Windows 7: Getting BSOD every few minutes, problem with modidras.sys

Ok, Thanks for the advice.

I bought a can of compressed air today and tried to open the laptop but I was unable to do so because 2 screws were stuck .

I used the compressed air to clean the dust and so far it emits less heat than before.



I will do the other tests over night and feed you back.

I ran Windows defender offline quick scan now and there were no issues, or at least I think so as I was not prompted that there's any threat.

Do you recommend running a full scan ?

I think it'll take me another night for that.

Yes, full scans always.

OK

I ran memtest86 and after 90 minutes the laptop shut down.

I went to check and found extensive heat from underneath.

I don't have a cooling pad so I put two small blocks under the laptop to give some space for cooling and restarted memtest86, hopefully it will finish without problems :-(

You may have other issues, memtest creates very, very, little heat. See if your vent are clogged with dust, blow it out if so.

The test is still running after 9 hours,and it's on the beginning of the 5th pass with no errors so far.

12:30 hours, 50% of the 6th pass and no errors so far.

Memtest sound like it's doing well, complete at least 7 passes.

Yes, it finished 8 passes without errors.

After a couple of hours I'll start the Windows Defender Offline full scan and feed you back.

I have a question here, just in case I ended up without solving the problem.

My laptop didn't came with a separate windows CD, it came with a utility to take a backup of the existing system at that time, and I took my first back up a couple of months later.

I don't want to restore from the backup, I want to install a fresh copy, so if I can get a copy of windows 7 without a key and use the key that came with my laptop, will that be OK ? i mean will that copy identify my key, supposing that both copies are Home Premium.
