I have a Dell XPS desktop running Windows Vista that while old, seemed to be happy. Suddenly, in early March, the system would just start freezing whether online or offline. The mouse simply wouldn't move. The only thing I could do at that time was a cold boot. In fact, I'm trying to type this before it happens again as it has been happening fairly quickly. Meanwhile, when the system works, it appears to work even faster than it did before. I did a Sea Tools for Windows extended scan and the system passed so I then assumed it wasn't hard drive damage. I tried to do a Dell system scan and the system would crash during the scan. When trying to do a defrag, I would get that cycle spinning that says it's doing the defrag but I don't see those progress lines showing. I was not able to do a system restore. Chkdsk couldn't complete; it got to step 5 twice and Windows startup repair didn't work but the system would start afterwards from a cold boot.
So I'm wondering if I need a BIOS upgrade (but am worried if the system crashes during the upgrade, my computer would then become a doorstop), if the recent Microsoft updates that have caused people issues with newer systems have also impacted on Windows Vista or if it is a motherboard issue.
When this started happening, I went out and bought a new computer, thinking "the end is near" as this computer has served me well for 6 years but I don't like to give up on a challenge and as I have a new computer and have saved all my data files, I don't mind "fooling around" with this one, considering that it only has a year anyway because Microsoft support for Vista ends next April and I wouldn't run this online anyway without Microsoft updates.
I'm trying to avoid re-installing Vista with the Dell Recovery disk but that might be my next step. I would hate to do that and find the system still crashing afterwards so I'm not sure how to troubleshoot this issue.
