Thread: Booting problem

I recently had to change both my PSU (Corsair TX 650) and my HDD (Seagate 500GB 7200.11 ST3500820AS) which had become faulty. The reason for the fault is still unknown and my assembler has no idea either. The earthing at my place is fine. However, since the time my new PSU was installed (last two days), the PC has a strange booting problem. The power LED (blue) stays on, but the hard disk LED remains off. I get a total blank screen. There are no error beeps. I have tried fitting the RAM in alternate slots, but the problem still persists. Sometimes, when I restart the machine it boots fine and at other times, the usual problem. I have Windows XP and Vista Ultimate' setup in a dual boot configuration. My system specifications:


C2D E7300, ASUS P5Q-E Mobb, Palit Radeon HD4870 1GB DDR5 GPU, 4 GB Corsair 800MHz' memory, CM690 cabinet, Dell 19-inch LCD, Emerson Liebert 600 VA UPS. Suggest a viable solution. I'm getting really frustrated.

You mentioned that your power supply and drive got spoilt. Some of the components might have also been damaged due to the same problem. Try powering up the PC while connected to the power point bypassing the UPS. See if it boots. Also, check for loose connections. Check the power connectors going to the motherboard and the graphic card.
