Hi, i recently had a problem with my pc where it kept turning off or locking up. I fixed it by increasing the tdrdelay number now i have another problem. This just started happening yesterday. My hdd light will go off completely & than my computer freeze's & it alway's does this after awhile no matter what i'm doing. I have looked all over the internet & other people have a problem where there light stay's on i stay's solid red but mine just comepletely turn's off than i here a buzzing sound & have to hard reset. My specs are
geforce gtx 660
intel core i5-3570k
corsair cx 600
ASRock Z77 Extreme4 i also only had my pc for alittle over 2 yars & i accidentally uninstalled my onboard gpu which was a intel 4000 don't know if that mean's anything or not.

1st) Make sure the cables to your HDD are connected properly. Also remove, clean(google if you don't know how to), and reinstall your RAM.

2nd) Run an HDD Check.

3rd) Run a memtest.

4th) Monitor the temperatures of your PC parts including CPU, GPU and motherboard and see if there is anything abnormal.

This will hopefully help you find out what's causing the problem. I hope I was able to help. Let me know if you have any questions.

Hi, thank's for rplying. There is nothing wrong with the temps but i did run memtest once & it stopped but the number's kept moving. I will try the first two & get back to you. I should also say everything run's fine into that happen's.

I did what you said now i'm just waiting. I have a feeling i'm going to have to rebuild again though.

I found out what the problem was, i didn't have enough ram for the thing's on my computer. I deleted an anti-virus that i had & now it work's fine again.
