Identification of problem for my PC

[niefeng87]

Hi all,

I would like to get some advice from you guys on the problem behind my PC.

Background:
1) My PC was previously having a lot of auto-restart problems, mainly due to my graphic card being faulty. I have sent it for repair, but the same old problems came back after a few months despite having repaired.
2) Now my graphic card is officially spoilt. I can use the PC when I plugged into the integrated graphics card on the mainboard. Just as I thought there won't be any auto-restart issues, it came back to me again.
3) PC will auto-restart itself from time to time. It does not restart within the same intervals, but usually after long hours of usage. But once it restarted by itself, when I try to turn on the PC subsequently, the restart issue will appear very frequently (e.g within 1 - 5 minute of usage).

Previously I thought the only problem lies behind my spoilt graphic card. Now due to the symptoms noted, I am quite clueless on the exact problem behind my PC.
1) Faulty power supply? How to confirm this because my PC will still run fine for quite long until the auto-restart problem arise?
2) Faulty mainboard/processor? How to confirm this as well because my PC still runs fine for quite long?

I have purchased all my PC parts slightly less than 2 year back. I am still covered under warranty. Most of them are 3 years warranty, and my power unit is under 5 years.

If I were to purchase a new graphic card, which of the recent release is comparable to my MSI R7850 Twin Frozr? (Budget: S$250 - S$350). Which would be worth for me to change to? GTX760? My power unit is 500W, and I am not too sure if it is good enough for a GTX760.

Sorry for the wall of text. Hope someone can help!

hmmm... bro try reapply thermal paste on the cpu? probably cpu overheat after long hours of usage ma... Btw for gpu can try 270x slightly cheaper than 760 and should perform slightly better than 7850

1) Install a software (e.g. real temp) to monitor your hardware temperature. Once your CPU reaches unsafe temperatures levels (e.g 90º celsius) it will shutdown by itself before getting fried or start a fire. You will need to check thermal paste, contact between HSF and CPU is not loose, and airflow is not blocked to exhaust hot air, and intake cool air in tha chasis.

2) Run a memory test (e.g memtest86). If the memory holding kernel data is volatile it could produce random restarts.

Thanks for the replies.

clon33:
1) I downloaded Core Temp to monitor the temperature of my CPU, and the highest it went was 65*C, which was far below than the cap of 105*C indicated for my processor mainboard. Hence, I would think it's not an overheating issue?

How can I check that the memory holding kernel data is volatile, and how do I resolve it?

d/l memtest and copy it to a DOS bootable thumb drive.

go to bios change boot priority to that thumb drive.

Run memtest for 3-5 passes.

Google should yield detailed steps.

I think you might have to troubleshoot by changing around parts to pin point the exact problem. Borrow another PSU, swap some other rams, clean ur mobo to eliminate all dust. Since you already say your CPU unlikely to be the culprit, it might possibly be the motherboard. Also what OS are you using? Could it be that any programs or software or viruses causing these problems?

Best of luck

What I'm afraid is that my CPU has dropped in its quality that it can only resist 65*C. Just some random guessing.

I am using Windows 7, and I don't have many programmes installed. Just Office and some games related ones.

I can't find anyone to spare me parts to test ><

I'll try to run the memtest once I get a USB.
