✔ Best Answer

first thing take off side cover and using canned air blow out all the dust and even the power supply real good then check it.You may have to go to dells website to find out how to open your model cause some i'v'e messed with are where you push a couple of buttons to open them.

"desk top:model 2LTW5J1" I googled that model number to find the specs & only got 3 hits, 2 of them being yours. Then I realized that it's probably the service tag number. I went to the Dell site & sure enough - Service Tag: 2LTW5J1. Express Service Code: 5673563389. Shipping Date: 5/1/2009. It's a Vostro 220 Mini-Tower; not quite as old as I suspected. http://www.dell.com/support/home/us... http://www.dell.com/us/dfb/p/vostro... Here's the basic specs: Core 2 Duo E7400/2.8GHz,3M 1066FSB 2GB Non-ECC 800MHz DDR2,2X1GB 16X DVDROM Drive 160GB Serial ATA Hard Drive 7200RPM, 8MB Cache Dell E2209W Widescreen 22.0 Inch I doubt the problem is overheating. More than likely the power supply is failing or possibly one or more of the motherboard capacitors. Check for bad caps when you clean the dust from inside of the case. Some are more obvious than others...here's some examples: http://www.markdigital.com/wp-conte... http://paulrepair.com/blog/wp-conte... http://www.mikerepairscomputers.com... It appears the power supply is a standard ATX12V. Keep a lookout for the Corsair 430W. It's an excellent unit & regularly goes on sale for about $20 after rebate.

Thank you. You've been very helpful. Regards, Eldon

Great advice. I bought two cans of pressurized cleaner. Used one can on the subject computer. I throughly cleaned the interior components. Although, I did not remove the power supply shield, but cleaned it the best I could. from the exterior. I left the computer "on" all night. It shut off by itself. But then, I did not have all the cables connected, just the power cable. So, it had its own reason for shutting down last night and which reason I'm not aware of. The unit, as I write to you, is working fine. I called the Dell factory reps. Their conclusion-bad motherboard. "We will sell you a new computer. Forget about the one you now have. Incidentally, the computer sits on carpeting. I have a dog. Unit had too much lint and "dog hair" in the interior. Thanks again. You are smart and practical. And, your impartial advice sure beats the predator's advice. Regards, Eldon

Your very welcome glad i could help out. Davidw

Hello David, I got too carried away on my hopes. This morning, I turned off the computer in question as I wanted . to clean the two side by side computers with canned pressurized cleaner. I didn't want dust entering the newly cleaned computer in question.So, I moved the computer in question to another location. Moved it back to its former location, I tied to start the computer. It would not start. So, I'm back to square one. Maybe an intermittent power supply? I need to check the power supply voltage output. See what I have. Rgegards, Eldon
