Win-7 Refresh Hangs Up Intermittently

Since June 2013, yes this is September... I have spent hundreds of hours trying to resuscitate my ASUS K42jr, Core i5/AMD Radeon laptop computer. I am very frustrated to say the least.

In June I did a Win-7 reinstall from a hidden partition on my Acer laptop by the request of Acer support regarding issues I was having with an erratic touchpad on that computer. It was completed and with great success. That laptop finished up so like new that I decided to do it also on my ASUS from the hidden partition in its HDD.

I reinstalled Win-7 (sans SP1) eight times on the ASUS but was never able to insert the SP1 update and the O/S was obviously defective after each reinstall and/or there was no successful start-up. Next I followed the instructions on one of these sevenforum threads for a "Clean Reinstall of Windows 7 on an ASUS". In that tutorial I found how to use external software to merge SP1 into the O/S install and also include the 145 updates that have occurred since that post. I made a bootable USB and I was so glad to find that everything finally "got in" and Windows 7 actually booted.

But... What I now find is that frequently I can not close program windows without experiencing a snag and/or a hang-up of the system. Additionally when running Windows Defrag it too will hang-up and not complete. Internet pages hang, even Notepad hangs and sometimes shut down hangs and doesn't respond. EXCEPT and this is an interesting observation, If I Ctrl/Alt/Del the requested activity is "Pushed Through" and the system generally responds immediately! (BTW, the install is virgin, there are no installed programs, Only Windows 7 with all of the updates resides on the computer HDD, ca. 21GB is all that sits on a 500GB drive)

I have run memtest86+ on the 4GB RAM and HDD diagnosis on the internal boot drive, a Seagate 500GB 7200RPM HDD and neither is the culprit. I'm stumped. The only issue I have ever had in the past with this laptop was solved in 2010. On its first start up there was an issue that regarded "classpnp.sys" and it went away with some kind of a manual fix that I no longer remember. I have not thought that was also needed with the new final SP1?

I really respected this laptop and ASUS because of the speed and pleasure I experienced with it. I had never had an ASUS and was impressed with the quality of the components. I WANT MY OLD ASUS COMPUTER BACK! How can I make that happen???

Hello and welcome umanemo mate if you are trying to just do a reinstall you might be interested in this Clean Reinstall - Factory OEM Windows 7

this will install without the bloatware from Acer too.

Now I could way out here unenamo but maybe it is a hard drive or RAM problem problem.

Now I don't know what drive brand you have in it so can only suggest we find that out - use Speccy Speccy - Download (from piriform) go to the hard drives and it will throw the model up depending on what brand it is the appropriate test gear can be used. Post back if you are not sure which to use because some do other brands mate.
You can always use the Partition Wizard to do a physical surface test too.

The RAM test RAM - Test with Memtest86+ you will need to make a bootable disk set the BIOS to boot from the optical (USB is you use a stick) boot and let the test run for at least 8 passes unless it throws up any errors straight away. Any less than 8 passes is not much good. It does take a long time and something some set to run overnight. But at least it will help us rule out those problems if they exist.

One other thing have you tested the power adaptor mate for volts? It may not be supplying those correctly or enough current the latter is hard to know unless you have some ammeter of some sort - but the volts may give some indication if they are out of whack.

PS I meant to say pick the C: drive at the end where I have highlighted my backup drive for the surface test

Hmm sorry about that umanemo I missed that in the haste.

Well I suppose the other option would be to do this if you have no data to save and it will get rid of all the Acer bloatware too.

all you need is that code on the sticker on the bottom of the machine - you will see that in the tutorial.

What are your temps looking like? What does speccy report? Can you save a log file of the speccy report and upload it?

Umanemo another you can use is this too. System Info - See Your System Specs but the Speccy will be good for temps as well.
