Hey - Just wondering if I can get an opinion on what might be the problem with my PC, I think it might be on the way out but really dont know enough to guess. Here's the problem..

Since about 2 days ago I've been having trouble getting my PC to start atall. If I boot up it loads normally untill I get to the 'Windows XP' screen. The blue bar below the logo moves along until the screen flickers slighty once and the bar freezes in place. Leaving it to load does nothing as it stays frozen on this screen. I'm forced to restart the PC and try again. It usually takes me anything up to 10 restarts before I get in and past this bar. Also each time I reboot it asks me if I want to start in safe mode, which I have tried. Problem is the PC freezes everytime I start Safe mode without fail, unlike normal mode which eventually will get in.

I thought it might have been a problem with Windows so I did a full wipe last night but its still happening. I think it is a hardware problem rather than a software. Any ideas? Cheers
