i just set up a pc with the below specifications:-1. Intel Pentium 820 D2. Asrock motherboard with PCI-E and SATA23. Seagate 80GB SATA23. MSI X550 128MB DDR PCI-E GPU Hypermemory4. Kingston 512MB DDR-2 RAM5. Lite-on Multi Recorder 6. Win XP Home SP2I have a problem which is it hangs frequently althought i used Noton's One button Checkup to test the PC. This happens when i leave the com idle for a few minutes. I haven't try reformatting it as it takes much time to reinstall all my programmes. Is it due to the processor overheating? Hope you guys can help me to solve my problem.Thanks

[quote:a0bf2853d6] 3. MSI X550 128MB DDR PCI-E GPU Hypermemory 4. Kingston 512MB DDR-2 RAM [/quote:a0bf2853d6]Here is my theory. Unless your motherboard has slots for both DDR and DDR2 Memory, you are using one of the wrong memory chips. From your specs, you did not give enough info to determine exactly which Asrock motherboard you have. In most motherboards, there is a section for DDR memory chips and a section for DDR2 memory chips. For example, in my computer, there are two (2) blue slots for DDR2 and two (2) yellow slots for DDR. If your motherboard is not configured like that, the system may be conflicted.The first thing you should do is consult the owner's manual of the motherboard to make sure as to which type of memory you should use. If, in fact, you should only use DDR memory, take out the DDR2. Secondly, I would immediately buy an additional DDR chip, maybe upwards of a GB.Conversely, if your motherboard is only compatible with DDR2, take out the DDR chip and them buy an additional DDR2 chip.Some motherboards specifically say, "Do Not Use DDR memory and DDR2 memory at the same time." The best analogy(sp) I could use would be when battery manufacturers say not to use two types of batteries in any electronic equipment.

jiashiuanI think the MSI X128MB DDR PCI-E GPU Hypermemory that mphenterprises mentions is his graphics card. If that's the case, then there should be no conflicting memory problem.Since he specifically asks about the CPU overheating, I'm wondering if he's overclocking it, in which case, that could be his problem. The solution would be not to try overclocking it.It looks like he may have built the system himself. If so, did he place a cooling fan or heat sink on top of the CPU, and if so, is the fan working, and/or did he use enough thermal paste between the two components to allow the heat to transfer out of the CPU?Another possibility: Was the system working normally until recently, and if so, did the problem start happening after installing new hardware, or installing or updating software?If none of the above apply, I would check the system for a virus, or other malware. Don't use the antivirus already installed since the malware may also have infected, or is stopping your program from identifying it. Try doing an online virus scan at Trend Micro's website HERE .

MCBarker:Very good catch. I did not notice that until you pointed it out. Thanks for the heads up response.

hey guys. Sorry for the lack of info. Yes, i built that com myself and its not the first one i ever built. And this is the only one which gives me problems. The motherboard is Asrock ConRoe945PL-GLAN which runs on DDR2 memory. About the thermal paste, i use the processor out of the intel box, meaning its the stock coolling which consist of a alluminium heatsink and a fan on top of it. I asked around about my CPU overheating, they said that if it overheats, the com will reboot itself. But the problem is, it will freeze forever and will not even reboots itself.About installing softwares or updates, I downloaded every available windows updates from microsoft. And it runs well after i shipped it to my aunt. She said she didn't install anything just basic mail checking and net surfing thats all. So... yeah, i'll run a test from Trend Micro and see how it goes.. Anymore suggestion about this problem? I'll really appreciate it. Thank you.
