My TCD652160, which worked beautifully for a long time now has problems. It worked great until about a week ago, and then started rebooting more and more frequently. It got to the point it would only run about 10 min, and then reboot. I tried kickstart, but no success. After researching, I opened cover and had one swelled capacitor, which I replaced. This improved things quite a bit, where it will now run about 1-1/2 hours or sometimes longer, but then instead of rebooting, it just totally locks up and I get the GSOD. The only way to get it back is to power cycle. I've tried running the various kickstart codes, which all succeed, except the overnight test, where it locks up somewhere during the process and won't finish. I'm trying to figure out if I have a likely hard drive problem or if there are other power supply problems. It doesn't seem like it would be the power supply, because it can have been in the lock up mode for hours (warm/hot components) and it will still reboot and work okay for about the same time period. In other words, it doesn't seem to make any difference if it was powered down for an extended period, with cold components or not. On the other hand, I'm not sure it's the hard drive either. I'm tempted to replace it with a new one, maybe from a seller on eBay, that already has the image, but I really don't need the larger capacity all that much, though it would be nice. What do I look for? I've read that voltages are difficult to check on the power supply's, and you can get get proper voltages and still have a bad supply. Or is it more likely that the image on the drive somehow was corrupted, and is causing the problems? It is interesting that it works for a while, but suddenly and inexplicably locks up. The interesting part is that it no longer ever reboots, but instead, always just locks up with the GSOD. To me, this seems that it's probably the drive, but then again... If I buy an ebay drive (I don't have a PC with a SATA port, and don't want to spend the money to get one, or buy the CD needed, or take the time to do it), are there any recommended sellers? I see DVR Dude and uoph as the most common sellers of imaged drives. Anyone have any experience with either?
