| Firs time for everything. You guys think this is repairable, or just have to replace it? Posted: 23 Jul 2019 10:54 AM PDT This started on this thread where I was trying to solve a random dpc_watchdog_violation BSOD but couldn't boot to to USB devices. Resolved that and was able to run full MEMTEST which passed as well as boot to linux on USB and let that run a while and it was stable. Ended up installing a new SSD and clean Windows 10. Went fine, updates were coming in. Rebooted, about 5 minutes in, froze and BSOD again. So now I know its hardware. Started doing a little disassembly and noticed the CPU heat sink screws felt a little loose on one side. Could it just be a thermal issue? Usually those shut the machine right off, not BSOD. Maybe Windows is telling the CPU to change speeds due to heat and it can't because of thermals and then we get the BSOD. Not really sure. What I do know is that I found that the two screw mounts are just totally broken off the motherboard. The actual copper plate on top of the CPU never felt hot, but now I am wondering if that is just because it wasn't making good connection. Anyone know if these things can be glued back in, or is this just new mobo/junk it territory? First time I have run into these things actually coming off the board. [link] [comments]  |
| Posted: 23 Jul 2019 07:09 AM PDT Working on a laptop with a really intermittent blue screen error (the most fun kind). At this point we need to do some stuff like boot a linux live OS and see how it behaves, run memtest, etc.. but I can't get the thing to boot to anything but the internal HDD. So I think I am really just looking for confirmation that this thing has a hardware problem. What do you guys think? It is set for UEFI but won't boot to a EFI USB key with memtest on it, or a Windows 10 installation USB. Tried in both USB3 and USB2 ports (laptop only has 1 USB2 and 2 USB3 ports total). Tried turning off secure boot, tried changing UEFI to CSM (legacy) and trying both USB2 and USB3 ports when changing between them. No change. Boot menu hitting F12 or going into boot order in the BIOS only shows the HDD. Connected a USB DVD drive and that doesn't show up as a bootable device either. Has no internal DVD drive. BIOS is the latest release (I think, the download page when I enter the exact serial number lists 2 bios downloads, one is V1.2 which is what is already on there, the other is V5.1 which in BIOS revisions makes no sense and makes me very wary about trying to download and install that. Release dates of course are the same date because that is how Toshiba does things on their download site), laptop isn't super old (5th gen i5 CPU). Pretty much out of ideas and I can't even clean install if I wanted to if I can't boot to a USB. Model is a toshiba satellite p55w if it matters. EDIT: Since people have still been replying, I did get this resolved. After a little digging, I found out that the V5.0 and V5.1 BIOS downloads were compatible with this system, even though the current bios was V1.2 and there is nothing in between. They just decided to jump from 1 to 5. I was reluctant to try it before confirming that because I have seen on so many of these mfgr download sites where they don't give you the right downloads for your specific machine. Or you type in the exact serial number/service tag and they give you 5 different ethernet mfgr drivers, Intel, nVidia, and AMD graphics driver downloads, 3 wifi drivers from 3 companies. It would seem like from a serial number they should be able to filter to your systems specs, but that is asking way too much I guess. Anyway after updating to V5.1, USB boot is an option. Didn't fix my blue screen issues though, which I now think are due to 2 of the 4 nuts that hold the heat sink on top of the CPU were broken off the motherboard. [link] [comments]  |
