Can't login to wordpress/preview posts/upload images

Hi Folks, I wonder if you could help me as I’m at my wits end trying to figure out what the issue is.

I updated my site on sunday to the latest wordpress version (3.5.2) And since i did I have had no end of problems. Here are the issues I have been having.

1. Sporadically cannot login to wordpress admin panel, getting the 324 empty response error (same result in firefox and IE). This doesn’t always happen, sometimes I can login after leaving it alone for half an hour. Refreshing doesn’t work, it just hangs for a few seconds then I get the same result.

2. I cannot upload images, I get the simple message stating ‘error uploading image, please try again later’ the image does seem to appear in my media library and occasionally It will let me insert it, sometimes I get a blank space and no image.

3. Previewing posts is also an issue, I have written a test post and when clicking preview post I get empty response error 324 or similar in firefox and I.E

4. I have also been getting the white screen of death on occasions when switching themes.

Here is what I have already done to try and recifty the issues but to no avail.

* Disabled all plugins
* Reverted my theme back to twentyeleven
* re installed a fresh copy of wordpress
* reverted back to an older version of wordpress
* re installed windows 7 from scratch (to eliminate computer issues)
* Contacted godaddy on several occasions, to no avail

All this only started occurring after I updated, which makes me believe it’s either a database issue or a host issue, but godaddy say they can’t replicate the problem. I am quite happy to jack them in and move elsewhere but I want to eliminate all possibilities before I do that

In my sites current state I am using twenty eleven theme, with no plugins and no other themes installed. The only thing I have uploaded is my database so you can see my posts with no images (I haven’t uploaded the content folder) And I am still getting the above issues.

I would appreciate any ideas and input, I have provided a tracert too just in case line 3 has something to do with it. Thank you in advance for your help.
