Problem: For the past few weeks my PC has been occasionally freezing up while trying to boot windows; it stops when the screen goes all black between the green progress bar and the blue-green Vista welcome screen. Oddly, it always happens on a reboot, but only sometimes on a regular start-up. Even when it does start up correctly, it tends to hover on the blank screen for a minute or two.
I read through the tech question’s recommendations, but that all seems geared to security issues, and I don’t think that’s the case here since everything else has been ok. I’d heard of a similar problem being caused by the ram not being connected properly, so I’ve checked that it’s all slotted in correctly. I’m not really sure what other information would be useful here, so I’m just going to kind of ramble for a bit about some things that might be related, and if you want specific information I’ll reply with it.
This part is kind of a tangent, but in case it’s relevant I’m going to tell you a little about some heat problems I had before and what I’ve done since. For about the first two years I had this computer I had it in a bad spot and wasn’t really taking care of it, because I didn’t know any better. So I learned a little about heat issues, moved it to a position with better airflow, started dusting around it regularly, and periodically clearing the vents and insides with compressed air.
Last summer I had to replace my graphics card (I suspect due to damage incurred during the aforementioned early years), which I used as an excuse to upgrade even though it was probably kind of wasted on my system. Since putting in the new card, I’ve been distressed to see that my system was running a little hotter than it was before. Up until this issue I hadn’t experienced any problems, but my cpu runs around 40° C regular, maybe mid-50’s while under heavy load, whereas my gpu reports anything from 65-70° C while idle, and as much as 85° C during heavy loads. I’d read elsewhere that under 90° C was okay for a graphics card, but when I logged in to post, I saw this thread on heat issues and it’s got me worried about that.
Similarly, when I had the card put in, I needed a higher output power supply, so I went to Best Buy and had their guys do the upgrade. Because I haven’t had any problems until now I’m disinclined to think it’s a power issue, but the nature of the problem seems like a hardware thing to my (admittedly ill-informed) perspective.
Sorry for the wall of text, hope you guys can help!
