The problem is this, a few weeks ago my desktop PC broke down, for the third time in a month, which I soon had to replace due to my college course being IT related. I now have a new computer that has similar specifications to the preceding one which seems to be running pretty sweet so far, knock on wood.
Now I've taken on the task of repairing my old PC as a hobby of sorts, I know it's probably a lost cause, and I've now had an idea after remembering a conversation I had with my older brother a year or so back concerning motherboards, specifically I found it amusing that motherboards use/used batteries.
To the point, the old PC is suffering from a blue screen that occurs every time it passes the XP loading bar, just before the user log in menu. Now, seeing as the PC is about 3 to 4 years old now and I used to leave it running for days and weeks non-stop, I'm wondering if the motherboard's battery might be the culprit of my grief.
Here's a few specific questions I have:
1. Do motherboards use, or did they use, batteries?
2. Does the battery power the BIOS and when?
3. What does the battery actually do? - Just to satisfy my curiosity
4. Could the battery, in any way, cause my computer to receive a blue screen?
5. Is it possible to change the battery?
PS: Due to the inconvenience, I'm not actually up to plugging the machine in to check on anything at the moment, but I will be within the next week or two.
Thanks for any info or replies.
Edit: I haven't updated my computer specifications within my user profile, so it might prove useful while deciphering the problem.
