Computer freezes a lot, often at startup

Hi, my computer freezes all the time, often right after startup. There is no blue screen or anything. Everything just freezes and I can't do anything (Ctrl-Alt-Delete doesn't work, etc.) so I could only hit the power switch to turn off the computer.

I've run the DM Log Collector and have uploaded the file here. However, it seems a lot of the info are 0 KB. If you need more info, I can run the SF Diagnostic Tool (I've been on this forum before, and it's been great before, and I've run that then; not sure if it's how it's done now). Anyways, please help. My freezing computer is driving me nuts!

Hi Ray,
when it freezes, is it just a blank black screen, if so had you scheduled either dskchk or sfc scannow to run on next boot?

As it's a 5 years old computer, the heat sink can be blocked with dust. Or even the fan isn't working.
Open the case, remove the fan (not the heat sink, and with a paint brush, clean it.

Install a temperature monitor. Downloads - Open Hardware Monitor

As Torckwood recomended, schedule a disk check and on a CMD type sfc /scannow

Thanks for the responses. I'm going to run the recommended programs and get back to you.

It's never a blank screen. At startup, it goes to the desktop, I see my icons, but then I can't open any programs and it just stalls.

I always run Speccy in the background and the temperatures are always low (see screenshot). I checked the fans just now. They were relatively clean (I cleaned them just a month ago) and they were working.

as you can have a corrupted file, schedule a disk check and on a CMD type sfc /scannow

OK, I've finished the steps--CHKDSK and SCANNOW--and I've attached the results in a zip file. I followed the scannow steps illustrated here:

And for CHKDSK, I just restarted the computer in safe mode with command prompt.

There doesn't seem to be any problems. What is the next step? Thanks a bunch!

Run a memory test

- Click Start, type mdsched.exe in the Search box, and then press Enter.
- Choose whether to restart the computer and run the tool immediately or schedule the tool to run at the next restart.
- Windows Memory Diagnostics runs automatically after the computer restarts and performs a standard memory test automatically. If you want to perform fewer or more tests, press F1, use the Up and Down arrow keys to set the Test Mix as Basic, Standard, or Extended, and then press F10 to apply the desired settings and resume testing.
- When testing is completed, the computer restarts automatically. You’ll see the test results when you log on.

Note that if a computer crashes because of failing memory, and Windows Memory Diagnostics detects this, the system will prompt you to schedule a memory test the next time the computer is restarted.

OK, I ran mdsched.exe at startup and left the computer while it ran. Then I heard the computer restart. However, when it did, it froze again at startup (I see the desktop but I can't access any programs). I saw no test results. I had to manually turn off the computer twice before I could get to a desktop where I can access programs. Again, I saw no test results.

I went to the Event Viewer and could only find the following (please see the zip file, which contains screenshots). Also, there has been a BSOD since the last time, but there was no memory dump; it just froze at the BSOD forever so I had to shut down manually. Please help.

Memory test can last a day. If the computer booted in minutes, run it again and stay close for about 10 minutes (fist pass).

You can clean the memory contacts.
- Shutdown, remove the power cable from the power supply and wait 1/2 minute.
- Remove one memory stick at a time and clean with a cloth with alcohol. Let it dry before inserting back into the slot.
