I have a rather old (maybe 7 or 8 years?) Toshiba Portege laptop that runs Vista. For the past month or so I've been experiencing random freezes. The screen becomes completely unresponsive and I can't even put the laptop into sleep mode. I have to hold the power button down, do a hard shutdown and start the laptop up again. Sometimes when I do that I get an error message that the operating system couldn't be found.
The freezing often seems to happen when I'm loading a new page in my browser. When I pull up task manager I also notice that CPU Usage jumps from the single digits to 100% for seemingly no reason...I'm not sure if that's normal or even related to my problem but am mentioning it just in case. It usually seems to be Chrome or tskmgr that's causing the strain. I've tried to be conscious of how many tabs I open in Chrome, but the high CPU usage and the sudden freezing happen even if I only have a couple open. I've also tried switching from Chrome to Firefox, but that didn't help.
I've run virus scans (Malware Bytes, Kaspersky and some others) but they all came back clean.
The freezing happens quite regularly. The laptop might be fine all day and then it will freeze several times in a row. (A heat issue, maybe?* The fan does run often, but it always has I think.) I'm wondering if anyone can shed some light on why it's happening and whether it's fixable.
I know my laptop is quite old so please don't feel you need to spend a bunch of time troubleshooting. If there's a relatively simple and easily identifiable solution, I'd love to hear about it. Otherwise, I can accept that I've gotten my use out of the machine and it's time for a replacement.
- The Perfmon scan I ran (Reliability and Performance Monitor.html.zip)
- Admin.zip (Administrative Events log from Events Viewer - I saw it mentioned in another thread)
If I need to do any other scans please let me know. Thanks in advance to anyone who's able to take a look at this for me!
*Update: I ran HWMonitor and I think the temps seem ok - nothing is higher than mid-50s.
