I booted up my computer (windows XP) and now the screen goes blank after the XP screen for about a minute, loading windows, then goes into windows and everything loads extremely slowly. Whenever I double click an icon it takes like 90 seconds for it to do anything. I have a c and d partition on my maxtor 20gig (c for os and d for everything else). Now it doesn't recognize my d drive. At first when I clicked on it, it gave the error d: parameter incorrect. I have restored to a previous time, no help (gave a message also that the d drive cannot be restored due to it being turned off before the restore point). Updated Norton and scanned the system (not the d drive) no viruses. Did a disk scan of c with no errors (won't do the d drive). Now when I try to access d it tells me it is not formatted and asks me if I want to do that now. About 5 days ago I put in a new waterpump for cooling. Everything has been fine until now. Is there anything to try before I reformat and reinstall? I was wondering if the hard drive (less than 1 year old) could be getting interference by the magnetic field created by the pump? I asked this question in the water cooling forum Link But I am posting here as well because I am wondering if it could be an os issue and see if anyone could steer me in the direction of a solution.
