I'm running windows xp pro SP3 on the desktop I built(a couple years ago), and recently it has been having problems:
So, I'll start from the beginning of my problems. My computer was randomly freezing at times, so I figured it was malware/etc..(by freezing, I mean the current program would not respond, and I couldn't do anything but move the mouse) I scanned my computer and nothing was found. I ended up doing a fresh install of windows to see if it was a software problem. After reinstalling my drivers, It was somewhat slow and still would randomly freeze, so I remembered it was probably about time to dust out my computer. I dusted out all my fans (my CPU heatsink had alot of dust in it.) That seemed to speed up my computer to around how it is supposed to be, but it still was freezing. Occasionally after restarting the computer after one of these crashes, it would automatically run a DSK CHK before startup. Now it won't load windows at all. It will bring me to the screen with "last known configuration / start windows normally", but at this screen my keyboard doesn't work. If I let the timer run out under the "start windows normally" option, it displays the text:
Windows could not start because this file is missing or corrupt:
"you can attempt to repair this file by starting windows setup using the original setup CD-ROM"
It did this once before, after a freeze, and then I was able to fix it by putting in the disk and replacing the file via the recovery console. The problem is, now at the screen "press any key to boot from CD" it doesn't recognize that my keyboard is plugged in. If I go into my BIOS at startup, my keyboard works there, but no time else during startup.
Any ideas as to how I can fix my computer? I don't think its a problem with interior fans/ heating, as I've had this current computer with this setup for a couple years, and never had heating problems. When it was still starting up, I tested each of my RAM, and they all seemed to be working fine. I did notice that my Graphics card was running extremely hot (to the touch) but from what I've read online, they can get very hot. I've checked my motherboard's capacitors, and none of them are bulging/ leaking. I think my power-supply might be the culprit, but I've no way to test it. I don't want to be throwing money left and right on new parts only to find they were fine to begin with, so I'd like some input on what the most likely cause is. Thank you for your time!
