarts, it did start windows but only after a long period. My system is over 3 years old and I have an Asrock motherboard with a 1.86MHZ dual core Intel chip. I am running Windows 7 Ultimate. It seems to me that there may be a problem in the handover from BIOS to Windows but that's just me. I am a reasonably experienced user. I am thinking that some components may need to be replaced and any advice would be most welcome. I am leaving the PC running for the time being and will be doing a full system backup tonight. I look forward to any advice given. Thanks
