Windows won't install

That's a new one--why the downgrade? 8.1 fixed most of 8's problems and handles multicore processors much better than 7.

Huh, I haven't run into a single problem with the 50+ games I have on Win 8.1.

Sorry I couldn't help.

May I ask what process was undertaken to roll back to windows 7.. I know its a stupid question but sometimes a silly mistake can hinder a OS installation

If you did a full installation did you remove all the partitions or just clear the data from the windows partition?

Sometimes windows installation does not like this.... Don't ask me why its just sometimes it seems to throw an error...

If you have no data which you want to keep try formatting the partition you wish to install windows on before you install

try that and see if it works if not we can look further

Normally from what I seen the best and cleanest solution, download DBAN, wipe the HDD clean, install OS, done. There is no way to really 'downgrade' with all the apps in place and all that. It always flubbers up because there is differences in the OSes that linger and eventually 'crap' out.

Sorry i jumped ahead of myself...

Do you have a system spec or a model number?


There could be a hardware, software fault or even in some cases a installation media problem. can look at it more after you supply the details

Give me a short time and I will see what I can find... A cursory investigation into your problem seems to point to overheating... have you had problems with this before?

I will go check to see if there are any reported problems with your config and get back to you.

PS. Does it always get to the same point and shutdown or is it random? eg always 50% or between 40-70%?

From what I can see there are little or no reported problems of this type and your hardware configuration. are you using an original copy of windows 7 or are you using a downloaded ISO.

If you are using a downloaded ISO did you get it from Digital river
If you are using the original copy could you download a new ISO from digital river and install again ... I would suggest installation from a USB drive as this will rule out burning and DVD read errors

This now seems to be a case of trial and error from my point of view... because windows is not installed there is a limited amount of information available to us which can aid us resolving this problem

From what I can see other users have experienced this problem due to following:

Overheating (but you say that this has never been a problem before)
Having multiple Video Cards (after market installations or upgrades)
Wrong Bios settings (many factors including turning off AHCI)
Corrupt Installation Media

I would ask you to try it two more time

firstly disconnect everything other than the mouse and try again... sometimes peripherals can interfere with the installation of windows if this does not work try disconnecting everything other than the keyboard (both these setups will still allow you to install... if you use the keyboard only using the TAB key will allow you to proceed to the next box... its a bit of a faff but this works sometimes.

if that doesn't work I would start with the most obvious and easiest to resolve in that the installation media is corrupt

My next option if the installation alternative is to delve into the bios and turn off items which dont need to be switched on (bluetooth, Wifi, NIC... whatever your bios will allow) and choose IDE rather than AHCI... if this works you can switch them all on again and refresh your device manager if windows does not detect them during startup

My last option (final straw) would be to pop off the fan and remove the thermal paste and re-apply... I would not try to do this unless you are confident that you know what your doing as simply attaching the fan wrong will blow your processor

In the previous post I asked did you have windows 7 installed previous which I cannot see a reply

Please let me know if any of these options work... if you need links to download media please let me know and I can point you to the correct location to download a microsoft verified ISO (all you need is the details on your key... usually under the key there are two sets of numbers which are for example X123 12345 in configuration... this will let me know what build to point you to

Sorry about the late reply
My next option if it was me troubleshooting this problem would be to swop out the Video Card for a cheap off the shelf standard card and try installing from that... If this fixes the problem after installation shut down the machine and install the previous card and reboot and if alls well install the software

It may be a simple driver problem if your quick try to visit the manufacturer and see if they have updated software... I really do think you may have a problem with overheating on your GPU... It may be co-incidental that the problem arose when you tried to install windows 7... these things happen more often than you think

If that is correct, your AUX heat indicator (in the case on the motherboard) is showing your melting it down a bit (125C!?!?!?!). I would reassess the airflow by checking all the wiring, make sure the air is reaching the mobo. You can always check with some incense, see which way things are blowing or not blowing at all.

His AUX sensor is obviously broken...your computer would be smoldering at that temperature. Everything else looks good! That Phenom is one hot cookie--don't let it get over 61°C for any appreciable length of time.

I don't have this setup but I'm assuming if its anything like mine if the temp reads too high my heat monitoring software shuts off the offending piece of hardware to stop damage occurring and if that's the case it could be why this video card is powering down... Like i say I can only speculate
