PC shuts off if case is closed

Have a PC Win XP pro 32 bit i put together for a DVR. Its a P4 3.0 with a Asrock 4CoreDual motherboard, 1 gig of ram (2 sticks of 512) PNY Geforce 6200 AGP vid card. Has 2 hard drives in it. A 120 gig western Digital serial and a 500 gig western digital serial drive. A lighton DVD drive. 120 gig is boot drive 500 is were TV recordings go too. Have 3 video Captures cards in it. Two Hauppauge 1600 and an older PVR-150. It shut itself off a week ago. I opened the case right away and it was fairly hot inside, nothing seemed paticulary hot. I tried to restart but it only went for a few seconds then right off again. I let it sit for a few minutes and it restarted and continued to run for the next few hours BUT i left the side cover off case. I left cover off for the last week with no problems.

I ordered a new power supply because the one i had was a cheapy one, which i thought might be the problem, replaced it with an Antect Green power supply, 380watt. Closed case up and after about 2 hours it shut itself off again. I opened the case let it sit a few minutes then it would restart and ran fine for the next few hours i needed it. I got to get some software to monitor temps, any recommendations?

It must be a heat thing because it seems fine with side cover off of case. There is one case fan at back of case. Case is a midtower and PC sits in the open about 8 inches from wall.

Trying to figure out what might be the cause of shutdown. I had this system running for almost a year now with no changes and it did fine even in the summer were the inside temps in house were much warmer, this was with the case cover on. Come this summer iam afraid its going to be a problem even with side cover off case.

Any guess at what might be cause?? I do have another motherboard i could put into it,, a MSI P6N SLI Platinum but i would need to then get DDR2 ram as current uses DDR ram and new video card as current one is AGP and MSI board has PCI express slot. Both motherboards of course use same socket 775.

Really want to keep cost down as its just my homebuilt DVR running SageTV. I dont need that powerful a system to run SageTV.

What would you do under these conditions, looking for advice.
 
Are you sure the case fans are working?

Check the front grill to see if it is clogged with dust bunnies etc...

I would say it is def a heat issue if it will run fine with the case open and not with it closed. Those capture cards can get very warm when operating normally and a reduction in air flow they will really generate some heat. Do you have a temperature monitoring program, if not get one and watch the temps with the case open and closed.
 
No i dont have a temperturing monitoring software. I need to get some. Any recomendation for software?

The fan on the back of the case is working ok and i will check the front cover on case to see if its clogged at all but i dont think it is. I might have to get one of those big slow rpm fans for the front. I want to keep the noise down. The fan on back of case is one of those quite fans but it has been good enough for the past year.

Thanks for the suggestions.
 
I think ASRock may still offer a motherboard that can use cool-running Core2 (or similar AMD) processors along with AGP video cards and DDR1 memory. I owned one of these and it worked fine, but the two memory slots limited it to 2 GB of DDR1 memory.

Here's one:

It's a VIA chipset, though. Mine had an Intel chipset. It'll take either DDR or DDR2 memory, an AGP video card, and an Intel Core2 Duo or Quad processor. It may not run 45nm processors. I see at least one reviewer who's running an E3200, so maybe it does. You could swap to this motherboard and a Celeron E3300 processor four around $100. You can get a bit back by selling your old MB and processor on eBay if they turn out to be OK.

Yes i could get another motherboard BUT iam not sure that will solve my issue. Since i do have another socket 775 motherboard allready, the MSI p6N SLI Platinum i might as well go that route, that way i replace the video card and memory at about the same coast as buying a new motherboard. Video card at about $65 plus memory at about $30 for 2 stick of 512 for a total of $95 with new ram and video card. This way almost everything is new except hard drives. Power supply is allready new.

Just not sure i want to do this if i dont have to.

I will download some software later tonight to monitor temps to see if any paticular part gets excessivly hot. If nothing does i guess i will replace the parts i mention above. Just hate wasting money. It could end up being one of the hard drives too and then i would have wasted all that money for nothing. Now that would get me mad at myself.

Installed Speedfan for monitoring temps. With Case open it shows the GPU at about 55 to 60C and it doesnt ID the cpu but shows 2 winbond temps not sure what is what? one is at 45C and other is 56C,, hard drives are both at about 38C . This is all with the case open on side. About 70F room temp. Iam concerned at what ever is the winbond at 56C and not sure if the GPU is supposed to run that hot either. Its a Geforce 6200 256 ram, the heat sink has no fan on it its just a heat sink. Iam going to give whole case a good cleaning and try tommarrow with case closed to see what temps i get.
 
Your GPU is pretty normal. If you can attach a fan to the heatsink, it would probably run 5C cooler or even more. 56C and 45C are pretty warm for anything other than the GPU. My Core 2 Quad idles at 14C and gets up to maybe 30C when gaming. My motherboard usually sits around 25C and goes up to maybe 35C when gaming. Neither of the temps that you have would do any damage, but they should run much cooler than that.

Check to make sure that both the fan on your CPU and the fan that is directly on your motherboard (if it has one) is working correctly.
