computer cutoff Monday around 8:30 am and was fine the rest of that day and Tuesday. Then Wed. it cutoff two times in a 30 minute span, late afternoon.
When I say cutoff, I'm not sure what is happening. Monday I heard a clicking sound in my tower before my monitor went blank. I thought surge protector and looked that way. It was on. I looked back at lights for the modem, pc, and monitor and all were on.
I had to manually turn the pc off and reboot. Once I did, I noticed I was not logged into my home page, so it seems like something is shutting down Windows XP and also logging me out of some sites. I've never had a virus do this and have had several viruses and malware attacks but nothing like this. Monday the inside temp. was about 40 degrees. It's been that way for 8 years and never any shutdown. Someone said, hard drives can act up with temp. variations and especially under 41 degrees. I've lost a couple mother boards. I've lost one hard drive (well the system would not boot to let me get data off the hard drive). I've got this pc in the shop and so far they have not found anything. Yesterday when it cutoff, or immediately stopped Windows XP, I immediately looked at my monitor and pc lights. I'm not losing power to my computer for an instant. Maybe something else. It's so cold on bootup, a noise in my system sounding like the summer time fan that comes on. So far we have two opinions. One is that the hard drive has a condensation problem due to 40 degree temperature parts, turning on and heating up. The guy in the shop says he has never seen a hard drive go like that.
