Computer randomly resets

[Renendaru]

Just installed a new Motherboard, Processor, and graphics card, but the computer will randomly restart itself, no warnings, nothing. If I try to open any game that used 3d graphics, it resets itself. If I leave it on, it resets itself in a random interval.

Card is Ati Raden HD 4200, graphics.

And the CPU and motherboard?

Are you sure you followed the steps correctly in attaching your heatsink? If the heatsink didn't come with a thermal substance already on it then you have to apply your own!

Restart your comp, go into the BIOS and look through the menus till you find one that displays your CPU and your motherboard temperatures? What do they read?

 

[Renendaru]

AMD Athlon(tm) II X3 435 is the processor.
GA-MA785GMT-UD2H is a Gigabyte motherboard.

I'm pretty sure the issue is the power supply, since it's only a 500w Power supply, with the new motherboard and processor, and graphics card installed.

500w is plenty for that. Check the temperatures. If you can't find it in the bios then download SpeedFan and check it out. Definitely sounds like a heat issue to me.

 

[Renendaru]

Well I'm looking at it and it's saying the temperature is about 27 C, but it will spike really bad at times up to temperatures that are dangerous for the computer..

27C is very low - room temperature low (80º f), what temp is that? cpu? also, does it give you a BSOD (blue screen of death)? any errors on that screen that you can see?

I used to get a blue screen of death, but as of late it has not appeared. When I did get them it was talking about my video card, but it's perfectly fine, I tested it thoroughly. After that, an hour, the BSOD's dissapeared and now it simply resets itself.

 

[Slapshot136]

after this "update", did you go get new drivers for everything (graphics/motherboard atleast?)

 

[Renendaru]

The drivers I have are from the disc that came with the motherboard, ATI had no updates, motherboard is at newest, everything is at the newest version.

 

[sqrage]

By "dangerous" temperatures, what do you mean?

And are you sure you're looking at the correct field? It's typically Temp1 not Core0 core 1 etc. that is important.

 

[Renendaru]

Well, I made it so it would show the BSOD now... Apparently a graphics error. Might be a faulty card, so what should I do then.

 

[sqrage]

I'd check the temp of the video card. If it's alarming or even if it isn't, I'd RMA it.

 

[Slapshot136]

just a FYI - there is no "card", the 4200 is integrated, meaning it's the motherboard you would be RMAing, and you would need to take out the CPU + memory first

you might just be better off buying a cheap graphics card

edit: you said you bought a card, what card did you buy? the 4200 is not a card and is integrated into the motherboard?

 

[Xorifelse]

It's most likely the PSU.

 

[DarkRevenant]

It could be any number of things.

1. A spiking PSU or insufficient PSU can cause random restarts.
2. A non-professional-level motherboard coupled with a horribly faulty video chip/card, or any other device in the expansion slots, can restart when the device fails for whatever reason.
3. Overheating CPU, video card/chip, or RAM will cause a system crash, plus a restart.
4. A motherboard-connected device that is rocked out of place, not firmly in the slot, or wiggled sufficiently so that it loses connection with its host, will cause the system to instantly crash.

A while ago my computer would randomly restart if I tapped the case. Eventually I got fed up and wiggled each component in turn. The computer apparently shat itself when i poked the RAM.
