Computer won't post

[theforce]

Hi, I have the same setup for about 2 years and everything was working fine until today. I switched on my PC, the motherboard lights switch on, all the fans are spinning but it wouldn't post.

At first l thought it was my cable or monitor. I hooked my laptop on the screen and the screen works fine with it using HDMI->DVI cable. Then my suspicions turned to my dedicated video card. I removed that as well and hooked the HDMI cable on the motherboard's HDMI output. Again the same problem. I tried clearing the CMOS with no successful result. If l only connect the monitor with no USB devices it sometimes manages to reach a prompt telling me that it is using fail-safe settings and that l should press F1 to enter setup or F2 to continue but since no usb devices are connected l can't do anything.

I am at work now and l will start removing devices, test PSU when l get back home.

Here are my specs:

Motherboard: MSI Z77A-GD55
CPU: Intel i5 3570K
RAM: Corsair Vengeance arctic white 2*4GB
PSU: Corsair TX 750W
GPU: ATI Radeon 6850
HDD: 1 ssd & 2 mechanical drives

Everything was running at stock, only using XMP profile for the RAM.

it usually prompts f1 if it hits an oc error

idk if your overclocked at all? best thing would be to clear the cmos and take it from there

Never overclocked my current system. Only overclock that is active, if any would be the turbo that automatically overclocks the CPU from 3.4 to 3.8GHz and the XMP profile for the RAM.

I will run more tests when l arrive home.

Thanks for the replies. Used a cheap cooler for a year until it got replaced by a big noctua cooler. The CPU temps were fine. I returned home a while ago and the Pc was working, sort of. Managed to get into the bios and replaced the initialization from PEG to IGP. Saved the settings and rebooted. It managed to load Windows and then l shut down manually. I tried cold booting thinking the problem was gone but again, the PC boots and nothing shows on the screen. I am thinking that the motherboard is fubar

The saga continues with the local online shop telling me to send the motherboard directly to MSI. I contact the MSI "dealer" in Cyprus that explains to me that a motherboard isn't a desktop product. I only bought the motherboard from Cyprus to save me all the hassle of RMAing a product abroad, oh the irony.

If l bought the item from Overclockers.co.uk for example l could send it to MSI UK and it would be ok?
