Virtual machines aren't that hard to setup & run, the key thing to remember, is your computer capable of running these?
At a bare minimum, and I learned this the hard way, 4GB of RAM is needed. So is a dual core CPU, that runs at over 2GHz, one can be ran on a little less CPU, but the results won't be good.
Yes, deleting the ones that are giving you trouble would be good to do, as you can recreate these if desired. Or before deletion, you can look them over to see what needs changing.
So that we can better advise you as to your options, will you please furnish the basic specs of the computer you're running these VM's on? For example the amount of installed RAM & type, if you know, and CPU specs. These are the key players for running VM's & if too low, we can possibly spare you some trouble. Windows OS's will require the most resources, therefore I don't advise trying to run one when there's only 4GB RAM present, it'll be slow, your CPU will be screaming & a lot of heat will be produced in trying to run one on the bare minimums.
Hey Nick- I just got an unexpected bonus from work- so I will be headed to my local computer store tommorow to upgrade my RAM- my system will hold 32 gigs,so I'm gonna be a happy camper tomorrow!
Sounds like a grand plan to me, hopefully you can find a 32GB, 4 stick set (8GB per stick) for under $250. That costs less than 2 sets of 16GB, and much less than single 8GB sticks, which is not recommended & some brands will say this in their documentation, in a dual channel setup (most popular option), not to be mixing lot numbers in a channel, even if the model is the same. Like if you have 4 slots & you can't get a 32GB kit, then at least get two 16GB kits, and be sure to place each kit in the correct slots. Normally these will be marked for you by the color of the slots. In my case, two are off white, the other two black & they weren't in lined up order. It was like every other slot. This step cannot be overlooked, you may have problems otherwise.
The best place to check would be the OEM's site, there should be a section dedicated towards RAM replacement, which should show how to install dual channel RAM.
The type is equally as important, it may be best to run Speccy on your Windows partition & click the RAM tab, and print the specs. What you don't want to do, is purchase the wrong type of RAM, in the worst case, it simply won't boot, like if voltages aren't the same. In some cases, the consumer will be cheating themselves out of performance by not purchasing the max frequency possible (e.g, installing DDR3 1333 RAM in a DDR3 1600 ready MB).
Sometimes, these shops may be loaded up on a lot of a particular type of RAM & pushes it off on those whom doesn't know what to purchase. Or will simply examine an installed stick & not bother to check if it's the best performer for that computer. I cannot begin to count the days when customers were coming back home with PC2-5300 RAM sticks from the shop, when their PC's would take a PC2-6400 upgrade, a significant one, or worse yet, downgrade them to PC2-5300. Many shops loads up on 'safe defaults', and if they're re-installing one's OS at the same time, the customer won't know the difference, and worse, spread the word about how 'honest' they were.
Then when one comes along who knows what's going on, they want to cop an attitude, citing their extensive list of 'satisfied' customers & collective years of tech experience on hand.
That's why I purchase my RAM online, can email my Speccy specs to reps, and get a fast answer in return. GSkill is my choice of RAM, and they answered my contact on Christmas Eve inside of 3 hours, when normally anyone around would be at the office party. To their credit, I wasn't looking for an answer on that day, and was surprised to see it in my inbox. Newegg had it on promo, and that's when I pulled the trigger on my first RAM upgrade on the PC, if I had the funds, would have purchased both sets that day. The next set was purchased a month later.
Kind of surprisingly, while I noticed an instant increase in performance with the first upgrade kit, moving me from 12 to 24GB, barely seen one when installing the 2nd kit, other than when running VM's. Didn't even move the WEI up on the RAM scale, though the first set did. I suppose when one reaches a certain point, it's not seen at boot. What was even worse, when VMware Player recently upgraded, it showed a recommendation for a 6GiB Swap space. I gave it 4GiB prior, have drawn my line in the sand there. If 4GiB isn't enough, tough, it'll have to access my physical RAM. I'm not going to grow Swap space every time VMware Player upgrades.
Good Luck with your RAM purchase, hope they do you right.
