Here is my message from the Virus boards, except now I think its hardware, because of some new information I found.
On my computer, about 4 years old and fairly slow and outdated which I still used for holding files suddenly messed up. I had it off for about 4 days, then I turned it on and booted to Windows. Shortly after, it just cut itself off. I turned it back on, and it will freeze and random sections of boot. Sometimes it will get all the way to Windows loading screen then just freeze up and not move, sometimes it will barely boot up and about 10 seconds later it will just freeze. Its not a loading problem, because even if I go into the BIOS, it will load and I can change settings for maybe 10 seconds and it will just lock up there. I unplugged both Hard Drives, still did this. Not the RAM, not the processor because I removed it and put in another one, same thing. Not the video card, because even though I couldnt see, it would start hitting and loading up and I could see it stop responding. What would cause this? Motherboard failure? Virus? What could it be? Thanks.
UPDATE: But not, it will still freeze, but sometimes when I boot it up when it is supposed to be checking memory lots of ? marks are there instead, and it messes up. Sometimes when I boot, I can get into the BIOS but the letters to select the options are garbled, some dont appear at all and they look funny and messed up. Computer still just looks up at random times. I checked, and the CPU wasnt overheating, and thanks to some other advice I checked the CMOS battery and its fine too. Any ideas?
