The issue is shortly after booting and logging into windows xp, my system freezes. The mouse still works, but it is unresponsive. Also, it makes a good bit of noise throughout the process and up until it freezes. Its always a matter of minutes before it happens. So far the problem hasn't occured in safe mode.
I've done the following:
Multiple virus, ad/spy/malware scans.
Memory diagnostic utility.
Hard drive diagnostic.
All of the above come back clean. I recently installed a gig of ram, though that was about 2 weeks ago, and everything was running fine until yesterday. I removed the new hardware and booted without it just to be sure it wasnt damaged. Computer still froze, even without the new ram.
Any suggestions would be much appreciated. I really dont know where to go from here.
Thanks in advance for taking the time.
p.s. The PC is an HP Pavilion a350n. If anyone can help, I'd be glad to provide any other information necessary. I must admit, though - I would need you to describe what to do.
