Which of these components are most probable defective within this situation?
After it freezes, the computer has to be unplugged and replugged to turn it on again; the power button and reset button do not work.
I've narrowed it down to:
Motherboard
CPU
Power Supply
It can't be the RAM because I already tried replacing it and it didn't fix the problem.
Specs:
2.00 GB RAM (Crucial / PC2-4200 / 533MHZ)
Pentium D Dual Core 940 (3.2 GHZ)
Biostar P4M800 Pro-M7 Socket 775
250 GB Samsung HDD (7200RPM)
Nvidia Geforce 7300 GS
Windows Vista Home Premium
480 Watt PS
Answer:
If I be troubleshooting this, I would try the following to rule out the CPU (which more than likely it isn't the problem unless its getting too hot within which case it is installed incorrectly or you didn't coating back the thermal grease strip or you peel it off). You can go into BIOS and turn past its sell-by date your internal cache. I don't know your Mobo but it is in in that somewhere. If you do that and the problem goes away next your pro is messed up. **If you do this your computer will be 65% - 70% slower**
Anwyay, for your power supply, if the computer comes on and is not entirely flakey and your OS loads and it doesn't reboot suddenly and give you BSOD's upon boot up and if your diag lights on your Mobo are ok later continue on chronological this. You can disconnect some non essentials to see if it lasts longer, but I would really look at the Mobo. More than predictable if you are freezing it is either memory or the mobo. You already ruled out mem so looks approaching you could have some FSB issues or firmware issues. Boot into risk-free mode and see if you experience the same problems after a apt period of time. If you don't later you probably just entail to update your drivers to accomodate Vista. You may want to find out what kind of chipset your mobo have on it and download the latest drivers for it.
The biggest flag that I see next to your post is that you did a fresh install of Vista. Can you see how drivers could help next to this situation? Also you can download the latest NVidia drivers for your system. Just hang on to trying until you can leave the computer on for a continous length without freezing.
Another point that has other been a problem is ACPI on the motherboard. Be sure to check that out and disable it when you see it. Also be sure to update your motherboard BIOS to the hottest rev as the PCI bridge drivers for Vista could be incompatible with the contraption level logic of your BIOS firmware.
I hope this help you out.
I think it's the Motherboard.
try to replace the motherboard, breed sure you place your hsf and your procesor tightly, dont forget use thermal paste, also try to plug your bump into different slot
i would say cpu because i have the same problem from a gateway laptop and they told me thats what it be when i braught it in
it could be going into hibernation mode and since the power button or reset button doesn't work,you own to unplug it to restart it to get it out of hibernation mode.walk to the link below and read it.it should oblige you.i would disable hibernation. Click Start (or the Windows Logo) -> All Programs -> Accessories.
In this folder you will see an entry labeled Command Prompt. Right-click this entry and select "Run as administrator."
At the command prompt, type "powercfg -h off" (without the quotes) and press Enter.
Unfortunately there's no confirmation message to indicate whether or not you were successful. But we can confirm this for ourselves by typing "dir /a:h c:\hiberfil.sys" (again, short the quotes) and pressing Enter. If we were successful afterwards you should get a message which say "File Not Found." We have simply disabled Hibernation and freed up some disk space. But if you decide that you want to see Hibernation later you can do so by following steps 1-3 again, but this time specify "on" instead of "off" during step 3.Another item if your power and reset buttons are not working shift into your documetation for the motherboard and see if the wires came stale,or they r hooked up wrong.
Its probably overheating , you could set the 32 or 64 bit " number of colors ", selector to 32 , it might cool it off , and you could turn stale all of the, " special optical effects " for example , the way the Vista operating system screen all look , smaller amount flashy in nonspecific it cools it off , also quit the door off the computer when you are using it , but dont touch anything within the computer , you might get shocked and after accidentally break it . When the computer is off , dally 10 minutes or use your judgement and touch everything in the computer beside your finger until you notice if anything is reheat or hot , the rest of it should be cold , remember the location and find out what part it is by looking at a picture of a motherboard , surrounded by a magazine, or at websites that motherboard manufacturers operate, a picture beside arrows telling you what the parts are , when you find out what it is progress by "pin count", the number of electric contacts you can see , replace it if its removable with something thats get a higher Bytes number , for example, MegaBytes or MB's , it act like a cool down device , I would suggest something partially - way between the MB's for the cog thats in within now and the maximum MB's available for that fragment , buying the cheapest part is best , find out if the website you buy the constituent from gives you the Program CD's and printed instructions that sometimes come near a part , some websites dont present you those because they think they can put on the market the parts even cheaper to you than , other sites but neither site always tell you , trying the first 2 things I mentioned are easy as hell to do , in recent times look around on your screen after youve have it off for a while and turned it wager on on , look for something where on earth you click on different things till you find those 2 settings and change them , than youre at your lesiure near the 3rd thing . The monitor freeze is usually the result of hardware parts overheating and after jamming the monitor Element causing what is close to nasal congestion , or ice - freezing .
