DSTM

In did one about a month ago. Trying to remember what tut. It was a non format reinstall That's the one I used.Remember now, Bill

Tony, If you highlite :"restricted services" (not the arrow) then "standard profile" shows. You are clicking on the arrow

I am on windows7. I don't underatand

6am no sleep. Later guys.I am exhausted.

I would have thought sfc /scannow would have correct any file issues.Bill. Fix your Scannow, Tony. http://answers.microsoft.com/en-us/windows/forum/all/sfcscannow-message-could-not-perform-requested/ba0e2211-bbc9-4ba6-9d19-c546bfb17785?auth=1

Hi Tony. Are your d-word numbers here the same as mine under standard profile? Far right.

Under firewall rules there are about a hundred entries, Bill.

Hi Tony. You said the McAfee firewall wasn't on so can't see how that could be the issue. In the image I posted and stop when you highlite firewall, are your entries the same? You went too far. You can disable group policy and see if that works. http://www.computerstepbystep.com/group_policy_windows_7.html 2 more things I would try Use the program "Everything" by void tools and remove every McAfee entry on the computer. If there is an entry that won't remove then use an unlocker Run sfc /scannow to make sure system files are intact.

I will research this further

Tony. See if yours is the same as mine.Note I highlighted (firewall)

I will have a look.

Hi Tony. I read this. You can reverse if it doesn't work. The registry key you want to target is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\ Make the DWord = 0.

Good information. Thanks Cindy.

You can change the Boot order by pressing F8 or F11 repeatedly on Boot up, and get a "make default" option. Saves going into the Bios.

Hi Pete, reading your post I think I follow. My Bios is prob different to yours. Try this and see if it works for you. The Bios is Open. You are in "Advanced Mode" You have used the down arrow Key and you are at the bottom with "USB Configuration" highlighted as an example. At this point you are finished with "Advanced Mode" and wish to go to "Security" mode. DONT press the "Escape" Key.. Simply use your "Right Arrow" Key and watch up the top. Every time you press the "Right Arrow" Key you will advance one mode up the top till you reach "Security" By pressing the right arrow key you will automatically EXIT the mode you are in. Try this and tell me what you get? I am using a EUFI BIOS.

Tony, I think what Peterr means he has the BIOS open and navigating he hits the escape key to get out of a sub-mode and the escape key doesn't always work. That is correct, Peterr. It all depends at exactly what point you are in, what sub mode, and what option box you have open at that moment. My advice is you don't need to go into the Bios as your OS is installed, and you are not Over Clocking, best to press the Exit F10 Key and choose the option to leave everything set as Bios Defaults. Not necessary to go into the Bios unless Trouble shooting. Easy to mess for the inexperienced. EDIT. I missed your last post,Peterr. I was posting.

Hi Peterr. Your operating system does recognize the ram you have installed. Some power supply fans can be noisy. How long ago did you have the 5oo watt Power Supply installed?

Hi Peterr. This is the correct Power Supply you are after. http://www.amazon.com/Genuine-Dell-Systems-Compatible-Numbers/dp/B009G28TOW This seller looks OK. From Cleveland OHIO so delivery should be quick. http://www.amazon.com/sp?_encoding=UTF8&asin=&isAmazonFulfilled=&isCBA=&marketplaceID=ATVPDKIKX0DER&orderID=&seller=A28J86NSXNXWOU&tab=&vasStoreID=

I must get some photos and post. This cat loves water.

My cat "Lucie" does some unusual things for a cat. When having my bath my cat sits at the door and meows till I let her in the Bath room.Jumps straight in the water and wants to be washed. One of us washes her, rinses her off with the shower spray, then it's on her own towel on the floor and meows till we dry her with the hair dryer. No other cat I have ever had would go near water. Puddles of water in the garden after a storm will walk through the puddle instead of around it.Wants to be washed daily if we let it happen.:big_grin:

Hi Peterr. The specs on your computer are quite good for a home computer. I would buy a Power supply myself as they are not expensive. Prob around $40 plus fitting. I would not under any circumstance keep using this computer till the Power supply is replaced. Definately NOT without going into detail. Would be crazy to keep using till it no longer boots up. Next step is to get every number off your power supply so you do get the right one. There will be identifying numbers on it. Post all the numbers and we can guide you into buying the correct Power Supply. This is a small $$$ amount to spend on your computer. We can only advise but the ball is now in your court. Repeating I would not use this computer till the power supply is replaced.

Some normal power supplies come in a reduced size which should be able to custom fit. Cindy would have more of an idea as she has worked on Dell Computers for some years. Thanks Bill.:)

Hi Peterr. Windows recognizes your graphics card drivers so that's OK. Your problem is your Power supply. The rail readings are so low it a wonder the computer boots up. Your 3.3v is reading 2.832v Your 5v is reading 2.843v Your 12v is reading 11.232. This I believe is the cause of all your issues. When a Power supply gets below 11.700v on the 12v rail every hardware component on your computer is trying to function with too little wattage, hence crazy things start happening like flickering your having.Not only that, all your rail readings are down badly. Next problem is Dell power supplies are a smaller size than normal power supplies so that causes a problem locating one. Your PC came with a 460 watt power supply. Maybe staff can locate one on EBAY for you. Then you need to take the computer to a computer shop to have it fitted. Compare my rail readings in the example I posted compared to yours and it's obvious your Power supply is Cactus. What do other Techies think?

Hi Peterr. What Bill means you have 4 slots. Two will be one colour and two another colour. Normally say slot one and three will be matching colour, say Black. Same colour slots take same size ram. Can you follow this example?

Thanks for that information,Peterr. Will help in our Diagnosis.
