My systems hangs after around an hour of gaming. After a hard reset, it doesn't power up. However, i'l be able to turn on the system again after a couple of hours. This started happening when i changed my harddisk from 500gb to 750gb.
Is this a cooling problem or power supply problem?
The following are some of my system specs.
- Gigabyte ep45 ud3p
- gigabyte 9800GT
- Seagate barracuda 750gb 7200rpm SATA
- andyson 500W PSU
- CM Centurion casing
No overclocking done. Stock cooling. All help is greatly appreciated.
