Computer Help Needed. Computer Randomly Turns Off!

I need some serious computer help here. If you can help, great. If not, refer me to a place where I can get some help!

Here's what happens. The computer randomly turns off. It's like someone just pulls the plug. I said it happens randomly, but it tends to follow a pattern. Sometimes. For example, it tends to happen when I use IE, and especially when I try to scroll. But it also happens when I start flight simulator. I don't know what to make of this problem!

I have tried a lot of things to fix it.

First of all, here are my comp specs:

Soyo P4VDA (PVDA) motherboard 400mhz fsb
Intel 2.4 ghz processor
512mb PC2100 ram
Nvidia MX-440 video
Creative SB live! audio
2 CD rom
2 hard drive
300watt power supply

I tried flashing the bios. no help
I replaced the hard drive. no help
I scrubbed the new hard drive, started from scratch with WINXP. no help
It isnt the Blaster worm. I started from scratch and it still turned off.

It turns off randomly under all operating sytems. 98, 2000, XP.

It sometimes turns off before it even gets past the initial memory testing when you start it up. But once it has successfully loaded windows once, it doesnt normally do that anymore.

So I am wondering what the problem is? this is so frustrating!

Thanks to everyone who can help!

Shawn

Have you used the Blaster Worm removal tool, to make sure it's not that? It can remain in the system even if you do a full restore from scratch - believe me, I speak from experience  Smile

Well, it can be alot of things, I dont think its the Blaster worm because he stated he replaced the hard drive. The best guess would be to replace the power supply, that is most likely the cause, but it could also be the motherboard, and in some extreme cases the processor, but I would try and get your power supply replaced and then see what happens.

Before you replace anything, open the computer case, and continue to work, watch the fan that covers the processor, if it is not working properly, then as soon as it gets hot, the computer shuts down. This happened to me, so it is a good place to start before you spend a load of cash.

I was going to suggest that your computer was overheating, but Artsyman beat me to it.

I had this problem on a FORMER computer and it was due to the processor and memory chips all getting too hot.

I'd suggest it's your power supply. A lot of motherboards these days are quite power-hungry, and a most new cases I've seen over here now come with 420W power supplies as standard. I was lucky with my case, it originally shipped with a 300W PSU and lots of people had trouble with shutdowns and even blown supplies - I didn't have a problem but as soon as I found out, I upgraded it to a newere 350W PSU. Whether it's faulty or not, if you plan to add anything else to your system in the future I'd suggest at the same time you upgrade to at least 350W.

I have come in a little late on this discussion, but as an IT geek, I will throw in my two cents  Smile/happy/getting dizzy

By the sound of it, either could be right. I would follow the suggestion of watching the fan for the CPU if possible. I happen to know my Dell p4 just has a massive metal heatsink. I lean towards the power suppy. With the system you described, it sounds barely adequate, and if it is started to wear out, may no longer be adequate.

I was thinking fan when I read Artsyman's comments, he beat me to it.. I did computer tech support for 3 years and more than once had to replace the fans. Also the obvious thing is to make sure your computer is not crammed into a small cabinet or against a wall, and the back of the computer has breathing room.. and that the fan opening is not clogged with dust or debris....

Good luck.

Don´t have too much experience with Wintel hardware; But if there´s a failure of CPU cooling you´d probably just see it "hanging in mid-flight" without switching off. When the CPU is stopped, it won´t produce much heat any more. (At least some AMD CPUs are reported to actually "blow out" when they´re overheating, Intels just slow down or shut down.)

When the computer actually switches off without any message or warning, it looks a lot more like the power supply (overload or defect).

It could also just be a loose power plug, by the way... I had once wondered why the keyboard and mouse showed no response any more and I was close to rebooting the system before I noticed that the keyboard plug had just fallen out of the socket...  Wink/being sarcastic

Well, now I feel really stupid.

I don't have any more powerful power supplies laying around here. Well, I put a 200W one in (I didn't expect it to be powerful enough). And lo and behold.... the problem went away.

I feel so stupid!

So I guess it was the power supply's fault. I'll have to get a new one then.

Thanks for the help, lol.

No problem!, well, you said you put a 200W PSU in there, it should hold out for the time being, because this is a been there done that situation for me, so the 200W should hold out until you can get something bigger , I suggest atleast 350W, as the prices for PSU's are gradually lowering.

Dan,

What do you think of this PSU?

http://www.compusa.com/products/product_info.asp?product_code=50350641&pfp=SEARCH

It's kind of cheap compared to the competition... but a PSU is a PSU is a PSU, right? Or is this cheap and is it gonna break down quickly?

Thanks

Shawn

Well, it all depends on the inards of the PSU, but this one has a 2 year warranty, so if anything goes wrong youre covered, but the rest sounds good, but the only thing that bothers me is that it doesnt say how many connectors for extra drives, etc on the specs page. But besides that sounds good, and actucally I have been running on a 150W PSU after my 350W PSU died on me for about a month so I think as long as you dont restart constantly you should be fine.

As a person who builds systems, not all PSU's are equal. A lot of the cheaper ones _claim_ they make a certain wattage but only peak at it, often making a lot less.

I would recommend Antec

http://www.antec-inc.com/us/pro_powerSupply.html

That is thier power supplies. Antec is almost literally the best hands down in the market.

Well, I use Antec PSU's and I have been using them for a while now, but I looked on that page and even though as you said they will only sometimes only peak at it, I saw nothing wrong with that PSU said it would do, and it does have a 2 year warranty so if anything goes wrong, it will most likely be covered. And the thing about PSU's is that its all in the capicitor(cap), the companys will most of the time use double the wattage just to be safe, (i.e the cap in his PSU will probally be 700Watts) so I dont think that will be a problem. And my father is a I.T, and we make many repairs of this type, so I guess you can say that is my source.
