There are usually two methods the case can come off: 
-plastic clamps or grooves on either side of the tower, usually on the middle or back. they usually unsnap, or provide leverage to slide the panels off. 
-a set of screws on the back of the case. If you take a look at the back, you should see two sets of three of these, one set on the left on set on the right. take the set corresponding on the panel you want removed off, and you should be able to slide the side panels off, and get to your motherboard to install the RAM. 
- in some cases, the top and sides are actually part of the same piece. to take these sorts of cases off, you will need to unscrew or unclamp both sides on the back. when you are finished, try to tilt the casing sligthly upwards, and pull the sheet off. 
hope this helps. let us know if you need any more help ;)

Can m7357c run games well

we dont know your budget.
each game made as s product page online, with a section
that tells you minimum system spec.
if bought from any store on DVD the box side clearly states this.
so... now you know the minimum. easy as apple pie
next comes to whats in the PC box.
we know know. we'd have to take the lid off and look
HP Media Center m7357c Desktop PC Product if you google that the products spec, is like published a zillion times.
no lack of facts on it , if not upgraded.
circa 2005
PentiumD 920 (P) DC 2.8 GHz
300gb HDD(read tiny)
1.5gigs of ram, way to small of new OS, hopeless small
with 3 years dead OS called XP.
no hope of running w7 with tiny memory, w7 is bloated now with 3 service packs, and 300 updates and IE11 mandatory to use it.
most games tell you w7 or newer and 4gigs of ram
why not just try one, game, you will cause no damage
(assumes not filling up the 300 gig HDD full)
Try and learn what works an not, its always good to learn.

Hallo to Experts plz any one will help me.dearz my system is gx270 dell.its back lights A&B remain orange while i start p.c plz any one tell me about it plzzzz...

This generally signify , that the memory modules are detected in the system, but there is a memory failure.
You can try the following steps
  • If you have one memory module installed, reinstall it and restart the computer.
  • If you have two or more memory modules installed, remove the modules, reinstall one module, and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error.
  • If available, install properly working memory of the same type into your computer.
In case you need a user manual to know how to open the computer tower you go the following link

Yes I would have thought so. The blue screen is most likely caused by some memory. If it was working ok before installing the new memory, then it is either the new memory, or a faulty memory slot on the motherboard

My monitor works fine but there's no picture and the tower is on.

you have a memory problem,

  • If you have two or more memory modules installed, remove the modules, reinstall one module (see Installing Memory), and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error.
  • If available, install properly working memory of the same type into your computer (see Installing Memory).
  • If the problem persists, contact Dell (see "Contacting Dell" in your Owner's Manual).

Install 2 RAM modules of 1 GB

The other memory may be soldered in. Check your manual and see if it has any information on additional memory. If you only have on expansion slot you may have to buy larger memory chips. like instead of 2 chips 1 gig each you may have to purchase a 2 gig chip. Computer companies usually make the chip installation easy to get to on lap tops.

Removing cover on gateway 300

This a tower right? I don't have a gateway but I have a dell and a compaq tower they come apart pretty much the same way. The left side panel slides out by pulling from the back. Some may have a screw or two you have to loosen or take out. Then you can either slide it by pulling from the back or there could be a latch that you slide to unlock it. Wow I can't believe it 60 bucks. Just keep messing with it you'll figure it out!
