Mid 2010 MacBook Pro 13inch - Issues w/ all browsers
Hello all! Please read the entire post before replying. I have attempted several fixes for my problem based on other posts, but to no avail.
Problem: My mid-2010 MBP is having issues w/ all browers (Safari, Chrome, Mozilla). Simply, I'll be online with email, reading news, shopping, working, etc. and the browser is working fine and then out of the blue when I attempt to go to a new page the status bar will load about 15%-20% (as if it's working properly), then stop and advance no further. The remainder of the page will not load and I am unable to do anything online. This happens regardless of the browser I am using. The only immediate fix I have found is to quit the app and restart the computer. I have had this problem in several differnet locations and on several different networks. There seems to be no rhyme or reason as to when or where this happens. There are sometimes where the browser works fine.
Attempted Solutions:
1. Uninstalling and reinstalling all 3 of the above mentioned browsers. Didn't help.
2. Purchased and Installed MacKeeper. Ran scans to check for viruses, maleware, etc. - any issue located was dealt with appropraitely. And the problem persisted.
3. Ran Apple Hardware Test from the disc that came with my MBP (Both quick and longer versions of the test). No hardware issue was located.
4. Ok so maybe the issue is software. Attempted to reinstall Mac OS X from disc that came with my MBP (Snow Leopard). Please note that my current OS is Maverick 10.9.2. Upon restarting with "C" help down, I begin to navigate through the prompts. About step 3 where I must select the startup disk, I chose the local HD. I receive an error message at the bottom that I cannot use my local HD as the startup disk, but there is no other option. I am not sure what's going on here. There may be an error with running Maverick and attempting to go backwards to Snow Leopard, but if the issue is software OS related how can I reinstall my OS?
The only next option, that I am aware of, is to replace the physical wifi component as that might be the issue. However, the Wifi signal always shows there is a signal and will dsicover mutliple networks (where there are multiple networks).
Does anyone else have this problem or know of a possible solution I haven't tried?
Thanks in advance!!
MacBook Pro, OS X Mavericks (10.9.1)
