A7V8X - No monitor detection on cold boot

[WEG]

Need help !!

I recently purchased a computer with the Asus A7V8X motherboard. At about a rate of 9 out of 10, upon cold boot start up of my computer, the monitor will not be detected although it is booting properly. When I press the reset button, the monitor is detected. Here are my computer specs:

Asus A7V8X with serial ATA & Firewire
AMD XP 2400+
512 MB DDR 2700 RAM (333)
80 Gig Maxtor 7200 RPM ATA 133
ATI Sapphire Radeon 9500 PRO 128 MB
Samsung 171S 17" LCD Panel
OS - Windows XP

Any help would be greatly appreciated !!!!

Monitors are not "detected". They either work or they don't - or they are flaky. Check the cable condition.

Start with the basics. Make sure that your video card is dependable. Be sure that it's pushed in tight. If you have any doubts about the power supply, upgrade to a higher wattage unit (350V or more brand name - Antec, Enermax, Fortron, Sparkle).

You say that the PC is booting even when there is no display. Do you hear the hard drive grinding? Do you hear the Windows sounds?

Thx. for the reply !

I should clarify that the monitor is being detected, just that it goes into standy by mode. Once the power is reset, it runs normally. Yes I do hear the hard drive working and everything, I have even signed on to Windows without the monitor on. My power supply is 300 Watts which I'm sure is enough juice. Any other thoughts ?

What makes you think that a generic 300W power supply is adequate? That motherboard and CPU combo is a power-hungry one. Add the rest of your stuff and a 350W minmum is recommended. On top of that, you cannot trust generic power supply ratings. Only certain name-brand manufacturers can be trusted.

Ive had simialr problems in the past and still do to some extent, i have arrived to the conclusion its a weedy PSU. What i do is turn my PSU on at the wall 5 or 10 mins before i go onto the machine, tjhat way im not booting cold. usually this sorts it out, but really a better PSU is needed :(

Thx. for your reply guys !!

Hmm . . just went to check out my power supply. I do have a 350 Watt power supply. Do you think I need more ? The store I purchased it from is willing to put in a 420 Watt supply in exchange at no extra cost. Could it be the video card at all ? The AGP slot ? What about the BIOS ? How do I check what version I have ? I think the current one for the motherboard is 1011.

I've tried to impress upon you that the brand of PSU is more important than the rating. Read the article that I linked you to.

It's quite possible that you just need to reseat your AGP card.

Bill,

Thx. again Bill ! I am going to check out what the brand name is and also what other PSU's they offer. I am also going to reseat everything and make sure everything is securely in.

If its free i would take the 420 to see if it helps, if so, then you sorted it free. If not you then know something else needs lookign at but you got a bit more wattage for free.

As BPB says though, often with PSU's the brand is more important than the wattage, Antec, Enermax, Sparkle and Hiper are all very good brands and well worth their money
