Hey. I have recently acquired a problem when I leave my computer on, it will shutdown in about 15 minutes when the screensaver comes on. It also crashes when I run windows media player, and some other games. It does boot up automatically again, but it says there is a boot disk error, and it won't find my hard drive until I swap the sata port. I thought it was a heat issue, I do have fans to cool it. I thought it might be my graphics card, so I purchased a new one (which I wanted to do), I even changed my power supply to a bigger wattage. I am tempted of getting a motherboard which I don't want to do it's my last resort.
Check your Power settings in Windows. Reset CMOS to defaults. How old is it? You may need to replace your CMOS battery, most likely a lithium "coin" cell. CR2325 or CR2025 are two common sizes used, but check before you buy one.
The system is about 3 years old. I resetted the cmos, and it still shuts down. Hd tune said there were a few warnings. I found another diagnostic for my hdd and it said that there were bad sectors, and it didn't finish the tests, it went to a bsod. So I'm now thinking a bad hdd? I don't have another hdd to test out this theory yet. Would just reformatting the hdd solve it?
Maybe, maybe not, but probably not. It may offer temporary relief, but if you've had a crash, there are all kinds of nasty particles in your drive, just waiting to get between the head and the platter to cause another one (and likely flinging up more particles).
You don't want to do that, since some files may be corrupted. Install Windows and all your programs fresh on the new drive. You may be able to copy data files off the old one.
Yeah, forgot that one...CR2032...
