Laptop randomly freezing up

i have a Compaq, windows 7 laptop ive had my laptop for about a little bit under a year now maybe 9 or 10 months , my laptop recently started acting up about 5 months ago , it was running sluggishly and also while using my laptop for about an hour it would suddenly begin to get glitchy and when i move my mouse the cursor would move little by little very slowly and glitchy for about 30 seconds then the laptop will completely freeze , i thought it was a malware problem so ran some programs that was told to me by a professional on my computer , after that my computer sped up and was working smoothly the pop-ups went away , but still my laptop randomly freezes i have to hold the power button down to reboot it when it freezes and when i start it back up it stays on the windows start up screen and glitches while the windows logo builds up for a very long time maybe 15 minutes then when the windows logo finally builds up it freezes and doesn't go past that , i do the same thing to reboot it for a third time and the laptop works perfectly fine and there's no problem , later in the day maybe week the same thing occurs, i believe it is a heating problem and want to find a way to fix it , please bear with me i don't know a lot about computers and laptops

thanks for reading

Can you tell us what you ran to remove the Malware and what it found.

Have you run any other software to try and diagnose the problem?

Please install this software CoreTemp and tell me what temperatures it is showing when the PC is running with no other software or internet browser open.

i will install tht program later when i get on my laptop , also here is the link to the threads where i was told how to remove malware http://www.techspot.com/vb/topic177428.html this guy really helped me with speeding up my system

Ok, I've followed the link you gave and see Broni has done a thorough check for Malware and a clean up.

Once you have the Core Temp software installed, let the PC rest for 10 minutes and tell me what temp it shows.

it runs at about 50-52 degrees Celsius

That seems a bit on the hot side, should be nearer to 35ºC. What does it go up to when running Video or playing a game?

Have you had this PC from new or was it second hand?

bought it brand new , now it shows 43 degrees and where it says Min. it says 30 degrees and where it says Max. it reads 70 degrees

5 minutes later the temperature went up to 51 degrees

after about running a video on the computer for about 3 minutes the temp went up to 54-55 degrees

when i closed the video program the temperature went to 52 degrees

when i watch a video off youtube its at 56 - 57 degrees

the longer i use it the higher the temp

Ok, those temps are within acceptable limits, some laptops do run a little warm but as it is not rising too high when running video the temps are unlikely to be the problem.

How high does it get after an hour or so?


Run this and post the log:

• Click on Start > type cmd in the search box. A box will open with CMD at the top, right click on it and select Run as Administrator. Another box will open, at the prompt, type chkdsk /r and press enter. (Note the gap between the k and the /)
• You will then see the following message:
• chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)
• Type Y for yes, and press enter. Then reboot the computer into normal mode.
• chkdsk will start when Windows begins loading again. Let all 5 phases run and don't use or turn off the computer. (The chkdsk process may take an hour or more to finish, if it appears to freeze this is normal so do not interrupt it.)
• chkdsk finds any corrupted files and fixes them. Read the results of each phase as it finishes. During the final phase, it will notify you if it finds any corrupted files. It will also report on finding any bad sectors on the hard drive, these will be blocked from further use and the data on them moved.
• When the Disk Check is done, it will finish loading Windows.

Then follow this guide to find the chkdsk log.
Windows 7 Disk Check log

Once the log is in view then click on Copy in the right hand pane and select "Copy details as text".
You can then right click on the message box on this forum and select Paste and the log will appear, add any further information asked for and then click on Submit/Post Quick Reply and your done.

i have did the chkdsk thing but when i rebooted my laptop it loaded back normally , i think i skipped the part where you were talking about To run on an external drive use chkdsk C: /r replace the C: with the appropriate drive letter. im not sure if thatts the problem

You must have missed something if it rebooted without running the disk check, try going through it again.

This part:

Is only to be followed for running the disk check on an external USB drive. As you are running this on an internal drive you can ignore it.

i dont understand that part , sorry , im not much of a tech genius please explain

No need to apologise, it is wise to ask if you do not understand something or you won't learn .

If you are referring to the part I put in a quote box in my last post, as I explained, you can ignore it unless you are running the disk check on an external drive.

An external hard drive would be in a seperate box that is connected to the PC with a cable and a USB plug attached to the PC.

I would suggest you print out the instructions so you can follow them easily when they are not on the screen.

Please ask if you are stuck on anything else and give full details of anything that doesn't go how the instructions say it should.

It's 2AM where I am so will be turning in for the night. I'll be back in the morning GMT+1.

Take your time with the instructions and see how it goes.

i dont use an enternal USB drive

That's fine, to make it easier for you I have edited the instructions in post 13 and removed the part about an external drive, just follow the instructions as they are now.
